The spray drying machine is popular drying equipment, to make dry powder or granule from liquid, emulsion, paste liquid, especially for heat sensitive material.

It can keep color, original flavor of raw material, and the finished dry powder or granule have good quality,purity, fluidity.

It is of high accuracy & speed & efficiency, simple process, labor cost saving, widely applied in the industry of chemical, food, pharmacy, biochemistry, light industry,etc.


1.High drying efficiency. It only takes few seconds to evaporate 95-98% water in a hot air flow.

2. The finished power or granule is in a high purity and quality as well.

3. For material contains 40-60% water(special material can contain more than 90%), it can be dried into powder or particles once a time. .After the drying, there is no need for smashing and sorting.

Working Principle 

After filtering and heating,  the air enters into the air distributor at the top of the drier. Then the hot air enters into the drying chamber in the spiral spray at the top of the tower. The liquid will rotate and be sprayed into liquid beads. Through the very short time of contacting the heat air, the materials can be dried into the finished products. The finished products will continuously discharge through the bottom of dryer. The waste gas will be discharged from blower.
