Abstract
This apparatus provides positive displacement synchronized metering of pressurized food material to a plurality of dies using several positive displacement metering apparatus. The metering is provided by the energy of pressurized material itself, or, for more viscous material, it can be supplemented by a motor. Supplemental material can also be introduced along with the food material to modify the characteristics of the food material.
Claims18
Apparatus for metering pressurized, viscous food material comprising:
- a plurality of positive displacement metering means having input means for receiving material to be metered and output means for discharging metered material, said metering means being operated with energy obtained from said pressurized material;
- and
- means interconnecting a predetermined number of said metering means for synchronizing the interconnected ones of said metering means.
