Types of spray dryers

Compressed air spray dryer: uses compressed air to atomize liquid materials, and evaporates the mist droplets through hot air to achieve rapid drying. This type of dryer is suitable for smaller production scales and lower material handling volumes.

Pressure spray dryer: Atomizes liquid materials under high pressure and dries them with hot air. This kind of dryer is suitable for larger production scale and higher material handling capacity.

Rotary spray dryer: The liquid material is atomized through the rotating atomizing disk and dried by hot air. This dryer is suitable for processing materials with larger particles and can achieve uniform drying of particles.

Spray bed dryer: The liquid material is evenly sprayed into the hot air flow through a sprayer to form a suspended state, and then dried by the hot air. This dryer is suitable for drying viscous or sticky materials and can achieve uniform distribution of particles.

Spray freeze dryer: Spray liquid materials into a low-temperature environment and dry them by freezing and evaporating. This dryer is suitable for processing heat-sensitive materials and can retain the activity and quality of the materials.
