MULTIZONE CONTINUOUS-BELT DRIER FOR DRYING OF LOOSE AND POORLY LOOSE MATERIALS Russian patent published in 2001 - IPC

FIELD: agricultural machine building, particularly, machines for drying of loose granular materials, more specifically, cereal crops and poorly loose materials such as flaxseed thrashed heaps. SUBSTANCE: drying is carried out by formation of periodically operating zones of heating, resting and cooling on sections of drying agent transversely directed to periodically moved material in direction of transportation by means of installation above working branch of conveyer 9 of alternating pressure and suction boxes 21, 22, 12 and 7, 19 whose bottom bases have inclined plates 3, 8 ensuring reverse motion of drying agent through drying chamber. Installed under working branch of conveyer 9 alternately are suction and pressure boxes provided with perforated bottoms. 13. Said boxes ensure motion of drying agent in vertical direction. EFFECT: higher reliability of drying cereal crops and poorly loose agricultural materials.
