Design points and use characteristics of high speed centrifugal spray dryer
Jul 25, 2018

The liquid material of the high speed centrifugal spray dryer is sent to the high-speed rotating centrifugal atomizing disk. To a certain extent, it is mainly affected by the centrifugal force of the rotating disk. The liquid material stretches into a film on the rotating surface and continuously moves to the edge, leaving the edge. It has been atomized, and the atomized droplets (large surface area) are exchanged with hot air to complete the drying process quickly within 10-30 seconds.

Design points of high speed centrifugal spray dryer

1. The high-speed centrifugal spray dryer must have no vibration when the atomizing wheel rotates.

2. The rotating speed of the rotating disc of the equipment must be high, generally the speed is 90~60M/S.

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

4. Uniform feed rate.

High speed centrifugal spray dryer features

1. The high-speed centrifugal spray dryer has a fast drying speed, generally only 5-15 seconds, and has the characteristics of instantaneous drying (evaporation of 95%~98% of water in an instant). The material completes the drying process in a short time, adapts to the drying of the heat sensitive material, and can maintain the color, fragrance and taste of the material.

2. Simplified in the production process, simple operation control, to a certain extent, suitable for continuous control of production, liquid with 40-90% moisture content, dry to powder, reduce crushing, screening and other processes to improve product purity.
