Twin screw extruder

Twin Screw Extruder

Density Control System

There are two optional density controllers, pressurized and vacuum type, which are mainly used in the production of high bulk density extruded materials (such as sinking aquatic feed, nutritional rice, etc.), which can effectively increase the bulk density of materials, or increase the production capacity of the extruder, and Improve the appearance of materials;

Fully Automatic Control System

The fully automatic control system simplifies operations and reduces manual labor intensity;
All data are recorded, which reduces the impact of operators on the quality of puffed products to a relatively low level;
International brand control components ensure that the control system is stable, precise and sensitive;
It can be configured with two density control systems, vacuuming and pressurization, and cooperates with the fully automatic control system to ensure the stability of the equipment and improve the quality of puffed products.

Performance Features

High production capacity and low energy consumption. The new MFPH series twin-screw extruder adopts a 20:1 aspect ratio and a stabilized screw combination technology. It can give full play to the production capacity of both floating and sinking aquatic feeds, and the power consumption per ton is as low as 23~25kW.h/t;
Wide processing range and low production cost. The MFPH series twin-screw extruder has effectively and successfully solved the problems of poor stability in water, particle uniformity, and insufficient aesthetics encountered in the production of low-starch formulas, improved the feeding and digestion utilization rate of aquatic animals, and improved the growth performance and quality of aquatic animals;
Particle uniformity. It adopts full kneading screw technology, stabilized screw configuration, high-precision screw and inner sleeve, and double-die discharging device to optimize the pressure distribution before the die and ensure uniform particles;
The extruded particles have good ripening effect. Equipped with an efficient three-axis conditioner, its unique water-vapor co-advancing structure ensures that the water vapor and the material are fully mixed. The function of the conditioner is divided by software simulation technology, the blade arrangement is optimized, the material filling degree is improved, the effective conditioning time is extended, and the conditioning effect is improved;
Smooth operation, safe and reliable, and low failure rate. It adopts the world’s advanced symmetrical parallel five-axis gearbox, 6-level high-precision gears, and is equipped with imported brand bearings and oil seals. The transmission is efficient and the operation is stable and reliable. The new full-wear-resistant alloy screw has a screw life of more than 50,000t.

FAQ

What kind of fish feed can be produced by twin-screw extruder? How to choose?

Twin-screw extruder has the characteristics of wide adaptability, stable operation, simple and easy operation. It can produce high-starch and low-starch content feed, and can also produce slow-sinking and fast-sinking fish feed with density controller; our company's twin-screw extruder has different models with output of 0.2-20T/H, and customers can choose according to their needs.

What is the difference between a twin-screw extruder and a single-screw extruder?

Single-screw extruders have low costs, but their output and adaptability are not as good as those of twin-screw extruders, and they are difficult to operate. The production of fish feeds with different formulas requires high technical requirements for operators; twin-screw extruders are easy to operate and have strong adaptability. They can produce a variety of feeds with different formulas, and they have self-cleaning functions. There is also less waste generated by starting and stopping the machine, so most feed manufacturers are currently starting to choose twin-screw extruders.

What are the wearing parts of twin-screw extruders? Is the cost of use high?

The main accessories of twin screws are spirals, extrusion chamber sleeves, cutter blades, etc. The spiral is made of high-hardness wear-resistant alloy material, and its life can reach more than 5,000 hours. The spiral is equipped with a hydraulic ejector device, which is easy to replace; the sleeve life can reach more than 20,000 hours, and the sleeve adopts an embedded structure for easy replacement.
