Two-time cleaning processing method for tobacco stems

Abstract

The invention relates to a two-time cleaning processing method for tobacco stems. The method comprises the steps that the tobacco stems are cleaned for the first time, substances on the surfaces of the tobacco stems and substances influencing the physical quality and sensory quality are removed, and the moisture content of the tobacco stems is increased at the same time; the tobacco stems cleaned for the first time is postprocessed so as to meet the requirement of subsequent processing procedures; the tobacco stems which are cleaned for the first time and postprocessed are cleaned for the second time, and the substances on the surface of the tobacco stems and the substances influencing the physical quality and sensory quality are removed further, and the moisture content of the tobacco stems is further increased at the same time; the tobacco stems cleaned for the second time is postprocessed so as to meet the requirement of subsequent processing procedures. According to the two-time cleaning processing method for tobacco stems, due to the fact that the tobacco stems are cleaned twice, the tobacco stems are further humidified and expanded, moisture is sufficiently absorbed, harmful substances such as chloridion, phenolic substances and water soluble pectin on the surface of the tobacco stems and inside the tobacco stems are further removed, tobacco powder can be removed, and the physical quality and sensory quality of the stem silks are improved.

Description

technical field [0001] The invention relates to the field of tobacco processing, in particular to a method for secondary washing and processing of tobacco stems. Background technique [0002] At present, in the process of developing Chinese-style cigarettes, the tobacco industry is pursuing: "low tar, low harm, high aroma, high quality" as the guide, constantly promoting technological innovation and technological progress, in order to solve the problem of high-quality raw materials, brand expansion, and structural improvement. The existing contradictions require enterprises to study new techniques, technologies and applications of shredded stem processing in combination with product formulas, which will become one of the technical means for enterprises to reduce tar and harm and maintain the individualized quality of Chinese-style cigarettes in the future. Therefore, it is of great significance to improve the quality of cut stems, broaden the scope of use of cut stems, and e...

AI Technical Summary

Problems solved by technology

[0007] 1. In the traditional treatment process, due to the low moisture content of the tobacco stems, the tissue channels have not been opened, and the moisture absorption capacity of the tobacco stems has not been fully utilized. In the process of washing the stems once, the moisture increase is obviously insufficient;

[0008] 2. In the process of washing the stems once, because the tobacco stems do not absorb enough water, they cannot expand quickly. Therefore, the sand and other impurities mixed in the folds of the tobacco stems are not easy to fall off, which affects the ability of the stems to be purified by the washing process. ;

[0009] 3. In the tobacco stem pretreatment section, the unfavorable water-soluble components contained in the tobacco stem are not dissolved and precipitated in time, and it is easy to produce "blade sticking knife" and "filtering on the guide wire groove" in the process of cutting the stem. It not only shortens the service life of the stem cutting machine blade, but also affects the processing quality of the cut stems, such as uneven width of the cut stems, running stems, etc. have a greater impact

[0010] Recently, there have been many innovations in the processing technology of cut stems. Based on recent research and inventions, it has been found that the main methods are to increase the moisture content of tobacco stems for the first time, increase the moisture content of tobacco stems after moisture recovery, increase the strength of dried cut stems, or Tobacco stems are extracted, recombined, and backfilled with feed liquid, and some progress has been made in terms of physical quality and sensory quality, but at the same time, there are also disadvantages such as large energy consumption, complicated process, and high cost.
