What is claimed is:

1. A pan oiler for depositing cooking oil into a baking pan that has at least one product mold, the pan oiler comprising:

a conveyor assembly configured to carry the baking pan through the pan oiler; and

an electrostatic oiler assembly, wherein the electrostatic oiler assembly comprises:

a charge assembly;

an oil delivery assembly; and

and at least one injector assembly, wherein the at least one injector assembly comprises:

a valve body;

a plunger extending into the valve body, wherein the plunger is retractable and conductive, and wherein the plunger is in electrical contact with the charge assembly; and an actuator operably connected to the plunger to lift the plunger when the actuator is energized.

2. The pan oiler of claim 1, wherein the injector assembly further comprises an oil reservoir within the valve body, wherein the oil reservoir is in fluid communication with the oil delivery system.

3. The pan oiler of claim 2, wherein the valve body comprises a valve seat in fluid communication with the oil reservoir and wherein the actuator is configured to lift the plunger off the valve seat with the actuator is energized.

4. The pan oiler of claim 3, wherein the injector assembly further comprises a deposition needle connected to the valve body adjacent the valve seat.

5. The pan oiler of claim 1, wherein the injector assembly further comprises an isolator connected between the actuator and the plunger.

6. The pan oiler of claim 1, wherein the actuator comprises a motor selected from the group consisting of solenoids, pneumatic pistons and piezo electric devices.

7. The pan oiler of claim 1, wherein the oil delivery system comprises: an oil tank;

tubing connected to the injector assembly; and

a pump configured to move cooking oil from the oil tank to the injector assembly under pressure.

8. The pan oiler of claim 7, wherein the pump is configured to pressurize the cooking oil to a pressure of between 0.5 psi and 30 psi.

9. The pan oiler of claim 8, wherein the pump is configured to pressurize the cooking oil to between 2 psi and 3 psi.

10. A pan oiler for depositing cooking oil into a baking pan that has a plurality of product molds arranged in one or more rows, the pan oiler comprising: a conveyor assembly configured to carry the baking pan through the pan oiler; and

an electrostatic oiler assembly, wherein the electrostatic oiler assembly comprises:

a charge assembly;

an oil delivery assembly; and

a plurality of injector assemblies, wherein each of the plurality of injector assemblies comprises:

a valve body;

a plunger extending into the valve body, wherein the plunger is in electrical contact with the charge assembly; and an actuator operably connected to the plunger to lift the plunger when the actuator is energized.

11. The pan oiler of claim 10, wherein each of the plurality of injector assemblies corresponds to a separate one of the plurality of product molds in a single row of the baking pan.

12. The pan oiler of claim 10, wherein the injector assembly further comprises an oil reservoir within the valve body, wherein the oil reservoir is in fluid communication with the oil delivery system.

13. The pan oiler of claim 12, wherein the valve body comprises a valve seat in fluid communication with the oil reservoir.

14. The pan oiler of claim 13, wherein the injector assembly further comprises a deposition needle connected to the valve body adjacent the valve seat.

15. The pan oiler of claim 14, wherein the deposition needle is hollow.

16. The pan oiler of claim 10, wherein the injector assembly further comprises an isolator connected between the actuator and the plunger.

17. The pan oiler of claim 10, wherein the actuator comprises a motor selected from the group consisting of solenoids, pneumatic pistons and piezo electric devices.

18. The pan oiler of claim 1, wherein the oil delivery system comprises: an oil tank;

tubing connected to the injector assembly; and

a pump configured to move cooking oil from the oil tank to the injector assembly at a pressure of between 0.5 psi and 30 psi.

19. An electrostatic oiler assembly configured to accurately deposit a fluid within a product mold of a baking pan, wherein the electrostatic oiler assembly comprises:

a charge assembly;

an oil delivery assembly; and

at least one injector assembly connected to the charge assembly and the oil delivery assembly, wherein the at least one injector assembly comprises means for selectively releasing positively charged and pressurized cooking oil above the product mold.

20. The electrostatic oiler of claim 19, wherein the charge assembly comprises a ground contact proximate the product mold of the baking pan.
