Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for eggshell membrane separation are inefficient in distinguishing and separating the brittle outer portion from the elastic membrane, often resulting in damage to the membrane during processing.
Innovation Solution
An eggshell membrane separation system utilizing a venturi to process unprocessed eggshells, where the interaction of eggshells with shock waves and pressure changes pulverizes the brittle outer portion while preserving the elastic membrane, using airflow velocity and geometry to control the separation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current separation methods are used, then eggshell membranes can be separated, but the membranes are damaged during processing
Solution Approach 1:
The patent replaces traditional mechanical separation methods (which physically contact and damage membranes) with a pneumatic system using a venturi generator. The venturi creates controlled airflow and pressure differentials that separate membranes through aerodynamic forces rather than mechanical contact, thereby maintaining membrane integrity while achieving efficient separation.
Solution Approach 2:
The invention employs pneumatic principles by using a venturi generator to create controlled airflow patterns. The venturi effect generates regions of high and low pressure that manipulate eggshell-membrane assemblies in flight, enabling separation based on aerodynamic properties without mechanical contact, thus solving the contradiction between gentle handling and efficient separation.
2Reliability
If gentle handling is used to preserve membranes, then membrane integrity is maintained, but separation efficiency decreases
Solution Approach 1:
The venturi generator allows precise control of airflow parameters (velocity, pressure, turbulence) to optimize separation. By adjusting these pneumatic parameters, the system achieves high separation quality that distinguishes intact membranes from debris without requiring harsh mechanical handling, thus maintaining both membrane integrity and separation precision.
3Productivity
If traditional processing methods are used, then processing speed is maintained, but membrane damage increases
Solution Approach 1:
The system replaces mechanical processing (contact-based) with pneumatic processing (contactless). The venturi-generated airflow rapidly accelerates eggshell-membrane assemblies through controlled turbulence and pressure changes, achieving fast processing speeds while eliminating mechanical contact that causes membrane damage.
Solution Approach 2:
The venturi generator creates periodic turbulence and pressure fluctuations in the airflow. This periodic action continuously reorients and accelerates eggshell-membrane assemblies, enhancing separation efficiency and processing speed while the contactless nature of the pneumatic forces prevents membrane damage throughout the cyclic process.

AI summary
A system and process for separating eggshell membranes from eggshells. The system and process may utilize airflow through a venturi to pulverize the eggshell and thereby separate the eggshell from the membrane. Furthermore, in some embodiments, the process may also extract moisture from the membrane and eggshell. The system may further be configured to collect the pulverized eggshell particles separately from the membrane material.
