Mixing and drying machine production line

Principle of different styles of mixing and drying machines

1. Cylindrical mixing blade dryer. In a horizontally installed cylinder with a jacket, a rotating shaft is set along the center of the equipment, which is equipped with many mixing blades. The two ends of the shaft are supported by bearings on both sides of the cylinder. The heating surface is a cylindrical jacket, and different heat carriers are located inside the central rotating axis. At the material outlet, the retention time of the material in the drum can be adjusted by changing the direction and angle of the stirring blade.

2. Spiral stirring blade dryer is a type of dryer that is based on a horizontal screw conveyor, with a jacket added to the cylinder and a heat carrier installed inside. The material achieves the purpose of heating and drying while being transported by the auger. Spiral conveyors can be single axis or double axis.

The above two categoriesMixing and drying machine manufacturerDue to the fact that the stirring blades of the dryer do not input heat carriers, the heating surface only comes from the jacket of the drying chamber shell. The drying of the material is achieved by the centrifugal force generated by the rotation of the high-speed stirring blades, which disperses the wet material to the jacket on the inner surface of the container and repeatedly contacts the heating surface to dry the material. Therefore, the linear velocity of the stirring blades in this type of dryer is 5-15m/s, the heat transfer coefficient is 116+456W/degree multiplied by the square of m, and the material residence time is about 2-10 minutes.
