  • Patent number: 8569662
    Abstract: A continuous oil fryer used to fry food slices, such as potato chips, having an internal oil stripping capability. The fryer accumulates the steam produced by the frying process in a hood and utilizes such steam, after superheating the steam by passing it through a heat exchanger, to strip oil from product immediately upon removal from the hot oil bath by passing the superheated steam through a product bed while on an output conveyor. The superheated steam removes oil from the product on the output conveyor without increasing the moisture level of the product. The fryer therefore accomplishes the same function as a low-oil stripper without increasing the footprint of the frying unit and with less energy.

  • Patent number: 8079302
    Abstract: Described here is a rectangular, parallelepiped shaped, portable cooking device that consists of a rigid Stand, with attached lid and flaps, that supports multiple food heating containers. A dual purpose transport case/cooking cover, made of heat resistant materials, is a key feature to the design utility by securely transporting the device and acting as a heat efficiency Cover during the food heating process. When used in conjunction with the Stand flaps and lids, this Cover provides many innovations over prior art by preventing heat escape and weather intrusion. Various burner and fuel devices (i.e.: Sterno, Propane, Electric, Coal, Wood . . . ) can be used to provide the heat for this device. The combination of these multi-functional components, in a single compact, portable, modular unit provide significant improvements over current conventional devices by offering multiple options for food heating and serving with increased efficiency in space usage, heat efficiency and transportability.

  • Patent number: 7791003
    Abstract: An insulated bag has generally flat top and bottom walls connected by foldable back and opposite side walls which cooperate to define a chamber having a front opening for receiving a food product. Flexible closure flaps extend from the bottom wall and opposite side walls and have releasable fasteners for closing the front opening. Each wall has an outer fabric covering and a porous inner liner and also inner and outer layers of flexible thermal insulation material. A vapor barrier film separates the inner and outer layers of insulation material in each wall and provides for moisture absorption by the inner layers. The top and bottom walls each have a compartment with an edge opening closed by a releasable fastener, and a vacuum insulation panel is confined within each compartment. The top and bottom walls move between a collapsed storage position and an expanded position to receive the product.

  • Publication number: 20100089902
    Abstract: The invention involves a temperature regulated heated Pizza/Food delivery system that ca provide a continuous warming solution for pizza and food from the store, to the car and to the customer, in a vehicle, including the ability to be battery-powered, should an electrical outlet not be available. This invention can use a dual powered technology to power the heater directly from 110/220V AC wall outlets or 12V DC automotive outlets without needing power adapters. The heater's power plug can be a magnetic breakaway connector, accessible through an opening in the insulated bag. Two colored LED indicators can be used to indicate the source of power. A set of detachable feet that fit into the keyhole slot of the heater can allow it to stand independently. The Nonstick, water-resistant heater surface can allow it to serve heated food directly, replacing the ubiquitous fire hazard, Sterno.

  • Patent number: RE45789
    Abstract: Apparatus for and methods of rethermalizing a package of refrigerated or frozen food are disclosed. In general, heating mechanisms are brought into conductive heat transfer contact with the package of food and operated for a duration of rethermalization time to rethermalize the package of food by heating the food to a rethermalized temperature, and then, if desired, to hold the rethermalized package of food at a desired holding temperature for a duration of holding time. The rethermalization time can be relatively short (e.g., thirty minutes or less), and the holding time can range from a very short period of time to a very long period of time (e.g., four, six, eight or more hours) without significant loss of food quality. Other features of the apparatus and methods are disclosed.
