Solution Overview
Problem
Existing methods for solubilizing biomass raw materials using heat pulverization require an additional step for extracting water-soluble components, leading to low utilization efficiency.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If heat pulverizing treatment is applied to biomass raw material, then water-soluble components are produced, but an additional extraction step is required reducing utilization efficiency
Solution Approach 1:
The patent combines the pulverizing treatment and water-soluble component extraction into a single integrated process. By controlling particle size to 1 μm or more and 300 μm or less, the pulverized material directly achieves suitable dissolution properties without requiring a separate extraction step, thereby merging two previously distinct operations into one efficient process that improves utilization efficiency while maintaining water-soluble component production
2Ease of operation
If pulverized material particle diameter is reduced to improve dissolution, then handleability and transportability improve, but viscosity increases
Solution Approach 1:
The patent optimizes the particle diameter parameter within a specific range (1 μm or more and 300 μm or less) to achieve the best balance between dissolution performance and suspension viscosity. This parameter control ensures that the pulverized material dissolves easily in water while maintaining suspension viscosity at 2 mPa·s or more and 100 mPa·s or less, thereby improving both handleability and transportability without excessive viscosity increase
