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:

1. 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.

2. 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.

3. 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.

4. 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.
