4. The consumable as claimed in claim 2 , wherein the at least one rigid wall portion of the housing is made from metal material or plastic material and shaped in a basically rotationally symmetric fashion defining an inlet end associated with the inlet portion, and an outlet end associated with the at least one primary outlet portion and the at least one secondary outlet portion, wherein the consumable comprises an inner housing that subdivides the housing into the at least two distinct chambers, wherein the at least one primary outlet portion is associated with the first chamber, and wherein the at least one secondary outlet portion is associated with the second chamber.

5. The consumable as claimed in claim 4 , wherein the internal flow control arrangement is arranged at a central portion of the inner housing and adjacent to the outlet end of the consumable.

6. The consumable as claimed in claim 4 , wherein the first chamber comprises a basically circular profile, wherein the second chamber comprises a basically annular profile that surrounds the profile of the first chamber, wherein the at least one primary outlet portion is arranged at a central portion of the outlet end, and wherein the at least one secondary outlet portion is arranged at a peripheral region of the outlet end.

7. The consumable as claimed in claim 1 , wherein the internal flow control arrangement comprises at least one flow control valve, particularly a pressure-dependent or flow-dependent flow control valve, which is operable based on internal fluid flow properties.

8. The consumable as claimed in claim 7 , wherein the internal flow control arrangement at least substantially blocks respective output flow when a flow parameter, particularly pressure or throughput, exceeds a defined threshold.

9. The consumable as claimed in claim 1 , wherein the internal flow control arrangement comprises a flow control valve that is made from resilient material, particularly from rubber or rubber-based material.

10. The consumable as claimed in claim 9 , wherein the flow control valve comprises a deflectable portion that selectively covers a respective flow passage of the consumable in the second state and exposes the flow passage in the first state.

11. The consumable as claimed in claim 10 , wherein the deflectable portion, in the absence of externals loads, is in a steady condition and at least partially bent away or lifted from respective flow conduits of the consumable that form the flow passage, and wherein an external load, caused by an increased flow or an increased pressure, deforms the deflectable portion when transitioning between the first state and the second state.

12. A processing unit for a dispenser for preparation of foodstuff products, the processing unit comprising:

a receiving cavity for receiving a consumable, the receiving cavity comprising at least a first receiving portion and at least a first fastening portion,

a sealing unit arranged to contact, at an inlet side, a first end of the consumable, such that an inlet portion of the consumable can be engaged in a basically pressure-tight manner,

an inlet engagement unit that is coupled to an inlet conduit through which pressurized water can be supplied, wherein the inlet engagement unit is operable to engage the inlet portion of the consumable to process a foodstuff product in the consumable,

an outlet engagement arrangement comprising:

a primary outlet engagement unit that is operable to engage at least one primary outlet portion of the consumable at an outlet side thereof to enable the processed foodstuff product to flow out of the consumable, and

an input flow steering arrangement that is operable to control flow parameters of an input flow to actuate an internal flow control arrangement of the consumable,

wherein the processing unit is arranged to process a consumable as claimed in any of the preceding claims so as to operate the internal flow control arrangement thereof.

13. The processing unit as claimed in claim 12 , further comprising:

a secondary outlet engagement unit that is implemented in the outlet engagement arrangement, wherein the secondary outlet engagement unit is operable to engage at least one secondary outlet portion of the consumable at the outlet side to enable the processed foodstuff product to flow out of the consumable, and

an engagement control unit that is operable to control the secondary outlet engagement unit such that the primary outlet engagement unit and the secondary outlet engagement unit engage the consumable in a time-displaced manner.

14. The processing unit as claimed in claim 13 , wherein the input flow steering arrangement and the engagement control unit are coupled to co-ordinate or synchronize an increase in the input flow and the engagement of the secondary outlet engagement unit.

15. The processing unit as claimed in claim 12 , further comprising a magnetic actuator unit, particularly an actuator coil, wherein the magnetic actuator unit is operable to exert an actuation force on a movable valve member of the internal flow control arrangement of the consumable to remotely operate the movable valve member between a first state and a second state to selectively permit or prevent a fluid flow from said at least one chamber.

16. A dispensing appliance for preparation of foodstuff products, particularly a beverage dispenser, the dispensing appliance comprising:

a water tank,

a pump unit for pressurizing water supplied from the water tank,

a heating unit for heating pressurized water, and

a processing unit as claimed in claim 12 .

17. A capsule-type, food substance containing consumable for use in a dispenser for preparation of foodstuff products, particularly a beverage, the consumable comprising:

a housing comprising at least one rigid wall portion that is impermeable to liquid,

an inlet portion arranged to enable pressurized water flow into the housing, when the consumable is inserted in a processing unit of the dispenser,

at least two distinct chambers arranged in the housing, and

an internal flow control arrangement operatively coupled with at least one of the at least two distinct chambers, wherein the internal flow control arrangement is operable to switch between:

a primary fluid flow through a first chamber of the at least two distinct chambers, and

a secondary fluid flow through a second chamber of the at least two distinct chambers,

wherein the internal flow control arrangement is configured to prevent the primary fluid flow from the first chamber so as to activate the secondary fluid flow from the second chamber.

18. The consumable as claimed in claim 17 , further comprising:

at least one primary outlet portion arranged to enable the primary fluid flow out of the housing, and

at least one secondary outlet portion arranged to enable the secondary fluid flow out of the housing,

wherein the first chamber is coupled to the at least one primary outlet portion, and the second chamber is coupled to the at least one secondary outlet portion.
