Tobacco stem processing system and method

Abstract

The invention discloses a tobacco stem processing system and method, and relates to the field of reconstituted tobacco processing. The system and method are used for improving the tobacco stem swelling effect. The tobacco stem processing system comprises an electronic scale and a processing part. The processing part is provided with a containing cavity for a to-be-processed product and an air hole communicated with the containing cavity. High-temperature and high-humidity air can enter the containing cavity through the air hole. According to the technical scheme, steam is introduced from the bottom of a drying tunnel vibration groove and makes full contact with tobacco stems so that the water content of tobacco stems can be uniform and fiber structures can sufficiently swell. By means of the technology, washed tobacco stem raw material is processed at high temperature and high humidity, water can be uniformly absorbed by the tobacco stem raw material, tobacco stem fiber sufficiently and uniformly swell, the stable raw material is provided for the subsequent extracting and pulping procedures, the wet weight of pulp is increased, the stability of the solid content of stem paste concentrate liquid is improved, and high production and application value is achieved.

Description

technical field [0001] The invention relates to the field of reconstituted tobacco leaf processing, in particular to a tobacco stem processing system and method. Background technique [0002] Paper-making reconstituted tobacco is a new type of tobacco manufacturing technology widely used by domestic sheet companies. It mainly uses tobacco stems and some low-grade tobacco leaves as the main raw materials, and undergoes pretreatment, extraction, pulping, papermaking, coating, drying and other processes. , to make tobacco flakes whose sensory quality and shape are close to or even better than natural tobacco leaves. Tobacco stems are an important part of the raw material of reconstituted tobacco leaves. In the production process of reconstituted tobacco leaves by papermaking method, the stem washing process is very important. This process generally uses circulating hot water soaking method, which is mainly used to remove dust, gravel and other impurities attached to the surface...

AI Technical Summary

Problems solved by technology

The traditional tobacco stem treatment is to wash the stems and directly use them for extraction and pulping. However, the tobacco stems used for reconstituted tobacco leaves are first mixed with the new stems of the current year and the aged tobacco stems stored in different origins and years. After washing the stems, the traditional method ignores the difference between the new tobacco stems and the aged tobacco stems. Due to the low moisture content of the aged tobacco stems and the dehydration of the skin cell wall of the stems is more serious than that of the new tobacco stems, the wall layer is dense and hard, and it is not easy to absorb water. Washing stems can only remove stains and sediment on the surface of the tobacco stems, but cannot allow moisture to fully enter the interior of the tobacco stems. The swelling of the fibers is not sufficient, resulting in varying degrees of moisture and swelling in the tobacco stems after washing, and it is impossible to achieve "homogeneous". Extraction" and "Flexible Pulping" effects

[0004] At present, the domestic reconstituted tobacco industry has not taken effective processing measures for the washed tobacco stems, so that the tobacco stem fibers can be fully and uniformly swelled before extraction
