Problems solved by technology

However, the existing defects are also obvious, that is, it is impossible to eliminate the bottleneck problem of the contradiction between the large volume of raw materials and the small volume of extraction equipment, that is, although the yield has increased, the output has gone up, which is contrary to the company's pursuit of profit maximization. , it is naturally difficult to be accepted by the industry

Embodiment

[0033] The following uses 500L / 40Mpa one-extraction-two-separation cycle supercritical CO 2 Take the extraction device as an example:

[0034] The volume of the extraction kettle is 500L, which can be filled with 300kg of fine powder of hydrolyzate with high content of diosgenin, which is equivalent to 3000kg of dry hydrolyzate of dioscin. After charging is complete, open the CO 2 Put the gas bottle into the cold air tank, turn on the air conditioner to cool the gas tank, open the steam valve to heat the extraction kettle, desorption kettle 1, 2 and separation column respectively, and adjust the set temperature of each container through the steam inlet and outlet valves, that is The temperature of the extraction kettle is 75°C, the temperature of the desorption kettle 1 is 65°C, the temperature of the desorption kettle 2 is 50°C, and the temperature of the separation column is 65°C. After meeting the above temperature setting conditions, start the air high-pressure pump to pr...

Abstract

The invention discloses a method for applying a supercritical fluid extraction device in the diosgenin industry. Firstly, the plant raw material is cut off from excess components and reduced to 9 / 10, so that the content of diosgenin in the hydrolyzed dried product is higher than that of the original plant. The material is correspondingly increased to 9 / 10, so that the extraction and separation equipment is used to increase the extraction function by 9 / 10. The invention eliminates the contradiction between bulky raw materials and narrow and limited space of the extraction container, and simultaneously highlights saponin output and benefit, and the effect is remarkable.

Description

Technical field: [0001] The invention relates to a general preparation of a steroid compound, in particular to an application method of a supercritical fluid extraction device in the diosgenin industry. Background technique: [0002] The chemical name of diosgenin is Δ·3-hydroxyl·25R-helicostene. Because its basic structure is similar to steroid hormone drugs, it is an important starting material for natural and artificial steroid hormone drugs. [0003] Until now, the vast majority of enterprises engaged in the production of diosgenin in my country still use the traditional method that has been used for decades. For example, the roots of Dioscorea genus D. zingibenrnis, also known as turmeric, D. nipponica, and yellow yam (D. panthaica), are washed→broken→powdered→adding acid to heat and hydrolyze→hydrolyze the dry matter→ gasoline extraction method. Although the process is convenient, the yield has remained between 2.0% and 2.5% for a long time, and a large amount of or...
