Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 and 2: an agricultural product drying device comprises a shell 1, wherein a plurality of mesh material trays 2 are arranged in the shell 1 at equal intervals in the longitudinal direction, a partition plate 3 positioned above the mesh material trays 2 is further arranged on the upper portion of the shell 1, a plurality of air outlet hole groups are uniformly distributed in the circumferential direction and arranged on the partition plate 3, each air outlet hole group consists of four air outlet holes 4 distributed in an array manner, two temperature and humidity detectors 5 are further arranged in the shell 1, the two temperature and humidity detectors 5 are respectively arranged on the upper portion and the lower portion of the shell 1, a dehumidifier 7 is further arranged at the bottom of the shell 1, an air outlet pipeline 8 is connected to the side wall of the bottom of the shell 1, the outlet end of the air outlet pipeline 8 is arranged upwards, and a cover plate 9 is hinged to the outlet end of the air outlet pipeline 8,

The utility model discloses agricultural product drying device's working process as follows: when some agricultural products need to be dried, the agricultural products are uniformly placed on the mesh-shaped material tray 2, then an instruction is sent through the controller 16, the execution mechanisms are controlled to cooperatively act, under the action of the air blower 15, outside cold air enters the air inlet pipeline 10 and is heated under the action of the straight-through solar air heat collector 11 or the electric heating device 12, after hot air enters the shell 1, the hot air firstly enters the cavity above the partition plate 3 and then enters the space below the partition plate 3 through a plurality of groups of air outlet holes formed in the partition plate 3, and because the air outlet holes are uniformly distributed in the circumferential direction, the hot air can uniformly flow under the guiding action of the air outlet hole groups, so that sufficient flowing hot air is ensured to be arranged at each position in the inner cavity of the shell 1, and a local high-temperature area is avoided; meanwhile, the aperture of the air outlet 4 is smaller than the diameter of the cross section of the shell 1, so that the flow velocity of the air can be accelerated;
