GRAIN AND SEED DRYING METHOD Russian patent published in 2003 - IPC

FIELD: agriculture. SUBSTANCE: method involves active layer-by- layer ventilation of grain with air-and-ozone mixture having ozone concentration of from 1 mg/cu.m to 30 mg/cu.m and relative humidity of at least 75-80%. Thickness of first layer is determined from formula: h₁ = A•W^-3,7•C^0,2•V^0,8, of second and subsequent layers from formula: h₂ = A₁•W^-3,7•C^0,2•V^0,8, where W is basic moisture content of grain, %; C is concentration of ozone in mixture, mg/cu. cm; V is speed of air-and-ozone mixture in layer, m/s, with A and A₁ being coefficients used for wheat grain A=, for barley grain A=, and for oats grain A=28,5•10⁴ and A₁ = 26,9•10⁴. Method allows grain drying intensity to be increased by 1.3-1.6 times depending upon kind of cereal crop. EFFECT: increased efficiency, reduced volume of grain storage, and reduced consumption of heat power for drying process. 5 dwg, 3 ex
