- 9. The apparatus of claim 7, wherein the conveyor is a porous conveyor.
- 10. The apparatus of claim 1, wherein the controller and the timer form an integral unit.
- 11. The apparatus of claim 1, wherein the temperature sensor is a thermocouple.
- 12. The apparatus of claim 1, wherein the temperature sensor is a remote infra-red sensor.
- 13. The apparatus of claim 1, wherein the chilled water source is located in the interior portion of the chamber.
- 14. The apparatus of claim 1, wherein the chilled water source is not located in the interior portion of the chamber.
- 15. The apparatus of claim 1, wherein the steam generator includes a first set of plates and a second set of plates in electronic communication with the power source.
- 16. The apparatus of claim 1, wherein the water inlet valve is in fluid communication with an orifice.
- 17. The apparatus of claim 1, wherein the suspension element is a grated floor.
- 18. The apparatus of claim 1, wherein the chamber includes at least one drain pan.
- 19. The apparatus of claim 1, wherein the chamber includes a bonnet and a base unit.
- 20. The apparatus of claim 19, wherein the bonnet has a steam inlet and at least one venting handle for regulation of steam pressure within the bonnet.
- 21. The apparatus of claim 19, wherein the base unit has a bottom and includes steam outlet pipes located along the bottom.
- 22. A method for microbial intervention and pasteurizing a food processing equipment having an outer surface comprising the steps of:placing the food processing equipment in a chamber; adding steam to the chamber; sensing a measured temperature of the outer surface; adding steam to the chamber if the measured temperature of the outer surface is less than about 74° C., otherwise; starting a timer having a timeout period of about 60 seconds; adding steam to the chamber until the timeout period occurs; stopping the addition of steam to the chamber.
- 23. The method of claim 22, including the step of bathing the outer surface with water including a sanitizing agent.
- 24. The method of claim 22, wherein the step of sensing a measured temperature of the outer surface is accomplished using a thermocouple placed in proximity to the outer surface.
- 25. The method of claim 22, wherein the step of sensing a measured temperature of the outer surface is accomplished using a remote infra-red sensor.
- 26. A method for microbial intervention and pasteurizing a food processing equipment having an outer surface comprising the steps of:placing the food processing equipment in a chamber; adding steam to the chamber; sensing a measured temperature of the outer surface; adding steam to the chamber until the measured temperature of the outer surface is greater than a first preselected temperature; starting a timer having a timeout period of about 60 seconds; adding steam to the chamber until the timeout period occurs, or the measured temperature of the outer surface becomes greater than a second preselected temperature, whichever occurs first; and bathing the outer surface with water for about 60 seconds after the timer reaches the timeout period.
- 27. The method of claim 26, wherein the water includes a sanitizing agent.
- 28. The method of claim 26, wherein the sanitizing agent is a food and equipment grade sanitizer.
- 29. The method of claim 26, wherein the step of sensing a measured temperature of the outer surface is accomplished using a thermocouple placed in proximity to the outer surface.
- 30. The method of claim 26, wherein the step of sensing a measured temperature of the outer surface is accomplished using a remote infra-red sensor.
- 31. The method of claim 26, wherein the first preselected temperature is about 74° C.
- 32. The method of claim 26, wherein the second preselected temperature is about 84° C.
- 33. A method for microbial intervention and pasteurizing a food processing equipment having an outer surface comprising the steps of:adding steam to a steam tunnel; sensing a measured temperature of the outer surface; adding steam to the steam tunnel until the measured temperature of the outer surface is greater than a first preselected temperature; starting a timer having a timeout period of about 60 seconds; adding steam to the steam tunnel until the timeout period occurs, or the measured temperature of the outer surface becomes greater than a second preselected temperature, whichever occurs first.
- 34. The method of claim 33, including the step of placing the processing equipment on a roller conveyor within the steam tunnel.
