Experimental Twin-Screw Extruder
The experimental twin-screw extruder is specifically designed for universities, research institutions, and large and medium-sized enterprises, serving as a multifunctional extrusion experimental platform. The machine features a segmented barrel and an integral screw with a length-to-diameter ratio of 23:1, a stepless adjustable speed range of 0-500 rpm, and a controllable temperature range from room temperature to 300°C (accuracy ±1°C). The die pressure is monitored in real time from 0-30 MPa, simulating industrial production conditions. The main motor, feeder, and rotary cutter all adopt variable frequency speed control, with centralized control for easy operation.
The structure of the equipment is highly similar to that of an industrial extruder, making the experimental data more valuable for engineering reference. The screw configuration is flexible and adjustable, suitable for various materials such as grains, tubers, starches, and chemical raw materials. It is powerful, highly simulatable, easy to maintain, and low in cost, making it an ideal experimental platform for teaching research and process development.
The experimental twin-screw extruder is a multifunctional extruder developed by the company for universities, research institutions, and large and medium-sized enterprises and institutions to conduct various extrusion puffing, cooking, modification, etc., research and development to meet different process requirements. During operation, parameters such as temperature, pressure, and rotational speed are displayed. By selecting different screw configurations and length-to-diameter ratios, it can meet various experiments on grains, tubers, starch, chemical raw materials, and other materials, providing a multifunctional experimental platform for teaching and research.
