  • Patent number: 4568552
    Abstract: A method and a device for broiling food products such as hamburgers are disclosed wherein the food products are positioned between a lower heated broiling surface and an upper heated broiling surface for broiling the products by contacting corresponding sides thereof. The broiling surfaces are periodically displaced transversely relative to each other during the broiling of the food products so that the products are alternately in contact with both of the broiling surfaces and in contact substantially with only one of the broiling surfaces. The food products are intermittently displaced linearly relative to the broiling surfaces so that the food products are conveyed therebetween. The periodic displacement of the broiling surfaces transversely relative to each other and the intermittently displacement of the products linearly relative to the broiling surfaces are such that the food products are in contact substantially with only one of the broiling surfaces relative to which they are being linearly displaced.
