MILK CRYOCONCENTRATION METHOD Russian patent published in 2023 - IPC B01D9/04 A23C3/04 

Abstract RU 2805849 C1

FIELD: food industry.

SUBSTANCE: production of concentrated milk. Cryoconcentration of milk is carried out in a capacitive cryoconcentrator in two stages: at the first stage, the temperature of the heat exchange surface is minus 2°C, freezing is carried out until the amount of ice formed reaches 65% of the mass of the original solution, then the concentrate is sent to the second stage, where freezing is carried out at a heat exchange surface temperature of minus 4°C until the amount of ice formed reaches 48% of the mass of the original solution, and the ice formed at both stages after melting is mixed and sent to a parallel freezing stage at a heat exchange surface temperature of minus 2°C until the amount of ice formed reaches 35% of the mass of the original solution. After this, the concentrate obtained in the parallel stage is sent back to the first freezing stage.

EFFECT: increasing the concentration of dry substances by 2.3 times, and the use of a parallel stage makes it possible to reduce the loss of dry substances in the resulting ice to 4.6%.
