Title: Piston feeder for supply of dough - giving portions of consistant weight and volume
Inventor: SCHROEDER HERBERT
IPC: A21C5/04
Filed: 1974-12-31
Abstract: A continuously operating machine for delivering portions of dough consistently of the same weight and volume, and for pref. also for the subsequent treatment of the dough; has a dough hopper and a feeder, progressing the dough piece by piece into a closed antechamber. A piston moving in the chamber transfers the dough pieces into metering chambers moving across an outlet connecting with chamber, and is arranged so that a shortage of dough in front of the piston, switches on the feeder, which then runs for a predetermined time, or feeds in a definite quantity of dough, and is then switched off. After a metering chamber has been filled, a limit switch energises the feeder, as soon as there is less dough in the chamber than will fill a metering chamber. Between main shaft and the feed piston there is a spring coupling having only a slight variation in loading over a long motion, and comprising a rotary spring working between two dish springs. These transmit a flexible drive to the plunger. There is no uneven crushing of the mass of dough with consequent damage to the fermentation cells. A feeler for the quantity is avoided, making cleaning easier.
