Description
Summary:The authors have developed ultra-high-frequency (UHF) devices of several types that are different in their operation and design principles. It is well known that the technological process of the animal product treatment includes a range of operations resulting in obtaining the final products and nonedible by-products approved for livestock feed manufacturing. Therefore, the development of technologies and technical means for treatment of slaughterhouse waste classed as nonedible animal by-products, which can provide the opportunity to make the processed protein product, is considered urgent. For this reason, surveys on UHF devices’ operating modes for thermal treatment of slaughterhouse waste were carried out. A description of the continuous mode operating principle of a UHF device combined with a resonator for the thermal treatment of nonfood by-products of raw meat material is reported. The combined resonator designed to ensure the electromagnetic safety limits is presented as a variation of a cylindrical resonator with a hemispherical base providing the raw material supply. The regression-based models optimizing the UHF device operating modes are developed. A description of the technology and the device for thermal treatment of the nonfood animal-origin raw materials under the impact of high-frequency electromagnetic fields, operating in the continuous mode, is reported. The properties of dielectric heating of the multicomponent raw material during its grinding in the resonator chamber and the analogs of the HVF devices are considered.
