Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for wetting grains with a liquid to produce flour require long standing times, leading to space constraints, increased germ and mold formation, and limited water addition capacity, resulting in lower flour yields.
Innovation Solution
A vibrating device with a tube non-positively connected to a motor base plate, allowing for efficient transfer of vibration energy to grains, enabling higher water addition and reduced standing times, while maintaining hygiene and improving flour yield.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If grains are mixed with water in a screw conveyor and left for 12-72 hours, then the shells soften and can be peeled off, but a large amount of space is required for storage during the standing period
Solution Approach 1:
The patent applies mechanical vibration through a vibrating device with an oscillating tube to accelerate water penetration into grain shells. The vibration energy enhances the softening process, reducing the required standing time from 12-72 hours to just 2-4 hours, thereby significantly reducing storage space requirements while maintaining effective shell softening for peeling.
2Manufacturing precision
If grains are stored for long periods to soften shells, then peeling can be performed, but increased total germ counts as well as yeast and mold formation occur
Solution Approach 1:
The vibrating device accelerates the water penetration and shell softening process, reducing standing time from 12-72 hours to 2-4 hours. This time reduction prevents the development of harmful germs, yeast, and mold that typically occur during prolonged storage, while still achieving adequate shell softening for effective peeling.
3Ease of manufacture
If vibration energy is transferred through a long tube to grains, then the tube can be connected to the motor, but the vibration energy is not completely transferred to the grain
Solution Approach 1:
The patent optimizes the tube length parameter to a maximum of twice the motor base plate length and positions the tube non-positively (at an angle or offset) relative to the motor base plate. This parameter optimization ensures complete vibration energy transfer from the motor to the grains while maintaining easy motor connection, eliminating energy loss to tube vibrations.
4Productivity
If more liquid is added to grains in one pass, then water addition efficiency increases, but the device complexity increases
Solution Approach 1:
The vibrating device with oscillating tube enables high-velocity liquid-grain contact through vibration-induced mixing, allowing 12% water addition in a single pass. This vibration-based mixing mechanism achieves high productivity without requiring complex multi-stage mixing systems, maintaining relatively simple device structure.
