FIELD: agriculture.
SUBSTANCE: grain is charged into airslide conveyor, ventilated with external and heated air and unloaded. The novelty of the method is the fact that discharge losses in ventilated layer ΔPc shall comply with the condition ΔPc<KP, and heating extent shall be limited with relative moisture of air coming out of the layer φ≤85…90%, where K=P/P1, P - full discharge of fan, P1 - discharge of fan at maximum delivery. Device for drying of seeds and grain comprises charging and discharging facilities, grid, fan and heater. The novelty of device is the fact that it is equipped with at least four sensors with relative air moisture φ, arranged over a layer of material along its length as pairwise in peripheral zone of chamber, and integrator connected to heater with the possibility to change temperature of heated air.
EFFECT: improved efficiency of seeds and grain drying.
