Embodiment 1

[0030] refer to figure 1 , a process for the purification of fermented Cordyceps powder, using 100kg of fermented Cordyceps powder with a solid content of 26.7wt% as raw material for purification, using a ceramic membrane with a filter aperture of 600nm as the microfiltration membrane, and a ceramic membrane with a filter aperture of 300nm As an ultrafiltration membrane, the purification process includes the following steps:

[0031] S1. Cleaning steps:

[0032] S11, clean the microfiltration membrane and ultrafiltration membrane with tap water until the cleaning solution is clear, then wash with lye, the lye is a mixed solution of NaOH and NaClO, wherein the concentration of NaOH is 1wt%, and the concentration of NaClO is 0.5wt% , controlling the temperature of the lye to be 60°C, and the alkali washing time to be 30 minutes, to obtain an alkali-washed microfiltration membrane and an alkali-cleaned ultrafiltration membrane after washing; collect the alkali wash solution into...

Embodiment 2

[0044] This embodiment is basically the same as Implementation 1, the difference is:

[0045] Purify with 100kg of fermented Cordyceps powder with a solid content of 31.2%;

[0046] The concentration of NaOH in S11 is 1.5wt%, the concentration of NaClO is 0.7wt%, the temperature of the lye is 605°C, and the alkali washing time is 25min.

[0047] HNO in S12 3 The concentration is 1wt%.

[0048] The microfiltration membrane in S21 is a ceramic membrane with a filter pore size of 500nm, and the ultrafiltration membrane in S22 is a ceramic membrane with a filter pore size of 200nm.

[0049] Finally, 30.76 kg of fermented Cordyceps powder was obtained, and the solid recovery rate was 98.6%.

Embodiment 3

[0051] This embodiment is basically the same as Embodiment 1, the difference is:

[0052] Purify with 100kg of fermented Cordyceps powder with a solid content of 34.5%;

[0053] The concentration of S11NaOH is 2wt%, the concentration of NaClO is 1wt%, the temperature of the lye is 70°C, and the alkali washing time is 20min.

[0054] HNO in S12 3 The concentration is 1.5wt%.

[0055]The microfiltration membrane in S21 is a ceramic membrane with a filter pore size of 450nm, and the ultrafiltration membrane in S22 is a ceramic membrane with a filter pore size of 150nm.

[0056] Finally, 34.12 kg of fermented Cordyceps powder was obtained, and the solid recovery rate was 98.9%.

Abstract

The invention discloses a purification process for fermentative cordycepic fungal powder. The purification process comprises the following steps: S1, cleaning which includes alkali washing and acid pickling; S2, filtering which includes micro-filtration membrane filtering, ultrafiltration membrane filtering and filtrate processing; S3, drying; and S4, milling which includes grinding and sieving to obtain a finished product. The purification process for the fermentative cordycepic fungal powder has the characteristics of environmental protection and secondary pollution avoidance, the yield of solid content of the fermentative cordycepic fungal powder in the prepared finished product is higher than 98%, and the problems of low yield of solid content of the fermentative cordycepic fungal powder and high probability of environmental pollution in the prior art are solved.

Description

technical field [0001] The invention relates to a preparation process of fermented Cordyceps powder, in particular to a purification process of fermented Cordyceps powder. Background technique [0002] Cordyceps sinensis is a unique product of the plateau at an altitude of 3,000 to 5,000 meters. The market supply is limited and a large number of substitutes are needed, and artificially fermented Cordyceps fungus powder is one of the main substitutes. Although the fermentation capacity of Cordyceps fungus powder is large, its extraction process is outdated. At present, the method of plate and frame filtration is mainly used to separate the solid and liquid of the fermentation liquid. This separation method consumes a lot of energy, and the installation and disassembly of the plate and frame cloth is difficult, requiring a lot of labor. The operation is not easy to automate, the processing capacity is limited, and the maintenance is difficult, and the filtrate contains a large...
