DETAILED EXPLANATION OF THE INVENTION

[0036] In the drier with solar simulator; there are trays (1) of which the dimensions and number may vary. The fresh products (fruits, vegetables) to be dried are placed on the mentioned trays (1). There are very small holes in the structure of the mentioned trays (1) which enable air flow to pass through.

[0037] In the drier with solar Simulator; there are IR-UV slots (2) (IR-UV sources) that provide the rays required for the drying process to be sent to the mentioned trays (1). The number of the mentioned IR-UV slots (2) vary as based on the dimensions of the trays (1). IR and UV rays mix is released from IR-UV slots (2). IR-UV rays mix is sent at the amount, duration and angle required by the drying process which is determined and selected over the computer panel. This way, the water and moisture content in the structure of the foodstuff, which is placed on the trays (1) are evaporated and removed.

[0038] The mentioned vapor is directed by the fans (6) on one side of the drier with solar simulator towards the aluminum condensation surface (3) on the other side. For an effective condensation, the mentioned aluminum condensation surface (3) is supported by the cooling liquid channels (4) through which cold water runs.

[0039] In the drier with solar simulator, all the surfaces, except the aluminum condensation surface (3), are covered by insulation material (7).

[0040] In order to turn the foodstuff during drying process; there are resonance motors (5) under each tray (l). Vibration can be given to the trays (1) at the desired duration and at the desired intensity by the mentioned resonance motors (5). The foodstuff on the tray (l) is also moved by this vibration. This way, the surface area on the foodstuff which is influenced by IR-UV rays is enlarged.

[0041] Following the termination of the drying process; the trays (1) are rotated by 10 to 90 (preferably 15) by an arm or a motor connected to them. Upon rotation of the trays (1); the dried products are transferred to the product discharge section (9) located at the bottom part of the drier. The dried products are transferred to the packing unit from the mentioned product discharge section (9) via closed conveyor system. This way, dried products are packed and put out on market at the desired amounts and sizes without any manual contact.

[0042] As a model version of the invention, the food drying method in the drier with solar simulator is realized as follows:

[0043] The user places the fresh foodstuff (fruit, vegetable), which is desired to be dried, on the trays (1) of the drier with solar simulator. Then the user selects the (identified) drying process (program) from the computer control unit, which is appropriate for the foodstuff on the tray (l). Based on the drying program selected; the parameters such as angles of IR-UV slots (2), amounts of IR-UV rays, drying time, fan (6) speed and angle, vibration frequency of the resonance motor (5) etc. are adjusted optimally in compliance with the characteristics of the product on the tray (l).

[0044] The drying process is carried out by the IR-UV radiation given from the IR-UV slots (2). While the product on the tray (l) is exposed to IR-UV radiation, the resonance motors (5) provide the vibration of the tray (l). By the vibration of the tray (l), the surface of the product on the tray (l), which is exposed to IR-UV radiation is increased. Thanks to the micro holes on the trays (1), formation of the air flow on the surface of the foodstuff contacting the tray (l) is enabled.

[0045] The evaporation process of the water content in the fresh foodstuff, which is exposed to IR-UV radiation, starts. Moreover, vitamin D synthesis is started in the foodstuff, thanks to UV radiation.

[0046] Water vapor evaporated from the foodstuff is directed to the aluminum condensation surface (3) via the fan (6) or the fans (6). Water vapor arriving at the aluminum condensation surface (3) is condensed (becomes liquid again) and flows to the liquid discharge channel (8). There are cooling liquid channels (4) within the structure of the aluminum condensation surface (3). Condensation process is faster and more effective thanks to the cooling liquid flowing through the cooling liquid channels (4).

[0047] When the drying process is completed; the trays (1) are rotated for example by 45 by an arm or a motor. When the trays (1) are rotated; dried foodstuff falls into the product discharge section (9). The dried products are transferred to the packing unit from the mentioned product discharge section (9) by a closed conveyor system. This way, dried products are packed and put out on market at the desired amounts and sizes without any manual contact.

[0048] In addition; drying processes according to each foodstuff is programmed in the computer control unit of the drier with solar simulator. The user can select the settings according to each foodstuff, by a single selection.
