Method for preparing reconstituted tobacco flakes based on low-grade tobacco raw materials

Abstract

The invention discloses a method for manufacturing recycled tobacco sheet shreds on the basis of low-grade tobacco raw materials. The method includes balancing water in the low-grade tobacco raw materials and compressing the low-grade tobacco raw materials by the aid of rod making machines to obtain compact rods; grinding and processing the rods by the aid of shaving grinders to obtain tobacco shaving; screening the tobacco shaving to obtain the required recycled tobacco sheet shreds. Compared with existing methods for manufacturing tobacco sheets, the method has the advantages that processes are quite simple, the tobacco raw materials can be sufficiently utilized, and accordingly the method is favorable for reducing the cost; the recycled tobacco sheet shreds manufactured by the aid of the method are free of optional substances irrelevant to tobacco, have excellent suction taste and are good in crimp ratio and filling property, and few harmful substances such as tar can be generated when the recycled tobacco sheet shreds are used for tobacco products; requirements on equipment and fields are low, and production procedures are nearly free of pollution.

Description

technical field

[0001] The invention relates to a method for preparing reconstituted tobacco flakes based on low-grade tobacco raw materials, and belongs to the technical field of cigarette production. Background technique

[0002] Tobacco flakes are also known as reconstituted tobacco leaves, reconstituted tobacco leaves or homogeneous tobacco leaves. It is mainly composed of tobacco powder fragments, tobacco stems or low-grade tobacco leaves, plus plant fibers, adhesives and other additives. Reconstituted tobacco leaves have been widely used as raw materials for cigarette products. The preparation of thin sheets by using low-grade tobacco raw materials can make full use of the tobacco raw materials, and can greatly save the production cost of cigarettes. Its preparation methods mainly include papermaking method, thick stock method and roll pressing method. Due to the relatively backward technology of thick stock method and roll pressing method and many reasons of product...
