Abstract

A comminution apparatus is disclosed with at least three sequential feature sets which when configured for relative rotation a sequential pair of feature sets is capable of comminution where relative rotation of at least two feature sets is configured to occur about a single axis, and at least one drive system configured to facilitate said rotation for the at least two feature sets, and wherein the rotation of at least one feature set is configured to occur in a distinct manner to that of the rotation of at least one other feature set.

Abstract

The present invention relates to a rotational fluidic device and method for efficiently dissolving or emulsifying compounds from granular materials, such as coffee or tea, in both hot and cold brew coffee extraction processes, as well as for infusing beverages like cocktails or other drinks. The inventive method employs a holder for the granular material, a vessel with a specific geometry, and a mechanism for providing rotational motion to the holder, creating a fluidic rotation within the vessel. The fluid rotation enhances the extraction and emulsification process, resulting in improved extraction efficiency, reduced brewing time, and enhanced flavour profiles. The invention is versatile, capable of brewing both hot and cold coffee and infusing a variety of beverages, overcoming limitations and drawbacks of traditional brewing and infusion methods.
