A pretreatment method and pretreatment tool for tobacco leaves before roasting

Abstract

The invention provides a pretreatment method of tobacco leaves before curing. In the pretreatment method, a special main vein removing tool and a special tobacco leaf charging tool are used. The pretreatment method comprises the following operating steps: A, removing main veins of the tobacco leaves by using the main vein removing tool to obtain left half leaves and right half leaves; B, segmenting the left half leaves and the right half leaves into leaf bases, leaf middles and leaf tips by using a carving knife respectively; C, charging the leaf bases, the leaf middles and the leaf tips disorderly by using the tobacco leaf charging tool respectively; D, fixing the leaf bases, the leaf middles and the leaf tips into corresponding boxes by using long needles on the tobacco leaf charging tool respectively. The pretreatment method is simple and convenient to use; by the pretreatment method, the main veins can be quickly removed, segmentation of the leaf bases, the leaf middles and the leaf tips is facilitated, and cell damage during segmentation is avoided; in addition, a way of charging the tobacco leaves into the boxes by class is adopted, and in the curing process, the problem of collapse caused by water loss-type withering of the leaves is solved; through pretreatment before curing, the quality of flue-cured tobacco is integrally improved.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf preparation, and in particular relates to a method for pretreatment of tobacco leaves before roasting and a pretreatment tool thereof. Background technique [0002] There are many factors that affect the quality of flue-cured tobacco. In order to improve the quality of tobacco, it is one aspect to finely control the curing process, and the post-treatment and rolling of curing is another aspect. With the advancement of science and technology, the research to improve the quality of tobacco has been involved in various stages such as self-cultivation, transplanting, picking, pretreatment, curing, and post-treatment. For pre-curing operations, one method is to remove the main veins of the tobacco leaves to improve the quality, and the other method is to clamp and hang the tobacco leaves with tobacco clamps during curing to ensure the gap between the tobacco leaves during curing.

AI Technical Summary

Problems solved by technology

The main defects of this tool for removing the main vein are: 1. Fresh tobacco leaves are cut with gears or with sawtooth, which will cause most of the cells near the cutting line to rupture, and the oxidation of polyphenols is relatively serious, which is not conducive to drying. Formation of quality during roasting

2. When cutting with this tool, you need to press the tobacco leaves by hand, which may easily lead to the problem of tobacco leaves sliding or cutting deviation

3. The efficiency of removing the main artery is low

When curing, the above two tobacco clips or boxing methods (tobacco clips make the tobacco leaves close in the vertical direction, and boxing makes the tobacco leaves close in the horizontal direction). Losing water and withering and collapsing together, resulting in poor ventilation and dehumidification, resulting in poor roasting quality of the cured tobacco
