Abstract

The invention relates to a production technology of pulp, in particular to a technology for producing amygdalus communis peel pulp by using a compound enzyme. According to the technology, lipase, lysozyme, pectinase, feruloyl esterase, aldolase, laccase, xylanase, arabinose isomerase, cellulase and dextranase are mixed into the compound enzyme, and after amygdalus communis peel is subjected to pulping, the compound enzyme is added, and even stirring and mixing are conducted. Then, chlorine is introduced for chlorination, and the pulp is bleached through sodium hypochlorite, subjected to acid treatment through hydrochloric acid, finally conveyed to a concentrator for concentration and then subjected to pulping through a pulper for obtaining the amygdalus communis peel pulp. The obtained amygdalus communis peel pulp is good in quality, high in viscosity, high in polymerization degree, natural and free of pollution, by adding the compound enzyme, interference of hemicellulose, lignin, pectic substances and the like is avoided, and normal operation of the technology is guaranteed.

Description

technical field [0001] The invention relates to a pulp production process, in particular to a process for producing almond peel pulp by using compound enzymes. Background technique [0002] Pulp is a fibrous aggregate obtained by chemically and mechanically treating plant fibers as raw materials. It is a cellulose raw material for man-made fibers. According to the source of raw materials, it can be divided into wood pulp, cotton pulp, bagasse pulp, bamboo pulp, grass pulp, etc. According to different manufacturing methods, it can be divided into pulp made by alkali method, pulp made by kraft method, pulp made by prehydrolysis kraft method, pulp made by sulfite method and pulp made by chlorination method. According to different uses, it can be divided into viscose filament pulp, ordinary viscose short fiber pulp, high-performance viscose fiber pulp, and strong fiber pulp. Pulp quality is closely related to fiber production process and product quality. Important quality in...
