Tobacco Rolled Sheet Formation Without External Plant Fibers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing tobacco sheets require the external addition of poorly water-soluble substances like plant fibers, which increases costs and processing time, and there is a need for a method to form tobacco sheets without such external additives.
Innovation Solution
A rolled sheet is formed using a tobacco raw material that includes a poorly water-soluble substance derived from the tobacco itself, combined with starch extracted from the tobacco raw material, without the need for external additives like plant fibers, through a process involving heating and extraction of starch from the tobacco raw material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If external additives like plant fibers are added to improve sheet formability and strength, then the sheet strength and formability are improved, but the manufacturing cost and processing time increase
Solution Approach 1:
The tobacco raw material itself serves the dual function of providing structural framework and binding agents. The naturally occurring cellulose fibers in tobacco leaves provide the sheet structure, while starch granules act as binders, eliminating the need for external additives like plant fibers or synthetic binders.
Solution Approach 2:
The invention changes the particle size parameters of tobacco materials to optimize sheet formation. By controlling the particle size distribution of tobacco leaves and starch granules, the sheet achieves proper formability and strength without requiring external additives.
2Strength
If external additives like plant fibers are added to improve sheet formability and strength, then the sheet strength and formability are improved, but the processing time and labor increase
Solution Approach 1:
The tobacco raw material itself serves the dual function of providing structural framework and binding agents. The naturally occurring cellulose fibers in tobacco leaves provide the sheet structure, while starch granules act as binders, eliminating the need for external additives like plant fibers or synthetic binders.
3Strength
If tobacco particle size is reduced to increase surface area and bond strength, then the sheet strength is improved, but the manufacturing complexity increases
Solution Approach 1:
The invention changes the particle size parameters of tobacco materials to optimize sheet formation. By controlling the particle size distribution of tobacco leaves and starch granules, the sheet achieves proper formability and strength without requiring external additives.
