Embodiment 1

[0017] Weigh 400kg and determine the content according to DB42 / T32.2-2002. The yellow ginger is washed, pulverized with 2 times the amount of water, and the pulverized material passes through the sedimentation separator many times to separate the saponin solution from the fiber and starch. 185 kg of a mixture of wet starch and cellulose was obtained, which was tested to contain 23.4 g of saponin, and the residual saponin was 0.86%. The separated saponin solution is added with an appropriate amount of polyaluminum iron sulfate flocculant to make the precipitation complete, and then separated by a centrifuge to make the saponin concentration reach 35-50%. Add 2-3% sulfuric acid solution to the concentrated saponin, pressurize to 0.2-0.3MPa, hydrolyze for 2-4 hours, and filter; add 1 / 3-1 / 2 of the filtered wastewater to the hydrolysate , And then add an appropriate amount of sulfuric acid solution to control the acidity at 1-2%, and perform pressurized hydrolysis under the above c...

Embodiment 2

[0020] Weigh 400kg and determine the content according to DB42 / T32.2-2002. The yellow ginger is washed and pulverized with twice the amount of water. The pulverized material passes through a sedimentation separator many times to separate the saponin solution from the fiber and starch. 171 kg of a mixture of wet starch and cellulose was obtained, which was tested to contain 24.0 g of saponin and the residual saponin was 0.91%. The separated saponin solution is added with an appropriate amount of polyacrylamide flocculant to make the precipitation complete, and then separated by a centrifuge to make the saponin concentration reach 35-50%. The filtered 1 / 3-1 / 2 of the wastewater is added to the hydrolyzed product, then an appropriate amount of sulfuric acid solution is added to control the acidity at 1-2%, and pressure hydrolysis is carried out under the above conditions to obtain a filter residue mixture and filtrate. The filter residue mixture was deacidified and dried to obtain...

Abstract

The invention discloses a cleaning and producing technology of turmetic produced saponin, which is characterized in that after turmetic is crushed to extract saponin, the separated saponin solution is added with a proper amount of flocculant for total sedimentation, and then, sediment is separated by a centrifugal machine; a proper amount of dilute sulfuric acid solution is added into the concentrated saponin, and then, the concentrated saponin is hydrolyzed and filtrated under the pressure; 1/3-1/2 of filtrated waste liquid is added into the hydrolyzed objects, and then, a proper amount of sulfuric acid solution is added for carrying out pressed hydrolysis according to the above conditions in order to obtain residue mixture and filtrate. The residue mixture can be changed into saponin by the processes of deacidification, drying, extraction, concentration, crystallization and drying. The cleaning and producing technology of turmetic produced saponin can cause a plurality of decanting centrifuges to be connected in series for use, so separation is simpler, and the residue amount of effective constituents is small. The flocculant used for concentrating saponin not only increases the concentrating efficiency of saponin, but also improves the concentrating degree of the saponin.

Description

Technical field [0001] The invention relates to a clean production process for producing saponin from yellow ginger. Background technique [0002] Yellow ginger is a medicinal plant, and the saponin extracted from it is widely used in the production of hundreds of hormone compounds or drugs, and has the reputation of "medicinal gold". However, the traditional processing technology of turmeric saponin has always been to pulverize turmeric as a whole, and acidolyze after fermentation. The process of extracting saponin from turmeric not only requires a lot of water, but also produces strong acid and high-concentration organic wastewater. The acid hydrolysis waste liquid contains high acidity, It has heavy gum, thick pigment, more foam, COD concentration is more than 300 times higher than the national first-level standard (100mg / L), and it has the title of "King of Wastewater". It takes 130-180 tons of fresh yellow ginger to produce one ton of saponin, 500 tons of high acidity waste...
