Dioscorea zingiberensis saponin extraction pretreatment device

Abstract

The invention relates to saponin, in particular to a dioscorea zingiberensis saponin extraction pretreatment device. The technical problem to be solved by the invention is to provide the diosgenin extraction pretreatment device. The dioscorea zingiberensis saponin extraction pretreatment device comprises a support frame, a control screen, a motor, a mud removal mechanism, a cellulose separation mechanism, a starch separation mechanism and a storage cabin, a control screen is arranged at the left part of the bottom end in the support frame, a motor is arranged at the middle-left part of the topof the support, and the mud removal mechanism is arranged at the left middle top in the support frame. The device has the advantages that soil on the surface of dioscorea zingiberensis is effectivelycleaned, dioscin aglucon dissolved in water is prevented from being lost due to water washing, cellulose and starch in dioscorea zingiberensis are separated out through cutting, squeezing and centrifugal precipitation, the situation that starch and cellulose in dioscorea zingiberensis are damaged and cannot be utilized in the acid hydrolysis process is avoided, meanwhile, starch is also hydrolyzed into glucose, and a large number of organic pollutants are generated.

Description

Technical field [0001] The invention relates to a saponin, in particular to a turmeric saponin extraction pretreatment device. Background technique [0002] The traditional turmeric saponin processing technology is basically: crushing-pre-fermentation-acid hydrolysis-hydrolysate extraction-saponin extraction, the pollution mainly comes from the hydrolysate processing process. Because this process only uses the saponin in yellow ginger, and discards other substances, such as starch and cellulose, which become pollutants into the wastewater, it wastes resources and increases the difficulty of wastewater treatment. The key technical link of the traditional process is to use acid hydrolysis to break the glycoside bond, but at the same time the starch in turmeric is also hydrolyzed into glucose, which produces a large amount of organic pollutants and becomes the main source of waste water pollution. According to conservative estimates, the organic matter produced after starch hydroly...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the problem that the cellulose and starch in the turmeric are not extracted in the prior art, the present invention will cause the starch and cellulose in the turmeric to be destroyed in the acid hydrolysis process and cannot be used, and the starch is also hydrolyzed into glucose. Produce a large amount of organic pollutants, because when removing the silt on the surface of turmeric, directly washing with water can cause the dioscin agenin soluble in water to be lost thereupon, make the shortcoming that the saponin that makes greatly reduces, the present invention will solve The technical problem is to provide a kind of turmeric saponin extraction pretreatment device
