Solution Overview

Problem

Existing methods for harvesting backmeat from poultry carcasses require cumbersome incisions before filleting, leading to increased processing costs and inconsistent quality due to variations in carcass dimensions, which can result in bone splinters and reduced meat quality.

Innovation Solution

Fixing the neck portion of the backbone in position and scraping the backmeat loose along the scapula, avoiding preparatory incisions, using fixing and scraping means that operate in tandem to ensure reliable separation while maintaining connection with fillet meat, allowing for complete harvesting without damaging the scapula.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If rotating blades are used to make incisions in the backmeat, then the backmeat can be separated from the carcass, but bone splinters may be produced and meat quality deteriorates

Engineering Contradiction:
Improveseparation reliabilityVSAvoidbone splinters
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical cutting action of rotating blades with a chemical/enzymatic process. The backmeat is treated with an enzyme solution (such as proteases) that breaks down the connective tissue and muscle fibers, allowing the backmeat to be separated from the carcass without mechanical contact that would produce bone splinters. This substitution of mechanical cutting with biochemical degradation eliminates the harmful effect while achieving the separation function.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If preparatory incisions are made before filleting, then the backmeat can be harvested, but the processing time increases and costs increase

Engineering Contradiction:
Improvebackmeat harvestingVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by treating the backmeat with enzyme solution before the filleting process begins. This pre-treatment softens and loosens the backmeat from the carcass, so that during the subsequent filleting operation, the backmeat can be easily harvested along with the fillets without requiring separate incision steps. The preliminary enzymatic treatment integrates the backmeat separation function into the existing filleting workflow, eliminating additional time-consuming operations.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If rotating blades are used for backmeat separation, then the backmeat can be harvested, but the precision is insufficient due to carcass dimension variations

Engineering Contradiction:
Improvebackmeat harvesting efficiencyVSAvoidincision precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent changes the fundamental parameter of the separation process from mechanical cutting (with fixed blade geometry) to enzymatic degradation (with adjustable solution concentration and contact time). By controlling parameters such as enzyme concentration, temperature, and treatment duration, the process can adapt to varying carcass dimensions without requiring precise mechanical positioning. The enzymatic solution penetrates and acts on the backmeat tissue regardless of slight variations in carcass size, ensuring consistent separation results across different poultry varieties.

Inventive Principle:
Principle #35Parameter changes

AI summary

A method and apparatus for harvesting of backmeat of a carcass or carcass part of slaughtered poultry in connection with a process of filleting of the carcass or carcass part is provided. The method can include scraping the backmeat loose from the carcass or carcass part whereby a connection is maintained with fillets of the carcass or carcass part. Prior to the filleting of the carcass or carcass part a neck portion of a backbone of the carcass or carcass parts is fixed in position, whereby thereafter the backmeat is scraped loose from the carcass or carcass part.
