Angled Guide Member for Poultry Viscera Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern poultry slaughtering systems face challenges in precisely separating intestines and gallbladders from the remaining viscera set at high processing speeds, often resulting in liver tissue being discarded or contaminated due to improper separation techniques.
Innovation Solution
A method and system involving a guide member with an angled separation support surface, where the viscera set is arranged such that the intestines and gallbladder are suspended below and the liver above, allowing for precise separation by moving the guide member to align the gallbladder with the opening, reducing contamination and discarding of liver tissue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the processing speed is increased to improve productivity, then the separation precision deteriorates due to the high speed causing improper separation and contamination
Solution Approach 1:
The guide member is made movable rather than stationary, allowing it to dynamically adjust its position to accommodate natural variations in viscera sets while maintaining high processing speeds. The guide member can move to follow the contours of different viscera configurations, ensuring precise separation without sacrificing speed.
Solution Approach 2:
The separation support surface is arranged at an angled orientation rather than horizontally, changing the geometric parameter to facilitate proper positioning of the liver and gizzard above the guide plates. This angular configuration optimizes the separation process by allowing gravity to assist in positioning while maintaining high-speed operation.
2Device complexity
If a stationary guide member is used to maintain simplicity, then the adaptability to natural variations in viscera sets deteriorates
Solution Approach 1:
The guide member transitions from a stationary to a movable component, enabling it to adapt to natural variations in viscera set configuration. This dynamic capability allows the guide member to follow the contours of different viscera arrangements while maintaining separation precision.
Solution Approach 2:
The movable guide member automatically adjusts its position in response to the natural variations in viscera sets without requiring complex control systems or external intervention. The movement is driven by the interaction between the guide member and the viscera sets themselves, providing self-adaptation.

Function Achieved in This Case
This approach enables precise separation of intestines and gallbladders from the remaining viscera set at high processing speeds, minimizing liver tissue discard and contamination risks, while maintaining efficient processing.
Implementation Method 1
The angling of the separation support surface allows the liver and gizzard to slide towards the lower end of the elongate opening

AI summary
Disclosed is a method and a system for separating a viscera set (1) eviscerated from slaughtered poultry and held by a viscera holder (2) of a viscera conveyer in manner whereby at least the liver (16), the intestines (15) and the gallbladder (18) are suspended below said viscera holder (2). The method comprises the steps of: arranging said viscera set in an elongate opening (43) of a guide member (4) and separating the intestines (15) and the gallbladder (18) from the remaining viscera set. The intestines (15) and the gallbladder (18) are separated from the remaining viscera set while at least said liver (16) rests on a separation support surface (44) of the guide member (2), arranged with an angle relative to the horizontal plane. A guide assembly having two movable parts for use in such method / system is further disclosed.
