Spray dryer introduction

1. Industrial Drying Equipment: The spray dryer is a piece of industrial drying equipment used to convert liquid feed materials into dried powder or granules.
2. Atomization and Drying: The liquid feed material is atomized into small droplets and quickly dried by hot air or gas, resulting in a dried product.
3. Widely Used: Spray dryers are widely used in industries such as food and beverage, pharmaceuticals, chemicals, and more, due to their versatility and efficiency.
4. High Efficiency: Spray dryers can achieve high drying efficiency and can handle a wide range of materials.
5. Compact Design: The compact design of spray dryers makes them suitable for both laboratory and industrial-scale applications.
6. Customizable: Spray dryers can be customized to meet specific process requirements, such as moisture content, particle size, and more, ensuring optimal drying results.

The working principle is as follows

1. Atomization: The liquid feed material is atomized into small droplets using a high-pressure nozzle or rotary atomizer.
2. Drying Chamber: The atomized droplets are introduced into a drying chamber filled with hot air or gas.
3. Rapid Drying: As the droplets fall through the chamber, they are rapidly dried by contacting the hot air or gas.
4. Dried Particles: The dried particles are then collected at the bottom of the drying chamber.
5. Moisture Removal: The hot air or gas evaporates the moisture from the droplets, leaving behind dried particles.
6. Particle Collection: The dried particles are collected using a cyclone separator, bag filter, or other collection method.
