Industrial Atomizers: Efficient Liquid-to-Particle Conversion for Drying

1. Rotary (Disk) Atomizer

Product Description

A rotary atomizer uses a high-speed spinning disk (10,000–21,000 RPM) to convert liquids like milk concentrate into fine droplets. Ideal for uniform spray drying processes.

How It Works

• Liquid feed is ejected from the center of a grooved or vaned disk.

• Centrifugal force spreads the liquid into a thin film, forming microdroplets.

• Fine droplets enhance evaporation and drying efficiency.

Applications

• Food Industry: Milk powder, instant coffee, and fruit concentrates.

• Pharmaceuticals: Controlled-size drug granules.

• Chemicals: Production of dye powders.

Key Benefits

• ✅ Uniform droplets with narrow particle size distribution.

• ✅ Handles viscous materials (up to 20,000 cP).

• ✅ Corrosion-resistant stainless steel or tungsten carbide disks.

2. Nozzle (Pressure) Atomizer

Product Description

A nozzle atomizer employs a high-pressure piston pump (up to 300 bar) to force liquid through specialized nozzles, creating micron-sized droplets. Perfect for heat-sensitive materials.

How It Works

• Liquid is pressurized through hydraulic or pneumatic nozzles.

• Nozzle geometry (cone, flat) breaks the liquid into fine particles.

• Droplets contact hot air in the drying chamber for rapid dehydration.

Applications

• Dairy: Protein powders and infant formula.

• Ceramics: Spraying ceramic slurries.

• Textiles: Nanofiber production from polymer solutions.

Key Benefits

• ✅ Precise particle size control (10–200 microns).

• ✅ Gentle on shear-sensitive materials (e.g., proteins).

• ✅ Easy nozzle replacement and maintenance.
