LN BURKOV'S DRYING METHOD Russian patent published in 2010 - IPC A23L3/00 F26B17/00 

FIELD: food industry.

SUBSTANCE: according to the method suggested, several drying stages in the form of flat inclined conic sieves oscillating or rotating with constant speed are mounted successively one after another in the moving heat-carrier flow and drying agent is directed through them in the form of a flow with constant or variable velocity and density. Heat carrier temperature is raised from stage to stage at an equal value. Holes of all the sieves are round and they are positioned in parallel rows with equal pitch equal to 2-3 lengths of the biggest fraction of the drying mixture and shifted one relative to another at half the pitch.

EFFECT: such method enables to improve quality of drying grain or seeds.
