Leader Microwave Equipment Company’s twin-screw extruder is an important invention in food extruder industry. Can make the material fully mixed evenly, through the mouth mold molding . In those bulking methods, we recommend that you use a Leader twin screw extruder.

The twin-screw extruder is widely used in food processing and production. Our twin-screw extruders are becoming more and more popular among global investors due to their high efficiency, easy operation and high degree of automation.

Leader twin-screw extruder is equipped with industry-leading assembly technology and quality.The process of installation and debugging is strictly monitored by professionals, so that the equipment has the characteristics of stable operation, high output and low energy consumption.

Our products, including twin-screw puffing food snack equipment, corn puffing food machine, small snack puffing equipment and so on, are widely used and recommended in the Philippines, Indonesia, Canada, the United Kingdom, Romania, South Africa, Dominica, South Korea, Ukraine and other countries.

  Which characteristics make the Leader twin – screw extruder a necessary bulking equipment?

  • 1.Transmission case:The transmission box of twin-screw extruder extrusion equipment draws on the advanced design scheme of Germany, which is devoted to the gear transmission device with hard tooth designed by twin screw extruder for corn snacks.
  • 2.Box:Choose high quality thick wall casting, have the function of stable anti – shock and absorbing noise, using advanced production technology. After sufficient aging treatment, ensure the high accuracy and reliability of the case and long service life.
  • 3.Gear:High quality alloy steel, precision above grade 5, high hardness of tooth surface, and modification of tooth profile and helix .Gear fully meshes under load, ensuring stable and efficient transmission and low noise.
  • 4.Bearing:Use well-known brand, durable, smooth operation.
  • 5.Mechanical seals:The sealing element usually uses famous brand, the sealing effect is good.
  • 6.Safety coupling :Twin screw extruder for puffing snack food line.All equipped with torque limited safety coupling, when the overload of the machine and equipment safe release, fully protect the transmission box and screw, reduce maintenance time and reduce shutdown loss.After eliminating the fault, it can be easily reset.
  • 7.Electrical drive components and control elements:The electric driving components and control components of twin-screw food machinery are selected from well-known brands in the industry to ensure the stable operation of automatic control system for a long time.

The working principle of twin-screw extruder:

From the movement of the basic principle, the twin screw extruder, the same mesh and different mesh and non-mesh type is not the same.

1.Double screw extruder with same engagement

This kind of extruder has low speed and high speed 2 kinds.The low-speed extruder has a screw with tight mesh geometry, one of which has a screw edge shape that fits tightly with the other, that is, a conjugate screw shape.The high – speed coaxial extruder has a tightly matched spiral profile. When the clearance between such screws is set very small, the screw has a closed self-cleaning effect.This kind of twin – screw extruder is called compact self – cleaning rotary twin – screw extruder in the same direction.

2.Double screw extruder with different engagement

Double screw extruder with close engagement and different rotation’s gap that between the two screw slots is very small, thus can achieve the positive transmission characteristics.

3.Non – mesh twin – screw extruder

The center distance between the two screws of the non-mesh twin screw extruder exceeds the sum of the two screw radii.
