Burley tobacco strip fuming processing method

Abstract

The invention discloses a burley tobacco strip fuming processing method. The burley tobacco strip fuming processing method comprises the following steps that (1) main veins are removed, and concoction is conducted, wherein the main vein of each burley tobacco leaf collected in a mature state is removed, two half tobacco leaf pieces are obtained, then normal weaving stringing and airing are conducted after folding is conducted, the half tobacco leaf pieces are taken out after a brown changing period is ended, and the main veins are aired independently; (2) segmentation processing is conducted, wherein the burley tobacco half tobacco leaf pieces obtained in the step (1) are stacked neatly, segmentation processing is conducted with 20-30 pieces as a pile, the burley tobacco half tobacco leaf pieces are segmented two times into three pieces which are the leaf tip parts, the leaf middle parts and the leaf base parts; (3) redrying is conducted on the leaves, wherein the segmented tobacco leaf pieces obtained in the step (2) are directly redried, leaf moistening, drying, cooling moisture regaining and packaging are conducted in sequence, and the main veins are redried and packaged independently. The burley tobacco strip processing method is simple in operation technology, easy to implement and capable of being easily transformed into a production line; the technological process is greatly simplified, and the energy loss is obviously lowered; a rib drying period is omitted in the burley tobacco drying stage, the process of cutting for unbinding, picking, leaf beating for stalk removing and the like are omitted in the redrying link, and the production cost of the burley tobacco is lowered.

Description

technical field [0001] The invention relates to the technical field of tobacco production and processing, in particular to a processing method for smoking burley tobacco sheets. Background technique [0002] In recent years, the annual planting area of ​​domestic burley tobacco has reached 30,000 hm 2 It is mainly distributed in Hubei, Sichuan and Chongqing, and a small amount is also planted in Henan and Yunnan. The advantages of Burley tobacco leaves are strong smoke, low sugar content, strong elasticity, and high filling value, but there are also problems such as high nicotine and nitrogen content, slightly bitter smoke, heavy miscellaneous gas, and high irritation. On the other hand, with the continuous improvement of people's living standards, health concerns have increased significantly. Low-tar tobacco products represented by low-harm tobacco products are popular among smokers. In 2013 alone, tobacco products with a tar content of 8 mg or less The volume was 7.3054 ...

AI Technical Summary

Problems solved by technology

Since a complete tobacco leaf is divided into multiple parts such as the tip, the middle and the base of the leaf, there are large quality differences in itself. Therefore, the finished tobacco sheets produced by Burley tobacco have poor quality uniformity and batch-to-batch quality. Defects such as large quality differences between
