Process for paper-making method remade tobacco leaves airflow tobacco shred drying

Abstract

The invention belongs to the technical field of tobacco processing, and particularly relates to a process for paper-making method remade tobacco leaves airflow tobacco shred drying. The process for the paper-making method remade tobacco leaves airflow tobacco shred drying comprises the following steps: resurgence and airflow drying are conducted to remade tobacco leaves after being cut into shreds, and a moisture content of the tobacco shreds is controlled to 23-25%. The process for the paper-making method remade tobacco leaves airflow tobacco shred drying has the advantages of greatly reducing an attrition rate of the paper-making method tobacco leaves in a tobacco shred drying procedure, greatly improving effective utilization, increasing padding values of finished tobacco shreds, improving whole tobacco shred rate, reducing broken tobacco shred rate and tar yield of finished cigarettes, improving cigarette formula integrity, and enabling cigarette sensory quality to be close to a design value.

Description

Technical field [0001] The invention belongs to the technical field of tobacco processing, and specifically relates to a process for air-flow drying of reconstituted tobacco leaves by a papermaking method. Background technique [0002] Paper-making reconstituted tobacco is made by coating concentrated tobacco stalk extracts and additives on a sheet made of tobacco stalks, tobacco stalk fibers and wood fibers, and its structure is made by the action of soluble matter through adhesives Filled in a network structure formed by fibers with a length of about 2mm, it has the advantages of low density, high filling value, and low tar release (only about 50% of tobacco leaves). Reconstituted tobacco leaves are widely used in cigarette leaf formulas, especially in low-grade cigarette formulas. [0003] At present, the domestic low-grade cigarette processing mostly adopts the air-flow drying method in the silk drying process, and uses its high moisture regain and high temperature and high sp...

AI Technical Summary

Problems solved by technology

However, there are the following problems in the treatment of papermaking reconstituted tobacco leaves by the air-dried shredded process of tobacco sheets: the high moisture content dissolves the soluble matter in the filling material of papermaking reconstituted tobacco leaves, the viscosity of the adhesive decreases, and the combination of the filling material and the fiber becomes difficult. If it is too tight, after high-temperature airflow carries high-speed drying, the reconstituted tobacco leaves by papermaking method will produce serious defibrillation and crushing phenomenon, serious loss and greatly reduced effective utilization rate

[0005] In response to this situation, the existing technologies focus on improving the process equipment for the individual shredded or grouped treatment of reconstituted tobacco leaves by the papermaking method, and are limited to the use of traditional drum drying in the shred drying process, and do not involve the use of airflow drying to improve its quality.
