There are several types of spray dryer nozzles:
Spray dryer nozzles mainly include centrifugal, compressed gas atomization, electrospray, vortex and other types.
Centrifugal nozzles produce atomization effects through centrifugal force and are suitable for spraying materials with high water content. Compressed gas atomization nozzles use compressed gas to atomize materials, and the spray effect is very fine, but an external compressed gas source is required. Electrospray nozzles break down liquids into tiny particles through electric field force and spray them out through high-speed airflow. The spray effect is also very fine, but the price is relatively high and a stable power supply is required. Vortex nozzles are designed with optimized structure to form a vortex spray, which can reduce the size and splash of droplets and are suitable for spraying agents of different viscosities. Other types include nozzles with multi-layer belt type, multi-stage type and other structural forms, as well as high-speed centrifugal atomization, pressure type and other nozzles classified according to the atomization type. These nozzle types have their own characteristics and are suitable for different materials and drying needs. Choosing the right nozzle type requires considering the nature of the material, the required particle size and distribution, and the specific design and application of the dryer.
