Clean production method for processing saporin from yellow ginger

Abstract

This invention relates to a method for processing soap matters with gingers characterizing in washing, crushing, grinding and sieving them to separate rough fibers then depositing crude slurries, then the mixed solution of the starch and saponin is multienzymolyzed to separate saponin slurry and grape sugar, in which, the saponin slurry is concentrated, deposited naturally then to separate and purify the pectin, the saponin solution is hydrolyzed to get soap matters and acid waste water, which is neutralized and passes through iron beds to enter into an anaerobic baffle reactor, to a UBF compound anaerobic processor to progress in CASS circulation active mud system and applies biological active carbon to process them to reach the standard to be discharged.

Description

technical field [0001] The invention relates to a method for processing saponin from turmeric. Background technique [0002] Yellow ginger is a unique species in my country, and its rhizome contains a certain amount of saponin and its hydrolyzed product saponin. Saponin has multiple pharmacological effects such as hemolysis, blood lipid lowering, antibacterial, and anti-inflammatory. It is an important pharmaceutical and chemical raw material for the synthesis of steroid hormone drugs and steroidal contraceptives. Therefore, extracting saponin from turmeric has great pharmacological and long-term value. Since the 1970s, the process of processing turmeric saponin has generally been to wash and crush the turmeric into a slurry, then ferment the slurry naturally, then add acid hydrolysis to the fermentation product to hydrolyze the saponin to produce saponin, and then wash After removing the acid water, dry it, and then use No. 120 gasoline to extract the saponin. This techn...

Problems solved by technology

This technique has been used for many years, and its main problems are that the production process is backward; the production cycle is long; the consumption of raw materials is large, and the extraction rate of saponin is low. The saponin extraction rate of fresh turmeric is 0.6-0.8%, and the extraction rate of dry turmeric 1.8-2.0%; product quality is poor, the melting point of product saponin is generally 193-195 ° C; labor intensity is high; the degree of resource utilization is low, 50% fiber, 40% starch and a small amount of pectin in dried turmeric have not been recycled Pollution is serious, according to statistics, every production 1 ton of saponin needs 130-180 tons of turmeric, 15-20 tons of 35% industrial hydrochloric acid, produces 400-500 tons of waste water, waste water COD up to 30000mg / l, BOD8000mg / l, waste water The pH value is 1.0-2.5. Due to the large water consumption, most saponin production enterprises are built near the water source, and the wastewater discharged outside causes great pollution to the water environment.
