METHOD OF PREPARATION OF WHEAT GRAIN FOR MILLING Russian patent published in 2017 - IPC A23B9/00 

FIELD: technological processes.

SUBSTANCE: invention relates to the processes of drying and storing of grains. The method of preparation of wheat grain for milling involves drying, cooling and silo storage of grain, heating of drying agent before drying in a condenser of a vapour compression heat pump with a two-section evaporator; removal of exhausted drying agent for grains preheating and subsequent purification in a cyclone, drying and cooling in a working section of the evaporator with return in the condenser and in closed-loop mode with supply for drying; cooling the grain to be dried and its active ventilation during silo storage cooled by a part of the drying agent with uniting the flows of the exhaust drying agent after drying and active ventilating before supply into the cyclone; supply of water heated in the condenser to the evaporator section. After silo storage of wheat first the separation of impurities is performed, and then cleaning the grain surface by flaking in hulling machine and wetting in a wet peeling machine. The hulled grain is supplied into the intensive wetting machine and then to the bins for binning. Shells are supplied to a screw press and their mechanical squeezing is performed. After the screw press the shells are ground and supplied for drying, after which they are extracted from production as raw materials for compound feed. Hulled grain in two stages is sequentially supplied to the intensive wetting machines and to the bins bins for binning. The final extraction of impurities is performed and then it is supplied to the milling section.

EFFECT: invention will allow to improve the ready product quality.
