Food extruder SX3000 series

The introduction of Single Screw Extruder: Single-screw extruders use one single screw in the barrel of the extruder to transport and shape multiple ingredients into a uniformfood product by forcing the ingredient mix through a shaped die to produce the uniform shape. Single-screw extruders typically consistof three zones: feeding zone, kneading zone, cooling zone. In contrast to twin-screw extruders, single-screw extruders have poormixing ability and therefore materials should be pre-mixed or pre-conditioned. A single-screw extruder’s processing conditions can be controlled to achieve a variety of effects on temperature and residence time. The residence time in the barrel can vary from 15 to 300 seconds, determined by increasing or decreasing the speed of the shaft. A variety of fried and baked snacks are processed using single-screw extruders.
