Raw materials for cigarettes, production method and equipment thereof

Abstract

The invention provides raw materials for cigarettes, a production method of the raw materials for the cigarettes and equipment of the raw materials for the cigarettes. The production method of the raw materials for the cigarettes includes the following steps. Firstly, plant biomass is heated and moistened unit the water content reaches 35 wt% to 40 wt%. Secondly, materials are preheated after being heated and moistened until the water temperature of the materials reaches the boiling point. Thirdly, the preheated materials are expanded with micro waves until the water content reduces to 10 wt% to 20 wt%. Fourthly, water is added to the materials until the water content reaches 30 wt% to 40 wt%. Fifthly, the materials are machined to be fiber shreds. Sixthly, biological enzyme liquid is sprayed onto the fiber shreds, the fiber shreds with the biological enzyme liquid are soaked in water. Seventhly, drying is performed. The raw materials for the cigarettes, the production method of the raw materials for the cigarettes and the equipment of the raw materials for the cigarettes overcome defects in the prior art, have the advantages that water consumption in production is low, crushed raw materials for the cigarettes obtained in production are less, compatibility with tobacco shreds is perfect, woodiness texture is not obvious and can be applied to manufacture of high-grade cigarettes.

Description

technical field [0001] The invention relates to tobacco technology, in particular to a tobacco raw material, its production method and equipment. Background technique [0002] Tobacco raw material is a kind of material prepared from biomass such as tobacco stems and straws, which can be used to replace part of shredded tobacco leaves and added to cigarettes to reduce the cost of cigarettes and the tar content of cigarettes. Although the application level of tobacco raw materials in cigarettes has been continuously improved in recent years, there are still many problems, so that they can only be added in a small amount in low-grade cigarettes, but cannot be added in high-grade cigarettes. The following will be described in detail by taking tobacco stems as an example to prepare raw materials for tobacco. [0003] Tobacco stems are the companions of tobacco leaves, and are widely used in the production of low-grade cigarettes because they have very similar components to tobac...

AI Technical Summary

Problems solved by technology

Although this method can give full play to the advantages of microwave expansion to a certain extent, there are still many shortcomings: the moisture content of the tobacco stems before microwave treatment is low, which does not conform to the basic principle of microwave expansion, and the internal structure of the tobacco stems after microwave treatment is easily destroyed. Even coking or igniting; the shredded tobacco stems prepared by this method are prone to breakage in the shredding process; the problems caused by woody gas and green miscellaneous gas are still relatively prominent, which limits their addition in cigarettes, and almost Both are added to the cigarettes of the third and fourth types of...
