Gizzard Processing Device Helical Roller Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for processing poultry organs in processing lines face issues such as organ loss, damage, incomplete separation, and inefficiencies due to complex and costly equipment, high water and energy usage, and poor handling of organ packages, particularly with the gizzard and pre-stomach.
Innovation Solution
A gizzard processing device with cooperating rollers having helically shaped grooves positions and transports the gizzard-package upright, featuring a slope portion with a centrally positioned knife and angled sides to open the gizzard into a butterfly shape, releasing contents, and a cutting device to separate the gizzard from the pre-stomach, accompanied by a washing beam for cleaning and a gizzard peeler for further peeling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional processing lines use multiple complex processing devices for sequential organ harvesting, then organ separation capability is improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent combines multiple processing functions (positioning, cutting, separating, and cleaning of gizzard and pre-stomach) into a single integrated processing device. The device features a V-shaped groove that simultaneously positions and orients the organ package, while a centrally positioned knife performs cutting operations, and a washing beam provides cleaning functionality, eliminating the need for separate processing devices for each operation.
Solution Approach 2:
The processing device is designed with multi-functional capabilities to handle various organ processing tasks within a single unit. The V-shaped groove structure serves multiple purposes: positioning the organ package, orienting the gizzard and pre-stomach, and guiding the cutting operation. The centrally positioned knife can process different organ configurations, and the washing beam provides universal cleaning functionality, making the device adaptable to different processing requirements without requiring multiple specialized devices.
2Productivity
If traditional processing lines use multiple processing devices with sequential operations, then organ harvesting completeness is improved, but processing time and energy consumption increase
Solution Approach 1:
The patent implements continuous processing within a single device, where the organ package moves through positioning, cutting, and cleaning operations in one continuous flow. The V-shaped groove maintains continuous contact and orientation of the organ package, the centrally positioned knife performs cutting in a single pass, and the washing beam provides continuous cleaning, eliminating the start-stop operations and energy consumption associated with multiple sequential devices.
Solution Approach 2:
The device segments the processing operations into distinct functional zones within a single integrated structure. The V-shaped groove creates a positioning zone, the centrally positioned knife creates a cutting zone, and the washing beam creates a cleaning zone. This segmentation allows each function to be performed efficiently in sequence within one device, reducing the energy consumption that would result from multiple separate devices requiring individual power cycles and transitions.
3Manufacturing precision
If traditional processing lines handle organ packages with multiple devices, then organ separation precision is improved, but organ damage risk increases
Solution Approach 1:
The V-shaped groove acts as an intermediary structure that gently positions and orients the organ package without requiring harsh mechanical manipulation. The groove guides the gizzard and pre-stomach into the correct position for cutting, and the washing beam provides a gentle cleaning action. This intermediary positioning mechanism eliminates the need for rough handling and complex mechanical manipulations that could damage delicate organs, while still achieving precise separation.
4Manufacturing precision
If traditional processing lines use extensive water supply for washing, then cleaning effectiveness is improved, but water consumption increases
Solution Approach 1:
The patent extracts the essential cleaning function from complex multi-device washing systems and implements it through a single washing beam integrated into the processing device. The washing beam targets only the specific areas requiring cleaning (the gizzard and pre-stomach) rather than applying water throughout the entire processing line. This focused approach maintains cleaning effectiveness while significantly reducing overall water consumption by eliminating redundant washing operations in separate devices.
