Dough forming apparatus

摘要

A horizontal chamber and a piston movable in the chamber to discharge potato dough through a discharge opening at one end of the chamber. A dough dividing structure adapted for mounting in the discharge opening. A diaphragm and means for mounting the diaphragm on the face of the piston such that when the piston is retracted in the chamber from a body of dough therein, an air passage is created to relieve the vacuum between the diaphragm and the dough, thereby avoiding distortion of the dough. For charging the chamber with a body of dough to form an impervious barrier therein there is an adapter in vertical alignment below the constitutent introducing devices; the adapter supports the piston and the cylinder in vertical alignment below the constituent introducing devices so as to expedite charging of the machine to form an impervious dough barrier. After the constituents set into a dough the chamber, with the impervious barrier therein, and the piston are installed in the machine for normal operation. An improved nozzle for introducing the water constituent which nozzle virtually eliminates all kinetic energy or velocity necessarily developed when the water is delivered to the nozzle.
