METHOD OF COMBINED DRYING OF SEEDS AND GRAINS Russian patent published in 2015 - IPC A01C1/00 F26B3/14 F26B17/12 

FIELD: agriculture.

SUBSTANCE: seeds and grains are loaded, gravity mixing and reverse blowing with the drying agent is carried out with the cycles from 20 to 360 minutes. In the cycles, the drying agent with increased t₁ and reduced t₂ temperature is alternately used. The temperature t₂ is determined by the formula: where α is the heat transfer coefficient, W/m²·°C; f is specific surface of grains, m²/kg; η is the proportion of heat sent for heating; θ'_ma is the maximum allowable temperature of heating grain, °C; c is heat capacity of grain, kJ/kg·°C; Δθ is allowable amount of temperature increment of grain, °C; τ is the duration of the impact of the drying agent with increased temperature, h.

EFFECT: energy saving by increasing the intensity of the process.
