Machine for encapsulating food in dough

Abstract

Abstract A machine for extruding dough, typically of the bagel variety, about a food, such as a frankfurter, is disclosed. Typically, the frankfurters are loaded into a magazine. The magazine feeds a star wheel at the bottom. The star wheel singulates, rotates and discharges the frankfurters into a chute. Once the frankfurters are deposited in the chute, an endless chain with propelling pawls propels each sequential frankfurter through the chute concentrically to an extruder. The extruder continuously dispenses bagel dough concentrically around the frankfurters and is supplied with bagel dough under pressure by an auger flight extruder or other propelling mechanism. Extrusion occurs from an extrusion head having a frankfurter passageway centrally thereof. Dough is extruded into first and second extrusion chambers and out first and second immediately concentric extrusion annuluses about the frankfurter passageway. The dough encased frankfurter passes from the chamber onto a conveyor belt and under a sensing roller and a downstream knife. The sensing roller is separated from the knife by the spatial interval equal to about the length of a dough encased frankfurter. By sensing the interruption in the dough marked by the absence of a frankfurter, actuation of the knife occurs, severing sequential bagel dog products one from another so that discharge of the complete and severed dough encased frankfurter at the end of the line occurs.
