Problems solved by technology

[0005] In view of the existing defects in the existing tobacco sheet production technology, such as complicated process, high energy consumption, large investment in equipment and space, insufficient curling degree of the produced sheet, poor filling performance, etc., the purpose of the present invention is to provide a method for preparing curls by using low-grade tobacco raw materials. Tobacco flakes with good density, high filling degree, loose structure, and low tar release. This method has short process, simple operation, and low cost. In particular, it does not discharge any industrial pollutants and meets the requirements of industrial production.

Embodiment 1

[0025] The discarded tobacco stems and stem heads produced by the threshing and re-baking factory are pressed into a density of 0.6g / cm with a diameter of 15cm by using a general-purpose tobacco stem and tobacco rod press machine 3 Tobacco material rod round rod; the prepared above-mentioned tobacco material rod is crushed and processed with a general-purpose shavings grinder, and the shavings are sieved to obtain tobacco shavings with a thickness of 0.1-0.4mm, a length of 10-30mm, and a width of 0.5-2mm After the moisture content of the silk is balanced to 12±0.5%, it can be directly used as reconstituted tobacco flakes for cigarette production; the shavings of unsuitable size after sieving are added as raw materials to waste tobacco stems for re-making rods and shavings. The prepared reconstituted tobacco sheet is marked as A.

Embodiment 2

[0027] Fully mix the tobacco powder and bagasse powder produced in the production process of the cigarette factory according to the mass ratio of 5:1, and press it to a density of 1.0g / cm with a diameter of 20cm by using a general-purpose tobacco stem press machine 3 Tobacco material rod round rod; the prepared above-mentioned tobacco material rod is crushed and shavings processed by a general-purpose shavings grinder, and the shavings are sieved to obtain tobacco shavings with a thickness of 0.1-0.3mm, a length of 10-30mm, and a width of 0.5-2mm After the silk balance moisture reaches 12±0.5%, it can be directly used as reconstituted tobacco flakes for cigarette production; the tobacco shavings with unsuitable size after sieving are added as raw materials to the aforementioned mixture to re-make rods and then shavings. The produced reconstituted tobacco sheet is recorded as B.

Embodiment 3

[0029] Spray the tobacco extract on the discarded tobacco stems and stem heads produced by the threshing and redrying factory according to the mass ratio of 0.5:100, and press it into a cross-sectional length and width of 10cm*15cm with a density of 1.3g / cm 3 Tobacco material rod block; the prepared above-mentioned tobacco material rod is crushed and processed with a general-purpose shavings grinder, and the shavings are sieved to obtain tobacco shavings with a thickness of 0.2-0.4mm, a length of 10-30mm, and a width of 0.5-2mm After the moisture content of the silk is balanced to 12±0.5%, it can be directly used as reconstituted tobacco flakes for cigarette production; the shavings of unsuitable size after sieving are added as raw materials to waste tobacco stems for re-making rods and shavings. The prepared reconstituted tobacco sheet is denoted as C.

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...
