Embodiment 1

[0048] Take 1890kg raw hemp and install them into three hemp cages. Firstly, 0.15m 3 Inject the first and second level culture bacteria liquid into the fermentation pot and mix with 5 tons of warm water that has been adjusted to 32℃ in the fermentation pot, add the culture medium, and CO(NH2) 2 3-15kg, KCL3-15kg, then add compressed air 0.12m 3 / h, then 630kg / cage raw hemp that has been installed in the cage is hoisted into the fermentation pot and fermented in a water bath at a temperature of 32-35°C for 6-12 hours. After 6-12 hours, take out the first cage of hemp, and then hoist 630kg / cage of raw hemp in the new cage, and ferment the second cage of raw hemp for another 6-12 hours; then hoist the third cage of hemp and repeat the above operation until Fermentation of hemp in the third cage is completed (1890kg raw hemp is completely fermented).

[0049] After the third cage hemp is lifted out, the fermentation liquid in the fermentation pot is heated to 80-90°C for sterilization...

Embodiment 2

[0052] Take 1800kg of raw hemp and add 0.13m 3 The culture solution is poured into the fermentation pot and mixed with 6 tons of warm water at 33℃ in the fermentation pot, and 6kg CO(NH2) is added. 2 With 6kg KCl, plus compressed air 0.15m 3 / h, then hoist the caged raw hemp into the fermentation pot for water bath fermentation for 10 hours.

Embodiment 3

[0054] Take 1620kg of raw hemp and add 0.15m 3 Inject the culture broth from the fermenting pot with 6 tons of warm water at 32.5℃ that has been adjusted in the fermenting pot, add 4kg CO(NH2) 2 With 4kg KCl, plus compressed air 0.1-0.2m 3 / h, then hoist the caged raw hemp into the fermentation pot for 6 hours of water bath fermentation.

[0055] Preferably, CO(NH2) 2 Compared with KCL, the ratio is 0.5-2% of raw hemp.

Abstract

The invention relates to the field of processing ramie, particularly a process and a device for water-bath continuous fermentation of biologic degumming fibrilia. By using the process and the device, the problems of the prior art that the output of ramie production is low, the energy consumption is high and the product quality is unstable are solved. The process comprises the following steps: placing strain into a fermentation pan; adding water and mixing; adding carbon source and nitrogen source; continuously filling compressed air; and suspending a caged raw ramie into the fermentation pan so as to perform the water-bath fermentation. The invention provides the process and the device for water-bath continuous fermentation of biologic degumming fibrilia, through which the process flow is shortened, the fermentation effect is stable, the construction structure is simple, the operation is convenient and the running cost is low.

Description

Technical field [0001] The invention relates to the field of ramie processing, and is a continuous fermentation process and equipment for biological degummed hemp fiber in a water bath. Background technique [0002] Ramie, jute, kenaf and other types of hemp fibers must be spunable fibers to remove the pectin, hemivitamin, lignin, ash and other components in the fibers through a series of degumming processes to extract spinnable fibers. [0003] The traditional degumming process basically uses a large amount of chemical raw materials such as caustic soda, sulfuric acid, sodium hypochlorite, water glass, etc., using high temperature and high pressure cooking. Due to the use of chemical raw materials, on the one hand, a large amount of industrial polluted wastewater is caused by the degumming process. The CODcr content in the discharged wastewater is as high as about 16000 mg / L, which brings difficulties to corporate wastewater treatment and increases corporate wastewater treatment c...
