Process Description
This process consists of a filter cake preparation system, filter cake conveying system, hot air supply system, drying system, and exhaust gas treatment system.
The filter cake preparation system uses a filter press to transform slurry with ~70% moisture content into filter cake material with ~35% moisture content.
The filter cake material is then fed into the drying equipment via belt conveyors and screw conveyors.
The hot air supply system comprises:
- A burner for fuel combustion
- A high-temperature gas purification unit to ensure clean drying flue gas
- An air mixing device to maintain the drying air temperature within process requirements
Technical Advantages
- Complete combustion with smoke-free hot air
- High air purity: Dust content ~30mg/Nm³ (purification process can be customized)
- Precise temperature control: Adjustable between 300–400°C (±3°C stability)
- Durable equipment with low operating costs
- Combustion thermal efficiency >97%, about 20% improvement over traditional heat exchange systems, significantly reducing energy consumption
- High product purity and whiteness

Direct Oil/Gas Fired Hot Air Furnace
Direct Oil/Gas Fired Hot Air Furnace is mainly composed of the burner, furnace body and control system. The burner adopts imported integrated burner. Fuel and air enter the furnace body at a certain ratio and burn completely inside. Ambient air passes through the furnace jacket and mixes with high-temperature flue gas to obtain clean flue gas at required process temperature. Single unit heat supply capacity: 50-200x10<sup>4</sup> Kcal/h. Heat supply temperature ≤1000°C.
Spray drying is one of the most widely used processes in liquid forming and drying process. It is suitable for producing powdered or granular solid products from raw materials such as solutions, emulsions, suspensions, and pastes.
