Device for producing ice water with ice accumulation by means of impulse freezing

Currently, there is a deficit in milk consumption per capita in the Primorsk territory. The Ministry of Agriculture of the Primorsky territory has set a task to stabilize the region's demand for this type of product. Providing the population with dairy products depends not only on animal husbandry, but also on the entire complex of machines associated with the stages of production of a wide range of dairy products. Also, an increase in the terms of product sales while maintaining quality requires at the initial stage of production the preservation of the basic properties of raw materials - milk, providing instant cooling at the milking stage. Foreign and domestic manufacturers produce a wide range of ice water generators, which are part of instant milk flow cooling units. The main drawback of serial machines is a decrease in the cooling capacity of the unit with a decrease in the water temperature, due to an increase in the layer of ice on the walls of the evaporator. The use of impulse ice freezing in panel-type ice water generators will reduce this disadvantage to a minimum. The described model of the ice water generator has the best indicators of energy efficiency when freezing ice. Structurally, it is carried out according to the traditional scheme, but unlike similar devices, the walls of the vessel are the evaporator, and the device operates in two modes - cooling and freezing. The cooling mode takes place at temperatures from +30 °С to +4 °С, in this mode all evaporators are involved. The freezing mode takes place at temperatures from + 4 °C to 0,7 °C, using only the bottom evaporator. Freezing of the ice layer alternates with the detachment of the resulting ice layer from the evaporator surface by supplying hot non-condensed refrigerant vapors to the evaporator.
