Abstract

An apparatus for forming longitudinally extending bores in food products includes a hollow circular coring knife having a cutting edge formed at a terminal end thereof. Another end of the knife is connected to a connection member rotatively carried by a bearing and which has a passageway formed along the length thereof in communication with the hollow portion of the circular knife. The connection member is rotatively driven by drive means and sealingly connected, at the passageway, to a vacuum source. A retainer structure carries two types of food products, one a relatively larger product in which a larger bore is formed by a knife. The retainer structure is slidable with respect to the knife so that the knife is inserted a predetermined extent of the length of the food product, normally a bun. A second food product, normally a wiener, is also placeable within the retainer structure and bored but at a smaller diameter. The bun bore receives the wiener therealong and the wiener bore or the bun bore receives condiments or other filling to make a final food product.
