Method for preparing a beverage or liquid food and system using brewing centrifugal force

摘要

A method for preparing a beverage or liquid from a food substance contained in a filtering receptacle by passing water through the substance using brewing centrifugal forces. The method includes feeding water into the receptacle, and driving the receptacle in centrifugal rotation to force water to flow through the substance in a centrifugal flow path to the outlet of the receptacle. The receptacle is a sealed capsule which is opened for water to be introduced into the capsule, contains a predetermined dose of food substance and is discarded after use.

1. A method for preparing a beverage in a beverage preparation device from a predetermined does of a beverage substance contained in a filtering capsule, which method comprises:
piercing a plurality of peripheral outlets in a sealed capsule having a cup-shaped body, that has longitudinal central axis, and a sealing lid sealed onto the body, with the body of the capsule having its widest dimension at the lid, and with the peripheral outlets distributed along the periphery of the sealing lid; piercing the sealing lid of the capsule and introducing water in the capsule through the sealing lid; and centrifugally rotating the capsule in the beverage preparation device about the longitudinal central axis of the capsule to force the water to flow through the substance in a centrifugal flow path to form the beverage, leaving the capsule through the peripheral outlets; wherein the beverage preparation device comprises water feed means for introducing water in the capsule, means for centrifugally rotating the capsule to apply the centrifugal forces to force the water flow through the substance in a centrifugal flow path to prepare the beverage and referencing means for positioning and referencing the capsule in a removable manner in the device and in operational relationship with the water feed means and along the longitudinal central axis of rotation in the centrifugal rotating means; the referencing means being designed for receiving the capsule in a removable manner and for receiving the capsule and the referencing means comprising a water injection lid that engages against the capsule, is traversed by a water conduit and includes means for piercing at least one water inlet in the lid at the longitudinal central axis of the capsule, and with the referencing means comprising means for piercing the sealing lid of the sealed capsule to provide the peripheral outlets for enabling the beverage to leave the capsule and wherein the piercing means is formed of a series of needles on the injection lid to pierce the beverage outlets in the sealing lid.
