MICROWAVE UNIT WITH TOROIDAL RESONATORS FOR SEPARATION OF HAIR COAT FROM RABBITS SKIN IN PROCESS OF BRINE SPRAYING Russian patent published in 2019 - IPC C14B1/02 C14B15/00 C14C1/06 

FIELD: physics.

SUBSTANCE: invention relates to microwave equipment and can be used for separation and collection of hair from rabbit hides. Microwave installation with toroidal resonators for separation of hair coat from skin of rabbit hides during brine spraying contains guide tube 1 located at an inclination. Inside tube 1 there moved is dielectric rope-washer 9 transporter. Toroidal resonators 4, 5 of circular cross-section are coaxially fitted on guide tube 1 through equal gaps providing for porosity of technological process of action of electromagnetic field of ultrahigh frequency less than 0.5. In central part 5 of each toroidal resonator 4, made in the form of parallel installed flat rings at a distance greater than a quarter of the wavelength, the dielectric perforated coupling 7 is coaxially located. It connects non-ferromagnetic guide tubes 1, sprayers 8 and pipeline for supply of brine 6 are supplied to them. Magnetrons 3 are installed in central parts of resonators 5. In toroidal part 4, the middle perimeter of which is equal to multiple of half of wave length, there is perforation. Dielectric washers 9 are attached to the dielectric cable from the peripheral side. At the ends of guide tube 1 there is loading 2 and unloading 10 branch tubes. Pneumatic line 11 is attached to unloaded perforated branch tube for transportation of hair coat.

EFFECT: proposed microwave installation with toroidal resonators for separation of hair coat from skin of rabbit hides during brine spraying provides acceleration of process of hairs removal after simultaneous disinfection of raw material without deterioration of fluff and skin quality.
