5kg/H Closed Cycle Centrifugal Spray Dryer With A Inlet Gas Nitrogen
Descriptions
A Closed-Cycle Centrifugal Spray Dryer is a specialized spray dryer that operates in a closed-loop system and uses a centrifugal atomizer to disperse liquid feed into fine droplets for drying. The system is particularly suited for materials that are flammable, heat-sensitive, or involve organic solvents, as it operates with an inert gas (e.g., nitrogen) in a controlled environment. This setup ensures product safety, high-quality output, and efficient solvent recovery.
How It Works:
-
Liquid Feed Atomization:
The liquid feed is introduced into the drying chamber through a high-speed centrifugal atomizer. The atomizer spins at high speeds (10,000–50,000 RPM), breaking the liquid into fine droplets. -
Drying in a Closed Loop:
The droplets are exposed to a heated inert gas (e.g., nitrogen) in the drying chamber. Solvent evaporates quickly due to the high surface area of the droplets. -
Inert Gas and Solvent Recovery:
The inert gas carrying the evaporated solvent exits the chamber and passes through a condenser. The solvent is condensed and collected for reuse, while the inert gas is reheated and recirculated. -
Powder Collection:
The dried particles are separated from the gas stream using cyclones, bag filters, or electrostatic precipitators. The final powder is collected in a container or hopper.
Advantages of Closed-Cycle Centrifugal Spray Dryers:
- High Product Quality: Produces uniform, high-purity powders with controlled particle sizes.
- Safety: Inert gas environment prevents oxidation, combustion, or contamination.
- Solvent Recovery: Captures and recycles expensive or hazardous solvents.
- Environmental Compliance: Reduces emissions and waste, meeting strict environmental regulations.
- Energy Efficiency: Reuse of inert gas and heat recovery systems reduces energy consumption.
Centrifugal spray atomizer Features
1. High speed drying. The surface area of Raw Material liquid increased a lot after atomization through nebulizer, 95%-98% of moisture will be evaporated in high temperature airflow in a flash, only needs seconds time.
2. Adopts Single position spray drying to make the liquid drop and hot air running in same position. Although the temperature of the air is high, the hot air contacts Liquid Drop once come into drying tank. So the temperature decreased at once to protect the material out of over heated. This is machine is also fit for the materials which are sensitive with Heating.
