Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for separating egg shells and egg shell membranes require large-scale and complex equipment, making them inefficient and costly for small-scale operations.
Innovation Solution
Adding an egg shell with an attached membrane to a swirling alkaline solution allows for the detachment and separation of the membrane from the shell, utilizing the difference in specific gravity and the alkaline solution's properties to efficiently recover both components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional separation methods using jet mills or hydraulic cyclones are employed, then separation efficiency is improved, but device complexity and scale increase
Solution Approach 1:
The invention changes the chemical parameter of the separation medium by using alkaline solution instead of water or air. The alkaline solution chemically dissolves the eggshell membrane while leaving the eggshell intact, achieving separation through chemical parameter change rather than mechanical force or density difference. This simplifies the equipment to essentially a container for the chemical reaction.
Solution Approach 2:
The invention replaces mechanical separation systems (jet mills, hydraulic cyclones, vibrating sifters) with a chemical separation system. Instead of using mechanical energy to crush and separate components, the alkaline solution chemically removes the membrane, substituting a chemical process for complex mechanical systems.
2Manufacturing precision
If conventional separation methods are used, then separation efficiency is improved, but energy consumption increases
Solution Approach 1:
The invention replaces energy-intensive mechanical separation processes with a low-energy chemical process. The alkaline solution separates the membrane from the shell through chemical dissolution rather than mechanical force, dramatically reducing energy consumption while maintaining separation efficiency.
Solution Approach 2:
The invention changes from physical separation parameters (velocity, pressure, density) to chemical separation parameters (pH, chemical reactivity). This parameter change enables separation at ambient temperature and pressure, eliminating the need for high-energy mechanical systems.
3Device complexity
If simple separation methods are used, then device complexity is reduced, but separation efficiency decreases
Solution Approach 1:
The invention uses chemical parameter change (alkaline dissolution) to achieve complete separation in a simple container. The chemical reaction selectively removes the membrane while preserving the shell, achieving high separation efficiency without complex mechanical systems or multiple processing stages.
Solution Approach 2:
The invention extracts the membrane from the eggshell through chemical dissolution in alkaline solution. The membrane is selectively removed while the shell remains intact, achieving separation by taking out the unwanted component through chemical means rather than mechanical separation.
4Manufacturing precision
If mechanical crushing methods are used, then separation is achieved, but the eggshell membrane degrades
Solution Approach 1:
The invention replaces mechanical crushing with chemical dissolution to separate the membrane. The alkaline solution chemically removes the membrane without mechanical force, preventing degradation and maintaining the membrane's structural integrity for potential further use.
Solution Approach 2:
The invention changes from mechanical separation parameters to chemical separation parameters. The alkaline solution selectively dissolves the membrane through chemical reaction rather than mechanical force, avoiding the harmful mechanical stress that causes degradation while achieving complete separation.
