(54) DEVICE LLYA OF DRYING OF PLANT RAW MATERIAL ARG

(57) The invention relates to a technique for drying fruit and vegetable crops using solar energy. The purpose of the invention is to expand technological capabilities and improve the quality of drying by creating favorable drying conditions for fruit and vegetable crops when processing small amounts of raw materials. The chamber 1 for drying plant materials has perforated walls and a bottom, and the lid 8 of the chamber 1 is covered with black plastic film, and the chamber 1 itself is mounted on the screen 11 of a similar film. Thanks to such a device, the camera 1 creates favorable conditions for drying year, vegetables and fruits. 1 z.p, f-ly, 2 ill.

The invention relates to a technique of drying fruit and vegetable crops using solar energy during their processing and long-term storage and can be used in the processing of small amounts of raw materials.

The aim of the invention is to expand the technological capabilities and improve the quality of drying.

FIG. 1 shows the device, frontal section; in fig. 2 shows section A-A in FIG. one.

The device comprises a chamber 1 in the form of a rectangular duct formed by a lower metal frame 2, an upper wooden frame 3, reinforced with each other by means of straps 4, terminating in legs 5. 8 lid attached, black polyethylene chickpea

a black film 9 and reinforced with the help of strips 10. Under the chamber 1, a screen 11 is also installed of black plastic film, not less than 1.5 times the bottom area.

The device works as follows.

Opening the lid 8 on loops 7, load the fruits to be dried on the bottom of the chamber 1, close the lid, take the device to the area lit by the sun, and place it on the screen 11 made of black plastic film A high-temperature local medium is created from the black plastic film in the dryer to provide an intensive release of moisture from the drying products, which is removed through the mesh 6 to increase

natural ventilation. At the end of the drying process, finished products are removed and the chamber is loaded with fresh raw materials.

The proposed device allows to obtain high-quality dried vegetables, years and fruits in household conditions without using complex devices, protects the product during drying from direct sunlight, from the effects of precipitation, eliminates the contact of drying with insects that cause harm. for drying products, provides a more efficient use of solar energy during the drying of products, reduces the labor intensity during the loading and unloading of drying products, reduces the drying time.
