INSTALLATION FOR GRANULATION OF GROUND RAW MATERIAL WITH TOOTH RING MATRIX DURING DIELECTRIC HEATING Russian patent published in 2019 - IPC B01J2/12 

FIELD: fodders.

SUBSTANCE: present invention relates to microwave equipment. Plant for granulation of crushed material with toothed annular matrices during dielectric heating includes ellipsoidal resonators 1 and toothed annular matrices 4. Inside each of two ellipsoidal resonators 1 made of equal lower and upper spherical parts there located are ring annular matrices 4 of dielectric material. They are installed between pressure dielectric rings 13. Upper dielectric rings are rigidly fixed to shafts, one of which is driven 7, and the second driven one is 11. Along external perimeters of ring annular matrices 4, to zone external gearing 9, screening rims 3 having inner slots for teeth are installed. In lower parts of ellipsoidal resonators 1 there are unloading circular holes 8, width of not more than a quarter of wavelength, and dielectric scrapers 6 attached to shafts 7, 11. In upper parts of ellipsoidal resonators 1 there are radiators 2 from super-high-frequency generators. At level channels for pressing 10, on inner side of toothed annular matrices 4, dielectric knife 5 is rigidly fixed to lower base of receiving tray 12 from non-ferromagnetic material installed under ellipsoidal resonators. Chamber for receiving crushed material 14, made from non-ferromagnetic material, located above ellipsoidal resonators, on lower base, in area external gear engagement 9 has a slot.

EFFECT: invention can be used in production of granulated feedstuffs, for example, from mixture of grain wastes and non-food wastes of animal origin, moisture content up to 25 %.
