Flavor blending system

1. A system for forming a frozen flowable confection, comprising:

a frozen consumable freezer; and

a flavor injection and blending assembly attached to the frozen consumable freezer;

wherein the flavor injection and blending assembly includes a blend cartridge having an inner surface defining a confection passageway extending from an inlet end to an outlet end and having a first mixing vane positioned therein;

wherein a lower portion of the inner surface tapers inwardly near the outlet end of the confection passageway to form a nozzle.

2. The system of claim 1 , wherein the first mixing vane has a width and the outlet end of the confection passageway has a width less than that of the first mixing vane.

3. The system of claim 1 , wherein the outlet end of the confection passageway is narrower than any other area of the confection passageway in the flavor injection and blending assembly.

4. The system of claim 1 , wherein the outlet end of the confection passageway has a circular cross-section.

5. The system of claim 1 , comprising a cap attachable to the outlet end of the flavor injection and blending assembly and having an opening with a non-circular cross-section.

6. The system of claim 1 , wherein a screen is positioned between the first mixing vane and the outlet end of the confection passageway.

7. The system of claim 6 , wherein a bottom end of the first mixing vane is spaced from a top surface of the screen.

8. The system of claim 1 , comprising a second mixing vane transverse to and welded to the first mixing vane.

9. The system of claim 8 , wherein the first mixing vane has a lower portion defining a slot with a lower portion of the second mixing vane received therein; and

wherein the second mixing vane has an upper portion defining a slot with an upper portion of the first mixing vane received therein.

10. The system of claim 9 , wherein the first mixing vane has an elongate opening extending in a first direction relative to a center of the first mixing vane; and

wherein the second mixing vane has an elongate opening extending in a second direction relative to a center of the second mixing vane.

11. The system of claim 10 , wherein the elongate opening of the first mixing vane extends upwardly and radially outward from the center of the first mixing vane; and

wherein the elongate opening of the second mixing vane extends downwardly and radially outward from the center of the second mixing vane.

12. The system of claim 1 , comprising a sanitizing system having a sanitizer tank and pump configured to provide water to the flavor injection and blending assembly.

13. A system for forming a frozen flowable confection, comprising:

a frozen consumable freezer; and

a flavor injection and blending assembly attached to the frozen consumable freezer;

wherein the flavor injection and blending assembly includes a blend cartridge having an inner surface defining a confection passageway extending from an inlet end to an outlet end and having a rotatable mixing vane assembly positioned therein;

wherein the rotatable mixing vane assembly comprises a first mixing vane and a second mixing vane transverse to one another; and

wherein the first mixing vane and second mixing vane are welded to one another.

14. The system of claim 13 , wherein the first mixing vane has a lower portion defining a slot with a lower portion of the second mixing vane received therein; and

wherein the second mixing vane has an upper portion defining a slot with an upper portion of the first mixing vane received therein.

15. The system of claim 13 , wherein the first mixing vane has an elongate opening extending in a first direction relative to a center of the first mixing vane; and

wherein the second mixing vane has an elongate opening extending in a second direction relative to a center of the second mixing vane.

16. The system of claim 15 , wherein the elongate opening of the first mixing vane extends upwardly and radially outward from the center of the first mixing vane; and

wherein the elongate opening of the second mixing vane extends downwardly and radially outward from the center of the second mixing vane.

17. The system of claim 13 , wherein an outer edge of the first mixing vane and an outer edge of the second mixing vane each engage a gear ring having a plurality of gear teeth extending around a periphery thereof.

18. A system for forming a frozen flowable confection, comprising:

a frozen consumable freezer;

a flavor injection and blending assembly attached to the frozen consumable freezer, the flavor injection and blending assembly having an injector head having a flavor tube for supplying flavor syrup into a passageway of the flavor injection and blending assembly; and

a sanitizing system having a sanitizer tank and pump configured to provide water to the a flavor injection and blending assembly through:

(a) a water line extending to a spout adaptor of the flavor injection and blending assembly, the spout adaptor positioned between a spout of the frozen consumable freezer and the injector head of the flavor injection and blending assembly;

(b) a water line extending to the injector head of the flavor injection and blending assembly; and/or

(c) a water flush line connected to a syrup line extending to the injector head and communicating with the flavor tube.

19. The system of claim 18 , wherein the sanitizing system provides water to the flavor injection and blending assembly automatically at a predetermined time of day or after a predetermined period of time.

20. The system of claim 18 , wherein the sanitizing system has a water flush line connected to a syrup line extending to the injector head and communicating with the flavor tube.
