METHOD FOR OBTAINING SEA BUCKTHORN JUICE Russian patent published in 2023 - IPC A23N1/00 

FIELD: food industry.

SUBSTANCE: method for obtaining sea buckthorn juice includes crushing raw fruits while maintaining the integrity of the seeds, heating the resulting fruit pulp to a temperature of 60-65°C, separation of sea buckthorn juice from the fruit pulp, dilution of the fruit pulp with water, separation of the resulting mixture into diffusion juice and components containing sea buckthorn oil. Crushing of raw fruits is combined with heating and is carried out in a horizontal dismembrator with a heated rotor and stator. Sea buckthorn juice, separated from the fruit pulp, is filtered in a screw conveyor through holes with a diameter of 0.4-0.6 mm. Dilution of the fruit pulp is carried out with distilled water in a ratio of 1:3. Diffusion juice is concentrated in an evaporator at a residual pressure of 60-65 kPa with dead steam to a concentration of filtered sea buckthorn juice; concentrated diffusion juice and sea buckthorn juice are mixed and cooled in a blow tank by lowering the pressure of the medium to 1.0-1.2 kPa and separated in a horizontal gravity separator into clarified sea buckthorn juice and oil-containing mass. Moreover, the secondary steam in the evaporator is ejected by its primary steam. The pressure reduction is ensured by the removal of secondary vapor from the blow tank by a barometric mixing condenser and is collected in a condensate collector. The heating of the rotor and stator of the dismembrator is carried out with condensate from the evaporator and then the condensate is collected in the condensate collector. Heating and cooling of parts of the condensate from the condensate collector is carried out due to the reverse Carnot cycle by the operation of the compressor unit, in which one third of the condensates from the evaporator and secondary steam from the blow tank are cooled to a temperature of 4-6°C and fed as a refrigerant to the mixing condenser, and the other part is heated to 60-65°C and served as distilled water at the dilution stage.

EFFECT: invention is aimed at obtaining a high yield of high-quality sea buckthorn fruit juice, as well as reducing energy costs for processing sea buckthorn fruits.
