EXT30/32 Extrusion Testing Machine
EXT30/32 Extrusion Testing Machine

1. Instruction

Our companys lab twin-screw extruder is researched and developed for universities and colleges, scientific research institution and large and medium food enterprise. It is a multifunction extruder to perform experiments of extrusion, ripen and degeneration. In working process, the temperature, pressure and rotating speed can be displayed on the screen. By adopting different screws combination and length-diameter ratio, our lab twin-screw extruder is fitting for different experiments with different raw materials, such as cereal, potato, starch and chemical materials. It is a good experimental platform for teaching and research.
