Embodiment Construction

[0068] Such as figure 1 with 2 As shown in , the preferably single-use capsule 1 of the present invention generally comprises a concave body 2 on which a perforable membrane 3 is sealed. The membrane 3 is sealed to the peripheral edge 4 of the concave body 2 at a sealing annular portion 5 . The rim 4 may extend outwards to form a small annular seal of between about 2-5mm. The concave body comprises a bottom wall 6 and a side wall 7 which preferably widens in the direction of the large open end of the concave body opposite the bottom wall. The concave body is preferably rigid or semi-rigid. The concave body may be formed from food grade plastic such as polypropylene with a gas barrier layer such as EVOH and the like or aluminum alloy or a laminate of plastic and aluminum alloy. The membrane 3 can be made of a thinner material such as a plastic film also comprising a barrier layer or an aluminum alloy or a combination of plastic and aluminum alloy. The membrane typically ha...

Abstract

The present invention relates to a liquid food preparation system for preparing a liquid food from a food substance comprising a device and a capsule removably insertable in the device, by passing water through the substance in the capsule, comprising a water injection head for injecting water in the capsule and a capsule holder for holding the capsule in the device, means for driving the capsule in centrifugation, perforating means which are configured relative to the capsule in the device to open outlets at the periphery of the capsule, a capsule comprising a delivery pierceable membrane, wherein said perforating means, are suited to be engaged through the membrane for forming with the perforated membrane a filtering means for retaining solid particles in the capsule and orifices in the membrane for enabling the centrifuged liquid to leave the capsule.

Description

technical field [0001] The present invention relates to a capsule system and method for preparing a liquid food product from a food material contained in a container by passing water through the food material using centrifugal force. Background technique [0002] It is known to prepare beverages in which a mixture comprising brewed coffee and coffee powder is separated by centrifugal force. This mixture is obtained by bringing hot water and ground coffee together for a defined period of time. The water is then forced through a sieve on which the powdered material sits. [0003] Existing systems involve placing coffee grounds in a container, which is usually a non-detachable part of the machine, as described in EP0367600B1. This device has a number of disadvantages. First, the coffee powder must be properly dosed into the container manually. Second, the centrifuged coffee waste dries out and it must be removed by scraping the surface of the container. As a result, coffee...
