Basic principle

Spray drying is the use of raw materials will be dispersed as droplets of liquid atomizer, and hot gas drying droplet and obtain product method. According to the raw material liquid atomization by means of spraying dryer can be divided into three kinds of dance:

The 1 airflow atomizer adopts compressed air at very high speeds is ejected from the nozzle ( & 300 m / s ), relying on the gas-liquid two phase velocity difference generated by friction, so that the liquid is split into droplets.

2 pressure atomizer with high-pressure pump causes the liquid to obtain high pressure, high pressure liquid through the nozzle, the pressure energy into kinetic energy and high speed jetted dispersed droplet.

The 3 rotating centrifugal atomizer liquid material in high speed rotary disc ( circumferential speed of 90 ~ 160 M / S ) by centrifugal force from the disk edge thrown out and atomization.
