Justification of parameters of microwave installation for separation of down from skins of rabbits in the continuous mode

Abstract

Discusses the problem of reducing the operating costs of decontamination and the separation of fluff from the skins of rabbits in rabbit farms. Rabbit meat production amounted to 4.2 thousand tons, of which 70% of the total volume of Russian production falls on farms. In the Nizhny Novgorod region effectively bred rabbits breed "White Giant", which at the age of 560 days reach up to 6.8 kg, but the processing of skins is quite time-consuming. Rabbit down is widely used in the processing industry as a raw material with unsurpassed qualities for the production of knitwear, felt, cloth. The article describes the developed microwave unit with a disk conveyor with a power consumption of 6 kW, a capacity of 16 kg / h. The results of experimental studies to substantiate the complex of structural and technological parameters and modes of operation of microwave installations based on regression models, taking into account the multicriteria assessment of the technological process of separating the disinfected down raw materials from the skin with the sponge-soaked Mezdra. The annual economic effect of the use of microwave installation for collecting hair from the skins of rabbits in rabbit farms is 187 thousand rubles.
