Poultry Carcass Fillet Harvesting with Residual Meat Detaching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for harvesting breast fillets from poultry carcasses often leave residual meat and tissue behind on the breastbone, which are not efficiently removed, leading to suboptimal yield and increased costs for meeting pharmaceutical industry standards for cartilage quality.
Innovation Solution
A system incorporating a detaching device with rollers and/or a scraper is positioned downstream of the fillet harvesting device to automate the removal of residual meat and tissue from the breastbone, utilizing rollers with helical profiles to grip and pull away anchorage tissue and a scraper to adapt to the anatomical shape for efficient tissue removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If breast fillet is harvested by cutting or scraping away from the breastbone, then the breast fillet can be efficiently removed, but residual meat and tissue remain on the breastbone reducing overall yield
Solution Approach 1:
The system divides the harvesting process into two distinct stages: first the breast fillet is harvested by cutting/scraping, then the detaching device with rollers and scrapers removes the residual meat and tissue in a separate step. This segmentation allows each device to be optimized for its specific function, maximizing overall meat recovery while maintaining breast fillet harvesting efficiency.
Solution Approach 2:
The detaching device with rollers and scrapers is positioned to perform preliminary removal of residual tissue before the cartilage is harvested. This preliminary action cleans the breastbone surface, ensuring that when cartilage is subsequently harvested, minimal tissue remains that would contaminate the cartilage product, thereby reducing later processing requirements.
2Reliability
If manual removal of residual tissue and cartilage is performed, then pharmaceutical industry standards for cartilage quality can be met, but labor costs and processing time increase significantly
Solution Approach 1:
The detaching device with rollers and scrapers is designed to automatically remove residual tissue and cartilage from the breastbone without human intervention. The rollers with protrusions grip and pull away tissue, while scrapers mechanically remove cartilage, enabling the system to service itself and maintain pharmaceutical quality standards through automated mechanical action rather than manual labor.
Solution Approach 2:
The system replaces manual mechanical removal with automated mechanical devices. The detaching device uses rollers with protrusions that rotate to grip and pull tissue, combined with scrapers that mechanically remove cartilage, substituting human hands and tools with a controlled mechanical system that maintains consistency and speed.
3Productivity
If automated harvesting of cartilage is implemented, then labor costs decrease and productivity increases, but achieving pharmaceutical industry quality standards becomes difficult
Solution Approach 1:
The detaching device applies different mechanisms to different parts of the breastbone: rollers with protrusions target and remove soft tissue and membrane, while scrapers specifically remove cartilage. This localized approach ensures that each type of tissue is removed by the most effective mechanism, maintaining pharmaceutical quality standards while achieving automated high-speed processing.
Solution Approach 2:
The system controls the rotation speed, pressure, and engagement depth of the rollers and scrapers to optimize tissue removal. By adjusting these parameters, the automated device can gently remove tissue without damaging remaining meat or bone structure, ensuring pharmaceutical quality while maintaining high productivity.
