Embodiment Construction

[0093] like figure 1 As shown, the centrifuge system of the present invention includes a centrifuge unit 2 in which a centrifuge container 3 is arranged. The centrifuge container 3 may be a single-use capsule containing pre-portioned food ingredients (eg roasted and then ground coffee fraction). Before the capsule is inserted into the unit, the capsule is preferably sealed in an airtight manner to keep the food ingredients contained therein fresh. Alternatively, the centrifuge container 3 can be a refillable container of the centrifuge unit 2 .

[0094] The centrifugal separation unit 2 is connected to a drive device 5 comprising a rotary electric motor (electric motor) and a drive shaft. The drive device 5 is designed to rotate the drum (drum) of the centrifuge unit along the axis of rotation A, and thus to rotate the centrifuge unit 3 accommodated in the drum of the centrifuge unit 2 around the same axis of the centrifuge container. A spins. It should be noted that when ...

Abstract

A method for preparing a liquid comestible from a cell by passing liquid through the substance using centrifugal forces, wherein gas contained in the cell is controllably purged from the cell as liquid fills the cell.

Description

technical field [0001] The present invention relates to a method and system for preparing a liquid extract by passing water over centrifuged material contained in a container. More specifically, the present invention is useful in the preparation of beverage extracts such as coffee and the like. 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 a liquid such as hot water and ground coffee together for a defined period of time. The liquid is then passed through a screen on which the powder material is present. [0003] In a particular approach, eg in GB1506074, the container comprises a large opening to enable coffee to be filled into the capsule. Then, liquid is filled into the container and the container is rotated. Usually, the container is not completely filled with liquid, otherwise the liquid will leak through the la...
