Process technique for burley tobacco in blend type cigarette

Abstract

The invention discloses a burley tobacco processing and treating technic in a blended type cigarette. The technic performs a burley tobacco leaf blade making workshop section, a burley tobacco making leaf shred workshop section, and a leaf shred mixing workshop section. The burley tobacco processing and treating technic is used for processing and treating a burley tobacco which is used as an individual formula module in the blended type cigarette, and is impenetrated in the whole process from leaf blade making to leaf shred marking; aiming at the treatment of the material of the burley tobacco, for example, the feed liquid of the burley tobacco is applied by steps and proportion; the baking and the drying of the burley tobacco are performed after cutting shred; the existing burley tobacco baking mode is substituted, a burley tobacco leaf shred baking and drying process mode is adopted, the water ratio and the temperature of the exported leaf shred is fed back and controlled; the processing route of the existing burley tobacco processing technic is changed, a processing technic for shred mixing is adopted. The burley tobacco processing and treating technic can adopt different processing parameters and routes according to the needs of products and different qualities and characters of different burley tobacco raw materials, thus the aesthetic quality of the blended type cigarette is improved, the process flow is simpler, and the processing method is more flexible.

Description

technical field [0001] The invention relates to a tobacco processing technology, in particular to a processing technology of burley tobacco in mixed cigarettes with burley tobacco leaves as an important component. Background technique [0002] Burley tobacco leaves are an important part of the blended cigarette formula. The existing mixed cigarette processing technology is shown in Figure 1, which mainly includes: [0003] Leaf processing section, that is to process the tobacco leaves of Burley tobacco and flue-cured tobacco respectively. Among them, the treatment of Burley tobacco leaves is as follows: slice the tobacco leaves → loosen and rehydrate → store leaves → increase temperature and humidity of Burley tobacco → white Rib tobacco feeding→burley tobacco roasting machine roasting (including three processing stages of drying, cooling and moisture resurgence)→leaf storage, and processing of flue-cured tobacco flakes; [0004] In the cut leaf processing section, the pro...

Problems solved by technology

Invention patent 03126105.1 "Burley Tobacco Sheet Treatment Process" Although two feeding processes are used, they are all carried out in the leaf treatment section

From the point of view of the physical properties of tobacco, compared with filamentous materials, leaf-shaped materials have a smaller specific surface area, a tighter identity, and more waxy chemical components per unit area. In addition, the amount of burley tobacco added is larger. Therefore, during the feeding process, there are many problems such as the difficulty of fully absorbing the feed liquid and uneven feeding.

[0010] (3) In order to make the physical and chemical properties of the cured Burley tobacco sheet meet the task of cigarette processing, the existing Burley tobacco curing machine adopts the "slow roasting" process of drying, cooling, and moisture resurgence. The bad smell that needs to be removed penetrates relatively slowly through the hot and dry air, and the entire treatment time is relatively long, which makes the moisture content of the dried tobacco sheets basically lose, resulting in significantly excessive treatment intensity, resulting in the coking phenomenon of Burley tobacco

[0011] (4) The existing roasting of Burley tobacco slices has disadvantages such as large area of ​​roasting equipment, complicated roasting process, and poor process control accuracy.

During the entire baking process, the material and the conveyor belt remain relatively static, and it is difficult for the material to be heated evenly

In addition, the existing roasting machine manually sets the temperature of each zone to meet the processing method of the moisture content of the roasted tobacco sheets, which makes the response time of the entire moisture control longer and the control accuracy of the moisture content of the outlet tobacco sheets is poor.

[0012] (5) In the existing processing technology, Burley tobacco and flue-cured tobacco leaves are mixed, shredded, and dried. The same processing parameters and the same processing method are used to complete the drying process in one drum, which can easily cause Burley tobacco to be processed. The re-coking phenomenon in the process, and the moisture content of the Burley tobacco component and the flue-cured tobacco component are quite different after drying

[0013] (6) In the existing processing technology, the burley tobacco has not only been roasted with tobacco sheets, but also dried with shredded leaves mixed with burley tobacco and flue-cured tobacco. chemical, processing flexibility is poor
