  • Publication number: 20140326003
    Abstract: The food storage device of the present disclosure includes a cover that can be connected to a food pan, and which at least partially separates refrigerant coils from surrounding insulating foam. This helps to prevent corrosion of the coils caused by condensation reacting with insulating foam, and also helps to prevent the coils from separating from the pan.

  • Patent number: 8863992
    Abstract: An ice portion control module is provided that includes an ice bin for storing ice having a base in the ice bin having one or more portion control compartments and one or more magnets associated with the one or more portion control compartments, the one or more portion control compartments having an interior volume to hold a predetermined portion of the ice, an actuator which moves the one or more portion control compartments between a fill position wherein the one or more portion control compartments holds the ice, and a dispense position wherein the predetermined portion of the ice is dispensed out of the one or more portion control compartments, and a sensor outside of the ice bin that detects the one or more magnets.

  • Patent number: 7748228
    Abstract: A storage system that has variable temperature includes one or more drawers. The one or more drawers are independently operable of one another. A heating and cooling system is in thermal communication with the one or more drawers. The heating and cooling system generates even air-flow around all sides of the one or more drawers for heating and/or cooling thereof.

  • Patent number: 6616011
    Abstract: Liquid dispensing equipment that includes a dispensing head that maintains a liquid or beverage line and delivery tip at a cool temperature so as to avoid contamination of the beverage. The liquid dispensing equipment also includes a storage refrigerator that cools a container of the beverage. A fan assembly is disposed to develop a cool airflow that flows through the storage refrigerator and a passage of the dispensing head. The liquid line and a delivery tip are disposed in the passage. A baffle arrangement maintains a volume of the cool airflow in a chamber adjacent the delivery tip so as to provide a shield against warmer ambient temperatures.

  • Publication number: 20020162347
    Abstract: A self-service food display in which a food tray that is supported by a support structure is cooled by an air stream that passes over and under the tray. The tray has opposed end sections and one or more intermediate sections. The air stream is uniformly distributed over the intermediate sections to substantially maintain the same temperature in the vicinity thereof. The air stream is distributed to the opposed end sections in higher volumes to minimize heat transfer with ambient. The air stream also forms an air curtain that extends above three sides of the food tray. Additionally, the air stream is distributed at an angle to an upper surface of the food tray in a manner that provides higher volumes to the opposed end sections to minimize heat transfer.
