Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing cereal-based food products and adhesives are costly and require excessive food additives, while existing milling devices cannot efficiently impart viscosity to cereal grains, leading to prolonged production times and increased costs.
Innovation Solution
A milling device with a rotatable screw and barrel featuring spiral grooves of varying pitches and angles, capable of grinding and blasting cereal grains efficiently, producing cereal flour that can be used to prepare dough or adhesives without additional thickeners, thereby reducing production time and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If gluten or thickeners are added to rice flour to impart viscosity, then the desired dough consistency is achieved, but production cost increases and food additives are used
Solution Approach 1:
The patent changes the physical parameters of rice grains through controlled grinding and blasting processes, transforming them into angular particles with specific size distributions that naturally impart viscosity when mixed with water, eliminating the need for gluten or thickener additives
Solution Approach 2:
The patent replaces the chemical system (gluten/thickeners) with a mechanical system (controlled grinding and blasting) to achieve the desired viscosity, substituting chemical additives with physically modified cereal particles
2Reliability
If traditional adhesive production methods are used with multiple steps, then adhesive properties are achieved, but production time is prolonged and costs increase
Solution Approach 1:
The patent combines multiple traditional processing steps (grinding, drying, sizing) into a single integrated blasting operation that achieves all necessary particle modifications simultaneously, dramatically reducing production time while maintaining adhesive quality
Solution Approach 2:
The blasting process performs preliminary particle shape modification and size classification in one operation, preparing the cereal particles for direct adhesive application without requiring subsequent processing steps
3Strength
If cereal grains are not properly ground and blasted, then production process is simple, but viscosity cannot be imparted to prepare dough
Solution Approach 1:
The patent segments the grinding process into distinct functional zones within the mill, with each zone performing a specific particle size reduction or shape modification function, allowing complex particle engineering through a systematically divided mechanical process
Solution Approach 2:
The patent introduces a blasting dimension to traditional grinding, adding a high-velocity impact phase that fundamentally changes particle morphology from rounded to angular, creating a new processing dimension that enhances viscosity without proportionally increasing device complexity
