Fermentation compounding device for microbial cellulose and base material and technology of fermentation compounding device

Abstract

The invention provides a fermentation compounding device for microbial cellulose and a base material. The fermentation compounding device is provided with a base material unwinding device, an introducing roller, a fermentation compounding box, clamping rollers, a drying inactivation device and a compound coil winding device in sequence in the base material walking direction. Mixed paste of a microbial strain and cellulose stoste is stored in the fermentation compounding box, the base material is pulled to pass through the mixed paste in the fermentation compounding box, and microbial cellulose filaments excreted by microorganisms are uniformly deposited on the surface of the base material to form a compound product. The base material is paper made of plant long fibers or cotton or hemp or chemical fiber yarns or non-woven cloth or woven cloth made of cotton or hemp or chemical fiber yarns. The compounding box is connected with a temperature control device, a vibration device and the like. The microbial cellulose is densely deposited on the base material with a uniform deposition thickness, and the fermentation compounding device is suitable for large-scale production work. The obtained product has excellent mechanical properties, elasticity and water resistance.

Description

technical field [0001] The invention relates to a composite technology of microbial cellulose fiber and other materials. Background technique [0002] Through the biochemical reaction of microorganisms such as bacteria and chemical reagents on plant materials, cellulose fiber materials can be obtained after certain conditions and processes. [0003] The invention with application number 201010142735X relates to a method for producing bacterial cellulose by using wheat straw / rice straw, including: (1) grinding wheat straw or rice straw, then soaking with dilute sulfuric acid or hydrochloric acid, reacting, and then filtering the wheat straw Or the rice straw residue is separated from the acid hydrolyzate, and the hydrolyzate is collected for subsequent use; (2) the detoxification of the hydrolyzate; (3) the above-mentioned detoxified hydrolyzate is taken as the carbon source of the culture medium, and the nitrogen source is added to form a culture medium, which is inserted in...
