200kg/H Closed Cycle Centrifugal Spray Drying Equipment For Powder Collection

Descriptions

A closed-cycle spray dryer is a specialized type of spray dryer that operates in a sealed, closed-loop system. It is designed for applications involving sensitive, hazardous, or flammable materials. Unlike open-cycle spray dryers, which release exhaust gases into the environment, closed-cycle spray dryers recycle the drying medium (such as nitrogen or air) within the system. This makes them safer, more energy-efficient, and environmentally friendly.

Example Process Flow Diagram (Textual Description):

1. Step 1: Feed liquid is atomized into fine droplets in the drying chamber.
2. Step 2: Heated inert gas (e.g., nitrogen) enters the chamber to evaporate the solvent.
3. Step 3: Dried powder is separated from the gas stream using a cyclone separator.
4. Step 4: Solvent vapor is condensed and collected in the condenser.
5. Step 5: The inert gas is filtered, reheated, and recirculated into the drying chamber.

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.
