A kind of processing technology of thin cigarette

Abstract

A process for processing slim cigarettes, the steps are: loosening and re-moisturizing the tobacco sheet - selecting leaves and removing stems - multi-stage screening and selective cutting - screening and shredding - warming and humidifying the shredded leaves - Feeding of shredded leaves—storage and fermentation—primary drying of shredded leaves—secondary drying of shredded leaves—purification of shredded leaves—scented shredded shreds—rolling. The present invention has the following advantages: adopting the present invention, the tobacco sheet has a high elongation rate, uniform moisture content, and small crushing, and the amount of shredded silk of the cigarette machine is controlled at (25-35)%, the amount of stem removal is controlled at 1.5%, and the draw resistance is controlled ( 1150-1200) Pa, cigarette circumference (17-19) mm, to achieve the effect of full but not empty, uniform and no bamboo.

Description

technical field [0001] The invention belongs to the field of tobacco processing, and in particular relates to a process for processing slim cigarettes. Background technique [0002] The existing flue-cured tobacco leaf processing technology is to unpack, slice, loosen and regain moisture, feed, match leaves and store leaves, shred and dry the tobacco leaves after the initial roasting, after beating, re-roasting, packaging and aging and other processes to make leaf shreds that meet the requirements of the cigarette rolling process. The existing flue-cured tobacco processing technology can meet the requirements of large-scale continuous production of conventional cigarettes (cigarette circumference (24-25) mm), but cannot meet the production requirements of thin tobacco: one is the length of cut tobacco. On the one hand, the reason is that the ratio of large and medium slices is high, resulting in too long length of shredded tobacco, which leads to unstable quality of thin ci...

AI Technical Summary

Problems solved by technology

The existing flue-cured tobacco processing technology can meet the requirements of large-scale continuous production of conventional cigarettes (cigarette circumference (24-25) mm), but cannot meet the production requirements of thin tobacco: one is the length of cut tobacco produced

On the one hand, the reason is that the ratio of large and medium slices is high, resulting in too long length of shredded tobacco, which leads to unstable quality of thin cigarette rolling process, short end and large weight mark. and other unqualified cigarettes, resulting in a large amount of thin cigarette rolling rejections, a high draw resistance standard and a large single box consumption; secondly, due to the high stem content rate in the tobacco leaves, the tobacco stems are shredded during the shredded process. The process forms stems, which are difficult to effectively separate, and the purity of shredded tobacco is not high. During the rolling process of stems, cigarettes enter into cigarettes, causing defects such as puncture and uneven burning of cigarettes, which affect the sensory quality; The width is generally (0.9mm ~ 1.1mm) ± 0.1mm, and the shredded tobacco is too wide to be rolled; the fourth is that the degree of homogenization of the shredded shredded processing is poor (uneven heating during material processing), which affects the sensory quality of shredded tobacco

Existing tobacco sheet loosening and moisture regaining equipment has a tobacco sheet outlet of 55-60±3°C; the leaf storage temperature is 30-40°C, and the shredded leaves are generally dried by drum or air flow, which is difficult to give full play to the advantages of the equipment. Drum drying is beneficial to improve the fragrance permeability, coordination and aftertaste; full-air drying is beneficial to reduce miscellaneous gas ("Tobacco Science and Technology", 2010 No. 2 (Total No. 271), pp. 8-10)
