Abstract

The present invention provides a method for effectuating temperature control in roller grill assembly. Some embodiments provide a roller grill assembly which provides enhanced measurement by utilizing temperature probes located in convective air streams generated in the roller tube. Certain embodiments also provide an improved method for maintaining of a food product temperature by utilizing an intermediate holding mode. Finally, certain embodiments provide improved current control by limiting the number of heating circuits of a food heater that may be simultaneously enabled such that the current draw does not exceed a maximum current draw.

Claims (17)

1. A method for maintaining a food product temperature in a food heater, the method comprising the steps of:

cooking a food product for a predetermined time in a cooking mode at a cooking temperature in a food heater,

exiting the cooking mode at the cooking temperature,

entering an intermediate holding mode for maintaining the food product at an intermediate holding temperature for an intermediate holding time period, wherein the intermediate holding temperature is less than the cooking temperature, and

thereafter entering a final holding mode for maintaining the food product at a final holding temperature for a final holding time period, wherein the final holding temperature is less than the intermediate holding temperature.

2. The method of claim 1 , wherein the food heater is a roller grill assembly.

3. The method of claim 1 , wherein the intermediate holding temperature is an average of the cooking temperature and the final holding temperature.

4. The method of claim 1 , wherein the intermediate holding time period is fixed.

5. The method of claim 1 , wherein the intermediate holding mode comprises the steps of:

setting an intermediate holding temperature,

setting an intermediate holding time,

comparing an elapsed time to the intermediate holding time, and

terminating the intermediate holding mode if the elapsed time exceeds the intermediate holding time.

6. The method of claim 4 , wherein the intermediate holding time period is 10 minutes.

7. The method of claim 5 , wherein the intermediate holding mode further comprises the steps of:

measuring a temperature of the food product, directly or indirectly, and comparing the temperature to the intermediate holding temperature, and

enabling a heating unit of the food heater if the measured temperature of the food product is less than the intermediate holding temperature, and disabling the heating unit of the food heater if the measured temperature is greater than the intermediate holding temperature.
