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.

Abstract: An apparatus for placing a grill stripe or score mark on a meat product by transporting the meat product against a heated grill. A continuous conveyor transports individual wieners along a path of conveyance. A belt conveyor raises the wieners above the supported path of the continuous conveyor and into rotational contact with the superimposed heated grill. The wieners are rotated one complete revolution against the grill while synchronously moving the wiener with the continuous conveyor. The wieners are returned to the continuous conveyor for further processing.
