This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,856,960.

Background and Problem Solved

The original patent 'Separation method of fat and lean using acidic fluid with nanobubbles' has limitations in terms of temperature control, mechanical separation, and sanitization. The present invention addresses these limitations by introducing a cryogenic freezing tunnel, mechanical separator, and sanitized system to improve the overall efficiency and safety of the separation process.

Novelty and Inventive Step

The new claims introduce the use of a cryogenic freezing tunnel, mechanical separator, and sanitized system, which are not present in the original patent. The combination of these components with the cryogenic fluid and nanobubbles provides a novel and non-obvious solution to the limitations of the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the invention could include using different types of cryogenic fluids, varying the temperature range, or incorporating additional sensors to monitor the separation process. Variations could also include using the system for separating other types of materials or implementing the system in different industries.

Potential Commercial Applications and Market

The enhanced fat and lean meat separation system has significant commercial potential in the meat processing industry, providing improved efficiency, safety, and quality of the separation process. The system could be marketed to meat processing companies, slaughterhouses, and other industries that require efficient and safe separation of fat and lean meat.
