摘要：

The paper presents the design of a device for the low-temperature separation of liquid media with two-stage freezing using frozen ice as a cold-accumulating mass for product pre-cooling. A method for calculating the dynamics of the water ice freezing on the inner cylindrical surface, represented by the working surface of the proposed device, is proposed. The efficiency values of single- and two-stage freezing devices are compared.
