Abstract
A self-regulating warmer device which is especially suited for the food service industry. Such devices are suitable, for example, for keeping wrapped or unwrapped food products at a desired holding temperature between the time the food is prepared and the time it is delivered to the customer. The warmer device includes a plate on which the food is held and a self-regulating warmer element beneath the plate to keep the plate at a uniform temperature. The plate is preferably used with spaced apart infra-red convection heaters such as those commonly used in fast food restaurants, and provides even food heating regardless of the changes in ambient conditions, the number of food products located between the infrared heater and the plate and provides dramatic reductions in power usage. Moreover, heat losses which occur at the edges of the plates now used for these applications are reduced and localized hot or cold spots are eliminated. Foor products can then be held at the mandated temperature levels required for safety considerations.
