Technology of Rabbit’s Fur Processing

Abstract

Analyzed shadowy the method of keeping rabbits, the design of cells. Developed two technologies of processing of skins of rabbits with use of energy of electromagnetic radiation. The first technology involves the drying skins of rabbits on pravicah in the electromagnetic field of ultrahigh frequency (MPSVC). Designed installation can provide periodic or continuous mode of operation. The second technology involves separating the fur from the leather hides of rabbits with the simultaneous rychle-tion, beating and separating fibres from bunches. Discusses the design of facilities that implement these technologies of processing of skins of rabbits. The sequence of development of technological process of heat treatment of fur raw materials: a study of the shapes and sizes surround the cavity of the microwave generator; the development of modes of processing of raw materials; selection of equipment and controls. Taking into account the structural features of the device, intended for primary processing of wool, developed by the working chamber of the microwave unit that provides the melting of the skin, breaking and separation of the fibers from the fur of fried dross. The working chamber is made in the form of a rotating perforated cylinder containing the inner side surface of the special pins. On the vertical axis of the cylinder, the shaft. On the shaft wearing the stationary pipe, the outer surface of which also has pins. The cylinder is coaxially installed in the cylindrical shielding housing containing an inlet for pneumatic transport fur squares. On the upper base of the body has a generator and the drum dispenser of raw materials. Proposed operational-technological scheme of processing of fur raw materials using electromagnetic fields of ultrahigh frequency. Analyzed electrical parameters of the components of raw materials. One of the proposed variants of the working chamber of the microwave installation, ensuring continuous operation. The working chamber is made as a coaxial screen-roumega housing, the perforated cylinder with pegs and hollow pipe with pegs, inside of which a shaft for rotation of the cylinder.
