FIELD: agricultural engineering.
SUBSTANCE: invention can be used for drying, heating, defumigation and fumigation of grain and seeds. Proposed hopper has housing, perforated-surface air distributing channels installed in housing and connected through air dispensing channel with fan. Housing is made in form of body-hopper of truck whose internal combustion engine plays part of source of thermal and mechanical energy. Fan installed on truck frame under can is connected with two inlet air intake branch pipes with shutters to take in warm air from hood space and atmospheric air, with adapter branch pipe connected with air dispensing channel and furnished with filter-dust trap and with hydraulic drive, and with control panel of hydraulic drive and air intake branch pipe shutters.
EFFECT: reduced time and energy consumption for treatment of grain material, reduced moisture content of material.
