FIELD: agriculture.SUBSTANCE: method of micronizing of fodder grain includes grain treatment in two stages by thermal energy and VHF energy. Thermal energy treatment is performed by heating the grain surface by vapour at the temperature T=180-300 °C, pressure 1.5-12 MPa within 10-60 s, by VHF energy at the same exposition the temperature inside the grains raised to the temperature equal the temperature on its surface. The heated mass is unloaded into the swelling chamber, with air temperature 20 °C and pressure 0.1-0.2 MPa, cooled down to the temperature 36-40 °C, and humidified by water shower down to 30-45 of % of humidity. The formed vapour is removed for preliminary thermal treatment of grain at the temperature 120-130 °C, pressure 0.1-0.2 MPa within 10-12 minutes in the heat exchange device of the feed bin. The treatment is performed in continuous flow in a pseudo-liquefied layer.EFFECT: offered method of micronizing of the fodder grain allows at continuous mode of operations in a close-loop in a pseudo-liquefied layer to improve quality of micronizing, to expand the assortment of the worked stock, decrease specific consumption and run time.3 dwg |
