METHOD OF SUGAR PRODUCTION Russian patent published in 2009 - IPC C13D1/08 C13D3/00 C13D3/02 

FIELD: chemistry.

SUBSTANCE: invention relates to sugar-producing industry. Method includes obtaining beetroot chips, scalding it before supplying into diffusion apparatus or its heating in it. Extraction of sucrose from chips with nourishing water, discharge from apparatus of diffusion juice and marc unloading are carried out. Water solution containing non-anionic flocculant and acid reagent are introduced into zone of nourishing water supply into diffusion apparatus body. Solution of inorganic coagulant and solution of calcium hydroxide are introduced into zone of beetroot chips supply or into medium zone of body of apparatus for beetroot juice purification from highly molecular compounds and substances of colloidal dispersibility simultaneously with extraction. Solution of inorganic coagulant and solution of acidic reagent are introduced into diffusion juice until pH of highly molecular and colloidal-dispersion admixtures in acidic medium is 4.5-5.5 Then solution of non-anionic flocculant and lime milk until pH is 6.5-8.5 are added to juice and are heated to 60-65°C. Reagent, accelerating process of non-sugar particles flocculation, is introduced and formed sediment is separated, after which juice defecation to pH 10.8-11.4 is carried out. Solution of inorganic coagulant and decolourizing reagent are added to defecated juice, pH is brought to 9.1-9.3 with acidic reagent, heated to 70-75°C, pH is reduced to 7.8-8.2, filtered. Purified juice is directed to thickening and in boiling of fillmass.

EFFECT: increase of effect of beetroot juice purification at stage of extraction and lime purification, reduction of lime consumption and sucrose loss in filtration sediment.
