Abstract

A method for producing bacterial cellulose by a liquid spraying fermentation tower filled with woven fabric is disclosed. The liquid spraying fermentation tower filled with woven fabric is employed in a fermentation step. The liquid spraying fermentation tower filled with woven fabric comprises a tower body, wherein a return spray plate is disposed on the top portion in the tower body, a woven fabric filling system is disposed on the upper portion in the tower body, a fermentation liquid is disposed on the lower portion of the tower body, and a false bottom is disposed between the filling system and the fermentation liquid. The woven fabric filling system comprises a roller disposed in the tower and woven fabric wound on the roller, one end of the woven fabric is connected with an unreeling apparatus and the other end of the woven fabric is connected with a winding apparatus. The woven fabric filling system is employed and the orientation movement of the woven fabric is utilized, so that Haiyue produced by fermentation production of liquid sprayed vinegar, which means bacterial cellulose and bacterial cellulose membrane system aggregated thereby, is taken away. The method helps to thoroughly solve the problem that the membrane blocks the gaps in the filler and then the fermentation production of vinegar is terminated because of the failure of normal flow of the air and the fermentation liquid.

Description

technical field [0001] The invention relates to the industries and fields of microorganisms, fermentation, textiles, food and beverages, in particular to a method for producing bacterial cellulose with a liquid pouring fermentation tower of woven cloth type filler. Background technique [0002] Cellulose is the most abundant biopolymer with the greatest economic potential on earth. Synthesizing cellulose is not a unique function of plants, some marine organisms can also synthesize animal cellulose, and some bacteria can produce extracellular cellulose more efficiently than plants in a heterotrophic manner. In order to distinguish it from other sources of cellulose, the cellulose synthesized by microorganisms is usually called "Bio-cellulose" or "Bacterial cellulose" (BC for short). Bacterial cellulose belongs to nano-scale fibers and is the thinnest among natural fibers. A typical bacterial fiber line width is only 0.1 μm, while the width of coniferous wood pulp fibers is a...
