High Speed Centrifugal Spray Dryer Design Points and Main Features
Mar 16, 2018

The high speed centrifugal spray dryer is a new type of high-efficiency drying process equipment. During the operation, the equipment can make the emulsion, paste liquid, solution and heat sensitive material spray-dried, generally within a few seconds. Evaporation of moisture into powdery, granular hollow spheres or pellets that meet production requirements is an ideal drying equipment for pharmaceutical biotechnology, chemical and other industries.

The feed liquid of the high-speed centrifugal spray dryer is fed into a centrifugal atomizing disk which rotates at a high speed. The equipment is subjected to the centrifugal force of the rotating disk. The material liquid is stretched as a film on the rotating surface and constantly moves to the edge, leaving the edge It has been atomized, and the atomized droplets (with a greatly increased surface area) undergo heat exchange with the hot air, completing the drying process quickly in 10-30 seconds.

High speed centrifugal spray dryer design points

1. There must be no vibration when the atomizer wheel rotates.

2. The rotation speed of the rotating disk must be high, the general rotation speed is 90 ~ 60M/S.

3. The surface of the liquid passage must be very smooth.

4. Uniform distribution of feed liquid on the fluid channel.

5. Uniform feed rate.

High speed centrifugal spray dryer features

1. The production process of high-speed centrifugal spray dryer is simplified, the operation and control are simple, and it is suitable for the continuous control of production, liquid with moisture content of 40-90%, once dried into powder, reducing crushing, screening and other processes to improve product purity.

2. The product has good dispersion, fluidity and solubility. The product particle size, looseness and moisture can be adjusted within a certain range by changing the operating conditions. The control and management are very convenient.
