METHOD OF ORANGE JUICE CRYOCONCENTRATING Russian patent published in 2023 - IPC A23L2/02 A23L2/08 

FIELD: food industry.

SUBSTANCE: invention relates to production of concentrated orange juice. A method of cryoconcentration of orange juice has been proposed, within the said method freezing is carried out in a container-type cryoconcentrator, and cryoconcentration is carried out in 2 stages: in the first stage, the original orange juice with a solids content of 12.3% is subjected to freezing at a heat exchange surface temperature of minus 3.5°C until the degree of freezing reaches 50% of the mass of the original solution, the ice is melted and removed from the cryoconcentrator, the resulting concentrate with a dry matter content of 19.7% is sent to the second stage, where freezing is carried out at a heat exchange surface temperature of minus 5°C until the degree of freezing reaches 42% of the mass of the original solution, the ice is melted and removed from the cryoconcentrator and a concentrate with a dry matter content of 28.3% is obtained, while the ice formed at both stages after melting is mixed and sent to a parallel freezing stage at a temperature heat exchange surface minus 3°C until the degree of freezing reaches 55% by weight of the original solution, the resulting concentrate with a dry matter content of 12.3% is sent back to the first freezing stage.

EFFECT: invention reduces the loss of dry matter in the resulting ice to 1.5% while increasing the concentration of dry matter in orange juice by 2.3 times.
