METHOD OF SAFE SEED DRYING Russian patent published in 2013 - IPC F26B3/06 

FIELD: agriculture.

SUBSTANCE: method of safe seed drying lies in that the material is charged, vented with the drying agent, cooled and discharged. A novelty in the invention is that the rate of drying agent is limited by the amount of heat-transfer coefficient α, which is defined as follows: where λ is the heat conduction coefficient of grains, W/m°C; ΔU is reducing the moisture content of grains, kg moist/kg mat; r is heat of evaporation, kJ/kg; σ is the thickness of the sphere of grains with the embryo, m; c is heat capacity of grains, kJ/kg°C; t_{d a} is the temperature of drying agent, °C; θ is temperature of seeds, °C; Ko is Kossovich number.

EFFECT: ability to use high-performance dryers while drying the luxury and high valuable varieties of seeds.
