How Does A Food Extruder Work. The barrel is a heated hollow steel cylinder sort of like a really thick pipe. In the extruder under the high-temperature heating powder and granular materials are quickly melted.
An auger-type screw rotates inside of the barrel. Its main principle of operation is the screw in the high-speed rotation of the feeder mixture to the head part. Twin screw extruders consist of two intermeshing co-rotating.
Extrusion processing aims to physico-chemically transform continuously viscous polymeric media and produce high quality structured products thanks to the accurate control of processing conditions.
Its main principle of operation is the screw in the high-speed rotation of the feeder mixture to the head part. We should probably start with what an extruder is. The first basic component of the extruder is a delivery system. First raw material in the form of small plastic pellets is placed in the hopper.
