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.
Claims22
Apparatus for extruding pressurized material comprising:
- a) a plurality of first positive displacement metering means for metering extrudable pressurized material, said metering means having an input duct for receiving material and an output duct for discharging material, said metering means also having interconnecting means for synchronizing said plurality of first metering means, said first metering means operating energy being obtained from said pressurized material;
- b) delivery means for delivering extrudable pressurized material to each said first metering means input duct;
- c) a plurality of die means for receiving material from each said first metering means output duct and extruding said material.
A process for extruding multiple streams of food materials comprising:
- a) providing apparatus comprising:
- 1) a plurality of first positive displacement metering means for metering extrudable pressurized material, said metering means having an input duct for receiving material and an output duct for discharging material, said metering means also having interconnecting means for synchronizing said plurality of first metering means, said first metering means operating energy being obtained from said pressurized material;
- 2) delivery means for delivering extrudable pressurized material to each said metering means input duct;
- 3) a plurality of die means for receiving material from each said metering means output duct and extruding said material;
- b) metering a pressurized extrudable food material from said delivery means to said die means using said first positive displacement metering means;
- and
- c) extruding said food material through said die means to form multiple streams of food materials.
