Independent tobacco cutting process and equipment based on paper making method regenerated tobacco leaf processing characteristics

Abstract

The invention discloses an independent tobacco cutting process and independent tobacco cutting equipment based on paper making method regenerated tobacco leaf processing characteristics. The process comprises the following process steps: opening a box, shoving tobacco leaves, loosening, regaining moisture, cutting, drying and mixing. The equipment comprises a box opening machine, a tobacco leaf shoving machine, a high-frequency-vibrating loosening machine, a moisture regaining machine, a cutting machine and a roller cut tobacco drying machine, wherein the mechanisms can be arranged and can operate alone or in combination through the connection by a material conveying and feeding mechanism. The process and the equipment can cut the boxed regenerated tobacco leaves independently according to the processing characteristics of the boxed regenerated tobacco leaves, thereby improving the effective utilization rate of the paper making method regenerated tobacco leaves, effectively retaining fragrance, improving visual quality, and making the prepared regenerated cut tobacco uniform in length and good in looseness so that the cut tobacco can be blended with other cut tobacco uniformly. The process and the equipment have high adaptability; meanwhile, according to the change in the form of supplied materials, 'three-step method' tobacco cutting adopted in the prior art is changed into one-step cutting with the same effect, the production efficiency is improved and the production cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a process and equipment for making shreds from reconstituted tobacco leaves. Background technique [0002] Paper-making reconstituted tobacco is one of the main raw materials for cigarettes. In recent years, with the expansion of the output of paper-making reconstituted tobacco, the proportion of reconstituted tobacco used in cigarette formula has increased significantly, and the proportion of reconstituted tobacco used in some cigarette brands has reached more than 10%. Since the raw materials used in reconstituted tobacco are mainly leftovers such as threshing and redrying, stems, stems, and tobacco dust in the cigarette production process, and some low-grade tobacco leaves that are difficult to use in formulas, its production and application can effectively improve the comprehensive utilization of raw materials. At the same time, since the physical, chem...

AI Technical Summary

Problems solved by technology

[0003] The existing shredded technology and equipment of reconstituted tobacco leaves by papermaking method mainly have the following deficiencies: ① It cannot be processed according to the processing characteristics of reconstituted tobacco leaves by papermaking method

Compared with natural tobacco leaves, papermaking reconstituted tobacco leaves have great differences in mechanical strength, moisture absorption performance, sensory quality and chemical composition changes during the heating process. When they are mixed with tobacco leaves, the potential and use value of papermaking reconstituted tobacco leaves are not obtained. Fully play, thus affecting the silk quality and product quality

② Poor shred quality

Because the reconstituted tobacco leaves of the papermaking method contain a certain amount of wood pulp fibers, and their tensile strength and shear strength are relatively high, the existing shredding machine is difficult to meet the needs of shredding the reconstituted tobacco leaves separately, and can only be shredded after being mixed with the tobacco leaves. The blending ratio is generally below 20%

Due to its high strength, it is difficult to cut, and it is easy to produce "running film" during the shredding process, which affects the uniformity of shredded width

③The processing intensity of reconstituted tobacco leaves by papermaking method is high in the silk making process

At present, the reconstituted tobacco leaves are processed together with the tobacco leaves by the papermaking method, and the processing intensity is set according to the processing characteristics of the tobacco leaves. It does not fully consider that a series of soaking and drying processes have been carried out in the production process of the reconstituted tobacco leaves. The processing characteristics of low temperature and low moisture content are required in the silk process, resulting in a large loss of aroma and poor sensory quality during the silk making process

④The effective utilization rate of reconstituted tobacco leaves is low

The reasons: First, when the moisture content of the reconstituted tobacco leaves is too high, the strength of the reconstituted tobacco leaves is significantly reduced when the papermaking method is mixed with the tobacco leaves, and it is easy to cause chipping.

Second, liquid water is applied to the reconstituted tobacco leaves by the papermaking method together with the tobacco leaves during moisture regain. Due to its different tissue structure from tobacco leaves, fast moisture absorption rate and poor water holding capacity, the local moisture content is too high, resulting in the strength of this part of the reconstituted tobacco leaves becoming weaker. Difference

This method attempts to change the existing problems in the manufacture and production of reconstituted tobacco leaves by the existing papermaking method, but there are still the following deficiencies: ① no specific process and equipment are proposed to solve the problem of shredded and blended reconstituted tobacco leaves; ② lack of separate shreds the specific way

However, the existing techniques and equipment for making shreds such as loosening, regaining moisture, and shredding of laminar tobacco cannot meet the needs of making shredded reconstituted tobacco leaves.
