Patents Assigned to The Delfield Company
  • Publication number: 20240225358
    Abstract: A food serving station which includes a thermally conductive collar with a thermal break to minimize heat transfer between the side walls of a food well and a metal work top, such that the thermal break minimizes unwanted heat transfer between those two parts and allows more effective and efficient heat transfer from the food wells to the food in the food pans. This heat transfer allows the level of the food in the food pans to be raised to the level of the work top while still maintaining compliance with the NSF temperature requirements and reducing energy use.

  • Patent number: 8727186
    Abstract: A product delivery mechanism for a beverage dispensing system that dispenses flavor/ingredients and ice into a serving cup for mixing and/or blending. The product delivery system includes a gas operated pump for moving the flavor/ingredients from a product source to a dispensing nozzle above the serving cup. A gas restrictor is connected to an exhaust port of the pump to regulate gas flow rate and product flow rate so as to prevent splashing at the cup while operating the pump well within its rated pressure limits.

  • Patent number: 7069732
    Abstract: A temperature control system for maintaining a food product at an acceptable temperature having a pan with a thermally conductive wall, a first member surrounding the thermally conductive wall, and a channel being formed between the first member and the thermally conductive wall. The temperature control system has a fluid in the channel for contacting the pan at a first location and a refrigeration coil being connected to a portion of the thermally conductive wall for cooling the pan. The temperature control system further has a second member for surrounding a first portion of the thermally conductive wall. The second member and the fluid maximize heat transfer at a first portion of the thermally conductive wall. The second member minimizes heat transfer at a second location of the thermally conductive wall.

  • Patent number: 6467294
    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.
