Aerosol-Generating Sheet Formulation Without Extract Concentration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing aerosol-generating sheets using tobacco extract require concentration steps, which can lead to inefficiencies and loss of flavor components.
Innovation Solution
A production method that maintains a liquid-solid ratio of at least 3 in the mixture of tobacco extract and other ingredients, allowing for the preparation of sheets without concentration, thereby preserving flavor components and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the sheet composition is concentrated to produce aerosol-generating sheets using tobacco extract, then the sheet can be produced, but the production process becomes less efficient and flavor components are lost
Solution Approach 1:
The invention changes the critical parameter of liquid-solid ratio in the sheet composition. By maintaining a liquid-solid ratio of at least 3 (weight of water/weight of non-water ingredients), the patent enables direct sheet production without concentration, thereby improving production efficiency and preserving flavor components that would otherwise be lost during concentration processes
2Ease of manufacture
If the liquid-solid ratio is maintained at least 3 in the mixture, then sheets can be produced without concentration, but the mixture composition becomes more specific
Solution Approach 1:
The invention establishes a clear parameter threshold (liquid-solid ratio ≥ 3) that simplifies the manufacturing process by eliminating concentration steps. This parameter requirement, while specific, provides a straightforward guideline for formulation that actually reduces processing complexity compared to multi-step concentration and dilution processes
