UNIVERSAL LOW-TEMPERATURE CIRCULATING-RECIRCULATING AERATION-TYPE GRAIN DRYER

摘要

The invention relates to agriculture. The grain dryer is in the form of a silo comprising a roof with a hatch, the cladding of which roof is fastened with a gap with respect to the upper end of a housing formed from two shells, namely an internal shell level with the generatrix of the housing in the form of a sectional perforated tubular aerator which is equipped at the top with a conical cover, and an external shell, said shells being connected with an intermediate space therebetween with the aid of longitudinal reinforcing ribs, and a conical base with a hatch. At the bottom, the housing is equipped with supporting posts and pipes which are connected to sources of a heat-transfer agent and an ozone-air mixture. The perforated aerator is formed from two autonomous sections divided by a movable barrier, and is connected to the sources for providing the heat-transfer agent and the ozone-air mixture in the upper part; in the lower part it is connected to sources for supplying environmental air. The technical result consists in ensuring gentle and high-quality drying of grain.
