SEED AND GRAIN DRYING METHOD Russian patent published in 2006 - IPC F26B3/06 

FIELD: agriculture, food-processing industry and bakery industry, in particular drying of high-moisture content materials.

SUBSTANCE: method involves drying seed and grain in high-density layer rotating around vertical axis, said method being provided by blowing seed with drying agent; discharging insufficiently dried lower part of layer; providing softening and cooling in high-density layer by means of gaseous component until moisture content is higher than conditioned moisture content; after temporary storage and/or termination of harvesting season, returning material for drying process, with specific feeding of gaseous component being defined so that its temperature at the outlet differs from temperature within material layer by no more than 1-2 C. Frequency of returning insufficiently dried grain for drying process is defined by achieving conditioned moisture content of grain. Softening of grain having moisture content of 19.5-23% is provided for 6-4 hours. Batches of material delivered for drying, are moistened for 1-2 days.

EFFECT: reduced power consumption and improved keeping and preservation of wet seeds and grain.
