Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems and processes are unable to effectively separate organic matter from inorganic matter in egg by-products, particularly in unhatched egg by-products, which contain a mix of membranes, embryos, and shells.
Innovation Solution
A method involving a drying step, a milling step, and a separating step to process egg by-products. The method includes drying the egg by-products, milling them to reduce particle size, and then separating the organic and inorganic matter based on density, with optional sieving for further separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If current separation systems are used on unhatched egg by-products, then the process is simple, but the separation of organic matter from inorganic matter is ineffective
Solution Approach 1:
The separation process is divided into distinct stages: drying step to remove moisture, milling step to reduce particle size and create size differentiation, and separation step to divide organic and inorganic matter. This segmentation allows each stage to optimize for its specific function, achieving effective separation that simple systems cannot accomplish.
Solution Approach 2:
The drying and milling steps are performed as preliminary actions before the actual separation. Drying removes moisture that would interfere with separation, and milling reduces particle size to create density and size differences that enable effective separation. These preliminary actions prepare the material in a state conducive to successful separation.
2Manufacturing precision
If unhatched egg by-products are processed without drying and milling, then the process is faster, but the separation purity is low
Solution Approach 1:
The drying step changes the moisture content parameter of the egg by-products, removing water that would otherwise prevent effective separation. The milling step changes the particle size parameter, creating size and density differences between organic and inorganic components. These parameter changes are essential for achieving high separation purity.
Solution Approach 2:
The process continues through multiple sequential steps (drying → milling → separation) without interruption, with each step building on the previous one. The continuous application of these useful actions ensures that the material is progressively prepared and separated to the required purity level.
3Manufacturing precision
If density-based separation is used, then organic and inorganic matter are effectively separated, but additional equipment is required
Solution Approach 1:
The milled egg by-products material serves as an intermediary state between the original mixed material and the final separated components. The milling process creates a material with specific physical properties (particle size, density distribution) that act as an intermediate form, enabling the density-based separator to effectively distinguish and separate organic from inorganic matter.

AI summary
A method of separating organic matter and inorganic matter from egg by-products material includes a drying step, a milling step, and a separating step. In the drying step, an amount of egg by-products material is dried to create a dried egg by-products material. During the milling step, the dried egg by-products material is milled to create a milled egg by-products material. The milled egg by-products material is then separated into an amount of organic matter and an amount of inorganic matter in the separating step. The egg-by products material includes at least unhatched egg by-products.
