METHOD FOR TREATMENT OF RAW PLANT MATERIAL AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 2007 - IPC A23K1/12 A23K1/22 A23N17/00 

FIELD: agriculture, in particular, preparing of feeds for animals.

SUBSTANCE: method involves steaming-through raw material impregnated with acid solution; grinding raw material and delivering into reactor; sealing reactor; holding raw material under reduced pressure in reactor; feeding hot acid solution into reactor; providing impregnation of raw material with acid solution and hydrolysis under excessive pressure during time period of up to 3 hours; maintaining temperature of 85-100 C in reactor during hydrolysis process; upon termination of hydrolysis process, drawing acid solution from reactor through pipeline into working reservoir, wherein neutralizing acid using reactant having acidity of 6.0-7.0; drawing neutralized liquid from reservoir back into reactor and repeatedly impregnating raw material with liquid; holding raw material within reactor during 5-25 min; drawing liquid from reactor into reservoir and controlling its acidity; in case of occurrence of acidic reaction, providing liquid neutralization until pH value is 6.0-7.0; drawing liquid back into reactor containing raw material and impregnating the latter with liquid; repeating cycle until neutrality is stabilized within the range of pH=6.0-7.0 and drawing working liquid into reservoir; unsealing reactor; withdrawing and using resultant product as animal feed. Apparatus has reactor formed as reservoir with cover to be opened or hermetically closed, and working reservoir with cover to be opened and hermetically closed. Vacuum type delivery pump, hot water and gas generator are connected to reactor and working reservoir through pipelines equipped with locking-and-adjusting valves. Reactor and working reservoir are furnished with controlling and measuring instruments and safety-bypass valve.

EFFECT: improved quality of feeds and reduced power consumption.
