Pre-Impactor Ridges for Controlled Tree Nut Shell Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tree nut processing methods cause significant damage to kernels during cracking and shelling due to the lack of controlled outer layer removal.
Innovation Solution
A pre-impaction device with a body and recessed ridges is used to introduce controlled imperfections in the outer layer of nuts, allowing for predictable and minimally invasive shell removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional cracking and shelling procedures are used, then processing speed is maintained, but kernel damage increases significantly
Solution Approach 1:
The pre-impaction device creates controlled imperfections and weaknesses in the shell before the main cracking process. By pre-weakening specific locations on the shell surface, the subsequent cracking force can break the shell along predetermined paths without requiring excessive force that would damage the kernel. This preliminary action allows for gentler cracking conditions while maintaining high processing speed.
2Productivity
If increased force is applied during cracking, then shell removal efficiency improves, but kernel damage increases
Solution Approach 1:
The cracking process is divided into two stages: pre-impaction to create localized weaknesses, and then controlled cracking along those weaknesses. The pre-impaction device segments the shell structure by creating specific imperfections at predetermined locations, allowing the shell to be removed efficiently through controlled cracking rather than requiring high force across the entire shell surface.
3Manufacturing precision
If conventional cracking methods are used, then equipment simplicity is maintained, but kernel damage control is poor
Solution Approach 1:
The pre-impaction device serves as an intermediary between the kernel and the main cracking mechanism. It first creates controlled weaknesses in the shell, which then guide the cracking process. This intermediary step allows for precise control over where cracks initiate and propagate, enabling accurate control of rupture points without requiring complex control systems in the main cracking equipment.
