DIFFUSION JUICE REFINING METHOD Russian patent published in 2002 - IPC

FIELD: sugar industry. SUBSTANCE: method involves settling protein compounds; providing defecation, first saturation processes; separating sediment from juice; providing second saturation and filtering. Protein compounds are settled by exposing diffusion juice to electromagnetic field of extremely low frequency range, or to electromagnetic field amplitude-modulated by oscillations of extremely low frequency range, or to electromagnetic field frequency-modulated by oscillations of extremely low frequency range, or to electromagnetic field phase-modulated by oscillations of extremely low frequency range. Intensity of each electromagnetic field is 120-1,400 A/m and exposure time is 10-60 min. EFFECT: reduced power consumption and decreased consumption of lime for defecation process.
