METHOD FOR PROGRESSIVE PREDEFECATION OF DIFFUSION JUICE Russian patent published in 2016 - IPC C13B20/00 

FIELD: food industry.

SUBSTANCE: invention relates to sugar industry. Method involves mixing diffusion juice with lime in amount of 0.25 % CaO to weight of juice and suspension of second stage juice saturation in an amount of 10-20 % to weight of diffusion juice at reverse motion, higher alkalinity with corresponding pH from 6.2 to 10.8-11.2. In diffusion juice before predefecation process antifoaming agent is added in an amount of 5-15 g/t of beet, and in zone of metastable predefecation, after coagulation threshold IUS with pH 8.2…8.6, - flocculant in amount of 2-5 g/t.

EFFECT: invention provides formation of sediment with high permeability and sediment properties, diffusion juice purification effect enhancement and reduction of total consumption of lime for cleaning.
