About 78 Model Twin Screw Extruder

Structure detaili14

The main extruder adopts frequency speed controlling withm high automation and stableper-formation.
The screw is made of alloy by Nitriding process, high strength and wear-resisting. And ithas good self-cleaning ability and doesn't need to discharge or clean the barrel and screw, when restarting orreplacing of materials.
Brrel with water-cooled circulation, it makes extruder can be used not only fro corn/rice,also for wheat flour/starch which are raw materials with high viscosity.Through different moistrue-extrusion temperature ratio. it can make whole-expanded and half-expanded as different types of products. elf-cleaning, when stopping, it can be cleaned without disassembling

Functioni14Double Screw Extruder serves to gelatinize flours andstarches continuously and automatically. After dosing, the materials are worked by two co-rotating screws composed by sectional modules for the following
