Poultry Breast Fillet Separation Using Pivotable Guiding Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for separating breast fillets from poultry carcasses often result in cutting errors due to the breast fillets folding together, leading to yield losses and inadequate quality of separated meat.
Innovation Solution
The apparatus features pivotable guiding elements that increase the distance between the breast bone and separating means, and a spreading element to keep the breast fillets apart, preventing folding and ensuring a clean separation by moving the guiding elements apart after the breast bone is threaded between the separating means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the breast fillets are guided between fixed guiding elements during separation, then the guiding structure is simple and stable, but the breast fillets fold together and clamp, causing cutting errors and yield loss
Solution Approach 1:
The guiding elements are made movable rather than fixed, allowing them to dynamically adjust their position. The guiding elements can move apart in the transport direction to accommodate the breast fillets during separation, preventing folding and clamping while maintaining guiding function. This dynamic adjustment eliminates the contradiction between stable guiding and preventing meat folding.
2Device complexity
If the guiding elements are positioned close to the separating means, then the guiding structure is compact, but the breast fillets cannot be kept apart during separation
Solution Approach 1:
The guiding elements are designed to be movable in the transport direction, allowing them to dynamically increase the distance from the separating means when needed. This enables the structure to remain compact in normal operation while providing sufficient space during separation to keep breast fillets apart, achieving both compactness and separation precision.
Solution Approach 2:
The position of the guiding elements is made variable rather than fixed. By changing the position parameter of the guiding elements dynamically during the separation process, the system can optimize the distance between guiding elements and separating means, achieving both compact structure and precise separation.
3Ease of operation
If the breast fillets are allowed to hang down naturally during transport, then the transport process is simple, but the breast fillets fold together at the breast bone area
Solution Approach 1:
The guiding elements dynamically adjust their position to actively manage the configuration of breast fillets during transport and separation. Rather than allowing natural hanging, the movable guiding elements maintain the fillets in an optimal configuration, preventing folding while adding minimal complexity to the transport process.

AI summary
The invention relates to an apparatus for completely separating from the carcass of a gutted poultry body breast fillets that have already been partially detached from the carcass, comprising a pair of separating means for separating the breast fillets hanging down on both sides of the breast bone of the carcass from the breast bone as well as guiding means for guiding the carcass in the direction of the two separating means arranged at a distance from one another, wherein the guiding means comprises two guiding elements lying next to one another and at a distance from one another, which between them form a gap which is directed in the transport direction T of the poultry bodies for receiving and guiding the breast bone of the carcass, and wherein the separating means enter this gap from below in such a way that the separating means for separating the breast fillets from the breast bone protrude upwards beyond the guiding means in the direction of the carcass, which is distinguished by the fact that the guiding elements are pivotable out of a guiding position forming the gap into a waiting position increasing the distance A to the separating means and vice versa and in that a spreading element for spreading the breast fillets away from the breast bone during the separating operation is provided. Furthermore, the invention relates to a corresponding method.
