Tobacco remanufacturing process by spinning method

Abstract

The invention relates to a tobacco remanufacturing process by a spinning method, belonging to the chemical technology of tobacco, in particular to a tobacco remanufacturing process for remanufacturing the tobacco and tobacco shreds by utilizing smoked sheets, tobacco waste and tobacco stalks. The tobacco remanufacturing process is characterized in that the remanufactured tobacco shreds with different shapes and structures are produced by carrying out the procedures of blending, bulking, grinding, gelatinizing, high-pressure spinning and shred baking on raw materials, and comprise hollow remanufactured tobacco shreds. Compared with the traditional processes such as a thick slurry method, a rolling method and a papermaking method, the tobacco remanufacturing process has the benefits that the utilization ratio of the tobacco is improved from 85%-95% to be close to 100%, no sewage and waste are discharged, the quality of the tobacco shreds is improved, the application range of the remanufactured tobacco shreds is expanded, the process flow is simple and easy to control, the automatic production is easy to be realized and the sensing quality and the production efficiency are improved.

Description

technical field [0001] The invention belongs to tobacco chemical technology, in particular to a process for remaking shredded tobacco by utilizing shredded tobacco sheets, tobacco dust and tobacco stems recovered in the tobacco production process. Background technique [0002] In the process of tobacco processing, such as threshing, redrying, cooling, screening, packing, loose packing, moisture regain, shred drying, shredding, blending, air delivery, wrapping, etc., a large number of broken tobacco pieces and tobacco Tobacco powder, tobacco stems, and the recycling and utilization of these tobacco components in the tobacco industry are important means to improve the utilization rate of raw materials and improve economic benefits. Tobacco, also known as tobacco flakes, for specific technologies, refer to "A Method for Producing Paper-making Tobacco Sheets by Double-wire Method" disclosed in Chinese Patent Application No. 200710034468.2, which discloses a paper-making method f...

AI Technical Summary

Problems solved by technology

[0004] 1. The finished tobacco sheet in the prior art is a large-area sheet whose shape is similar to that of paper and whose thickness is similar to that of natural tobacco leaves. It cannot be directly blended with finished tobacco shreds and rolled into cigarettes directly. It needs to be sorted and processed like natural tobacco sheets. The cutting equipment cuts the tobacco vertically and horizontally into shredded tobacco, and then it can be blended into natural shredded tobacco for use after loosening, regaining moisture, feeding and other processes, and the follow-up process is complicated;

[0005] Second, the existing technology widely adopts the pulping process from the paper industry, which requires time-consuming processes such as immersion defibration and solid-liquid separation for tobacco stems and tobacco powder, and special equipment is required to handle each process. The process is complicated and can High consumption and cost;

[0006] Third, in the prior art, the fibrous material is mainly separated from the tobacco dust and tobacco stems to regenerate the sheet, and the water-soluble substances in the tobacco dust are separated, resulting in sewage discharge, and the screening process will also produce a large amount of waste discharge. environmental pollution;

[0007] Fourth, the existing technology is mainly for large-scale production line applications, and the production capacity is generally fixed at the time of design. For example, the paper-making thin sheet production line produced by the French company Moody is difficult to achieve miniaturized production and capacity expansion on demand;

[0008] Fourth, the sheet produced by the prior art is an imitation of natural shredded tobacco, the product structure and shape are single, and it is difficult to adjust the filling value and combustion characteristics through the shredded tobacco structural design

[0009] Fifth, the flakes produced by the prior art are greatly affected by fluctuations in the quality of raw materials, have a darker color, and have an uncertain taste, so they are rarely used in high-end cigarette products
