Angled Skinning Roller for Poultry Leg Skin Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deskinning devices for poultry leg products often result in incomplete skin removal, skin tearing at undesired locations, and a visually unpleasing meat product.
Innovation Solution
A deskinning device with a skin removal assembly that includes a first rotatable skinning roller with a higher first roller end and a lower second roller end, a counter skinning member, and a gap between them, allowing the skin to be pulled upwards and into the gap for efficient removal without preparatory cuts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional skin removal assemblies with horizontally oriented rollers are used, then the skin can be pulled from the poultry leg, but the skin may break or tear at undesired locations and the removal is not complete
Solution Approach 1:
The skinning rollers are inverted from horizontal orientation to upward倾斜 orientation, with the upper roller end positioned higher than the lower roller end. This inversion changes the direction of skin pull from horizontal to upward, allowing the skin to be pulled off in a single piece without tearing or breaking at undesired locations.
Solution Approach 2:
The orientation parameter of the skinning rollers is changed from horizontal to upward倾斜. Specifically, the roller axis is arranged at an angle between 10-45 degrees relative to the horizontal plane, which fundamentally changes the mechanics of skin removal and prevents tearing while ensuring complete removal.
2Ease of operation
If preparatory cuts are made in the poultry leg before skin removal, then the skin can be more easily removed, but the meat product becomes visually unpleasing
Solution Approach 1:
The skinning rollers are designed with upward倾斜 orientation and specific surface characteristics that enable them to grip and pull the skin off in a single continuous motion without requiring any preliminary cutting actions. This preliminary action capability is built into the roller design itself, eliminating the need for separate cutting steps that would damage appearance.
Solution Approach 2:
The skin removal process extracts only the skin from the poultry leg without requiring any extraction or removal of meat tissue. The upward-pulling mechanism cleanly separates skin from meat, leaving the meat product intact and visually appealing without any cut marks or damage.
3Device complexity
If horizontally oriented skinning rollers are used, then the device structure is simple, but the skin removal is not complete and may tear
Solution Approach 1:
The roller orientation is inverted from horizontal to upward倾斜, which only requires changing the mounting angle of the rollers rather than redesigning the entire mechanism. This simple geometric inversion achieves complete skin removal without tearing while maintaining relatively simple device structure.
Solution Approach 2:
The key parameter change is the roller axis orientation angle, set between 10-45 degrees from horizontal. This single parameter modification transforms the skin removal outcome from incomplete and tearing-prone to complete and clean, without significantly increasing device complexity.

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 device achieves better skin removal with reduced risk of tearing, allows for more predictable skin removal, and omits the need for preparatory cuts, resulting in a cleaner and more visually appealing meat product.
Implementation Method 1
a first skinning roller (110) which is rotatable about an axis of rotation (111) which extends in a longitudinal direction of the first skinning roller (110)
