Capsule for use in a food preparation machine
The present invention is directed to a capsule ( 11 ) for containing a food ingredient, adapted to be functionally inserted in the cavity of a food preparation machine ( 1 ), characterized in that said capsule ( 11 ) comprises at least one resilient portion ( 17, 19, 20, 21, 22, 23, 25, 26, 27, 29, 31, 33, 34, 35, 38 ) that is deformable when said capsule is inserted into the machine cavity, and/or when said cavity is closed, and in that at least one machine operational data is function of the elastic deformation properties of the resilient portion.
1. A food preparation system comprising:
an ingredient capsule; and
a food preparation machine adapted to cooperate functionally with the capsule, the food preparation machine comprising a cavity for receiving the capsule such that a food product is prepared in the capsule by injection of a fluid from the machine into the capsule, the cavity comprises a pressure sensitive portion adapted to cooperate with a capsule resilient deformable portion of the ingredient capsule to transmit operational data from the ingredient capsule to the machine, the data being a function of the elastic deformation properties of the capsule resilient deformable portion and comprises a setting value of a beverage preparation parameter selected from the group consisting of: water temperature, water pressure, volume of water to be pumped through the capsule, other machine operational data, and a combination thereof,
the capsule resilient deformable portion is configured to exert, upon deformation, a counterforce onto the food preparation machine, the pressure sensitive portion comprises a pressure sensor configured to measure the counterforce, the capsule resilient deformable portion having predetermined elastic deformation properties such that the counterforce corresponds to a predetermined value.
2. The food preparation system according to claim 1 , wherein the pressure sensitive portion is linked to a control board of the machine, such that cooperation between the pressure sensitive portion and the capsule resilient deformable portion is able to trigger an operation within the machine when the capsule resilient deformable portion transmits a mechanical deformation to the pressure sensitive portion, the operation being recognition switching the machine to a status selected from the group consisting of on, off, and setting a food preparation parameter.
3. The food preparation system according to claim 1 , wherein the pressure sensor is connected to an electrical switch.
4. The food preparation system according to claim 1 , wherein the food product is a liquid or semi-liquid product prepared within the capsule by the food preparation machine injecting a fluid to be mixed with the encapsulated ingredient, at a pressure of between 0.5 and 30 bar.
5. The food preparation system according to claim 1 , wherein the operational data that comprises the water temperature has a value ranging from about 12° C. to about 85° C.
