Tobacco stem pressing and shredding technology

Abstract

The invention discloses a tobacco stem pressing and shredding technology and belongs to the technical field of tobacco processing. The technology comprises the steps of conducting high-temperature high-pressure and decompression preprocessing on tobacco stems, conducting microwave expansion on tobacco stems, humidifying and storing tobacco stems, heating and humidifying tobacco stems, pre-pressing tobacco stems, conducting secondary stem pressing, conducting ternary stem pressing, feeding stems, shredding stems, shaping and drying stem shreds, and perfuming and storing stem shreds. The technology has the advantages that the quality consistency of stem shreds is good, the physical property of stem shreds is closer to that of leaf shreds, organoleptic quality and padding value are high, the uniformity, stability and blending ratio of stem shreds blended with leaf shreds are improved, cigarette quality is improved, the application range and utilization rate of stem shreds in cigarettes are increased, and tar reduction, harm reduction, cost reduction and benefit increasing are realized.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of tobacco processing, and relates to a tobacco stem processing technology, in particular to a tobacco stem pressing and shredding processing technology. [0003] Background technique: [0004] The existing conventional tobacco stem processing technology is to cut the tobacco stems into shredded stems first, and then puff and dry the shredded stems. Cut stems, high temperature and high humidity, drying and setting, flavoring, blending into shredded tobacco, the technological process, see the attached figure 1 . The physical properties of the shredded stems are quite different from those of the shredded leaves. The woody gas and green miscellaneous gas produced by combustion are relatively large, and the uniformity of blending with the shredded leaves is poor. The physical indicators of the rolled cigarettes fluctuate greatly, which also affects the quality of cigarettes sensory quality. These f...

AI Technical Summary

Problems solved by technology

The problems in this patent are: ① cut the tobacco stems into slices with a thickness of 0.12-0.3mm, and then expand them at high temperature. At this time, the stem slices are thin and the expansion rate of the stem slices is not high; Low, high crushing rate; ③ The woody gas and green miscellaneous gas of the finished stem shreds are relatively large

The problem that this patent exists is: 1. the expanded tobacco stem of expansion degree more than 150% adopts the process method disclosed by the patent No. ZL03117228. It is replaced by the existing high temperature and high pressure expansion process or the microwave expansion process with low frequency 915MHz and high power above 10KW; The sensory quality of shredded stems has not been greatly improved

The problems in this patent are: ①The expansion of tobacco stems is obtained by using existing microwave expansion equipment, while the existing microwave expansion equipment adopts a low-frequency 915MHz high-power microwave magnetron and a belt to transport tobacco stems. The distribution of microwave energy is not uniform, and the expansion rate of the prepared tobacco stems is quite different, resulting in inconsistent quality of the cut stems;

The problems in this patent are: ①The tobacco stems are sliced ​​and then cut into shreds, the shredded stems are relatively high, the rate of filaments is low, and there are many short shreds, which affect the uniformity of blending with shredded tobacco; ②Because of the high shreds, In the subsequent shaping and drying process, its processing strength is low, which affects the curling degree and filling ability of cut stems
