In the field of industrial production, centrifugal spray dryer is a common equipment, its main role is to dry liquid materials into powder or particles through spray. Let's learn about the working principle, application range, performance parameters and advantages of the centrifugal spray dryer to help you better understand and use this important industrial equipment.

1、 Working principle

The centrifugal spray dryer mainly uses a rotating nozzle to spray liquid materials into small droplets. Under the action of centrifugal force, droplets are subjected to outward inertial force, which can throw them out and quickly disperse them in hot air. In the airflow, the moisture on the surface of the droplet begins to evaporate, and the heat required for the evaporation process is provided by hot air. When all the water in the droplet evaporates, what remains is dry powder or particles.

2、 Application scope

Centrifugal spray dryer is widely used in various industries. For example, in the food industry, we often see it used to produce milk powder, cocoa powder, etc; In the chemical industry, centrifugal spray dryer can be used to prepare catalyst, activated carbon, etc; In the pharmaceutical industry, centrifugal spray dryer can be used to produce various solid drugs.

3、 Performance parameters

The performance parameters of centrifugal spray dryer mainly include: processing capacity, drying temperature, air inlet speed, air outlet speed and energy consumption. The selection of these parameters mainly depends on the requirements of the production process and the properties of the materials. The parameters are shown in the figure:

4、 Advantages
