METHOD OF SAFE SEED DRYING IN DENSE LAYER Russian patent published in 2017 - IPC F26B3/02 

FIELD: agriculture.

SUBSTANCE: invention relates to drying seeds mainly of premium varieties and can be used in agriculture and in the system of purchases. During drying, the seeds are charged in the dryer as a fixed bed with the height of 0.4-0.5 m, are treated with the drying agent with the consumption of 1800-1900 m³/(m²⋅h), cooled and discharged. The temperature of the drying agent is determined by the formula where A is the constant value for each crop; r is the specific heat of moisture evaporation, kJ/kg; α is the heat transfer coefficient, W/(m²⋅°C); f is the specific seed surface, m²/kg; ŋ is the portion of heat used for evaporation of moisture; θpd is the maximum permissible grain heating temperature, °C.

EFFECT: use of the invention will enhance the intensity of the seed drying process.
