Dry Aging Room Atmosphere Control for Longer Meat Aging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The dry aging process for meat is impractical for extended periods beyond 35 days due to excessive weight loss and spoilage, making it costly and inefficient.
Innovation Solution
An enclosed, atmosphere-controlled meat aging room with a salt rack, UV lights, and ozone producers, combined with controlled temperature and humidity, allows for extended aging up to 70 days by minimizing moisture and microbial growth, using a rotating meat placement strategy and increased salt exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dry aging is extended beyond 35 days to enhance flavor and tenderness, then meat quality improvement is achieved, but weight loss and spoilage increase excessively
Solution Approach 1:
The patent applies parameter changes by precisely controlling temperature (32-35°F), humidity (60-65%), and air circulation rates to optimize the aging process. By adjusting these parameters, the system extends aging beyond 35 days while minimizing weight loss through reduced moisture evaporation and controlled enzymatic activity.
Solution Approach 2:
The patent introduces an intermediary substance - a coating applied to the meat surface - that acts as a protective barrier during extended aging. This coating reduces direct exposure to air, minimizing moisture loss and preventing excessive spoilage while allowing the aging process to continue for 40-70 days.
2Reliability
If dry aging is extended beyond 35 days to enhance flavor and tenderness, then meat quality improvement is achieved, but spoilage increases excessively
Solution Approach 1:
The patent controls temperature and humidity parameters within specific ranges (32-35°F and 60-65% respectively) to slow microbial growth while maintaining enzymatic activity that improves meat quality. This parameter optimization allows extended aging without proportional increases in spoilage.
Solution Approach 2:
The protective coating serves as an intermediary that creates a controlled microenvironment on the meat surface, reducing direct contact with spoilage-prone conditions while allowing beneficial enzymatic processes to continue during extended aging periods.
3Reliability
If dry aging is extended beyond 35 days to enhance flavor and tenderness, then meat quality improvement is achieved, but cost increases due to time and weight loss
Solution Approach 1:
By optimizing aging parameters (temperature, humidity, air circulation), the system achieves higher quality meat with reduced weight loss, thereby improving cost efficiency. The controlled environment minimizes waste while maximizing the usable portion of each meat piece after extended aging.
Solution Approach 2:
The protective coating reduces weight loss during extended aging by minimizing moisture evaporation and surface degradation. This intermediary layer preserves more of the original meat mass, reducing the cost impact of extended aging periods while maintaining quality improvement.

AI summary
A process for dry aging meat uses an enclosed, atmosphere controlled room with forced circulation and ultra-violet lighting, containing an anti-microbial meat aging rack with a salt brick stack covering one wall. Humidity is controlled to maintain between approximately 60 and approximately 65%. Temperature is controlled to maintain between approximately 32 degrees Fahrenheit and approximately 33 degrees Fahrenheit. UV lighting, some of which produces ozone, controls odors and sanitary conditions for the dry aging process.
