Abstract
A piston depositor for depositing batter and the like into pans in an automated bakery line includes a valve housing which defines an inlet, a valve chamber, an outlet and a cylinder bore which intersects the valve chamber. A rotary valve is disposed within the valve chamber. The rotary valve selectively interconnects the bore with the valve housing inlet and the valve housing outlet. A piston and rod assembly is slideably disposed within the bore. A programmable drive system including servomotors controls the operation of the rotary valve and piston and rod assembly to intake batter through the housing inlet and discharge the batter through the valve housing outlet.
