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. 11,856,964.

Background and Problem Solved

The original patent disclosed a method for producing a flash brewed coffee concentrate, but it had limitations in terms of production speed, flavor profile customization, and shelf life. The new invention addresses these limitations by introducing a system that can produce coffee concentrates at least 10 times faster than traditional cold brew methods, with customized flavor profiles and concentrations, and a shelf life of at least 6 months.

Novelty and Inventive Step

The new claims introduce a paradigm shift in coffee concentrate production by leveraging advanced technologies to achieve unprecedented speed, quality, and customization. The invention's novelty lies in the integration of flash brewing, rapid chilling, and concentration adjustment modules, as well as the ability to create bespoke coffee concentrates with customized flavor profiles and concentrations.

Alternative Embodiments and Variations

Alternative embodiments of the invention could include the use of different brewing technologies, such as pressure brewing or vacuum brewing, to achieve the desired flavor profile and concentration. Additionally, the system could be adapted for use with different types of coffee beans, roast levels, and brewing times to create a wide range of customized coffee concentrates.

Potential Commercial Applications and Market

The next-generation flash brewed coffee concentrate production system has significant commercial potential in the coffee industry, particularly in the cold brew and specialty coffee segments. The system's ability to produce high-quality, customized coffee concentrates with unprecedented speed and shelf life makes it an attractive solution for coffee manufacturers, cafes, and restaurants seeking to differentiate themselves in a competitive market.
