Liquid food dispenser system and method
A system and method for dispensing fluids is introduced. A preferred embodiment comprises a sealed tank, a bag containing fluid inside the sealed tank, an outlet for dispensing the liquid in the bag, and a pressure generating device to create pressure in the sealed tank.
1. A method for operating a nozzle, the nozzle comprising a nozzle tip with a tapered cavity, a water inlet, and a plunger with a tapered end disposed within the nozzle tip, the method comprising:
rotating the nozzle tip in a first rotational direction to move the plunger in a first axial direction, thereby opening the nozzle, wherein the tapered cavity prevents the plunger from extending beyond the nozzle tip;
dispensing a liquid, introducing a flow of water while dispensing the liquid; and
rotating the nozzle tip in a second rotational direction opposite the first rotational direction to move the plunger in a second axial direction opposite the first axial direction, thereby closing the nozzle and forming a liquid tight seal.
2. The method of claim 1 , wherein rotating the nozzle tip further comprises activating a nozzle drive coupled to the nozzle tip.
3. The method of claim 2 , wherein activating the nozzle drive further comprises running a motor coupled to the nozzle drive.
4. The method of claim 2 , comprising stopping the flow of water when closing the nozzle.
5. The method of claim 2 , comprising stopping the flow of water at a time after closing the nozzle.
6. The method of claim 5 , further comprising washing the nozzle after closing the nozzle.
7. A method of operating a nozzle, the method comprising:
rotating a nozzle tip around a first axis a first time, wherein the rotating the nozzle around the first axis engages a nozzle tip rotation track located with a nozzle plunger rotation pin to move a plunger along the first axis in a first direction, wherein the plunger is guided by slide stop tabs that prevent rotational motion; and
rotating the nozzle tip around the first axis a second time, wherein the rotating the nozzle tip around the first axis the second time moves the plunger along the first axis in a second direction opposite the first direction;
dispensing a liquid through the nozzle after the rotating the nozzle tip the first time and before the rotating the nozzle tip the second time; and
flowing water through a water inlet in a nozzle drive, wherein the flowing water through the water inlet is performed while dispensing the liquid.
8. The method of claim 7 , wherein the nozzle tip comprises a tapered cavity and the plunger comprises a tapered end disposed within the tapered cavity prior to the rotating the nozzle tip around the first axis the first time.
9. The method of claim 7 , wherein the rotating the nozzle tip the first time further comprises activating the nozzle drive coupled to the nozzle tip.
10. The method of claim 9 , wherein the activating the nozzle drive further comprises running a motor coupled to the nozzle drive.
11. The method of claim 9 , further comprising stopping the flowing water after the rotating the nozzle tip around the first axis the second time.
12. A method of operating a nozzle, the method comprising:
moving a plunger located within a nozzle tip in a first direction, wherein the nozzle tip remains stationary in the first direction during the moving the plunger, wherein the plunger comprises a central portion and slide stop tabs extending outwards from the central portion, wherein the moving the plunger separates a tapered portion of the plunger from a tapered portion of the nozzle tip;
dispensing a liquid after the moving the plunger has begun; and
dispensing water at the same time as the dispensing the liquid.
13. The method of claim 12 , wherein the nozzle tip moves in a second direction during the moving the plunger.
14. The method of claim 13 , wherein the nozzle tip comprises a nozzle tip rotation track and the plunger comprises a plunger rotation pin, and wherein the nozzle tip rotation track moves the nozzle tip in the second direction.
15. The method of claim 13 , further comprising:
rotating the nozzle tip after the moving the plunger, wherein the nozzle tip remains stationary in the first direction during the rotating the nozzle tip; and
moving the plunger within the nozzle tip, wherein the moving the plunger moves the plunger in a second direction opposite the first direction.
16. The method of claim 15 , further comprising stopping the dispensing water after the rotating the nozzle tip.
17. The method of claim 12 , wherein the moving the plunger further comprises activating a nozzle drive coupled to the nozzle tip.
18. The method of claim 17 , wherein the activating the nozzle drive further comprises running a motor coupled to the nozzle drive.
