METHOD OF PROCESSING MUSTARD OIL CAKE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC A23K1/14 

FIELD: agriculture.

SUBSTANCE: method comprises moistening the oil cake with water when stirring, heating, keeping the moist oil cake to remove water vapour with volatile oil of mustard and subsequent drying under vacuum. The oil cake is preliminary crushed to 0.6-0.8 mm, moistening is carried out by spraying aqueous solution heated to a temperature of 65-70°C containing ascorbic acid and sodium chloride at a ratio of water:(ascorbic acid and sodium chloride) equal to 400:1. At that the ratio of ascorbic acid to sodium chloride is equal to 1:4, with the ratio by weight of the oil cake to water of 2.7:1. Keeping the moist oil cake is carried out for 30-35 minutes at the excess pressure of 1.2 atm and additionally ultrasonic treatment is carried out for 5-10 minutes simultaneously with moistening and drying under vacuum. The device for processing mustard oil cake comprises a housing with a jacket for heating, an agitator with paddle stirrers, a loading device for inputting the main component, and the loading device for output of the finished product, a supply system of moisturizing liquid, a vacuum system, a source of ultrasonic treatment. The housing is made in the form of two interconnected horizontally arranged half cylinders, each of which comprises a shaft with vanes for stirring mounted with the ability of adjustment of the speed of stirring, mounted with the ability to move the vanes of one shaft between the vanes of the other shaft during rotation of the shafts. The supply system of moisturizing liquid is made in the form of spraying nozzles mounted along the shafts. The feeding device for inputting the main component and the discharge device for output of the finished product are made in the form of hatches with the valve vacuum gate.

EFFECT: increase in the nutritional value of the feed additive obtained, increase in the degree of purity of the volatile oil of mustard, decrease in energy and time consumption.
