Embodiment Construction

[0045] now refer to Figure 1 to Figure 4 The first embodiment will be described with an example.

[0046] The device 1 of the invention generally comprises a centrifugal brewing unit 2 known "per se" for receiving and centrifuging a container, such as a removable capsule 17 which will be described in more detail hereinafter. The centrifugal brewing unit is designed for preparing a beverage such as coffee from both a beverage ingredient contained in the container and water sprayed into the container. The sprayed water interacts thoroughly with the beverage ingredients, such as by mixing, and obtains beverage extract which is forced out of the container at the periphery of the container by means of centrifugal force. The unit 2 is arranged in liquid communication with a liquid supply line 3 for supplying heated liquid, preferably water, from a reservoir 4 to the unit 2 . Liquid is circulated through line 3 by pump 5 . For example, the pump 5 may be any suitable type of pump,...

Abstract

Device for preparing a beverage from a beverage ingredient contained in a receptacle (17) by driving the receptacle in centrifugation comprising:-a holding part (16) arranged for holding the receptacle in a position enabling it to be driven in rotation along a longitudinal axis of rotation (I),-a liquid interfacing part (8) arranged for supplying water in the receptacle and/or extracting the beverage from the receptacle,-a collecting part (44) for collecting the beverage obtained by the interaction between the ingredient and water in the receptacle, wherein the holding part and liquid interfacing part (8, 16) are connected together by connection means in such a manner that these parts (8, 16) rotate together with the receptacle during centrifugation, wherein the connection means comprise at least a first engaging surface (48; 86) of the holding part (16) and a second engaging surface (23; 87) of the liquid interfacing part (8) engaged in contact together during connection in a manner preventing the holding part (16) and the liquid interfacing part (8) from moving away from each other, at least in the axial direction of rotation (I), and the connection means further comprising at least one mass of inertia (20, 21, 31; 80) arranged to be moveably connected to at least one of the parts (8, 16) with at least one degree of freedom in a least one radial direction for enabling the engagement forces to increase between the two engaging surfaces as a result of the increase of the centrifugal forces.

Description

technical field [0001] The present invention relates to the field of preparation of beverages by centrifugation. In particular, the present invention relates to a device for preparing a beverage such as coffee by brewing and extracting the beverage from a container by centrifugal action. Background technique [0002] It is known to prepare beverages by utilizing centrifugation. Its principle mainly includes providing beverage ingredients in the container, supplying liquid into the container and rotating the container at an increased speed to ensure the interaction between the liquid and the powder, while forming a pressure gradient of the liquid in the container; this pressure starts from the center of the container Gradual rise towards the periphery of the container. Extraction of the coffee mixture occurs as the liquid traverses the coffee bed and a liquid extract is obtained that flows out at the periphery of the container. [0003] WO2008 / 148601 describes one possible...
