A microbial fermentation tussah cocoon degumming device

Abstract

The invention relates to a microorganism fermenting tussah cocoon degumming device. The microorganism fermenting tussah cocoon degumming device comprises a cement tank, a stainless steel fence, a heating water tank and a connecting pipeline, wherein the cement tank is used as a fermenting container; the stainless steel fence is used for loading tussah cocoons; the heating water tank is connected with the cement tank through a water pipe; an aeration device is arranged at the bottom part of the cement tank; the side wall of the cement tank is provided with a fermenting liquid inlet and a fermenting liquid outlet for injecting a fermenting liquid; an air blowing pipeline is arranged at the outer wall of the cement tank and is connected with a high-pressure air source of the aeration device.The microorganism fermenting tussah cocoon degumming device has the advantages that the sericin is degraded by protease produced by the microorganism fermenting, and the tussah cocoon degumming effectis good; the design is skillful, the constant temperature can be maintained for fermenting and degumming, and the heating and warming qualities are ensured; the structure is simple, the cost is low,the degumming efficiency is high, and the application prospect is good.

Description

technical field [0001] The invention relates to the technical field of tussah cocoon processing, in particular to a device for microbial fermentation of tussah cocoon degumming. Background technique [0002] Tussah silkworm, belonging to the genus Tussah in the family Lepidoptera, is mainly used for weaving tussah silk. It is one of the unique natural silk fabrics and silk spinning raw materials in my country. Due to the unique luster of tussah silk, its textiles show a natural and luxurious style, and the body feels comfortable and natural, so it is deeply loved by consumers. [0003] The cocoon layer of the tussah cocoon contains 84-85% of water-insoluble fibrous silk protein and 12.10-12.06% of water-soluble globular sericin, and 3-5% of non-protein substances, mainly inorganic salts. , oil, wax and a small amount of tannins, pigments, sugars, etc. The sericin layer surrounding silk fibroin is irregular in shape and is very firmly combined with silk fibroin, while non-p...

AI Technical Summary

Problems solved by technology

The sericin layer surrounding silk fibroin is irregular in shape and is very firmly combined with silk fibroin, while non-protein substances and sericin form insoluble matter, which seriously hinders the penetration of water into the cocoon layer and makes it difficult for sericin to dissolve in water. Swelling and dissolution, making it difficult to loosen tussah cocoons

[0004] The current tussah cocoon degumming technology includes traditional alkaline degumming and enzymatic degumming, but there are certain disadvantages. The traditional alkaline degumming usually uses sodium carbonate boiling degumming method to cause serious pollution to the environment, while the enzymatic degumming method uses a large number of enzymes , resulting in high cost
