Problems solved by technology

[0005] At present, most of the high-end and slim cigarette raw materials in China are mainly purified by manual leaf selection to reduce impurities and reduce the stalk content in the leaves, but the cost of selection and processing is relatively high

Embodiment Construction

[0022] The present invention will be further described below in conjunction with specific embodiments.

[0023] Experimental site: production line of a rebaking factory

[0024] (1) Before the leaf moistening process, detect the stalk content rate of tobacco leaves of each processing grade. According to the feeding ratio, a total of 7 raw tobacco grades are fed, and 3 secondary finished product grades are formed. According to the stalk content rate 3.0% divide mixed-grade tobacco leaves into three categories, and the specific ratio and stem content are as follows:

[0025]

[0026]

[0027] (2) According to the detection results of the stalk content rate in the leaves of the secondary formula processing grade, combined with the proportion, calculate the compound stalk content rate of the tobacco to be processed.

[0028] After the mixed grades have undergone online selection, leaf moistening, and impurity removal, the leaf threshing process is carried out with reference ...

Abstract

The invention provides a leaf-threshing method for reducing the stalk-containing rate of secondary processed tobacco. The specific steps are as follows: (1) before performing the leaf moistening process, detect the stalk-containing rate of tobacco leaves of each processing grade, and calculate the composite Stem content, mixed grade tobacco leaves are divided into three categories according to stem content <1.8%, 1.8-3.0%, and >3.0%; (2) Mixed grade tobacco leaves are threshed after online selection, moistening and impurity removal After the production line, perform four beatings. Each time the leaf is beaten, it is first determined whether to set the frame according to the different stalks, and then the specific shape and size of the frame and the speed of the beating roller are set. (3) After the leaf beating process, the leaves return normally. Roasting and tobacco stems are collected in separate containers. The invention has the advantages of simple process, reasonable design, strong operability, easy production and implementation, optimizes the structure of tobacco laminae, reduces the intensity of stalking in the cigarette production process, and reduces the loss of shredded tobacco in the process of stalking.

Description

technical field [0001] The invention belongs to the technical field of threshing and redrying of cigarettes, in particular to a threshing method for reducing the stalk content rate of secondary processed tobacco sheets. Background technique [0002] The scale of cigarette development tends to be stable. In order to ensure the steady growth of taxes and profits, it is the general trend to improve the quality and structure of cigarettes. Therefore, the development of cigarettes has higher requirements on the quality of raw materials, especially the rapid development of slim cigarettes, which has higher requirements on the quality of tobacco leaf raw materials. At present, there are two problems in the raw material supply of cigarette industrial enterprises. One is that the grade structure of raw materials in stock cannot meet the needs of cigarette brand structure; needs. Therefore, some industrial enterprises carry out secondary formula processing on raw materials of tobacc...
