Abstract

A foaming machine providing a fluid foam and/or a food product foam, the machine being configured to receive an in-line heating device, the in-line heating device includes a primary heating unit and a heating cartridge. The heating cartridge includes an inner heating path. A system for providing a hot fluid foam and/or a hot food product foam.

First claim

The invention claimed is:

1. An in-line heating device for heating at least one composition selected from the group consisting of a fluid, a food product, a fluid foam, and a food foam, the in-line heating device comprising:
a primary heating unit; and
a heating cartridge comprising:
an inner heating path configured to circulate the at least one composition;
a heating insert with an inner shape defining the inner heating path, wherein the heating insert is made of a thermally conductive material;
an outer insert made of an electrically conductive material and configured to be inductively heatable by an oscillating magnetic field provided by the primary heating unit, and wherein the outer insert as a sleeve surrounding an outer periphery of the heating insert,
wherein the inner heating path is arranged inside the outer insert so that the at least one composition is heated while circulating through the inner heating path and before being delivered from the in-line heating device; and
a nozzle housing arranged to externally surround both the heating insert and the outer insert, the nozzle housing configured to be removable to thereby remove the heating cartridge from the rest of the in-line heating device, and
wherein an outlet of the nozzle housing is configured to dispense the at least one composition, that has been heated, into a cup.

2. The in-line heating device of claim 1 , wherein a distance between the primary heating unit and the outer insert is configured for heating the at least one composition.

3. The in-line heating device of claim 1 , wherein the primary heating unit and the outer insert are distanced by a separated heating space of a dimension such that the outer insert is at least partially positioned inside the oscillating magnetic field provided by the primary heating unit.

4. The in-line heating device of claim 1 , wherein the primary heating unit comprises a primary induction coil.

5. The in-line heating device of claim 1 , wherein the heating cartridge has an external cylindrical shape, the outer insert is configured as a cylindrical sleeve matching an external cylindrical shape of the heating cartridge.

6. The in-line heating device of claim 1 , wherein the heating insert is made of aluminum.

7. The in-line heating device of claim 1 , wherein the heating cartridge is disposable after each use.

8. An in-line heating device for heating at least one composition selected from the group consisting of a fluid, a food product, a fluid foam, and a food foam, the in-line heating device comprising:
a primary heating unit; and
a heating cartridge comprising:
an inner heating path configured to circulate the at least one composition;
a heating insert with an inner shape defining the inner heating path; and
an outer insert made of an electrically conductive material and configured to be inductively heatable by an oscillating magnetic field provided by the primary heating unit, and wherein the outer insert is a sleeve surrounding an outer periphery of the heating insert, and wherein the heating insert comprises at least two complementary shaped bodies, wherein the at least two complementary shaped bodies are reversibly joined to each other to allow assembly and disassembly of the at least two complementary shaped bodies;
wherein the inner heating path is arranged inside the outer insert so that the at least one composition is heated while circulating through the inner heating path and before being delivered from the in-line heating device, and wherein the at least two complementary shaped bodies of the heating insert configure internally the heating path when brought together;
a nozzle housing arranged to externally surround both the heating insert and the outer insert, the nozzle housing configured to be removable to thereby remove the heating cartridge from the rest of the in-line heating device, and
wherein an outlet of the nozzle housing is configured to dispense the at least one composition, that has been heated, into a cup.

9. An in-line heating device for heating at least one composition selected from the group consisting of a fluid, a food product, a fluid foam, and a food foam, the in-line heating device comprising:
a primary heating unit; and
a heating cartridge comprising:
an inner heating path configured to circulate the at least one composition;
a heating insert with an inner shape defining the inner heating path;
an outer insert made of an electrically conductive material and configured to be inductively heatable by an oscillating magnetic field provided by the primary heating unit, and wherein the outer insert is a sleeve surrounding an outer periphery of the heating insert,
wherein the inner heating path is arranged inside the outer insert so that the at least one composition is heated while circulating through the inner heating path and before being delivered from the in-line heating device; and
a nozzle housing arranged to externally surround both the heating insert and the outer insert, the nozzle housing configured to be removable to thereby remove the heating cartridge from the rest of the in-line heating device, and
wherein an outlet of the nozzle housing is configured to dispense the at least one composition, that has been heated, into a cup.

10. The in-line heating device of claim 9 , wherein the nozzle housing is made of a non-conductive material.

11. A system for providing a hot fluid foam and/or a hot food product foam, the system comprising:
the in-line heating device of claim 1 ; and
a foaming machine providing a fluid foam and/or a food product foam, wherein the foaming machine is configured to receive the in-line heating device.

12. The system of claim 11 , wherein the foaming machine comprises a temperature sensor arranged to have close contact with the outer insert of the heating cartridge.

13. A system for providing a hot fluid foam and/or a hot food product foam, the system comprising:
the in-line heating device of claim 8 ; and
a foaming machine providing a fluid foam and/or a food product foam, wherein the foaming machine is configured to receive the in-line heating device.

14. The system of claim 13 , wherein the foaming machine comprises a temperature sensor arranged to have close contact with the outer insert of the heating cartridge.

15. A system for providing a hot fluid foam and/or a hot food product foam, the system comprising:
the in-line heating device of claim 9 ; and
a foaming machine providing a fluid foam and/or a food product foam, wherein the foaming machine is configured to receive the in-line heating device.

16. The system of claim 15 , wherein the foaming machine comprises a temperature sensor arranged to have close contact with the outer insert of the heating cartridge.

17. A method comprising:
foaming a fluid and/or a food product;
heating the fluid and/or the food product using the system of claim 11 ; and
dispensing the heated composition into a cup.

18. A method comprising:
foaming a fluid and/or a food product;
heating the fluid and/or the food product using the system of claim 13 ; and
dispensing the heated composition into a cup.

19. A method comprising:
foaming a fluid and/or a food product;
heating the fluid and/or the food product using the system of claim 15 ; and
dispensing the heated composition into a cup.
