DIFFUSION JUICE PURIFICATION METHOD Russian patent published in 2016 - IPC C13B20/04 

FIELD: food industry.

SUBSTANCE: disclosed is a diffusion juice purification method providing its defecation in defecator to alkalinity of 0.8-1.0 % CaO to the weight of product, saturation of defecated solution in the first direct-flow saturator, feeding it into counter-flow saturator, removal of saturated sugar-containing solution from the countercurrent saturator to the second direct-flow saturator. Then 3-5 times recirculation of overcarbonated solution from the second direct-flow saturator to the counter-flow saturator for mixing with incoming solution from the first direct-flow saturator, final saturation of the mixture to achieve pH 8.5-9.5 in counter-flow saturator, and filtering the solution. Saturation of defecated solution in the first direct-flow saturator is carried out to alkalinity of 0.30-0.35 % CaO. Method allows to enhance diffusion juice purification effect in average by 1.2 % and reduce purified juice colourity in average by 12.5 %.

EFFECT: diffusion juice purification effect enhancement.
