  • Patent number: 4700619
    Abstract: An improved removable cooking surface assembly for the upper movable heated platen of a two-sided cooking device is disclosed. The assembly includes a planar rigid heat conducting metal plate which is coated on its lower surface with a layer of non-stick synthetic plastic material. The coated platen is removably connected with the heated platen and extends in contiguous relation across the lower surface thereof for uniform heat transfer from the platen to the food product being cooked. Following cooking of the product when upper platen is raised, the food product remains on the lower grill surface since the coating of the upper surface prevents the product from sticking thereto. After extended use, the cooking surface assembly is easily removed from the upper movable platen for refurbishing or replacement.

  • Patent number: 4241650
    Abstract: An apparatus for cooking or otherwise heating food held in a container which includes upper and lower housing portions. Heating elements are located in the respective housing portions, and the opposed inner walls of the housing portions are adapted to be moved into contact with the food container. The heating elements are positioned immediately adjacent these walls, and these elements are substantially insulated from other portions of the housing. The intimate contact between the inner walls and the associated heating elements causes the food to act as a heat sink whereby the food is rapidly heated in a highly effective manner. The apparatus is particularly useful for the cooking of frozen food located in an appropriate container. Means are provided for retaining the upper housing in spaced apart relationship with the lower housing to permit baking and similar heating.
