A sandwich bin for fast food restaurant service. The sandwich bin provides always open front and rear service openings and air curtains for each of the service openings. The air in the air curtains is recycled through chambers at the sides of the sandwich bin to beneath the floor from where it is recirculated through ducts and over heaters to be discharged through air curtain forming nozzles. The turbulence in the sandwich bin is at a minimum, thereby providing an atmosphere in which sandwiches will remain hot and moist, without significant drying. |
