What are the drying equipment for indirect drying
  In today's market, the work of drying equipment is divided into indirect drying and direct drying. At the same time, indirect drying equipment can dry products including pharmaceuticals, photochemicals, agrochemicals or explosives, and can also dry special chemicals with sensitive characteristics.

  Paddle type drying equipment can operate in a horizontal plane, and the machine has a cylindrical container with multi-paddle agitators at both ends. In most designs, the heating fluid circulating through the vessel wall also flows through the agitator. The combination of the movement of the stirrer and the heating element makes the machine very suitable for efficient mixing and heat transfer. In addition, the support structure of the agitator allows processing of high shear or lumpy solids, and the product is discharged through the outlet at the bottom of the cylindrical housing.

  A disc drying equipment that is widely used and can be dried in batches. This machine can handle various solids, including wet cakes or slurries. The device consists of a container shell surrounding a rotor mounted vertically or horizontally, a series of discs placed at an angle and connected to the tubular rotor. The heating fluid not only flows through the container wall, but also flows through the rotor and the disk, thereby forming a high heat transfer area.
