Poultry Foot Callus Extraction With Tray-Aligned Rasp Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing foot calluses from poultry feet are inefficient, unsafe, and costly, leading to discarded feet that are unattractive for consumption due to dermatitis lesions.
Innovation Solution
An electromechanical machine with a mechanized rasp system that automatically scrapes off calluses from poultry feet using a toothed shaft and plunger mechanism, ensuring safety and efficiency in operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual removal of calluses is performed, then operation flexibility is maintained, but productivity is low and labor costs are high
Solution Approach 1:
The machine is divided into distinct functional modules: a feeding system with trays and chains, a callus removal system with toothed shafts and plungers, and a discharge system with funnels and conveyor belts. Each module performs a specific function, allowing for efficient callus removal while maintaining manageable structural complexity through modular design.
2Ease of operation
If traditional methods are used, then operational simplicity is maintained, but safety risks increase and economic efficiency decreases
Solution Approach 1:
The machine performs the callus removal operation automatically once the poultry feet are positioned in the trays. The toothed shafts rotate and the plungers press down to scrape off calluses without requiring continuous manual intervention, thereby improving safety while maintaining ease of operation through simple tray feeding.
3Productivity
If feet with dermatitis are discarded, then product quality is maintained, but economic loss increases
Solution Approach 1:
The machine extracts and removes the harmful calluses and dermatitis lesions from the poultry feet through the mechanical action of rotating toothed shafts that scrape the plantar surface. This extraction process restores the feet's appearance and makes them suitable for consumption, thereby improving economic efficiency by preventing discarding of affected feet.
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 machine provides a safe, agile, and economical solution for callus removal, enhancing the attractiveness of poultry feet for consumption by ensuring effective extraction.
Implementation Method 1
causing the rails to be scraped by the friction of that toothed shaft

AI summary
A machine designed to extract calluses from the footpads of poultry—primarily chickens—comprising a cabinet on the inside of which is mounted a pair of chains between which are mounted a plurality of trays having a circular through-opening in the bottom face thereof. Operatively mounted downstream of the chains is a pair of toothed shafts with motorization means and mounted above this region is a smaller chain which is also motorized. Mounted on said chain is a plurality of assemblies comprised of a base (4) and, mounted thereon, a piston (5), the position of which corresponds to the position of the opening (A) in a tray (B) when the latter is below the region of the smaller chain, wherein the piston (5) and the opening (A) are vertically aligned with each other.
