Tobacco sheet for electronic cigarette and preparation method thereof

Abstract

The invention provides a method for preparing tobacco sheet used in electronic cigarettes. The specific steps are as follows: 1) paper-making the base material of tobacco sheet; Formulated into a high-concentration coating solution; 3) Formulating tobacco flavors, smoking agents, etc. , suspended and dried; 5) peel off the dried tobacco sheet from the PET film, and carry out rolling compounding with the tobacco sheet substrate; 6) dry the composited tobacco sheet, and spray the smoking preparation on the tobacco sheet ; 7) After soft pressing with soft pressing rollers, the thin slices are peeled off and sliced ​​to obtain tobacco thin slices for electronic cigarettes. The invention adopts high-concentration coating flexible transfer molding technology, and the prepared tobacco sheet product has uniform raw materials and good quality, and greatly reduces energy consumption in the drying process, is easy to operate, and is suitable for industrial continuous production.

Description

technical field [0001] The invention relates to the technical field of tobacco sheets, in particular to a method for preparing sheets for electronic cigarettes. Background technique [0002] In recent years, Philip Morris International has developed iQoS, a heat-not-burn tobacco product, and PAX Labs, an electronic cigarette company, has developed Juul products. [0003] In June 2015, Philip Morris International applied for the patent "Reconstituted Tobacco Sheet and Related Methods", which uses the thick pulp method to mix the deflated tobacco stem refined fiber with tobacco powder and additives to form a slurry, and casts to prepare the regenerated tobacco sheet . The method is simple, easy to operate, and the product is evenly mixed, but the strength of the prepared tobacco sheet is too low, which is not conducive to winding, and at the same time consumes a lot of water and increases energy consumption. [0004] In May 2018, China Tobacco Hubei's patent "A Preparation M...

AI Technical Summary

Problems solved by technology

The number of rolling presses increases, the energy consumption increases, the product has low flexibility, fragility, poor color, insufficient smoke aroma, small amount of smoke, and unsatisfactory taste

[0005] In August 2018, China Tobacco Yunnan Co., Ltd. patented "A dry-process reconstituted tobacco leaf for heat-not-burn cigarettes and its preparation method", which mixes tobacco powder with binder, smoker, sugar and flavoring substances The coating solution is coated on the fiber thin-layer substrate prepared by the dry method for multiple times, and after calendering, the reconstituted tobacco leaves of heat-not-burn cigarettes are prepared. The steps are repeated many times, the production process is complicated, the energy consumption is large, and the fiber thin layer substrate is easy to break, and the degree of adhesion to the steel belt is poor, and the operation is difficult, which affects product quality and production efficiency

[0006] To sum up, in the preparation process of the above heat-not-burn tobacco sheet, the rolling method is adopted, the process is complicated, the product has low flexibility, fragility, poor color, insufficient smoke aroma, small amount of smoke, and unsatisfactory taste

Using thick slurry method, the energy consumption is high in the drying process, the substrate is easy to break during the coating process, the adhesion between the substrate and the steel strip is poor, and the operation is difficult, which affects product quality and production efficiency. The product has low tensile strength and is not conducive to winding. , not conducive to industrial continuous production
