ABSTRACT:
In a cracker production apparatus of the type comprising a heatable mould consisting of a stationary upper mould element, a movable ring mould and a reciprocating lower mould element or punch driven by a hydraulically actuated toggle-mechanism, the improvement wherein a twin-head mould arrangement for high rate, automatic manufacture of uniformly expanded crackers is driven by a single hydraulic drive unit formed of two aligned, cooperating double-action pistons, whereby a first piston is adapted to control, in combination with specific central program/microprocessing means, an adjustable final baking pressure, and a second piston to regulate a desired expanded cracker thickness, and this independant of grain feed and/or apparatus related mechanical parameters. Advantageously two twin-head machines are arranged in tandem with a single hydraulic drive unit and mutually connected toggle members whereby a cracker conveyor belt passes between the cracker discharge chutes of said tandem arrangement of twin-head machines. The ring moulds may be designed for allowing multiple cracker production in each mould set.
