摘要:
A banquet cart includes a heater received in an opening in the bottom panel of the banquet cart. Plates of food are loaded into the interior compartment of the banquet cart in the kitchen. The heater includes a central heater unit and two heat retention material heating panels. The central heater unit heats the interior compartment of the banquet cart for twenty minutes. The central heater unit is turned off, and smaller heaters are turned on to heat the heat retention material heating panels for forty minutes. The smaller heaters are turned off and the banquet cart is rolled from the kitchen to a hallway proximate to the dining area for serving the plates of food to guests. The heated heat retention material heating panels can maintain the temperature of the air in the interior compartment of the banquet cart warm for approximately two hours and forty minutes, keeping the food in the banquet cart warm.
