Тhe dairy industry is undergoing changes due to ever-increasing technologies and introduction of technological advances, which have many advantages. However, each new technology causes some difficulties. For example, summer camps are widely used for keeping cows in the summertime, which are 3 to 10 km away from the main farm. The main, unresolved problem in such camps, which is ubiquitous, is cooling of fresh milk. On the main farm, as a rule, cooling is carried out by machines. But to use refrigeration equipment in summer camps is not economically feasible. Milk, most often, is not cooled, but transported to a dairy processing plant. Taking into account the duration of milking and subsequent transportation, the duration of the stay of fresh milk without cooling is several times higher than the permissible values. In reducing the grade of milk in such cases, manufacturers suffer large financial losses. Milk can be cooled in such cases by the natural cold accumulated in winter in the form of water ice. Such accumulation can be carried out using a thermosiphon system. However, in such a system, freezing of ice will inevitably lead to destruction of the ice accumulator. We propose a relatively simple and low-cost method of protecting the pool walls in a remote camp while freezing ice with a thermosiphon system. This will allow to completely eliminate the destruction. Also, this method is economically feasible due to reduction of the transportation costs and cooling of the milk itself with the help of refrigeration units with high power consumption.
