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 flash brewed coffee concentrates. However, the original method was limited to general applications and did not address the unique challenges and requirements of specific, niche environments and applications. This invention solves the problem of adapting the flash brewed coffee concentrate production process to these specialized contexts.

Novelty and Inventive Step

The novelty of this invention lies in the adaptation of the flash brewed coffee concentrate production process to specific, niche environments and applications. The inventive step is the recognition of the need for specialized systems and methods to address the unique challenges and requirements of these contexts, and the development of novel solutions to meet those needs.

Alternative Embodiments and Variations

Alternative embodiments of the invention could include the use of modular brewing units, adjustable brewing parameters, and integrated quality control systems. Variations of the invention could include the use of different coffee bean varieties, brewing temperatures, and coffee-to-water ratios to optimize the flavor profile of the flash brewed coffee concentrate.

Potential Commercial Applications and Market

The invention has significant commercial potential in the coffee industry, particularly in the areas of disaster relief, high-altitude environments, extreme weather conditions, high-security facilities, and remote areas. The invention could be marketed as a specialized solution for these niche applications, offering a unique value proposition to customers operating in these contexts.
