Advantages of pressure spray dryers

- Jan 24, 2020-

1.The drying speed is fast, and the surface area of the material liquid is greatly increased after being atomized. In the hot air current, 95% -98% of water can be evaporated in an instant. The drying time only takes from ten seconds to tens of seconds, which is especially suitable. For drying of heat-sensitive materials.


2.All products are spherical particles with uniform particle size, good fluidity, good solubility, high product purity and good quality.


3.Wide range of application. Depending on the characteristics of the material, it can be dried with hot air or cold air. It has strong adaptability to the material.


4.Simple and stable operation, convenient control, easy to realize automatic operation.

The pressure spray uses the high pressure produced by the high-pressure pump to make the wet material eject from the nozzle. The inner surface of the nozzle is made into a spiral groove. The outlet is a cone angle of about 700. The wet material will form a spiral spiral along the groove. It moves in a circle and is ejected from the conical nozzle at a very high speed. The wet material droplets are elongated and thinned, and then a filament is formed, and then broken into mist droplets. The higher the spray pressure, the smaller the diameter of the nozzle hole, the smaller the sprayed droplets; on the contrary, the larger the droplets.
