1. An apparatus, comprising:
a removable food container tray configured to hold food items;
an integrated heat tray insert coupled to electrical components and configured for warming the food items placed in the removable food container tray, wherein the removable food container tray is further configured to be detached from the integrated heat tray insert to allow the food items to be served independently of a food warming device and to enable cleaning of the removable food container tray separate from the food warming device;
a food warming device base unit coupled to the food warming device and configured to be powered with a removable battery through an electrical connection to generate heat in a plurality of heat-dispersing elements;
wherein the integrated heat tray insert is coated with a non-stick surface;
wherein the plurality of heat-dispersing elements are coupled to the integrated heat tray insert and configured to generate heat in the integrated heat tray insert;
a control printed circuit board assembly coupled to the plurality of heat-dispersing elements and including digital devices configured for activating and controlling the integrated heat tray insert through the electrical components including the plurality of heat dispersing elements;
wherein the control printed circuit board assembly is configured to include at least one digital processor, at least one digital memory device, at least one database, at least one infrared thermometer coupled to the control printed circuit board assembly, at least one chemical vapor sensing device, at least one circuit coupled to a removable food container tray cover, at least one first circuit coupled to at least one digital temperature display, at least one second circuit coupled to an alert light coupled to the removable food container tray cover, and at least one third circuit coupled to a temperature control selection device mounted on a heat tray insert mounting ledge;
a temperature control device coupled to the control printed circuit board assembly configured to regulate heat temperatures generated from the plurality of heat-dispersing elements;
at least one removable rechargeable battery pack of the removable battery and located on a base located adjacent to an external side of the integrated heat tray insert and coupled to the control printed circuit board assembly configured to have high current and heat resistant capability, wherein the at least one removable rechargeable battery pack is configured to allow a user to quickly release and remove the at least one removable rechargeable battery pack from the base;
wherein the at least one removable rechargeable battery pack further includes an external charging port configured to charge the at least one removable rechargeable battery when the at least one removable rechargeable battery is removed from the removable food container tray by the user; and
wherein the at least one removable rechargeable battery pack is further configured to supply direct current power to the electrical components for powering the plurality of heat-dispersing elements to heat levels above 140° F.
