A microwave installation was created to boil waste products of poultry and animal slaughtering in a periodic mode. It consists of a horizontal cylindrical screening body. Inside it a perforated disc-rotor from non-ferromagnetic material, rotating the motor is installed. The cylindrical resonators are rigidly fixed on the periphery of the disc-rotor. Inside each resonator the removable dielectric heat resistant containers are mounted by clamps, which covers are perforated. The inner surface of the containers is covered with a silicone material. Microwave generator units are installed on the cover of shielded enclosure, opening with handles by hinges. At the base of the body there is a drain connection. To justify structurally and technological parameters of microwave installation we analyzed the changes in the electrical parameters of the muscle tissue, skin, bone, fat, depending on the frequency of electromagnetic fields exposure. The permittivity changes of raw materials, wavelength in the feed, penetration depth of electromagnetic radiation in the feedstock were also analyzed. The effect volume heating of inedible waste in the electromagnetic field is achieved due to penetration of the field into the feed to a considerable depth. At a certain depth of penetration it becomes possible to prove the form of processed raw material in resonator depending upon the requirements of the process and electromagnetic field parameters. The temperature and conductivity of the material greatly influence to the penetration depth.
