METHOD OF CRYOCONCENTRATING BLOOD PLASMA OF SLAUGHTERED ANIMALS Russian patent published in 2023 - IPC B01D9/04 

FIELD: food industry.

SUBSTANCE: invention relates to a method of cryoconcentrating blood plasma of slaughtered animals. A method of cryoconcentration of blood plasma from slaughter animals, in which freezing is carried out in a capacitive-type cryoconcentrator; cryoconcentration is carried out in 2 stages: in 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 70% of the mass of the original solution, then the concentrate is sent to the second stage, where freezing is carried out at a temperature of the heat exchange surface minus 4°C until the amount of ice formed reaches 45% of the mass of the initial 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 52% of the mass of the original solution, after which the concentrate obtained at the parallel stage is sent back to the first freezing stage.

EFFECT: method described above makes it possible to reduce the loss of dry substances in the resulting ice at a high degree of concentration of the blood plasma of slaughtered animals.
