System for multi-ingredient beverage preparation from various container types
A beverage preparation machine includes a fluid system comprising a fluid source, a pump, a heating element, at least two container holders adapted for receiving ingredient containers, and a control unit for controlling the fluid system to prepare a beverage by mixing fluid with the beverage ingredient contained in the containers to produce a mixed beverage component in each of the containers. The control unit is further arranged to dispense part or whole of the mixed components sequentially or simultaneously to produce the beverage. The container holders differ from one another for holding containers of different sizes and/or types. Separate fluid injection interfaces have different structural and kinematic configurations and are arranged for independently delivering fluid in one of the corresponding ingredient containers. Each interface is connected to the fluid system and adapted to a different container.
1. A beverage preparation machine comprising a fluid system comprising a fluid source, a fluid pump, a fluid heating element, a first container holder and a second container holder, wherein each of the first and second container holders are adapted for receiving a corresponding first beverage ingredient container and second beverage ingredient container, and
a control unit arranged for controlling the fluid system to prepare a beverage by mixing fluid with the beverage ingredients contained in the first and second beverage ingredient containers to produce a beverage component in each of the first and second beverage ingredient containers and to dispense at least a portion of each of the beverage components of the first and second beverage ingredient containers at least sequentially in a controlled manner to produce the beverage,
wherein the first and second container holders differ from each other for holding the first and second beverage ingredient containers of different sizes and types, and
wherein the beverage preparation machine further comprises a first fluid delivery interface and a second fluid delivery interface which are separate and respectively arranged for independently delivering the fluid in the corresponding first and second beverage ingredient containers, each of the first and second fluid delivery interfaces being connected to the fluid system and being adapted to the different first and second beverage ingredient containers,
wherein the separate first and second fluid delivery interfaces have different structural and kinematic configurations,
wherein the different kinematic configurations have different relative movements between the first and second beverage ingredient containers and the corresponding first and second fluid delivery interfaces, and
wherein the control unit is adapted to manage the functioning of the first and second fluid delivery interfaces at least sequentially according to the type of beverage to produce and is adapted to control the fluid system for each of the separate first and second fluid delivery interfaces in a different manner such that at least one of a fluid flow rate, a fluid pressure, or a fluid volume of the fluid that is delivered in the first beverage ingredient container differs from the fluid delivered in the second beverage ingredient containers.
2. The beverage preparation machine according to claim 1 , wherein the first container holder is adapted to receive a first beverage ingredient container comprising a pod containing roast and ground coffee and the second container holder is adapted to receive a second beverage ingredient container comprising a sachet containing a soluble powder or a liquid concentrate.
3. The beverage preparation machine according to claim 2 , wherein the first fluid delivery interface comprises a shower plate and is configured to distribute the fluid over at least a fluid-permeable portion of the pod and the second fluid delivery interface comprises a fluid injection needle configured to pierce through a wall of the sachet for injection of fluid.
4. The beverage preparation machine according to claim 2 , wherein walls of the pod containing roast and ground coffee are made of a pierceable, rupturable, or tearable laminated composite film with moisture and oxygen barrier properties, and
the sachet containing a soluble powder or a liquid concentrate comprises a pierceable, rupturable, or tearable film pouch sealed around at least one spout, the at least one spout comprising at least one fluid injection inlet and at least one beverage dispensing outlet.
5. The beverage preparation machine according to claim 1 , wherein the fluid pump integrates a by-pass valve connecting a pump outlet to a pump inlet, in order to modulate the flow rate and the pressure.
6. The beverage preparation machine according to claim 1 , wherein at least one of the separate first and second fluid delivery interfaces is connected to the fluid system through a type of a releasable fluidic connection configured to be detached from the beverage preparation machine and replaced by another type of separate fluid delivery interface having the same type of a releasable fluidic connection.
7. The beverage preparation machine according to claim 1 , further comprising a fluid-cooling element.
8. The beverage preparation machine according to claim 1 , wherein the separate first and second fluid delivery interfaces differ by at least one structural element that involves at least one kinematic movement of rotation or translation.
9. The beverage preparation machine according to claim 1 , wherein a headspace in at least one of the first and second beverage ingredient containers is less than 20%.
10. The beverage preparation machine according to claim 1 , wherein the control unit is further arranged to dispense at least a portion of each of the beverage components of the first and second beverage ingredient containers simultaneously in a controlled manner to produce the beverage, and
wherein the control unit is adapted to manage the functioning of the first and second fluid delivery interfaces simultaneously according to the type of beverage to produce and is adapted to control the fluid system for each of the separate first and second fluid delivery interfaces in a different manner such that at least one of a fluid flow rate, a fluid pressure, or a fluid volume of the fluid that is delivered in the first beverage ingredient container differs from the fluid delivered in the second beverage ingredient containers.
