Problems solved by technology

[0005] The main technical problem to be solved by the present invention is that the raw materials in the diosgenin extraction process do not undergo fermentation treatment, which shortens the process: the waste liquid after catalytic cracking with strong acid is not discharged, environmental pollution is eliminated, and production costs are reduced; the diosgenin is extracted The final waste residue can be comprehensively utilized to produce bio-organic fertilizer

Embodiment 1

[0014] Embodiment 1: Take 1000 kilograms of fresh turmeric as raw material, wash and pulverize it and put it in a container, add clear water and stir evenly according to 1:2; use ultrasonic treatment for 1 hour to break the wall of plant cells; put the treated turmeric into a cracking tank , add 300 kg of hydrochloric acid, at 2Kg / cm 2 Under the pressure of 2 hours, cleavage 2 hours; Add 396 kilograms of sodium hydroxide, make the lysate carry out neutralization reaction to neutrality; Split the cleavage mixture in the distillation still, carry out distillation, the mixed liquid that comes out through condenser condenses enters recovery device, When the water content of the cracking mixture reaches 30%, the material is discharged and dried, and the moisture is controlled at 3-8%; the cracking mixture after drying is passed through CO 2 Supercritical extraction of diosgenin can obtain 10 kg of diosgenin, and the yield of saponin is 4%.

Embodiment 2

[0015] Example 2: Take 1000 kg of fresh pangolin as raw material, wash with water and crush it, put it in a container, add water at a ratio of 1:3 and stir evenly; use ultrasonic treatment for 1.5 hours to break the plant cell wall; put the treated pangolin in lysate In the tank, add 100 kg of sulfuric acid, at 3Kg / cm 2 Under the pressure of 4 hours, split 4 hours; Split the cracked mixture into the still, add 110 kilograms of sodium carbonate, make the lysate carry out neutralization reaction to neutrality, do not pass through the condenser, by increasing the temperature of the still, make the cracked mixture contain When the water content reaches 25%, the material is discharged and dried, and the moisture is controlled at 3-8%; the cracked mixture after drying is passed through CO 2 Supercritical extraction of diosgenin can obtain 8 kg of diosgenin, and the yield of saponin is 3.7%.

[0016] The cell wall breaking process in the above two embodiments can also be processed b...

Embodiment 3

[0018] The waste residue after 1000 kilograms of fresh turmeric extracts diosgenin is 120 kilograms, produces bio-organic fertilizer according to the preparation process provided by the present invention: waste residue after extracting diosgenin and chicken manure, cottonseed cake or bean cake, according to waste residue 30%, chicken manure 43%, cottonseed cake or bean cake 20%, superphosphate 5%, mix evenly, add microbial strain Sporosporium thermophile 2%, ferment for about 10 days, mix evenly, cold air granulation can produce bio-organic fertilizer 400 Kilogram.

Abstract

The method for extracting dioscorea saponin from yellow ginger and Japanese dioscorea includes the following steps: washing yield ginger and Japanese dioscorea, breaking them, adding clear water and uniformly stirring them, ultrasonic wave treatment, placing them into cracking tank, adding concentrated hydrochloric acid or sulfuric acid, cracking under the condition of a certain concentration andpressure, adopting sodium hydroxide and potassium hydroxide to neutralize crackate to neutrality, distilling crackate mixture, when the water content is up to 15-40%, discharging material, drying to control water content in 3-8%, and using supercritical Co2 extraction process to obtain dioscorea saponin, and utilizing waste dregs produced after extraction to produce biological organic fertilizer for improving soil structure.

Description

(1) Technical field [0001] The invention relates to a method for extracting diosgenin from yellow ginger and pangosaurus and using the waste residue to produce bio-organic fertilizer. (2) Background technology [0002] Turmeric is the rhizome of Dioscorea scutellaria, and Dioscorea chinensis is the rhizome of Dioscorea chinensis, and diosgenin is an important raw material for the synthesis of steroid hormone drugs. Plant saponin cannot be chemically synthesized at present, and can only be extracted from a few plants such as turmeric and pangolin. Turmeric is the plant with the highest saponin content in the world. my country has become a major producer of diosgenin, among which the saponin extracted from turmeric accounts for more than 70% of the total. Because turmeric has good cultivability and is suitable for large-scale planting, it is planted in Shaanxi, Hubei, Hunan, Sichuan, Yunnan, Guizhou and other provinces in China. [0003] Traditional diosgenin extraction tech...
