Method for preparing a food liquid contained in a capsule by centrifugation and device adapted for such method

摘要

A method for preparing a food liquid from a food substance contained in a single-use capsule by passing water through the substance. The method includes centrifugally rotating the capsule while introducing water therein to pass the water through the substance to form the food liquid, opening at least one liquid delivery outlet in the capsule which is peripherally offset relative to the center of the capsule, and delivering the food liquid from the at least one liquid delivery outlet to dispense the beverage.

1. A method for preparing a food liquid from a food substance contained in a sealed, single-use capsule, in a liquid food preparation device comprising a water injection head for injecting water in the capsule and a capsule holder for holding the capsule in the device; the capsule configured for removable insertion in the capsule holder and comprising a cup shaped body covered by a sealing lid that has a peripheral rim by passing water through the substance, the method comprising:
piercing the sealing lid of the sealed capsule by a piercing member of a water injector of the water injection head and introducing water by the water injector into a generally central portion of the capsule, forming a series of liquid delivery outlets by a series of additional piercing members in the sealing lid of the capsule at the periphery of the sealing lid near the peripheral rim of the body, after the outlets are formed in the lid of the capsule, centrifugally rotating the capsule about its central axis for passing water outwardly from the generally central portion through the substance and then toward the liquid delivery outlets of the lid to form the food liquid, delivering the food liquid as several streams of liquid from the delivery outlets formed in the lid of the capsule, and passing the food liquid delivered from the capsule through a restriction valve and wherein the restriction valve opens when a certain pressure is exerted by centrifuged food liquid on the restriction valve.
