In recent years, for cold treatment of poultry there is a variety of devices, operating on the prin-ciple of direct contact with carbon dioxide. The dis-advantages of these contactors are relatively low productivity, increased consumption of CO2 and its not sufficiently effective use. The paper presents the design and operation of the refrigeration appa-ratus for processing poultry, construction of which is to compensate for these shortcomings. In order to implement the developed machine industry ex-perts in the Kemerovo Technological Institute of Food Industry (University) on the faculty of heating and air conditioning a working model of the machine and made some studies of its operation modes were developed. During operation of the apparatus the cooling time of bird’s flow of carbon dioxide at various masses poultry and apparatus modes was defined. The proposed device for refrigeration treatment of birds with carbon dioxide has increased productivity, it reduces the flow of carbon dioxide, is efficient in using.
