First, the working principle

After grain hoppers, elevators, slide tube into the oven, slowly downward by gravity flow, by tempering section, dryer section, to complete a dry; then by the institution cereal grain discharge auger to the next row, the hoist again cereal oven body back into the second cycle. Figure (cereals since first entering the drying section to moment moment second into the dry section of a cycle) into the circulation of grain at the same time, hot air from the hot air chamber continuously laterally across the thin layer drying section of the valley, so that the grain temperature precipitation. By excluding aircraft exhaust valley floor by the fan, the grain is dried so again and again, until the moisture content of grain warehousing required standards so far.

Cereals in tempering section unventilated heat, but maintain a certain temperature, due to the internal surface of the grain temperature and humidity difference exists, grain internal moisture move outwards, inside and outside the grain moisture balance.

Grain moisture content reaches warehousing standards, the grain discharge gate open, cereals no longer into the oven and head directly into the elevator grain discharge tube, from the plane.
