Abstract

The invention discloses a crop dryer which consists of an enclosed case body, metal supporting plates, electrode racks on the metal supporting plates, and a dehumidifier arranged outside and connected with the case body. The metal supporting plates and the electrode racks are arranged in the case body. The electrode racks are connected with a cathode of a high voltage cable; the case body is connected with an anode of a high voltage power supply. The supporting plates and the electrode racks form an electrostatic field; an air inlet and an air outlet are formed on the case body; the air outlet of the case body is connected with a return air inlet of the dehumidifier; and the air inlet of the case body is connected with an air outlet of the dehumidifier. Compared with the present processes of thermal drying and vacuum freeze drying, the crop dryer discharges no pollution, produces no residue, and is low in energy consumption and dryness cost. The content of index components in a dried material is increased. The economic and social benefits are significant. In limited temperature regions, the drying speed of the drying process of the crop dryer is approximately twice as high as the thermal drying speed. If the drying process of the crop dryer is combined with the thermal drying, the drying effect can be doubled. The material is not required to be heated when the crop dryer works; the content of the index components in the dried material keeps high; and the crop dryer is low in operating cost.

Description

technical field [0001] The invention relates to a drying device, in particular to a drying device for crops. Background technique [0002] At present, the traditional drying method of materials usually adopts thermal method and vacuum freezing method. The disadvantage of the thermal method is that the quality of the dry product is poor and the loss of index components is large; the disadvantage of the vacuum freezing method is that the equipment investment is large and the operating cost is high. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a crop drying device, which is a brand-new drying method, especially suitable for drying heat-sensitive substances, and has the characteristics of significant energy saving. [0004] The technical scheme that realizes the object of the present invention is: [0005] A crop drying device, which is composed of a closed box body, a metal receiving pla...
