METHOD OF REFINING DIFFUSION JUICE Russian patent published in 2000 - IPC

Abstract RU 2160315 C1

FIELD: sugar industry. SUBSTANCE: diffusion juice, after separation of pulp, is heated and filtered through perlite bed to remove coarse particles. Filtered juice is subjected to membrane filtration in closed flow circuit of membrane installation with no air access on microfiltering membrane to produce filtrate containing low- molecular and colloidal substances and concentrate containing the rest of suspended particles, high-molecular substances, and microorganisms. Concentrate is treated with steam at 100-120 C for 1-2 min and transferred into perlite filtration stage. Invention allows purity of diffusion juice to be increased by 1.6-1.8% and filtration rate to be increased by 15-16%. EFFECT: enhanced refining efficiency. 1 dwg, 1 tbl, 2 ex
