Currently, the Russian and foreign scientists are actively involved in the development of technologies for the processing and utilization of carbon dioxide. At the Kemerovo State University, the technologies for processing and application of carbon dioxide in the food industry have been developed. One of them is based on throttling the CO 2 coater in the generator. In order to determine the optimal operating modes of the generator, throttling is performed through washers with different throttle holes and their configuration. Also, throttling is performed with different angles of cones of snow formers at different temperatures of liquid carbon dioxide, which allows to reveal the influence of the above factors on the process of carbon dioxide snow formation. Based on the analysis of the obtained dependencies, we can conclude that the largest volume of snow weighing 0.25 kg was obtained using a cone with an angle of 12° and a temperature of minus 10°C. In percentage terms, 31.25% of the CO 2 consumed liquid phase was reworked into snow. The additional lowering of the temperature of the liquid carbon dioxide, as well as the choice of the optimum, for a given temperature, the angle of the bell, have a significant impact on the volume of the snow carbon dioxide produced. However, in the process of choosing the temperature control parameters, possible additional economic costs of creating conditions for lowering the temperature of liquid carbon dioxide should be considered.
