METHOD FOR PREPARING NUTRIENT WATER FOR DIFFUSION Russian patent published in 2003 - IPC

FIELD: sugar industry. SUBSTANCE: method relates to production of sugar and involves alkalinization of mixture of ammonia and barometric water with milk of lime and deammonization. Then water is saturated, formed precipitate is removed and sulfinated. Deammonization and saturation of mixture is carried out simultaneously at pH 7.7-8.3. Sulfitation of nutrient water is carried out to pH 6.4-6.5 and then binary non- ammonizated superphosphate in the amount 0.02-0.04% to water mass is added to sulfinated water. Invention provides minimal amount of ammonia, reduction of microorganisms content and other impurities and improvement of quality of diffusion juice as result of diffusion using. EFFECT: improved preparing method.
