Embodiment Construction

[0066] Such as figure 1 and figure 2 As shown, the preferred single-use capsule 1 of the invention comprises a disc-shaped body 2 on which a sealing foil or membrane 3 is sealed. The sealing foil 3 is sealed on the periphery 4 of the body in a sealing ring 5 . The peripheral edge 4 may extend outwards to form a small annular seal of about 2-5 mm. The disc-shaped body comprises a bottom wall 6 and a side wall 7 which preferably widens in the direction of the large open end of the body opposite the bottom wall. The disc-shaped body is preferably rigid or semi-rigid. The disc-shaped body can be formed of food-grade plastic (such as polypropylene) or aluminum alloy or a composite of plastic and aluminum alloy with a gas barrier layer (such as EVOH, etc.). The sealing foil 3 can be made of a thinner material, eg a plastic laminate which also includes a shielding layer or an aluminum alloy or a combination of plastic and aluminum alloy. The sealing wall typically has a thickne...

Abstract

A method for preparing a food liquid from a food substance contained in a single-use capsule by passing water through the substance, comprises: driving the capsule in centrifugal rotation while introducing water in the centre of capsule, passing water through the substance to form a food liquid, piercing at least one liquid delivery outlet in the capsule, wherein piercing is obtained, at least partially, by the effect of the pressure rising in the capsule as a result of the centrifugation.

Description

technical field [0001] The present invention relates to a device and a capsule system for preparing a food liquid from a food substance contained in a container by passing water through the substance using centrifugal force. Background technique [0002] It is known to prepare beverages in which the mixture consisting of brewed coffee and coffee powder is separated using centrifugal force. This mixture is obtained by mixing hot water and ground coffee together for a defined period of time. The water is then forced through a screen on which the powdered material is present. [0003] Existing systems consist in placing the ground coffee in a container which is usually a non-removable part of the machine, for example as in EP 0367 600 B1. Such devices have a number of disadvantages. First, the ground coffee must be manually portioned in the container properly. Second, the centrifuged coffee waste dries out and it must be removed by scraping the surface of the container. Th...
