Problems solved by technology

This technology has been used for many years, and its main problems are that the production technology is backward; the production cycle is long; the consumption of raw materials is large; the pollution is particularly serious; The extraction rate of saponin is 1.8-2.0%; the quality of the product is poor, and the melting point of the product saponin is generally 193-195°C; the labor intensity of the workers is high
According to statistics, for the production of 1 ton of saponin, 130-180

Embodiment Construction

[0010] refer to figure 1 , the pollution-free production method of turmeric processed saponin of the present invention, example is as follows:

[0011] Saponin extraction process: a, raw material pretreatment: wash turmeric with clear water, crush it with a crusher, and grind it into a slurry with a colloid mill after crushing, so that the particles of the turmeric pulp reach 140-150 mesh, and the concentration is 5-12%; b, Separation of saponin pulp: firstly use a separation garden sieve or gravity sieve to separate the fibers, and then use sedimentation to separate the starch with a heavier specific gravity to obtain saponin pulp. The starch is made into finished products for recycling, and the fiber is used as feed; c. Acid hydrolysis of saponin pulp : Carry out acid hydrolysis with sulfuric acid, pressure is controlled at 0.1~0.3MPa, obtains the saponin slurry after hydrolysis; The saponin pulp is filtered by plate and frame to obtain the semi-finished hydrolyzate and fil...

Abstract

The invention relates to a no pollution method for ginger processed saponin. It includes the following steps: washing yam, smashing, and grinding to slurry; depositing and separating to gain saponin slurry; acid hydrolysis saponin slurry; neutralizing and pressing, controlling the temperature at 40-80degree centigrade, pressure at 0.2-0.8MPa; distilling saponin. The waste water process method includes the following steps: taking fluid bed biology film process to the filtrate, accessing to compounding bacterium, the processed waste water could be directly discharged.

Description

technical field [0001] The invention relates to a pollution-free production method of processed turmeric saponin. Background technique [0002] Yellow ginger is a unique species in my country, and its rhizome contains a certain amount of saponin which can be hydrolyzed to obtain saponin. Saponin is an important pharmaceutical and chemical raw material for the synthesis of steroid hormones. It can synthesize more than 200 kinds of drugs in three categories: progesterone, anabolic hormone and adrenocortical hormone. Therefore, extracting saponin from turmeric has great pharmacological and market 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 technolo...
