Single shred making process suitable for paper-making process reconstituted tobacco manufacturing plant

Abstract

The invention relates to a single shred making process suitable for a paper-making process reconstituted tobacco manufacturing plant. The single shred making process includes the following steps: (1) storage, (2) shred cutting, (3) feeding, (4) temporary storage, (5) temperature and humidity increasing, (6) shred drying, (7) purification and (8) blending. Single shred making is achieved for processing characteristics of paper-making process reconstituted tobacco leaves, the process is concise, the energy consumption is low, dust in the production environment is small, the peculiar smells are fewer, the width and the length of reconstituted tobacco shreds are even, the reconstituted tobacco shreds are good in friability and high in effective using rate, fragrance of the reconstituted tobacco leaves is effectively kept, and the sensory quality is improved.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a separate silk-making process suitable for a papermaking reconstituted tobacco leaf production plant. Background technique [0002] The existing paper-making process of reconstituted tobacco leaves is to soak and extract tobacco raw materials such as tobacco stems, tobacco powder and shredded tobacco sheets, and then separate the soluble matter from solid-liquid; Once dried, the soluble matter is concentrated and coated on the fiber sheet, and then dried twice. The dried banner-shaped reconstituted tobacco leaves are dried again after being sliced, and finally packed into boxes. During the cigarette production process, it is co-processed with natural tobacco leaves to make shredded tobacco according to the product formula design ratio. [0003] Reconstituted tobacco leaves by papermaking method have the following characteristics: ①The tissue structure of ...

AI Technical Summary

Problems solved by technology

[0004] ②The shear strength and tensile strength of reconstituted tobacco leaves by papermaking method are quite different from those of tobacco leaves. Tobacco leaves are easy to run out when cutting shreds, which requires a high knife door pressure, resulting in poor looseness of the cut tobacco, which affects the moisture uniformity of the dried cut outlet. And the uniformity of its distribution in cigarettes, which ultimately affects the quality stability of cigarettes

[0005] ③The existing papermaking process for reconstituted tobacco shreds is mixed with tobacco leaves to make shreds. The processing flow, parameters and equipment cannot be processed according to the characteristics of reconstituted tobacco leaves, and the processing conditions cannot effectively exert the potential and use value of reconstituted tobacco leaves. , the aroma loss of reconstituted tobacco leaves after silk processing is relatively large, and the sensory quality is generally deteriorated

[0006] ④ The effective utilization rate of reconstituted tobacco leaves is low (according to production tests, the effective utilization rate of reconstituted tobacco leaves in the cigarette production process is mostly below 90%, and the effective utilization rate of tobacco leaves has reached 93%)

The first reason is that after moisture regain, feeding and drying in the silk making process, some fibers are separated from the reconstituted tobacco leaves and become "flying fibers" and tobacco dust, which not only affects the utilization rate of reconstituted tobacco leaves and the production efficiency of cigarette machines, but also " The diffusion of "flying fiber" in the air has also caused environmental pollution; the second is that there are many filaments, drawing frames, and running sheets in the reconstituted tobacco after shredding. The silk flicking roller of the cigarette machine is loose, causing some agglomerated filaments and drawing strips to be removed by the cigarette machine; third, due to the poor hygroscopicity of the reconstituted tobacco leaves, in order to meet the technical quality requirements of the tobacco leaves in the process of rehydration, feeding and drying, etc., reconstituted tobacco leaves The moisture content of the reconstituted tobacco leaves is lower than the technical requirements of each process, resulting in the crushing of the reconstituted tobacco leaves during the silk making process, which is screened out by the screening link in the silk making process or sucked away by the dust removal system

Fourth, with the application of group processing technology for branded cigarettes, the existing sheet blending technology has been difficult to meet product design and processing requirements

[0011] The above disclosed patents have a certain similarity, all of which are unpacking, loosening, rehydration, shredding, drying and blending of reconstituted tobacco leaves in boxes, although they better solve the problem of co-processing of reconstituted tobacco leaves and natural tobacco leaves in the papermaking method. , dust, flying fiber, utilization rate, etc., but there are still the following problems: (1) The process of making reconstituted tobacco leaves is complex, requiring unpacking, metering, loosening, and moisture resurgence, which consumes a lot of energy and requires a lot of investment; (2) ) Tobacco particles and fibers on the surface of reconstituted tobacco leaves are easy to fall off during the process of unpacking, loosening and regaining moisture, resulting in dust and flying fibers, resulting in poor environment and reduced utilization rate; Volatilization, resulting in loss of aroma; (4) The reconstituted tobacco was not considered and the liquid suitable for the cigarette brand was not added, resulting in a change in the quality of the reconstituted tobacco after blending

Based on the above reasons, the above patents are difficult to be applied in production
