Abstract

The invention relates to a method for correcting the beating degree of tobacco pulp in a pulping process. The method comprises the steps: weighing tobacco raw materials according to the formula of reconstituted tobacco raw materials in the pulping process of reconstituted tobacco pulp, and extracting in a constant-temperature water bath pot by using an aqueous solution for 30 minutes; pulping by a Wali beating machine method and measuring the beating degree by a GB / T 3332-2004 pulp beating degree measuring method and by using a Schober beating degree measuring instrument; measuring the fiber distribution of the pulp by a GB / T 2678.1-1993 paper pulp screening measuring method; establishing a working curve of the beating degree of the tobacco pulp and the 48-mesh passing fine fiber proportion x being more than or equal to 48 meshes, measuring the beating degree of the tobacco pulp DB dryness degree by a dryness degree coefficient method, measuring the fiber distribution of the spin-dried pulp by a paper pulp screening measuring method and measuring the 48-mesh passing fine fiber proportion x dryness degree being more than or equal to 48 meshes; calculating a beating degree correction value by a dryness degree coefficient method; and performing DB correction on the obtained beating degree correction, wherein due to the application of the DB correction, the qualification ratio of the reconstituted tobacco products is increased and the production cost of the reconstituted tobacco is reduced.

Description

technical field [0001] The invention belongs to the technical field of reconstituted tobacco leaf technology, and in particular relates to a method for correcting beating degree in the pulping process of tobacco pulp. Background technique [0002] The results of production practice and literature research show that the current papermaking reconstituted tobacco pulp quality detection method mainly uses the detection method of the paper industry, and the comprehensive quality of the pulp is characterized by the detection results of beating degree and fiber wet weight. Existing literature has focused on the analysis of factors affecting beating quality based on computational science, research work related to pulp quality optimization control; in terms of pulp index detection research, Lai Yanming et al. [13] Researched the use of FS-200 fiber analyzer to measure the fiber length and thickness of several papermaking raw materials and different pulping methods of the same raw mat...
