TECHNICAL FIELD

The various aspects and variations thereof relate to the field of process analysis and control for a beverage manufacturing plant and a brewery for beer in particular.

BACKGROUND

Manufacturing of beverages and brewing of beer in particular is a complex process, involving many different steps. The process is primarily a chemical and biological process of which the course as well as the result in determined by many factors at each step, each of which may influence an end result. By trial and error, conditions for brewing may be improved, but with many factors that may influence one and the same factor with only very small changes of values of each factor, using trial and error may not be a feasible way to arrive at improved process control parameters.

SUMMARY

It is preferred to provide for acquisition of process parameters values and for providing a relation between these process parameters and quality of an end product. Based on such relation, set point values for process control may be provided to arrive at an end product with improved quality and preferable optimal quality.

A first aspect provides, for executing in an a electronic process analysis device, a method of determining, for a first product quantity having undergone a first processing step as part of a manufacturing process, a relation between at least one of a set of process parameters of the first processing step and a set of ingredient parameters on one hand and at least one product component parameter on the other hand. The method comprises at least one of obtaining, from a process data acquisition control system, process data comprising at least one first process parameter value related to the first processing step of the first product quantity and obtaining, from the process data acquisition control system, ingredient data comprising at least one first ingredient parameter value related to an ingredient forming a basis for the first product quantity. So either the first process parameter value or the first ingredient parameter value is obtained - or both. The method further comprises identifying at least one product component potentially present in the first product quantity and obtaining at least one first product component parameter value for the first product quantity related to the first component. Based on the at least one of the first process parameter value and the first ingredient parameter value on one hand and the product component parameter value on the other hand, a relation score indicative of a relation between the at least one of the process parameter value and the ingredient parameter value on one hand and the product component parameter value on the other hand is determined.

Quality of a beverage may be determined largely by particular components present - or not - in the beverage and, if present, on the amount of components present in the beverage, either as a whole or in a unit volume or mass of the beverage. Presence of such components may relate to any process parameters, ingredients, other factors or a combination thereof and with the method according to the first aspect, such relation may be determined. And with information on such relations, process parameters and ingredient parameters may be tweaked for a subsequent batch with an aim to arrive at improved component parameter values, which may provide an improved quality of the beverage.

Second, a method as that of the first aspect may allow for improved process initialisation and ramp up as well as auto-calibration of beverage manufacturing lines and beverage manufacturing plants. Rather than characterising a new plant for a known process with machinery that may be different from that of earlier plants - either slightly different or very different - by means of obtaining dimensions of reactor vessels, calibrating sensors and simulations, information on appropriate process parameters may be obtained by running one or more pilot runs and applying the method of the first aspect.

A variation of the first aspect comprises at least one of obtaining, from a process data acquisition control system, process data comprising at least one first process parameter value related to the first processing step of a second product quantity and obtaining , from the process data acquisition control system, ingredient data comprising at least one first ingredient parameter value related to the ingredient forming a basis for the second product quantity. In this variation, the determining of the relation score between the at least one of the process parameter value and the ingredient parameter value on one hand and the product component parameter value on the other hand is also based on the at least one of the second process parameter value and the second ingredient parameter value.

With data from multiple batches, usually with different values for the applicable parameters, relations may be determined more accurately. With more data, analysis may be more fault tolerant. Furthermore, this may allow for determining whether relations between values are linear, quadratic, cubic, exponential, monotonic/non-monotonic, strong/weak, being correlated within particular boundaries or not, other or a combination thereof.

Another variation further comprises at least one of obtaining a multitude of process parameter values related to the first processing step of the first product quantity and obtaining a multitude of ingredient parameter values related to a multitude of ingredients forming a basis for the first product quantity and, based on the multitude of process parameter values and the multitude of ingredient parameter values on one hand and the product component parameter value on the other hand, determining a relation between each of the multitude of the process parameter values and each of the multitude of the ingredient parameter value on one hand and the product component parameter value on the other hand. Based on the outcome of the analysis, a pre-determined number of at least one of the multitude of process parameters and the multitude of ingredient parameters are selected that have relation scores indicating strongest relations with the product component parameter value.

This variation provides direct and compact feedback to a user of the system employing the first aspect. In this way, the user - for example a process control operator or process supervisor - can focus on the most relevant parameters to tinker with. Alternatively or additionally, no human being is involved and an electronic computing system controls the process based on the most relevant parameters. Optionally, one values of the most relevant parameters are set at or close to an optimum, other parameters may be selected for presentation to the user to allow tweaking of the values of the latter parameters.

In a further implementation, the manufacturing process comprises batch processing and the first product quantity comprises at least one batch. In batch processing, quantities of beverages are well separated from one another. This allows for convenient and practical analysis of relations between various parameters on a per-batch analysis.

In yet another implementation, at least one of the first process parameter value has a first process parameter timestamp associate therewith, indicative of a starting point of the first processing step; and the first ingredient parameter value has a first ingredient timestamp associated therewith indicative of a moment in time at which the first ingredient is added to the first product quantity.

Adding an ingredient at a specific moment during the process, changing temperature settings at a particular moment or an actual change of that temperature at a particular moment may be relevant to the end result. By taking into account timing data while registering data and when determining relations, the determining of the relations may be done in a more accurate way and the timing of particular process parameters may be provided at the output of the process.

In again a further implementation, the manufacturing process is a continuous process, further comprising obtaining a throughput time interval of the first processing step indicative of the first product quantity undergoing the first processing step.

Whereas mixing of a defined quantity of beverage with other quantities of beverage having undergone possibly other processing, a particular quantity of beverage may be identified and followed by monitoring flow rate through conduits and reactors. With such data, a time may be determined when the defined quantity enters a reactor or a particular processing step and when the defined quantity leaves the reactor or the particular processing step.

In yet another implementation, the first process parameter value is one of a control value and a measured value. A control value may be a set point for an actuator to be achieved or expected to be achieved by, for example, controlling the actuator with a particular pressure of a gas, a voltage, a current, other, or a combination thereof. The measured value may then be an actual value within a reactor or other vessel or conduit in which the beverage is provided.

Yet a further implementation further comprises obtaining an objective quality relation between objective quality score parameter data related to at least one product parameter; and determining, based on the quality relation and a value of the at least one product parameter, an objective quality score value the first quantity. As indicated above, quality of a beverage may be determined by components present, such as esters. Additionally or alternatively, quality may be determined by other features of the beverage, like viscosity, colour, bitterness, transparency, translucency, sweetness, acidity, sourness, other, or any combination of two or more of these features. Well noted, such properties may be determined by components present and quantities thereof, but physical properties like viscosity or firmness of foam may be more convenient to register.

Again another implementation comprises obtaining a first quality score value for the first quantity; obtaining a second quality score value for the second quantity and, based on the first quality score value, the second quality score value, at least one product component parameter value of the first quantity and at least one product component parameter value of the second quantity, a quality relation between the product component parameter and a quality score. This allows for obtaining more and possible improved data and accuracy on the relations.

A further implementation further comprises obtaining a first quality score value for the first quantity, obtaining a second quality score value for the second quantity and, based on the first quality score value, the second quality score value, at least one process parameter value of the first quantity and at least one process parameter value of the second quantity, a quality relation between the process parameter and a quality score. This allows for obtaining more and possible improved data and accuracy on the relations.

Another implementation further comprises obtaining a first quality score value for the first quantity, obtaining a second quality score value for the second quantity and, based on the first quality score value, the second quality score value, at least one ingredient parameter value of the first quantity and at least one ingredient parameter value of the second quantity, a quality relation between the ingredient parameter and a quality score. This allows for obtaining more and possible improved data and accuracy on the relations.

An electronic process analysis device for determining, for a first product quantity having undergone a first processing step as part of a manufacturing process, a relation between at least one of a set of process parameters of the first processing step and a set of ingredient parameters on one hand and at least one product component parameter on the other hand. The device comprises an input, an output and a processing unit. The input is arranged to perform at least one of obtaining, from a process data acquisition control system, process data comprising at least one first process parameter value related to the first processing step of the first product quantity and obtaining, from the process data acquisition control system, ingredient data comprising at least one first ingredient parameter value related to an ingredient forming a basis for the first product quantity; identifying at least one product component potentially present in the first product quantity; and obtaining at least one first product component parameter value for the first product quantity related to the first component. The processing unit is arranged to determine, based on the at least one of the first process parameter value and the first ingredient parameter value on one hand and the product component parameter value on the other hand, a relation score indicative of a relation between the at least one of the process parameter value and the ingredient parameter value on one hand and the product component parameter value. And the output is arranged to provide data on at least one of the relation or the relation score indicative of a relation.

Another aspect provides a computer program product comprising computer executable code arranged to cause a computer, when the executable code is loaded in a memory connected to an electronic processing unit comprised by the computer for programming the electronic processing unit, to execute the method according to the first aspect or any variation thereof or permutations thereof. A further aspect provides a non-transitory memory having stored therein or thereon such computer program product. BRIEF DESCRIPTION OF THE DRAWINGS

250 next step for intermediate product

The procedure starts in a terminator 202 and continues to step 204 in which a quantity of beverage to analyse is defined. The quantity to analyse may be a batch of the beverage, which relates to one and the very same beverage that undergoes a particular processing step by a particular piece of equipment - as a whole. Alternatively or additionally, a quantity of the beverage may be defined as a volume of a continuous or semi-continuous flow of beverage that flows through processing steps while undergoing processing.

A continuous flow quantity may be defined by monitoring flow - flow velocity as flow speed in distance per time unit, mass per time unit, volume per time unit, or a combination thereof - and a start time and an end time per monitoring point. The flow and the progress of central time may be used to determine when the defined quantity arrives at a next processing step - and leaves the next processing step. In the brewery, the identified quantity, with which the brewing process starts, may be a quantity of water.

In 206, the processing step is started for the defined quantity. If the processing is a batch process, the processing is started for the defined quantity. If the processing step is a continuous process, a first part of the identified quantity enters a processing vessel, a processing conduit, another processing entity or a combination thereof.

In step 208, one or more ingredients are added to the identified quantity. For example, malt may be added to the water. In step 210, the ingredients added are sensed by means of the first ingredient sensor module 152 and data is registered, for example in the memory 104. Each ingredient may be registered as a parameter. With the ingredient parameter, several values sensed or otherwise received, via automated or manual input, may be received and thus associated. The values may relate to quality, sugar content, type, other as specified above, other, or a combination thereof.

The associated value or values may be a numerical value - discrete, real, rational or complex - a Boolean value, an alphanumerical value, other, or a combination thereof. Furthermore, a timestamp may be associated with the ingredient parameter at the moment of acquisition of values. Alternatively or additionally, individual timestamps may be associated with individual parameters values. The timestamp may, together with throughput speed of matter through the system, be used to assign values of the parameter to a particular defined quantity, in particular in continuous processing.

In step 212, upon or after start of the applicable processing step, the first rudder 122 is started. In step 214, values of actuator parameters are obtained and registered, for example in the memory 104. Such parameter may be activation of the first rudder 122 and associated values may be a sensed rotational speed in revolutions per time unit like seconds or minutes, an angular speed, a torque, other, or combination thereof. The value may be an actual value, for example obtained by means of a sensor, or a set point, for example a value of an angular speed at which a processing unit controls the first rudder 122. Also other actuator parameters, for example of a heater, may be obtained. The associated value or values may be a numerical value - discrete, real, rational or complex - a Boolean value, an alphanumerical value, other, or a combination thereof. The Boolean value may for example indicate whether a particular valve is open or closed and an alphanumerical value may relate to a status message or an error message from a machine.

A timestamp may be associated with the actuator parameter at the moment of acquisition of values. Alternatively or additionally, individual timestamps may be associated with individual parameters values. The timestamp may, together with throughput speed of matter through the system, be used to assign values of the parameter to a particular defined quantity, in particular in continuous processing. The values may be registered at a moment a value changes or changes with more than a predetermined threshold. Alternatively or additionally, the values may be obtained at periodic intervals or continuously.

In step 216, process parameters are sensed, for example by means of the first process sensor module 156. In step 218, values obtained through the sensing of process parameters are registered, for example in the memory 104. A process parameter may be temperature of wort, transparency, conductivity or any other value or combination thereof as discussed above. A process parameter may also be an external parameter, like temperature, humidity, other or a combination thereof in a production hall, outside the production hall, in the open air, other, or a combination thereof.

A timestamp may be associated with the process parameter at the moment of acquisition of values. Alternatively or additionally, individual timestamps may be associated with individual parameters values. The timestamp may, together with throughput speed of matter through the system, be used to assign values of the parameter to a particular defined quantity, in particular in continuous processing. The values may be registered at a moment a value changes or changes with more than a pre- determined threshold. Alternatively or additionally, the values may be obtained at periodic intervals or continuously.

In step 220, it is verified whether the identified quantity has been processed by means of the applicable processing step. If the processing step is a batch process, the processing step may end as an end point has been reached. Such endpoint may be defined as a time interval having lapsed, a temperature value having been reached, another value of a registered value or one or more particular parameters having been reached, other, or a combination thereof. If the processing step is a continuous process the processing step for the identified quantity may be defined as having ended by the full defined quantity has left the applicable reactor in which the processing step takes place or has taken place.

If the processing step has not ended, yet, the process branches back to step 208 to add additional ingredients - or not - and to obtain and register further values of the various parameters. If the processing step has ended as discussed above, the procedure continues to step 222. In step 222, it is checked whether the full process has ended for the defined quantity or not. If the full process has not ended, the procedure branches back to step 206 for a subsequent processing step, via step 250 in which the next processing step is defined for the defined quantity.

If the full process has ended, the procedure continues to step 224, in which the end product of the full process is analysed in step 224. Such analysis may be physical, chemical, biological, other, or a combination thereof. A physical analysis relates to determining physical parameters of the end product, like transparency, colour, conductivity, foam firmness, other, or a combination thereof. A chemical analysis may relate to determining acidity, sugar content, content of particular substances or classes of substances, like esters, acids, other, or a combination thereof, carbon dioxide content, other or a combination thereof. A biological analysis may relate to determining presence of an amount of yeast in general, a particular yeast, other or a combination thereof. Preferably, the composition of the end product is determined, i.e. it is determined what amounts of particular components - substances - are in a unit volume or unit mass of the end product. The result may be stored in the memory 104 in step 226.

In step 230, the registered values of the various parameters are analysed and optionally processed. Such analysis may relate to detection of outliers, comparing to threshold values or threshold bands or interval, other, or a combination thereof. Processing may relate to removing outliers, determining derivative or integral values over time, other values or a combination thereof, steps in values over time, as function over values of another parameter, other, or a combination thereof. Such analysis and processing may yield additional values of analysed parameters or other parameters.

In step 228 is checked whether all identified quantities have been processed and the parameter values of the identified have been obtained and registered. If this is not the case, the procedure branches back to step 204 or, if further quantities have been defined, back to step 206. If all data to be analysed has been obtained from the identified quantities to be assessed, the procedure continues to step 232.

In step 232, quality parameters may be obtained for each quantity. Such quality parameters may be objective parameters, which may relate to physical, chemical or biological parameters, like quantities of particular matter in a sample from which the objective parameters are taken. In this sense 'objective' means that a value of the parameter may be acquired by measuring, counting and the like the value of a mass, time, a volume, conductivity, temperature and the like, as opposite to 'subjective', which is related to human perception.

If the firmness of the foam is sufficient, i.e. it holds a particular volume for more than a pre- determined amount of time, the parameter has a first Boolean value and if not, the parameter has a second Boolean value. In the same way, acidity and presence of particular components and amounts thereof per unit or levels of the amount relative to a threshold may constitute objective quality parameters. Instead of a Boolean value, numerical values may be used, for example on a scale from 0 to 9 or from 1 to 10.

Values of relative quality parameters or subjective quality parameters may for example be obtained through test persons, by tasting the end product, smelling the end product or otherwise evaluate the end product using their senses.

Step 232 may also be positioned before step 230, but if beverage matter from all process steps is assess for quality and for subjective quality in particular, once all quantities are available, comparing qualities may be more feasible.

In subsequent steps, relations between various parameters are assess based on values of the parameters. As discussed, multiple values may be associated with a parameters, indicating values of sub-parameters of particular parameters. Such relations may be determined by calculating for example correlation of values of parameters and sub-parameters. The values of sub-parameters may relate to the same parameter or other parameters. The relations between parameters may be determined within one defined quantity - intra-batch - or over multiple defined quantities - inter-batch.

In addition to calculating correlations, also other algorithms may be used for determining relations between parameters and, additionally or alternatively, neural networks or other machine learning algorithms may be employed to determine relationships between the various parameters and parameter sets on the input side and input sides, based on various values of the parameters. In yet another implementation, additionally or alternatively, least square methods may be used to fit parameter relations to a curve, which may be a linear, quadratic, cubic, exponential curve, another curve, or a combination thereof. More in particular, in step 234, relations between component parameters are related to parameters obtained during the process. The latter parameters may be process parameters, ingredient parameters, other, or a combination thereof. In step 236, relations between component parameters and parameters of which values are obtained during the process are determined. In step 238, relations between quality parameters - objective, subjective, or both - and component parameters are determined. In step 240, relations between component parameters and actuator parameters are determined, also further relations between parameters of which values are obtained may be assessed and determined.

Based on the relations determined and how strong those relations are - for example, a correlation of 0 is a very weak relation and a correlation of 1 or -1 or close to either one of these values is a strong relation -, parameters of which values obtained having the strongest relation to quality parameters are obtained. Such parameters may be the actuator parameters, the process parameters, the ingredient parameters, other, or a combination thereof.

In step 246, the result of the processing - relations, strength of relations, most relevant relations, relations most relevant to quality, either objective, subjective or both, statistical values, other, or a combination thereof - are provided to a user or another system for processing of data. As such, optimal values of ingredient parameters, actuator parameters, process parameters, other parameters or a combination thereof may be determined and provided to a user or a control device. The one or more parameters may be used to automatically optimise the machine setting. Subsequently, the process ends in step 246.

The process may be implemented as an iterative process that, by means of the iterations, may be fine-tuned and optimised by executing the process as described above to further improve and optimise the process and process parameter, either automatically or manually. For the optimisation, known or new algorithms or other technologies may be used, including, but not limited to least square methods, regression, interpolation, extrapolation, use of trained neural networks or other artificial intelligence used for machine learning, other, or a combination of two or more of these technologies.

The process thus far discussed is a brewing process. As discussed above, the mashing, cooking and cooling processes have been discussed in detail and the procedure of flowchart 200 and variations thereof may be applied to these processes. In the same procedure of flowchart 200 and variations thereof may be applied to the fermentation, clearing, carbonisation, filtering and other process steps of the brewing process.

Additionally or alternatively, the procedure and variations thereof may be applied to treatment of waste water, cleaning of the brewery equipment and a bottling process for filling bottles, kegs and cans.

In summary, the above relates to the point that quality of a natural product, like beer, bread, wine and the like, is determined by many parameters. Process parameters that may be changed or not, external parameters and parameters of ingredients. With complex processes and many process steps, it is very difficult to relate parameters to quality - if possible at all. Data on process control, values of product and process related parameters and values that may be interpreted as indicative of quality, substances found in the product - either final or intermediate - and quantities thereof, other parameters or combinations thereof. Between values obtained for the parameters, relations may be determined that may be used for process optimisation. This may be executed for one or more process steps and for one or more parameters in the process and one or more quality parameters.
