Embodiment

[0038] A set of metal press rollers is used as the pressing equipment:

[0039] ① Wash 1500 grams of fresh turmeric with fresh water to remove impurities.

[0040] ② Adjust the roller spacing of the metal pressing roller to 2-3mm, start the motor, and add 1500 grams of fresh turmeric for pressing.

[0041] ③Adjust the roller spacing of metal press rollers to 0.3-1mm and 0.05-0.1mm respectively, and press once.

[0042] ④ Adjust the roller spacing of the metal press rollers to less than 5 microns, and press three times.

[0043] ⑤ Add the squeezed material into a container filled with 7500 grams of fresh water to make a slurry, and stir for 2 minutes.

[0044] ⑥ Filter the slurry of ⑤ through a stainless steel filter sieve with a pore size of 75 microns, and wash the filter residue once with the upper filtrate clear night.

[0045] ⑦Filter the filter residue of ⑥ with a filter cloth once, press out a large amoun...

Abstract

The invention discloses a method for circularly processing and utilizing rhizome in dioscorea, which comprises the following steps: washing the rhizome in a dioscorea plant and then removing impurities, squeezing for a plurality of times by a multi-stage metal roller, circularly adding water, slurrying, filtering with screening and filtering equipment, and circularly squeezing the separated dioscorea solid residue again; mixing the filtered slurry with a polyacrylamide flocculant, stirring, allowing the obtained mixture to enter a precipitator for sedimentation separation, and separating out dioscorea starch at a lower layer; and allowing an upper suspension layer to enter a helix discharging sedimentation centrifuge for forcible separation, and then rapidly separating dioscin slurry from the settled supernatant to finally obtain concentrated dioscin. In the method for circularly processing and utilizing the rhizome in the dioscorea of the invention, the water for washing and slurrying is from the settled supernatant of the precipitator and the helix discharging sedimentation centrifuge and can be recycled. The method solves the fundamental problem of processing and utilizing the rhizome in the dioscorea and greatly improves the economic value of dioscorea application.

Description

[0001] technical field [0002] The invention relates to a method for recycling processing and utilization of yam rhizomes, belonging to the field of agricultural product processing. Background technique [0003] Dioscorea rhizome is the raw material for producing diosgenin. Diosgenin, also known as diosgenin, or saponin for short, is a derivative of isospiroxane, which is the hydrolyzate of diosgenin in the rhizome of Dioscoreaceae plants, which widely exists in natural plants in the form of glycosides. , especially Dioscoreaceae has the most content. [0004] Dioscin has the effect of estrogen, which can lower cholesterol, relieve cough, eliminate phlegm, desensitize, restore diseased tissue, and stimulate heparin cells and bile secretion. It can be used as a semi-synthetic raw material for steroidal anti-inflammatory drugs, sex hormones, and female contraceptives. [0005] my country is rich in diosgenin resources and is the world's main producer of diosgenin. Howev...
