Abstract
A food warming cabinet keeps food warm and on display in serving trays using infrared heaters instead of hot water. The infrared heaters are located below the trays and direct IR at the trays. In an alternate embodiment, the IR heaters can also conduct heat into the trays. Using IR instead of water saves energy because it shortens warm-up time. Using IR also eliminates contaminated water and enables separate and individual temperature control of each tray. Tray temperature is maintained under computer control using contact or optical/IR temperature sensors.
