FIELD: agriculture. ^ SUBSTANCE: method to dry and unload seeds and grain (material), when they are loaded onto a grill in layers, actively ventilated and unloaded. The first layer of material is brought to a looseness condition, then reshaped with a slant at the grill outlet, and unloading is carried out with slant displacement to the grill inlet, besides, non-loose material arch is damaged with circulation of disperse phase, the solid part of which is involved both from the slant and from the arch. When the slant is displaced, it is arranged under the arch at the distance from the edge equal to äô>H ctqå, where H - maximum height of fill, å - angle of drying agent jets outlet from grill slots, active ventilation is carried out with a gas medium with relative humidity of not more than 75 %, the material of the first layer is dried by at least 0.5Ç3% in the moisture interval of 21Ç28%. ^ EFFECT: higher efficiency of airslide conveyor operation on material of higher moisture and infestation. ^ 5 cl, 2 dwg |
