Tobacco stem cutting process by threshed tobacco stems

A technology of tobacco stems and shredded stems, which is applied in the field of shredded tobacco stems after threshing, and can solve the problems of large differences in cigarette weight, draw resistance, and density physical indicators, uneven distribution of flaky shredded stems, and large differences in shape of shredded tobacco. To improve the quality and stability of rolling, reduce the re-baking process of tobacco stems, and improve the uniformity of blending

Problems solved by technology

[0006] 3. The tobacco stems of this process cannot be fully softened and restored to the state after the initial roasting when the tobacco is ripe and picked after the second moisture resurfacing and one steaming, which makes the tobacco stems easy to break when pressing the stems, so only "thick pressing" can be used. The gap between the rollers of the stem press machine is generally 1.0-2.5mm. After the subsequent cutting and drying, the shape of the cut stems is mostly flake, which is quite different from the shape of shredded tobacco. The distribution in the strips is uneven, resulting in large differences in physical indicators such as weight, draw resistance, and density of cigarettes after rolling. Usage is limited

Embodiment Construction

[0026] The present invention is described in detail below in conjunction with accompanying drawing technological process as follows:

[0027] Such as figure 2 As shown, the tobacco stem shredded stem processing process after threshing leaves of the present invention is as follows:

[0028] After threshing, the tobacco stems go through the screening process, and after screening out the broken stems with a diameter of φ1.5mm and a length of less than 10mm, the tobacco stems are sent to the soaking device, and the tobacco stems are soaked in circulating hot water at 45-50°C for 3 minutes to wash off the tobacco stems Sand, colloid, hemp silk and other sundries on the surface. Send the soaked tobacco stems to the stem storage cabinet, and store the stems for 2-3 hours, so that the tobacco stems can fully absorb water and fully soften the tobacco stems; meet the needs of thin pressing in the stem pressing process (the thickness of the stems is 0.6-0.8mm ), but in order to reduce...

Abstract

The invention discloses a tobacco stem cutting process by threshed tobacco stems. The process is characterized in comprising the following technical steps: washing stem, storing stem, thinning, cutting stem, carrying out steam explosion for cut stem, drying and so on. The process has the advantages that color and shape of the cut stem processed by the technical method are close to that of the cut tobacco; the breakage rate in the cut stem process is low; the blending uniformity is improved; when smoked, the tobacco is free from harmful wood flavor; the cigarette smoke is harmonized; the comfort of the tobacco is improved; the cut stem is strong in filling capability; and the internal quality of the cigarette is further improved. The power consumption of the corresponding tobacco stem processing enterprise can be reduced. At present, a threshing redrying factory usually stores a lot of tobacco stems, so that the direct stem cutting process provides a new method for comprehensive utilization of the tobacco stems for the redrying factory, and provides a technical economic scheme for forward leading the stem cutting process of a cigarette factory to the redrying factory.

Description

technical field [0001] The invention relates to the technical field of threshing and redrying in tobacco processing, in particular to a shredded process of tobacco stems after threshing. Background technique [0002] At present, the processing process of cut stems in cigarette factories mainly includes: primary rehydration of tobacco stems, storage of stems, secondary rehydration of tobacco stems, steaming of stems (three times of rehydration), pressing of stems, cutting of cut stems, online expansion of cut stems, winnowing, and flavoring etc. (see figure 1 ) process ("Cigarette Process Specification"). There are following deficiencies in the above tobacco stem shredded technology: [0003] 1. This process cannot effectively remove the bad smell such as the essential gas of the cut stems, which makes the difference or inadaptability between the cut stems and the shredded leaves. [0004] 2. The balance between flavoring ingredients and the addition of the cut stems and t...
