Until this day. there are no units for the dehydration (drying up) of loose products which are self-serviced (to fill, to empty and to lay flat the product in order to achieve its better dehydration) in order to compare them with our unit.

This invention reveals a unit for the dehydration (drying up) of loose products which due to the existence of a line of conveyor belts (with perforated floor surfaces wherever it is required) has the possibility to fill automatically, uniformity and in different desired heights the storage space of the products and to empty it automatically, furthermore, thanks to the presence of the perforated floor surface, the fan heater, the brunch-line tubes with a damper and the product-air space separation we achieve a correct circulation of the air from down to up or alternatively from up to down. in suitable quantity and quality, achieving thus, the required dehydration (drying up).

Referring to the loose products dehydration (drying up), this consists of : From the storage space-1-which is being supplied via an initial conveyor belt-2-with the product to be dehydrated (dried up) (grass-cereals-vegetables-aromatic plants cut or not into pieces-fruits-fertilizers-manure-and other loose products)- 3-. In continuation, through an upper horizontal conveyor belt (with perforated floor surface),-4-which moves vertically (that is raises and lowers) in an horizontal position achieving an homogenous distribution and the complete filling of the storage space at any level.

With the same conveyor belt takes place the exit of the ready product, by opening the lower part of door-5-dropping the ready product-3-on the external final bel-6-. There is a possibility for the construction of two variants of the unit, as regards the loading and unloading procedure. More precisely, in the first presentation there is a second floor conveyor belt (with a perforated floor surface) which carries the ready product to the exit, where, instead of the door-5-there is a belt door-5a- which aims at assisting the exit of the product, sometimes cutting

it into pieces and some other times after it raises, allows the exit of the product in massive form.

In the second, there are one or more conveyor belts (with a perforated floor surface). Indicatively, we have here the presentation of two additional ones the-4a-4b-among which, moves the product to be dehydrated (dried up) and finally when it is ready, it falls on the floor belt-7-which conveys it to the exit. where there is a special door for the air-product separation in order to deliver it for standardization.

The floor-8-is perforated either partly or totally according to the desired result.

Under the floor in fixed intervals. always according to the dehydration needs there are dampers-9-the same as the upper part-9a-9b-which aim at disturbing the air originating from the centra!tubes-10-10a-. The movement of the air takes place through a branch-line which has three dampers-9c-9d- 9e-. which direct the air or releases it to the environment.

As regards the process of the air supply, there is the possibility for the construction of variants of the unit, and more precisely : In one variant after being heated by the fan heater-12-. the dehydration (drying up) air, is conducted to the product through the flow tube-10-and the damper-9- (under the perforated floor) and the lateral product and air space separation- 22-and exits from the tube through the external door-23-or through the upper part of door-5-.

In one variant after being heated by the fan heater, the dehydration (drying up) air, is conducted to the product, through the flow tube-10-and the damper-24-25-and exits through the tube with external the damper-24-or through the upper part of door-5-.

The branch-line-11-is connected to the fan heater-12- which produces air of different quantities and qualities, according to the needs of dehydration (drying up). This fan heater includes also a system for the re!iquefaction-21-. This unit can be used also for the dehydration (drying up) of certain standardized materials or products in bundles or different packing, with the use of conveyor belts or other mechanical or manuaily operated means.

The initial conveyor belt-2-, is formed by the rotating wheels-13-, the fixed wheels-14-the conveyor extensions-15- the receiving point-16-, the flow point of the product inside the unit-17-and the funnel-18-.

The final conveyor belt-6-is formed by the rotating wheels -13-, the carrying extensions-15-and the funnel-18-.

The central lower pipes-10-are formed by the"gasket"of the extension of the centra!pipe-19-, the damper-9-and the"gasket"for the connection with the branch-line or the fan heater-19a-.

The external tube-10-is formed by the connecting "gasket"to the fan heater-19b-the damper-24-25-and the apertures (upper-!ower)-26-27-. At the central tubes. down. there are reserve dampers-9f-and finally. there is a system

regulating the damper-20-The dampers can be automatically set.

The unit's operation is as follows : the loose product to be dehydrated (dried up) is collecte by the collection conveyor belt -2-. is raised and dropped at the beginning of the upper horizontal conveyor belt (with perforated floor surface)-4-.

The conveyor belt-4-deposits it at the space of unit-1- laying its surface flat, at different heights, according to the operational needs.

The fan heater produces air at different temperatures. pressures and quantities according to the operational needs. For this reason the fan heater is equipped with an automatic and a manual control system. This system regulates also the dehydrating process with hot air over 100°C or drying up process with hot air under 100°C.

The suitable for the dehydration (drying up) air is introduced into the branch-hne-11-, when the unit includes central tubes below. or directly to the tube-10-when the unit is with an external tube. It is then conducted into movements of different alternating directions and times according to the dehydration (drying up) process and in accordance with the air systems of its variants.

In order to achieve a uniform dehydration (drying up). the air passes in proportionate quantities and in specific areas of the product. wherever it is required. thanks to the special installation of a perforated floor surface-8-and conveyor belts (with

perforated floor surface)-4-4a-4b-7-with a specific density and number of perforations.

In general, the air is distributed from the lower part upwards and flows suitably through the tubes-10-10a-and the dampers which are manually or automatically regulated-9-9a-9b-24- 25.

The ready, dehydrated (dried up) product exits from the unit's door-5-or with the upper conveyor belt (with perforated floor surface)-4-which has the possibility to move upwards- downwards, or with the combined operation of the door and floor conveyor belts (with perforated floor surface)-5a-7-and the intermediate-4a-4b-according to the process for the delivery of the ready, dehydrated (dried up) product.

In continuation, the ready product is carried with final the conveyor belt-6-and is delivered for different standardization. transport, storage and other processes. For these needs, the fan heater-12-possesses a manual or automatic reliquefaction system, as required, of the already dehydrated (dried up) product.

The unit possesses, if required a complete electric or electronic system for the control and records the temperatures. humidities, pressures of the environment and the product and regulates automatically its operation, according to the cool- measuring diagram theory.

When a semi-automatic or manual operation is requested. the electric or electronic system provides the operational data and record the different necessary temperature. humidity and pressure parameters of the air. All the unit's mechanisms operate

and are controlled by a full electric panel installe in conformity to all regulations of good and safe operation of electric installations.

The fan heater can produce and forward to the air systems, different quantities and qualities of air, suitable for any form or quantity of dehydrated (dried up) product. The fan heater can operate under manual electric or automatic electronic control.

Thanks to the air distribution systems and the fan heater it possesses, the unit can also dehydrate (dry up) products that do not have the form of loose products or which do not flow, which will be introduced and extracted with other mechanical or manual means. When a partial reliquefaction is requested for the dehydrated product, the fan heater will possess a special mecha, nism for the reliquefaction of the air.

For the precise control of the dehydration (drying up), the unit possesses, when required, temperature, humidity and pressure sensors, which suitably installed will provide data to its electric or electronic operation control system. With the combined operation of the sensors and electric and electronic system, it is possible to control absolutely the amount of humidity which is removed during the dehydration (drying up) or which is added during the reliquefaction, when it is required.

In general, the electric and electronic system records the data and the results of dehydration, controls the temperatures, pressures and humidities of the fan heater and initiates and terminates automatically the unit's operation.
