Curved Roller Poultry Organ Separator Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mechanically processing poultry organs often result in organ loss, damage to organs like the liver and heart, incomplete separation, unintentional retention of organs such as gallbladders, and obstructions in the processing line, with issues like dirt accumulation and inefficient processing times.
Innovation Solution
A processing device with cooperating rollers that have varying cross-sectional diameters and superficial curved contours, allowing for adjustable nips and pockets around the circumference to effectively guide and separate organs, reducing loss and damage by promoting a massaging effect and ensuring consistent passage through the rollers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mechanical processing methods are used to separate organs from poultry, then separation is achieved, but organ loss and damage occur
Solution Approach 1:
The rollers are equipped with curved contours instead of flat surfaces, creating a massaging effect that gently guides organs through the processing line. This curvature allows organs to roll smoothly without sharp impacts, reducing damage and loss while maintaining separation efficiency
Solution Approach 2:
The invention varies the diameter of rollers along their length (different cross-sectional diameters) to create zones of different compression forces. This parameter variation allows gentle handling in some zones and effective separation in others, improving organ integrity while maintaining separation capability
2Manufacturing precision
If conventional processing methods are used, then organs are processed, but incomplete separation and obstructions occur
Solution Approach 1:
Curved roller surfaces prevent organs from getting stuck by providing smooth, continuous contact surfaces. The massaging effect of curved rollers ensures complete separation by gently guiding organs through the nip zone without creating obstructions
Solution Approach 2:
The rollers are designed with varying diameters along their length, creating dynamic compression zones. This dynamic structure adapts to different organ sizes and shapes, ensuring complete separation while preventing obstructions through controlled variability in the processing action
3Productivity
If conventional processing methods are used, then organs are moved through the system, but processing time is inefficient
Solution Approach 1:
The rollers operate continuously with overlapping nip zones, ensuring that organs are processed without interruption. The massaging effect of curved surfaces maintains continuous contact and movement, eliminating idle time and improving processing efficiency
Solution Approach 2:
The varying roller diameters create periodic compression and release cycles as organs move through the processing line. This periodic action maintains steady organ flow and prevents stagnation, improving overall processing efficiency without sacrificing separation quality
4Reliability
If conventional processing methods are used, then organs are separated, but dirt accumulation occurs
Solution Approach 1:
The curved roller surfaces do not create sharp edges or crevices where dirt and organic material can accumulate. The smooth, continuous surfaces are easier to clean and maintain, reducing dirt buildup while preserving separation effectiveness
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces organ loss, minimizes damage, ensures complete separation, and prevents obstructions by maintaining a consistent nip and guiding organs through the rollers, enhancing processing efficiency and reducing dirt accumulation.
Implementation Method 1
two cooperating rollers (1, 2) that define a nip (3) between the rollers for selectively allowing preselected organs from an organ package to pass through the nip. During operation, the rollers rotate in opposite directions in order to convey the organ package and simultaneously promote that preselected organs pass through the nip

AI summary
A method and processing device for processing an organ package taken out from slaughtered poultry is provided. At least two cooperating rollers that define a nip between the rollers selectively allow preselected organs from the organ package to pass through the nip. The rollers during operation rotate in opposite directions in order to convey the organ package and simultaneously promote that the preselected organs pass through the nip, wherein the rollers have a cross-sectional diameter, the value of which varies as seen in the longitudinal direction of the rollers and depends on the location of the cross-section between an entrance portion and an exit portion of the rollers so as to provide each of the rollers with a superficial curved contour.
