METHOD FOR DRYING RAPESEED UNDER QUASI-ISOTHERMAL CONDITIONS Russian patent published in 2024 - IPC A23B9/08 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of grain storage at grain receiving stations. A method for recirculation drying of rapeseeds under quasi-isothermal conditions has been proposed, consisting of mixing raw and recirculating seeds, preheating the mixture with a drying agent with the temperature of 260-300°C to the temperature of 60°C, heat and moisture exchange between raw and recirculating seeds and subsequent distribution into two shafts, where they are blown with atmospheric air, after which the dried seeds from the recirculating shaft are mixed with raw seeds and sent for re-drying, the dried and cooled seeds from the cooling shaft are sent for storage. At the same time, a drying agent at a temperature of 80-100°C is supplied to the upper zone of the two shafts. After drying, the seeds are cooled in the lower zones of the recirculation and cooling shafts by blowing them with atmospheric air, while the pressure-distribution chamber is divided by a vertical partition.

EFFECT: improved efficiency of drying rapeseeds.
