Composite reconstituted tobacco sheet, forming device and forming method thereof

Abstract

The invention relates to a composite reconstituted tobacco sheet, a forming device and a forming method thereof. The forming device comprises a conveying device and a left coating roller and a right coating roller disposed under the conveying device, a first tobacco slurry limiting feeding device is arranged on one side of the left coating roller, a second tobacco slurry limiting feeding device isarranged on one side of the right coating roller, peeling devices are arranged under the left coating roller and the right coating roller, and a fiber web is driven by the conveying device to pass through between the left coating roller and the right coating roller, and is subjected to roll compacting through the left coating roller and the right coating roller to form the ribbon-shaped compositereconstituted tobacco sheet covering the fiber web. The tobacco sheet produced by the method has high physical strength and toughness, uniform thickness and good resistance to processing, is not easily broken, and has good flammability and sufficient smoke flavors.

Description

Technical field [0001] The invention relates to a tobacco sheet forming equipment, in particular to a composite reconstituted tobacco sheet forming equipment, as well as its forming method and the composite reconstituted tobacco sheet. Background technique [0002] In tobacco production enterprises, the existing production methods of reconstituted tobacco sheets generally include papermaking, rolling, thick pulping and so on. [0003] The papermaking method is to defibrilize, soak, squeeze and separate tobacco raw materials into tobacco solid fibers and water-soluble separation liquid. The separated tobacco solid fibers are mixed with wood pulp fibers, and a paper-like fiber web is initially formed through sheeting and drying equipment. The separated tobacco soluble separation liquid is formed by reaction concentration and extraction equipment to form a tobacco soluble concentrated liquid, which is mixed with additives to form a coating liquid. The coating liquid forms a "V"-shape...

AI Technical Summary

Problems solved by technology

This method has low investment and low production capacity, and is not suitable for large-scale production.

In this method, the smoke pulp forms a strip-shaped tobacco sheet on the steel strip by smearing. The fibers of the material cannot be effectively arranged, and an interconnected network structure cannot be formed between the fibers. Materials such as fibers and ingredients are bonded together, which is random, resulting in poor density of the finished product and poor thickness uniformity of the sheet. At the same time, due to the high moisture content of the smoke slurry, when the temperature of the steel strip is high, bubbles will be formed, and the bubbles will burst in the sheet. Holes are formed on the surface, affecting the quality of the finished product

In addition, the steel belt drying method is not conducive to the evaporation of moisture in the material, the drying efficiency is low, the production capacity is limited, and the steam consumption is large.
