ABSTRACT:
A cabinet and control system for maintaining a food product within a predetermined temperature range for a holding period of time not exceeding a predetermined maximum time. The cabinet comprises a housing having a front panel and a passageway opening at the front panel. The passageway is capable of receiving at least two containers of the food product. A temperature element positioned in said passageway maintains the passageway within the predetermined temperature range. A processing circuit tracks the amount of time each container of food product remains within the passageway. The processing circuit provides a signal output indicating which container has been within said passageway the longest and an alarm signal when either container remains within said passageway beyond said maximum time. A display positioned on said housing proximate to said passageway receives the said signal output and indicates which container has been within the passageway the longest. The display also receives the alarm signal and indicates which one of the containers has been within the passageway for a period of time exceeding the predetermined maximum time.
