Abstract
A device for preparing a beverage from a beverage ingredient contained in a receptacle by driving the receptacle in centrifugation is disclosed, along with methods for using same.
Claims15
A device for preparing a beverage from a beverage ingredient contained in a receptacle by driving the receptacle in centrifugation comprising:
- a receptacle holder arranged for holding the receptacle in a position enabling it to be driven in rotation along a longitudinal axis of rotation, the receptacle holder comprising a support portion and a side wall extending from the support portion,
- a liquid interface arranged for engaging against the receptacle and for supplying water in the receptacle and/or extracting the beverage from the receptacle, wherein the liquid interface comprises a base for engaging the receptacle and an injector for supplying liquid to the receptacle,
- a collector for collecting the beverage obtained by the interaction between the ingredient and water in the receptacle,
- wherein the receptacle holder and the liquid interface are connected together at least during rotation in such a manner that these parts rotate together with the receptacle during centrifugation, and wherein the receptacle holder and liquid interface are connected via at least a first engaging surface of one of the receptacle holder or the liquid interface and a second engaging surface connected to the other one of the receptacle holder or the liquid interface, wherein the first and second engaging surfaces are adapted to be engaged in contact together at least during rotation of the device in a manner preventing the receptacle holder and the liquid interface from moving away from each other, at least in the axial direction of rotation, and
- wherein the second engaging surface is arranged to be moveably connected to the other one of the parts with at least one degree of freedom at least about a pivoting axis to allow engagement forces between the two engaging surfaces to increase as a result of the increase of the centrifugal forces.

A method for preparing a beverage from a beverage ingredient contained in a receptacle, comprising the steps of:
- placing the receptacle in a receptacle holder, wherein the receptacle holder comprises a support portion and a side wall extending from the support portion,
- engaging a liquid interface against the receptacle, wherein the liquid interface comprises a base for engaging the receptacle and an injector for supplying liquid to the receptacle,
- supplying water in the receptacle through the injector of the liquid interface,
- driving the receptacle in rotation along a longitudinal axis of rotation by rotating the receptacle holder and the liquid interface together with the receptacle,
- collecting the beverage obtained by the interaction between the ingredient and water in the receptacle by a collector,
- wherein the receptacle holder and the liquid interface are connected together at least during rotation in such a manner that these parts rotate together with the receptacle during centrifugation, wherein the receptacle holder and the liquid interface are connected via at least a first engaging surface of one of the receptacle holder or the liquid interface and a second engaging surface connected to the other one of the receptacle holder or the liquid interface, wherein the first and second engaging surfaces engage in contact together at least during rotation of the device in a manner preventing the receptacle holder and the liquid interface from moving away from each other, at least in the axial direction of rotation, and
- wherein the second engaging surface is arranged to be moveably connected to the other one of the parts with at least one degree of freedom at least about a pivoting axis being substantially in parallel to the longitudinal axis of rotation to increase the engagement forces between the two engaging surfaces as a result of the increase of the centrifugal forces.
