Technology for processing tobacco stalk into shreds

Abstract

The invention provides a technology for processing tobacco stalk into shreds, and belongs to the technical field of tobacco processing. The technology disclosed by the invention has the following steps of: pretreating tobacco stalk, expanding the tobacco stalk with microwave, washing the tobacco with water, storing the tobacco stalk, straightening out the tobacco stalk, slicing the tobacco stalk, charging and storing stalk slices, shredding the stalk slices, drying and shaping the stalk shreds, and perfuming the stalk shreds and storing the stalk shreds. Equipment used in the technology is purchased from the market, wherein the equipment which is purchased from the market, adopts a low-frequency (915MHz) high-power (more than 10kW) microwave magnetron, and transports the tobacco stalk by a belt is improved into equipment which adopts an ultrahigh-frequency (2450MHz) single-pipe low-power (1.5kW) microwave magnetron, performs group control on the microwave magnetron and transports tobacco stalk by a drum. The technology has the characteristics that the tobacco stalk shreds are good in quality consistency and more similar to tobacco leaf shreds in the physical property, and have high sensory quality and filling value; and uniformity, stability and mixing proportion of the tobacco stalk shreds are improved when the tobacco stalk shreds are mixed with the tobacco leaf shreds, the quality of cigarette is improved, the application range and use ratio of the tobacco stalk shreds in the cigarette are improved, and the aims of tar reducing, harm reducing, cost reducing and efficacy enhancing are achieved.

Description

Technical field: [0001] The invention relates to a tobacco stem processing technology, in particular to a tobacco stem filament forming processing technology, which belongs to the technical field of tobacco processing. Background technique: [0002] The existing conventional cut stem processing technology is to cut the tobacco stems into cut stems first, and then puff and dry the cut stems. Cut the shredded stems, expand the shredded stems, and dry the shredded stems. 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 factors cause that the addition rate of cut stems in cigarettes cannot be too high, and most of them are added in cigarettes ...

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 low-frequency (915MHz) high-power (above 10KW) microwave expansion process; The inherent woodiness and miscellaneous smell of silk, the sensory quality of stem silk has not improved much

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 uses low-frequency (915MHz) high-power (above 10KW) microwave magnetrons and belts to transport tobacco stems. , the microwave energy distribution of this equipment is not uniform, and the expansion rate of the prepared tobacco stems is quite different, resulting in inconsistent quality of the cut stems;
