Fibrous Dextrin Particles for Moisture Dispersibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current thickeners containing dextrin particles prepared by the spray dry method have poor dispersibility in moisture, making them less effective in preventing aspiration during swallowing disorders, while those prepared by the drum dry method are expensive.
Innovation Solution
Preparation of fibrous dextrin particles through spray drying a highly viscous dextrin solution, which improves the dispersibility of thickeners in moisture, reducing production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dextrin particles are prepared by the drum dry method, then dispersibility in moisture is improved, but production cost increases
Solution Approach 1:
The invention changes the key parameter of solution viscosity to a specific range (10-1000 mPa·s) to enable spray drying to produce particles with fibrous morphology that achieves dispersibility comparable to drum-dried products. This parameter optimization allows the use of the cheaper spray drying method while maintaining the dispersibility performance previously only achievable through expensive drum drying.
2Ease of manufacture
If dextrin particles are prepared by the spray dry method, then production cost decreases, but dispersibility in moisture deteriorates
Solution Approach 1:
The invention optimizes the viscosity parameter of the dextrin solution within a specific range (10-1000 mPa·s) before spray drying. This parameter control transforms the spray-dried particles into a fibrous morphology that significantly improves dispersibility compared to conventional spray-dried spherical particles, thereby achieving low production cost without sacrificing dispersibility performance.
Solution Approach 2:
The invention makes the dispersibility performance of spray-dried particles equivalent to that of drum-dried particles by controlling the solution viscosity and resulting fibrous morphology. This creates equipotentiality between the two methods, allowing selection of the cheaper spray drying process while achieving the same functional performance.
