Curved Roller Nip for Poultry Organ Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mechanically processing poultry organs often result in organ loss, damage, incomplete separation, and obstructions in the processing line, with issues like dirt accumulation and inefficient organ positioning.
Innovation Solution
A processing device with cooperating rollers of varying cross-sectional diameters and adjustable nips, featuring superficial curved contours and pockets, to effectively guide and separate organs, reducing loss and damage by controlling the conveying speed and positioning of organs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional rolling methods are used to separate organs, then separation speed is maintained, but organ loss and damage increase due to inefficient positioning and handling
Solution Approach 1:
The rollers are equipped with curved contours instead of flat surfaces, creating zones with varying diameters along their length. This curvature enables better adaptation to organ shapes and improves positioning accuracy during separation, reducing organ damage while maintaining separation speed.
Solution Approach 2:
Different sections of the rollers have different diameters (varying cross-sectional diameters) to create localized zones with specific functions. These zones provide differentiated handling characteristics for different parts of the organ package, improving overall separation efficiency and organ integrity.
2Device complexity
If rollers with constant diameter are used, then device simplicity is maintained, but separation efficiency decreases due to inability to adapt to varying organ positions
Solution Approach 1:
The rollers feature curved contours with varying diameters along their length, allowing them to adapt to different organ positions and shapes. This design maintains a relatively simple roller structure while significantly improving separation efficiency through the created zones with differentiated characteristics.
3Productivity
If high conveying speed is used to increase productivity, then processing throughput is improved, but organ positioning accuracy deteriorates leading to loss and damage
Solution Approach 1:
The curved contours of the rollers create zones that can gently guide and position organs even at higher conveying speeds. The varying diameters provide natural guiding surfaces that maintain positioning accuracy without requiring reduction of conveying speed, thus preserving both throughput and precision.
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 enhances the separation efficiency of organs, reduces loss and damage, and prevents obstructions by ensuring effective positioning and processing of organs, while maintaining a constant nip width for improved handling of small or weak organs.
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.
