The teaching experiment puffing machine produced by Jinan Saixin Machinery Co., Ltd. is a small multifunctional puffing machine which can meet the requirements of different processes based on the characteristics of single and twin screw extrusion puffing principles. It can accurately and quickly adjust and feedback parameters such as moisture, pressure, temperature, and speed during the extrusion process, and display it digitally. The experimental extruder adopts a segmented combined screw structure, and uses different screw combinations and length-to-diameter ratios, which solves the problem of combining theory with practice in teaching and scientific research and completely changes the current situation of relying on operating experience control. With the continuous development of Saixin Machinery Company, the experimental puffing machine has also been updated and sold to universities and research institutions all over the country, and the feedback information is good.

Advantage of Double-screw testing extruders:

1 Patented design, multifunctional small test twin screw extruder has been upgraded and revised many times.

2 Using Φ32mm screw, according to different raw materials and product properties, multiple screw / barrel combinations with different lengths can be used to complete a variety of extrusion experiments.

3 Dedicated gear boxes and bearings.

4 Multi-point temperature control and pressure measurement points.

5 Advanced friendly touch human-machine interface, HMI and random help system, temperature and motor are controlled by high-performance PLC, which can display a large number of real-time parameters, record the working status of each unit device, and print out.
