The solution, emulsion, suspension liquid or slurry are sprayed into fine beads in the hot air, going down from the top of the drying chamber to the bottom, the water will be evaporated to and the product becomes powder or granular product.

Induce hot air from the top of drying tower, at the same time, pump the material liquid to the top of the tower by screw pump or peristaltic pump, the feeding solution becomes into fine beads or small droplets through the atomizer. When the droplets meet the high temperature hot air, the water will be evaporated immediately, and the material liquid is dried into dry product in a very short time, the product is discharged from the bottom of the drying tower, or from the cyclone (depend on the configuration). When the hot air contacts with the droplets, the temperature declines significantly, and the humidity increases greatly, and then will be exhausted by exhaust fan. The fine powder in the air will be collected through different separating devices

There’re different fine powder separation and recovery devices, such as cyclone (the common type and various combination type), bag filter, cyclone + bag filter, cyclone + wet scrubber, and bag filter + wet scrubber etc. We should different fine powder separation and recovery devices as per the characteristics of product and requirements of customer.

Depend on the product features and requirements, we might install secondary drying and cooling system (such as ZLG vibration fluid bed or pneumatic transportation), formulation system or powder sieving system etc after the spray dryer, or dehumidifier.

At a high speed of drying ,after the spraying of the material liquid, the surface area of the material will be increased greatly. In the hot-air flow, 95%~98% of water can be evaporated at a moment. The time of completing the drying needs only several seconds.

This is especially suitable for drying the heat sensitive materials.

Its final products own the good uniformity, mobility, dissolving capacity. And the final products are high in their purity and good in their quality. The production procedures are simple and the operation and control are easy.

The liquid with the moisture contents 40~60%(for special materials, the contents may reach 90%) can be dried into the powder of particle products once a time.

After the drying, there is no need for smashing and sorting, so as to reduce the operation procedures in the production and to enhance the product purity. The product particle diameters, looseness and water contents can be adjusted through changing the operation condition in a certain scope.

It is very convenient to carry out the control and management.
