Title: Automatic dough portioner ensuring accuracy and gentle handling - sucks and presses dough into revolving chambers simultaneously
IPC: A21C5/04
Filed: 1976-05-29
Abstract: A dough portioning machine for dispensing pieces of dough of consistently uniform weight, applicable in both small and large bakeries, has a feeding device above the frame holding a revolving drum. The drum cuts across the face of the nozzle from which the dough is extruded and has four to six rows of measuring chambers with two to six chambers in each row. There is a piston in each measuring chamber with a roller following a cam track fixed on a hub on a hollow shaft on which the drum rotates. Above the hollow shaft a section of each cam track is cut away and a movable section is attached by tie rods to a horizontal shaft inside the hollow shaft. The piston in each chamber can thus be drawn downwards to assist the filling with dough and then returned for the roller to follow the fixed cam track as the drum rorates. Additional tie rods at the ends of the inner shaft operate the dough feeding mechanism, so that the ejection of the dough and the drawing down of the pistons takes place simultaneously. Machine runs at relatively high speed giving consistently accurate weight handling the dough portions carefully.
