1. Hot Air System

This system provides clean air before drying.

• Filtration capacity: 8000m3/h (max)
• Pressure drop: 50Pa
• Material: filter material is non-woven fabric
• Heating system: direct-fired gas hot blast stove
• Heater material: inner tank 310S stainless steel

2. Drying System

Upper Bed Body: The upper bed separates the drying area from the atmosphere to prevent dust leakage from causing environmental pollution. The size of the upper part is larger than that of the lower part, so the wind speed of the upper part is lower than that of the lower part, which is conducive to particle sedimentation, reduces the amount of dust entrained, and reduces the amount of dust collected by the dust collector. The amount of dust, less dust is emitted to the atmosphere, and it is more environmentally friendly

Lower Bed Body: The lower bed is the air chamber into which the hot air enters, and the bed board completes the task of evenly sending the hot air into the bed. At the same time, the vibration motor is also installed on the lower bed. The volume of the lower bed is related to the uniformity of the pressure drop and the fluctuation of the pressure drop. For this reason, there must be a large enough volume and length of the lower bed, we can provide 30 vibrating fluid bed, 40 vibrating fluid bed, and 60 feet long vibrating fluid bed. The lower bed must bear the dynamic load of all the vibration bodies, so The lower bed should be designed as a box frame structure.

Bed Board: The main machine adopts the combined opening method of the serpentine hole and straight hole. The material contact adopts SUS316L stainless steel.

3. Dust Removal System

This system is composed of one set of SUS304 stainless steel primary cyclone separator, its diameter is XF-φ900.

4. Control System

Electrical control system configuration description:

• The inlet air temperature is automatically adjusted by PLC.
• The feeding amount can be automatically adjusted according to the change of the outlet air temperature.
• Real-time monitoring of the main parameters such as the pressure in the dryer, the temperature of the air inlet and outlet, and the differential pressure.
