Intact Animal Carcass Processing via Segmented Charring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for processing intact animal carcasses for preservation often result in burnt outer skin, which poses challenges for immigrants seeking to maintain cultural practices while adhering to sanitary and regulatory standards in North America.
Innovation Solution
A method involving submersion in scalding water, de-hairing, charring the epidermal layer, pressure washing, evisceration, internal washing, and chilling of the carcass to produce a sanitized and culturally consistent processing method for intact animal carcasses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an animal carcass is roasted immediately after killing, then the outer skin becomes burnt, but the cultural tradition is preserved
Solution Approach 1:
The process segments the charring action from the cooking action. The epidermal layer is charred separately in step (e) before the meat is roasted in steps (f) and (g). This allows the cultural tradition of charring to be preserved while preventing the harmful effect of burnt skin by isolating the charring to only the outer layer.
Solution Approach 2:
The epidermal layer is removed and charred before the actual roasting process begins. This preliminary charring action allows the cultural tradition to be maintained while the subsequent roasting of the exposed meat produces the desired cooked product without burnt skin.
2Adaptability or versatility
If traditional charring methods are used on intact carcasses, then cultural practices are maintained, but sanitary standards are compromised
Solution Approach 1:
The process segments the carcass processing into distinct sanitary steps: scalding to remove hair, selective charring of only the epidermal layer, thorough pressure washing, and evisceration. This segmentation allows cultural charring tradition to be maintained while each step contributes to sanitary compliance.
Solution Approach 2:
The epidermal layer acts as an intermediary that is removed and charred separately. This allows the charring tradition to be satisfied while the underlying meat remains protected and can be properly sanitized through pressure washing and other sanitary measures.
3Object-affected harmful factors
If the epidermal layer is completely removed, then hair and char can be easily eliminated, but the cultural appearance of charred skin is lost
Solution Approach 1:
The process applies different treatments to different parts of the carcass. The epidermal layer containing hair is removed and charred separately, while the underlying meat is pressure washed and sanitized. This local differentiation allows hair removal while preserving the ability to create a charred appearance on the meat surface through controlled charring of the epidermal layer.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method ensures sanitary processing of intact animal carcasses, allowing for cultural preservation while meeting regulatory requirements by effectively removing hair and char, ensuring food safety and compliance with health standards.
Implementation Method 1
submerging a bled animal carcass in scalding water for at least 20 seconds
Implementation Method 2
burning an epidermal layer of the de-haired animal carcass while suspended so that a majority of the epidermal layer is charred
Implementation Method 3
pressure washing the externally charred animal carcass to produce a pressure-washed animal carcass
Implementation Method 4
chilling the internally washed animal carcass to a temperature of between 0 degrees Celsius and about 4 degrees Celsius

AI summary
A method for processing an intact animal carcass comprises submerging a bled animal carcass in scalding water for at least 20 seconds to produce a scalded animal carcass, de-hairing the scalded animal carcass to produce a de-haired animal carcass, suspending the de-haired animal carcass, burning an epidermal layer of the de-haired animal carcass while suspended so that a majority of the epidermal layer is charred so as to produce a burnt animal carcass, pressure washing the burnt animal carcass to produce a pressure-washed animal carcass, eviscerating the pressure-washed animal carcass to produce an eviscerated animal carcass, internally washing the eviscerated animal carcass to produce an internally washed animal carcass, and chilling the internally washed animal carcass to a temperature of between 0 degrees Celsius and about 4 degrees Celsius to produce a chilled animal carcass.
