A food container includes an interior chamber sized to contain food items, the interior chamber having a first temperature zone and a second temperature zone. The food container further includes an opening providing access to the interior chamber, a fan configured to supply an air stream to a duct system, and a heater configured to heat the air stream, where the duct system is configured to deliver a portion of the air stream across the opening, creating an air curtain. The food container further includes a diverter disposed in the air curtain to divert a portion of the air stream out of the air curtain and into the interior chamber, the diverter configured to cause the second temperature zone to maintain a second temperature different from the first temperature. The food container further includes a temperature control system having a user interface, an input configured to receive a signal from the user interface, the signal representative of a first temperature, and a processing circuit configured to control the heater to bring the first temperature zone to the first temperature.
