DESCRIPTION OF THE INVENTION

FIELD OF THE INVENTION

The present invention relates to the technical sector concerning the industrial processing of liquid, cream, paste substances, in particular emulsions, such as for example creams, serums, oils, gels, balsams, lotions, etc., for the production of cosmetic, pharmaceutical, chemical or agri-food products.

For the manufacturing of these types of products, apparatus known as mixers or turbo emulsioners are used comprising a vessel internally of which the substances to be mixed and emulsified are placed and mixed to obtain a final product.

In particular, the present invention concerns a management and control system of a temperature internally of a mixer or a turbo emulsifier.

To obtain an emulsion between water and one or more oily or greasy substances internally of the vessel of the mixer or the turbo emulsifier it is necessary to proceed to a heating thereof and then to a mixing thereof using appropriate stirring elements.

And then, once the mixture has been obtained, and therefore the emulsion, i.e. the final product, it has to be cooled, and brought for example to a temperature close to the ambient temperature, before being extracted from the vessel.

It is therefore necessary to be able to vary the temperature by raising or lowering it internally of the vessel so as to carry out the various steps of processing and mixing, and the extraction of the final product.

DESCRIPTION OF THE PRIOR ART

Various ways are known for obtaining variations of temperature internally of the vessel of a mixer or of a turbo emulsifier, to carry out the heating, and then the subsequent cooling, of the substances present internally of the vessel. A first known modality includes the use of a jacket or container, which is arranged about the vessel and which is filled with water.

Internally of the container, in the lower part and immersed in the water contained therein, electrical resistances are located which are activatable to heat the water and thus enable a transfer of heat to the heated water in the container to the vessel and then to the substances present internally thereof.

The heat transfer therefore takes place in a static mode and requires a certain passage of time; further, there will be a heat gradient, i.e. a temperature differential, in the water present internally of the container, with the water directly in contact with the resistances which will reach a higher temperature with respect to the water further away.

Therefore the heat exchange during the heating step is not very effective further it is not possible to control or manage the temperature variation in a dynamic way, in the sense that it is not possible for the user to set temperature values to be reached in prefixed time intervals.

In other words, it is not possible to manage and control, and therefore vary, the heating curve of the temperature internally of the vessel.

Inside the container there is a serpentine circuit communicating with the outside environment via an inlet and an output.

To carry out the cooling of the substances present internally of the vessel, once the resistances have been deactivated, a cooling fluid is passed internally of the serpentine circuit, for example water at a low temperature of a few degrees above zero, coming from a chiller (refrigerator).

The cold water passing into the serpentine circuit cools the water present in the container and consequently cools the vessel and therefore the substances internal thereof.

In this case too, it is not possible to manage and control the cooling and thus intervene on the time required to return the substances or the final product present in the vessel of the turbo emulsifier to a temperature close to ambient temperature, for the extraction of the mixer or the turbo emulsifier from the vessel, in other words, it is not possible to manage and control the cooling curve of the temperature internally of the vessel.

Another different known mode for obtaining variations of temperature internally of the vessel of a mixer or of a turbo emulsifier consists of a jacket, also arranged about the vessel, which jacket is configured and predisposed to receive a fluid circulating internally thereof and having an inlet, for inlet of a fluid into the jacket and an outlet for outlet of the fluid from the jacket.

The inlet and the outlet of the jacket are predisposed to be connected to a supply source of a heating fluid, such as for example hot water or steam, or a supply source of a cooling fluid, such as for example cold water or another refrigerant fluid, coming from systems already present in the place of use of the mixer or the turbo emulsifier.

Therefore, when it is desired to heat the substances present internally of the vessel of the mixer or the turbo emulsifier to carry out the mixing and the emulsion, the inlet and the outlet of the jacket must be connected to a supply source of a heating fluid (for example a source of hot water or a supply source of steam) for the circulation of the heating fluid internally of the jacket.

The passage of the heating fluid internally of the jacket generates a heat exchange with the inside of the vessel and thus enables transferring heat internally of the vessel, by heating the substances internal thereof.

Once the heating has been completed, and at the moment when it is desired to cool the substances or the final product present internally of the vessel, first it will be necessary to proceed to the emptying of the jacket, by extracting the fluid utilised for the heating.

In the case of use of steam it will also be necessary to remove any condensation by injecting compressed air into the jacket.

Then, the inlet and the outlet of the jacket must be connected to a supply source of a cooling fluid (such as for example cold water coming from a chiller).

The passage of the cooling fluid internally of the jacket will enable generation of a heat exchange with the inside of the vessel, cooling the substances or the product present internal thereof up to the desired final temperature for extraction thereof.

This mode, though more effective in terms of heat exchange, and thus in the heating and cooling of the substances present internally of the vessel of the mixer or the turbo emulsifier, presents however some drawbacks.

In fact, the jacket must be specially designed to resist the heating and cooling pressure which are made available by using the systems and users present at the facilities of the final users who acquire and utilise the mixer or the turbo emulsifier.

For example, a user of the mixer or the turbo emulsifier can have available a supply source of steam for heating which supplies steam at 100°C at 1 bar pressure, while also having a supply source of water coming from a 4 bar refrigerator.

The jacket must therefore be dimensioned and designed to resist the circulation of a fluid internally thereof up to a pressure of 4 bar.

There exists therefore an issue of sizing and adapting of the jacket in relation to the systems and users present at the facilities of the final users.

Further, as time by time, for heating and cooling the vessel of the mixer or the turbo emulsifier, the jacket has to be connected to the various systems and users present at the customer’s facility, problems connected to contamination of the jacket can arise.

Even with this other known modality it is not possible to regulate, control or manage from the mixer or the turbo emulsifier the time necessary for heating and cooling the substances present internally of the vessel.

For example, it is not possible to regulate the time necessary for reaching the maximum temperature required to carry out an effective mixing and emulsifying of the substances placed internally of the vessel, nor the time that is needed to wait, during the cooling, so that the product obtained reaches ambient temperature, or the temperature at which it is possible to proceed to the extracting thereof from the mixer or from the turbo emulsifier.

In other words, in this case too, the user cannot set temperature values for reaching the preset time intervals, i.e. the user cannot set variations of temperature which must be reached internally of the vessel in a given time interval.

Therefore, in this other prior art modality, it is not possible to manage and control the temperature variation curve in the desired time intervals, i.e. it is not possible to manage and control the cooling curve nor the heating curve internally of the vessel.

SUMMARY OF THE INVENTION

The aim of the present invention is therefore to provide a management and control system of a temperature internally of a mixer or a turbo emulsifier that is able to obviate the above-mentioned drawbacks present in the prior art and described in the foregoing.

In particular, an aim of the present invention is to provide a management and control system which enables the user of the mixer or the turbo emulsifier to control and manage a variation of the temperature internally of the vessel of the mixer or the turbo emulsifier as a function of the time, and therefore as a function of the user’s own special requirements.

Therefore, with the system of the invention it is possible to indifferently control and manage the cooling and/or the heating (i.e. one or the other or both) effectively and as a function of the time, i.e. to control and manage the cooling curve and/or the heating curve as a function of the user’s own particular requirements.

The cited aims are obtained with a management and control system of a temperature internally of a mixer or a turbo emulsifier according to the claims.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to the accompanying tables of drawings, reference letter (S) denotes the management and control system of a temperature (for example cooling or heating or both) of a mixer (T) or a turbo emulsifier (T) according to the present invention, in its entirety. The mixer (T) or turbo emulsifier (T) comprises a vessel (D) in which substances are introduced (for example water and greasy or oily substances) which are to be mixed with one another and emulsified with the purpose of obtaining a final product, such as for example a cosmetic product or pharmaceutical product for personal care, etc.

For the purpose of mixing and emulsifying the greasy/oily substances with water it is necessary to carry out a heating to determined heating temperatures (for example 70-90 degrees) and then, once the desired final product has been reached, it is necessary to cool the product and return it to a temperature close to ambient temperature (or lower) before being able to extract it from the vessel of the turbo emulsifier.

Therefore the vessel (D) must be heated and subsequently cooled.

The system (S) of the present invention enables management and control of the variation of temperature, irrespectively of the cooling step or heating step, or both, of the vessel (D) of a mixer (T) or a turbo emulsifier (T).

The system (S) comprises: a jacket (1), which is arranged in such a way as to at least partially envelop a vessel (D) of the mixer (T) or of the turbo emulsifier (T) in which substances to be mixed and emulsified are placed in order to obtain a final product, the jacket (1) is configured and predisposed to receive internally thereof, and enable the circulation, of a fluid, and comprises an inlet opening (11), for inlet, into the jacket, of a fluid, and an outlet opening (12), for outlet, from the jacket (1), of a fluid; and a thermoregulation unit (UT) responsible for carrying out, managing and controlling the temperature variations, whether cooling and/or heating, of the vessel (D).

The thermoregulation unit (UT) comprises, in the various possible embodiments thereof (see for example figures from 1 to 6): an electronic control unit (2); a temperature sensor (3), which is arranged and configured to detect the temperature internally of the vessel (D), and is interfaced with the electronic control unit (2) in such a way as to send to the electronic control unit (2) signals relative to temperature values detected internally of the vessel (D); a closed hydraulic circuit (4) constituted by a single conduit having a first end of conduit which is connected to the inlet opening (11) of the jacket (1) and a second end of conduit which is connected to the outlet opening (12) of the jacket (1); a heat transfer fluid internal of the hydraulic circuit (4) and of the jacket (1); circulation means (5, R) of fluid, interfaced with the electronic control unit (2) and configured for the circulation of the heat transfer fluid internally of the hydraulic circuit (4) and internally of the jacket (1), and for the regulating of the flow rate of the heat transfer fluid internally of the hydraulic circuit (4) and therefore internally of the jacket (1).

By closed hydraulic circuit is meant a hydraulic circuit which directly closes on the jacket (1) of the vessel of the mixer (T) or of the turbo emulsifier (T), with or without an expansion tank, i.e. a hydraulic circuit that, as mentioned in the foregoing, is constituted by a single conduit of circulation of the heat transfer fluid having a first end of conduit which is connected to the inlet opening of the jacket and a second end of conduit which is connected to the outlet opening of the jacket.

The thermoregulation unit (UT) also comprises: heating means (H), which are interfaced with the electronic control unit (2), which are configured and arranged with respect to the hydraulic circuit (4) in such a way, when activated by the electronic control unit (2), as to heat the heat transfer fluid circulating internally of the hydraulic circuit (4); cooling means (C), which are interfaced with the electronic control unit (2), which are configured and arranged with respect to the hydraulic circuit (4) in such a way, when activated by the electronic control unit (2), as to cool the heat transfer fluid circulating internally of the hydraulic circuit (4).

In particular, the heating means (H) and the cooling means (C) are arranged in series with respect to the single conduit of circulation of the closed circuit.

In this way, the heat transfer fluid can acquire from the heating means (H) and/or from the cooling means (C), when activated by relative commands received from the electronic control unit (2), heat energy for heating and/or for cooling, and, when transiting internally of the jacket (1), and can generate a heat exchange with the vessel (D) for raising or lowering the temperature internal thereof.

The electronic control unit (2) of the thermoregulation unit is configured to: activate and regulate both the functioning of the heating means (H) and/or the functioning of the cooling means (C) and/or of the circulation means (5, R) of fluid; i.e. the electronic control unit (2) is configured to be able to activate and regulate the functioning of only the heating means, or of only the cooling means, or of only the circulation means (5, R) of fluid, or any combination thereof.

The electronic control unit (2) is further configured to be programmable (for example by entering data via a relative display, or a terminal, by a user) to set at least a temperature value (T1, T2) to be reached in a respective prefixed time interval (t1, t1*, t2, t2*) internally of the vessel (D).

The electronic control unit (2) is further configured, and programmed, as a function of the signals received from the temperature sensor (3) indicating the effective temperature present internally of the vessel (D) to command and regulate indifferently the functioning of the heating means (H) and/or of the cooling means (C), in order to vary the quantity of heat energy transmitted to the heat transfer fluid, and/or to intervene on the circulation means (5, R) of fluid in order to regulate and vary the flow rate of the heat transfer fluid circulating internally of the hydraulic circuit (4), and therefore internally of the jacket (1), in such a way as to control, in real-time, the effective heat exchange between the heat transfer fluid circulating internally of the jacket (1) and the vessel (D) of the turbo emulsifier (T), so that the temperature internally of the vessel (D) reaches the first set cooling temperature value (T1 , T2) in the prefixed time interval (t1 ,t1*, t2, t2*). For this purpose, the electronic control unit is configured to be able to intervene only on the heating means, or only on the cooling means, or only on the fluid circulation means, as well as on or any combination thereof.

Therefore, the system (S) of the invention, owing to the presence of the hydraulic circuit (4), constituted by a single conduit of circulation of the heat transfer fluid which closes by means of the respective two ends of conduit directly in the jacket (1), and of the heat transfer fluid which is circulated in the hydraulic circuit (4), and therefore internally of the jacket (1), is able to carry, via the heat transfer fluid, heat energy for heating and/or for cooling directly into the jacket (1), and further is able to regulate and control the heat exchange that is generated during the passage of the heat transfer fluid internally of the jacket (1), between the jacket (1) and the vessel (D).

In this way, the user can manage, control and regulate variations of temperature to be reach internally of the vessel in a respective prefixed time interval.

The control and regulating of the variations of temperature can preferably regard only the cooling step, or both the cooling step and/or the heating step, or possibly also only the heating step.

For example, with reference to figure 13, the user can set a first cooling temperature value (T2) to be reached in a respective first time interval (t2), obtaining a cooling curve denoted by reference (V1), or set, for the same cooling temperature value (T2), a respective time interval (t2*) that is longer, in this case obtaining the cooling curve in an unbroken line denoted by reference (V2).

In the same way, again with reference to figure 13, the user can set a second heating temperature value (T1) to be reached in a respective second time interval (t1), obtaining a heating curve denoted by reference (W1), or set, for the same heating temperature value (T1), a respective time interval (t1*) that is longer, in this case obtaining the heating curve indicated in an unbroken line denoted by reference (W2).

The two above-described possibilities can be actuated one irrespective of the other, or both at the same time.

The possibility of control and management of the varying of the temperature internally of the vessel, for example the cooling temperature and/or heating temperature, is made possible by the ability of the electronic control unit to intervene, in real-time and on the basis of signals received from the temperature sensor indicating the effective temperature present internally of the vessel of the mixer or the turbo emulsifier, to activate/regulate/vary the functioning of the heating means, and/or of the cooling means, as well as the circulation means of the flow in order to regulate the flow of the heat transfer fluid internally of the hydraulic circuit.

Consequently, the system (S) of the invention enables obtaining variations of temperature internally of the vessel of a mixer or of a turbo emulsifier while unlinked from the systems present at the final user’s facility.

Further, the system (S) of the invention, having already its own closed hydraulic circuit, constituted by single conduit which closes directly with the two respective ends of conduit on the jacket, for the circulation of heat transfer fluid internally of the jacket, avoids the drawback of having to design and dimension, time by time, the jacket according to the type of systems present at the final user’s facility.

In a possible preferred embodiment of configuration of the thermoregulation unit (UT) of the system of the invention, the electronic control unit (2) is configured to be programmable (see again for example figure 13) with a first series of data (e, f, g, h), indicating a first series of cooling temperature values to be reached in a respective first series of prefixed time intervals during a cooling step of the vessel (D) and/or with a second series of data (a, b, c, d) indicating a second series of heating temperature values to be reached in a respective second series of time intervals during a heating step of the vessel (D).

The electronic control unit (2), therefore, is also configured, according to the signals received from the temperature sensor (3) indicating the effective temperature present internally of the vessel (D), to command and regulate indifferently the functioning of the heating means (H) and/or of the cooling means (C), in order to vary the quantity of heat energy transmitted to the heat transfer fluid, and/or to intervene on the circulation means (5, R) of fluid in order to regulate and vary the flow rate of the heat transfer fluid circulating internally of the hydraulic circuit (4), and thus of the jacket (1), so as to manage and control, in real-time, the effective heat exchange between the heat transfer fluid circulating internally of the jacket (1) and the vessel (D) of the turbo emulsifier so that, during the cooling step and/or during the heating step, the temperature internally of the vessel (D) reaches the temperature values of the first series of cooling temperature values in the time intervals of the first series of prefixed time intervals, and reaches the temperature values of the second series of heating temperature values in the time intervals of the second prefixed series of time intervals.

Therefore, in this case, again with reference to figure 13, it is possible to obtain the cooling curve (V2) denoted with a broken line and the heating curve (W2) denoted with a broken line.

In the embodiments illustrated in the figures of the drawings, the cooling means (C) can comprise a plate heat exchanger (6) and a respective service circuit (60), passing through the plate heat exchanger (6).

The service circuit (60) of the plate heat exchanger (6) comprises an inlet branch (61) and an outlet branch (62) which are configured to be connected to a supply source of a cooling fluid (for example a refrigerating fluid coming from a refrigerating unit, or cold water of a few Celsius degrees, coming from a chiller) so that a cooling fluid can circulate in the service circuit (60) and circulate in the plate heat exchanger (6) for the cooling of the heat transfer fluid circulating in the hydraulic circuit (4).

The cooling means (C) comprise regulating means (63) of the cooling fluid flow internally of the service circuit (60), interfaced with and commandable by the electronic control unit (2), for interrupting and/or regulating the cooling fluid flow rate that crosses the plate heat exchanger (6).

For example, in the possible embodiments, illustrated in figures 1, 2 and 3, the regulating means (63) of the cooling fluid flow internally of the service circuit (60) of the plate heat exchanger (6) comprise a valve (64) which is arranged along the inlet branch (61) of the service circuit (60) and commandable by the electronic control unit (2).

The valve (64) can be commandable to close entirely, and thus inhibit inlet to the service circuit (60) of the plate heat exchanger (6) of the cooling fluid, or the valve can be commandable to open entirely or partially open for regulating the cooling fluid flow rate internally of the service circuit (60) and thus to regulate the quantity of heat energy for cooling to be transferred to the heat transfer fluid internally of the hydraulic circuit (4).

According to other possible embodiments, illustrated in figures 4, 5 and 6, the regulating means (63) of the cooling fluid flow internally of the service circuit (60) of the plate heat exchanger (6) comprise a by-pass branch (65), which is arranged between the inlet branch (61) and the outlet branch (62), so as to connect the inlet branch (61) with the outlet branch (62) and by-pass the plate heat exchanger (6), and a three-way valve (66), commandable by the electronic control unit (2), which is arranged in the connection point between the by-pass branch (65) and the outlet branch (62).

The three-way valve (66) can thus be commandable: to circulate all the cooling fluid through the by-pass branch (65), or to circulate all the cooling fluid through the whole service circuit (60) of the plate heat exchanger (6), or to circulate a first part of the cooling fluid flow internally of the service circuit (60) and a second part of the cooling fluid flow through the by-pass branch (65).

This solution enables maintaining the supply source of the cooling fluid active without causing overpressures.

The heating means (H) preferably comprise a resistance heating unit (H1) and/or a steam heat exchanger (H2) with a respective service circuit (70), passing through the steam heat exchanger (H2).

In the embodiments illustrated in figures 1 and 4, the heating means (H) only comprise a resistance heating unit (H1). In the embodiments illustrated in figures 2 and 5, the heating means (H) only comprise a steam heat exchanger (H2).

In the embodiments illustrated in figures 3 and 6, the heating means (H) can comprise both a resistance heating unit (H1) and a steam heat exchanger (H2).

Other embodiments can also be included for the heating means, such as for example microwaves, but still remaining within the ambit of the invention.

The resistance heating unit (H1) comprises one or more series of resistance batteries which are interfaced with the electronic control unit (2), a power supply for supplying the resistance batteries (not illustrated in the figures), and a regulating means (V) of the power supply, commandable by the electronic control unit (2), for regulating the power supply to the resistances and therefore the quantity of heat transferable to the heat transfer fluid circulating in the hydraulic circuit (4).

The service circuit (70) of the steam heat exchanger (H2) comprises a respective inlet branch (71) and a respective outlet branch (72) configured in such a way as to be connected to a supply source of steam so that a steam flow can circulate in the service circuit (70) and therefore circulate in the steam heat exchanger (H2) for heating the heat transfer fluid circulating in the hydraulic circuit (4).

In the case of presence of a steam heat exchanger (H2), regulating means (73) of the steam flow internally of the service circuit (70) of the steam heat exchanger (H2) are provided, interfaced with and commandable by the electronic control unit (2), for regulating the flow rate of the steam flow that crosses the steam heat exchanger (H2).

For example, the regulating means (73) of the steam flow internally of the service circuit (70) of the steam heat exchanger (H2) comprise a valve (74), commandable by the electronic control unit (2), which is arranged along the inlet branch (71) of the service circuit (70) (see for example figure 2 and figure 3). The valve (74) can be commandable to close entirely, and thus inhibit inlet of the steam to the service circuit (70) of the steam heat exchanger (H2), or can be commandable to open entirely or to partially open to regulate the flow rate of the steam flow internally of the service circuit (70) and thus regulate the quantity of heating heat energy to be transferred to the heat transfer fluid internally of the hydraulic circuit.

Alternatively, the regulating means (73) of the steam flow internally of the service circuit (70) of the steam heat exchanger (H2) comprise a by-pass branch (75) arranged between the inlet branch (71) and the outlet branch (72) of the service circuit (70) of the steam heat exchanger (H2), for connecting the inlet branch (71) with the outlet branch (72) and to by-pass the steam heat exchanger (H2), and a three-way valve (76) arranged in the connection point between the by-pass branch (75) and the outlet branch (72).

The three-way valve (76) can thus be commandable: to circulate all the steam flow through the by-pass branch (75), or to circulate all the steam flow through the whole service circuit (70) of the steam heat exchanger (H2), or to circulate a first part of the steam flow internally of the service circuit (75) and a second part of the steam flow through the by-pass branch (75).

This solution enables maintaining the supply source of the steam active without causing overpressures.

In the possible embodiments, illustrated in the figures, the fluid circulation means (5, R) comprise a pump (5) and flow regulating means (R) for regulating the flow rate of the heat transfer fluid circulating internally of the single conduit of the hydraulic circuit (4) and therefore internally of the jacket (1).

In the preferred embodiments of figures 1 , 2, 3, in order to regulate the flow rate of the heat transfer fluid circulating internally of the single conduit of the hydraulic circuit (4) and therefore internally of the jacket (1), the flow regulating means (R) can comprise a regulating valve (15) arranged along the hydraulic circuit (4) downstream of the pump (5) and upstream of the inlet opening (11) of the jacket (1), and interfaced and commandable by the electronic control unit (2).

The regulating valve (15) can be commandable to open entirely or to close entirely, or to partially open, for regulating the flow rate of the heat transfer fluid internally of the jacket (1), and thus also regulate the heat exchange with the vessel (D) of the turbo emulsifier (T).

In the possible embodiments of figures 4, 5, 6, the flow regulating means (R) for regulating the flow rate of the heat transfer fluid circulating internally of the hydraulic circuit (4) and therefore internally of the jacket (1), can comprise a by-pass branch (16) of the hydraulic circuit (4), between the inlet opening (11) and the outlet opening (12) of the jacket and upstream of the pump (5), and a regulating valve (17) arranged along the by-pass branch (16), interfaced with and commandable by the electronic control unit (2).

The regulating valve (17) can be commandable by the electronic control unit (2) in such a way that all the flow of the heat transfer fluid circulates in the hydraulic circuit (4) up to the jacket (11), or a part of the flow also transits through the by-pass branch (16).

The system (S) of the invention is configured and predisposed in such a way that the electronic control unit (2) can consist of or is connectable to a control and command unit (8) present in a mixer (T) or in a turbo emulsifier (T) in order to interact and communicate therewith in order to manage and control the heating and cooling steps of the vessel (D) of the mixer (T) or of the turbo emulsifier (T) in relation to the working and processing steps of the substances to be mixed and emulsified internally thereof.

With reference to figures from 7A a 12B, and to figure 13, the following is a description of possible modes of functioning of the system (S) of the invention, in the various possible preferred embodiments of figures from 1 to 6, for management and control of variations of temperature internally of a vessel (D) of a mixer (T) or of a turbo emulsifier, in particular with reference to a heating or a cooling of the vessel (D).

Figure 7A illustrates possible modes for carrying out a heating step of the vessel (D) of the turbo emulsifier (T) according to the first embodiment of the system of the invention as in figure 1.

A first heating mode can include: closing the valve (64) of the regulating means (63) of the service circuit (60) of the plate heat exchanger (6) of the cooling means (C) in such a way as to prevent inlet of the cooling fluid into the service circuit (60); activating the resistance battery (H1) of the heating means (H) (ON symbol) at the maximum power thereof; regulating the valve (15) of the regulating means (R) of the circulation of heat transfer fluid in the hydraulic circuit (4) at the maximum opening thereof; regulating the pump (5) and the normal functioning rate thereof.

(3) indicating the effective temperature present internally of the vessel of the turbo emulsifier the user can intervene indifferently: on the three-way valve (66) of the regulating means (63) of the service circuit (60) of the plate heat exchanger (6) of the cooling means (C) (arrow in a broken line and denoted by e1 in figure 11 B) to enable passage of a part or all of the cooling fluid flow, through the by-pass branch (65), partially or totally bypassing the plate heat exchanger (6) (arrow in a broken line in figure 11 B); on the three-way valve (76) of the regulating means (73) of the service circuit (70) of the steam heat exchanger (H2) (arrow in a broken line and denoted by e2 in figure 11 B) to enable passage of a part or all of the steam flow through the steam heat exchanger (H2) (arrow in a broken line in figure 11 B) and thus for varying and regulating the heating heat energy to be transmitted to the heat transfer fluid circulating in the hydraulic circuit; on the valve (17) of the regulating means (R) of the flow of heat transfer fluid circulating in the hydraulic circuit to enable passage of a part or all of the flow of the heat transfer fluid, through the by-pass branch (16), partially or totally by-passing the jacket (1) (arrow in a broken line and denoted by e3 in figure 11B); on the pump (5), to vary the flow rate thereof, and thus vary and regulate the flow rate of the heat transfer fluid which will circulate in the jacket (1) (arrow in a broken line and denoted by e4 in figure 11B).

The above-described regulating modes can be carried out singly and independently of one another, or in any combination with one another, both contemporaneously and in succession to one another.

Figure 12A illustrates possible modes for carrying out a heating step of the vessel (D) of the turbo emulsifier (T) according to the sixth embodiment of the system of the invention as in figure 6.

A first heating mode can include: commanding the three-way valve (66) of the regulating means (63) of the service circuit (60) of the plate heat exchanger (6) of the cooling means (C) in such a way that all cooling fluid flow transits in the by-pass branch (65) (arrows in an unbroken line in figure 12A), by-passing the service circuit (60); activating the resistance batteries (H1) of the heating means (H) (ON symbol) at the maximum power thereof; commanding the three-way valve (76) of the regulating means (73) of the service circuit (70) of the steam heat exchanger (H2) of the heating means (H) in such a way that all the steam flow can cross the steam heat exchanger (H2) (ON symbol in figure 7B); regulating the valve (17) of the regulating means (R) of the circulation of heat transfer fluid in the hydraulic circuit (4) in such a way that all the flow of the heat transfer fluid circulates in the hydraulic circuit up to the jacket (1); regulating the pump (5) and the normal functioning rate thereof.

In this way it is possible to obtain a maximum heating curve, i.e. a heating curve which includes reaching the value of the heating temperature (T1) set for processing the substances internally of the vessel (D) of the turbo emulsifier (T) in the shortest possible time, for example in the time interval (t1) (see figure 13).

The maximum heating curve is for example illustrated figure 13 in an unbroken line and with reference (W1).

In a case in which the user of the turbo emulsifier, for working needs, desired instead to reach the heating temperature value (T1) set for the processing of the substance internally of the vessel of the turbo emulsifier over a longer time (for example t1*, figure 13), or to reach determined heating temperature values in respective time intervals (points a, b, c, d in figure 13, broken line (W2)), the user will be able to program the electronic control unit (2) so that as a function of the signals received from the temperature sensor (3) indicating the effective temperature present internally of the vessel of the turbo emulsifier the user can intervene indifferently: on the regulating means (V) of the power supply of the resistance batteries (H1) (arrow in a broken line and denoted by f1 in figure 12A) to regulate and vary the functioning power of the resistance batteries, for regulating and varying the heat energy for heating to be transmitted to the heat transfer fluid circulating in the hydraulic circuit; on the three-way valve (76) of the regulating means (73) of the service circuit (70) of the steam heat exchanger (H2) (arrow in a broken line and denoted by f2 in figure 12A) to enable passage of a part or all of the steam flow through the by-pass branch (75), partially or totally by-passing the steam heat exchanger (H2) (arrow in a broken line in figure 12A) and thus for varying and regulating the heating heat energy to be transmitted to the heat transfer fluid circulating in the hydraulic circuit; on the three-way valve (66) of the regulating means (63) of the service circuit (60) of the plate heat exchanger (6) of the cooling means (C) (arrow in a broken line and denoted by f3 in figure 12A) to enable passage, by regulating al part of the flow rate, or all of the cooling fluid flow, through the plate heat exchanger (6) (arrow in a broken line in figure 12A) to cool the heat transfer fluid circulating in the hydraulic circuit; on the valve (17) of the regulating means (R) of the flow of heat transfer fluid circulating in the hydraulic circuit to enable passage of a part or all of the flow of the heat transfer fluid, through the by-pass branch (16), partially or totally by-passing the jacket (1) (arrow in a broken line and denoted by f4 in figure 12A); on the pump (5), to vary the flow rate thereof, and thus vary and regulate the flow rate of the heat transfer fluid which will circulate in the jacket (1) (arrow in a broken line and denoted by f5 in figure 12A).

The above-described regulating modes can be carried out singly and independently of one another, or in any combination with one another, both contemporaneously and in succession to one another.

Figure 12B illustrates possible modes for carrying out a cooling step of the vessel (D) of the turbo emulsifier (T) according to the sixth embodiment of the system of the invention as in figure 6.

A first cooling mode can include: keeping the resistance batteries (H1) of the heating means (H) switched off; commanding the three-way valve (76) of the regulating means (73) of the service circuit (70) of the steam heat exchanger (H2) of the heating means (H) in such a way that all the steam flow passes through the by-pass branch (75) (unbroken arrow), by-passing the steam heat exchanger (H2); commanding the three-way valve (66) of the regulating means (63) of the service circuit (60) of the plate heat exchanger (6) of the cooling means (C) in such a way that the cooling fluid can transit at its maximum flow rate through the plate heat exchanger (6) (ON symbol in figure 12B); regulating the valve (17) of the regulating means (R) of the circulation of heat transfer fluid in the hydraulic circuit (4) in such a way that all the flow of the heat transfer fluid circulates in the hydraulic circuit up to the jacket (1); regulating the pump (5) and the normal functioning rate thereof.

In this way it is possible to obtain a maximum cooling curve, i.e. a cooling curve which includes reaching the value of the cooling temperature (T2) set for extracting the final product from the vessel (D) of the turbo emulsifier (T) in the shortest possible time, for example in the time interval (t2) (see figure 13).

The maximum cooling curve is for example illustrated figure 13 in an unbroken line and with reference (V1).

In a case in which the user of the turbo emulsifier, for processing needs, desired instead to reach the cooling temperature value (T2) set for the extracting of the final product from the vessel of the turbo emulsifier over a longer time (for example t2*, figure 13), or to reach determined cooling temperature values in respective time intervals (points e, f, g, h in figure 13, broken line (V2)), the user will be able to program the electronic control unit

(2) so that as a function of the signals received from the temperature sensor

(3) indicating the effective temperature present internally of the vessel of the turbo emulsifier the user can intervene indifferently: on the three-way valve (66) of the regulating means (63) of the service circuit (60) of the plate heat exchanger (6) of the cooling means (C) (arrow in a broken line and denoted by hi in figure 12B) to enable passage of a part or all of the cooling fluid flow, through the by-pass branch (65), partially or totally bypassing the plate heat exchanger (6) (arrow in a broken line in figure 12B); on the regulating means (V) of the power supply of the resistance batteries (H1) (arrow in a broken line and denoted by h2 in figure 12B) for activating the resistance batteries (H1), for regulating and varying the functioning power, for regulating the heating heat energy to be transmitted to the heat transfer fluid circulating in the hydraulic circuit; on the three-way valve (76) of the regulating means (73) of the service circuit (70) of the steam heat exchanger (H2) (arrow in a broken line and denoted by h3 in figure 12B) to enable passage of a part or all of the steam flow through the steam heat exchanger (H2) (arrow in a broken line in figure 12B) and thus for varying and regulating the heating heat energy to be transmitted to the heat transfer fluid circulating in the hydraulic circuit; on the valve (17) of the regulating means (R) of the flow of heat transfer fluid circulating in the hydraulic circuit to enable passage of a part or all of the flow of the heat transfer fluid, through the by-pass branch (16), partially or totally by-passing the jacket (1) (arrow in a broken line and denoted by h4 in figure 12B); on the pump (5), to vary the flow rate thereof, and thus vary and regulate the flow rate of the heat transfer fluid which will circulate in the jacket (1) (arrow in a broken line and denoted by h5 in figure 12B).

The above-described regulating modes can be carried out singly and independently of one another, or in any combination with one another, both contemporaneously and in succession to one another.

The electronic control unit (2) of the system (S) of the invention can also be programmed to carry out the activation and regulating of the heating means, of the cooling means, of the pump, and of the regulating means of the circulation of the heat transfer fluid in the hydraulic circuit and internally of the jacket, even with different modalities with respect to the ones described in the foregoing.

The system (S) of the invention can also include the use of heating means and cooling means different from the ones described for carrying out the heating and/or cooling of the heat transfer fluid responsible for the transfer of heating/cooling heat energy to the vessel of the turbo emulsifier.
