METHOD AND DEVICE FOR PROCESSING WASTE OF ANIMAL-BREEDING COMPLEX Russian patent published in 1994 - IPC

FIELD: agriculture. SUBSTANCE: method involves diluting the waste before delivering it into a pressure-tight vacuum chamber and filtering it through multiple-layer filter. Heating is carried in several steps: to 30-35 C in the first container, 60-65 C in the second container and 80-85 C in the third one. Liquid fraction is separated by an injector in a chamber under a pressure of 0.4-0.6 atm. The amount of filtered liquid fraction entering the chamber is batched by vacuum gate valves installed at inlet and outlet of the third container and connected with level and temperature transmitters. Separated liquid fraction in then accumulated in the fourth container provided with temperature-stabilizing unit. EFFECT: improved functional and operating characteristics. 2 cl, 3 dwg
