Chemical and Foodstuff Spray Dryer
PRINCIPLE OF WORKING
Air is turned into hot air through heater and enters into hot air distributor at the top of dry chamber and then enters into dry chamber and rotates in the state of helix. At the same time liquid of raw material is sent to centrifugal atomizer at the top of dry chamber through stepless variable screw pump. In which liquid of raw material atomizes small drops. Air and liquid of raw material flow and contact each other. The moisture vaporizes rapidly. Liquid of raw material is dried into finished product in a short time. The finished product is discharged through the bottom cyclone separator of drier and the wasted air is exhausted through fan.
The drying speed is very quick. When raw material is atomized, the surface area increases greatly. 65~98% of moisture can be vaporized in hot air stream momentary. The dry time to be used is only 5~15 seconds. Especially, it is suitable for drying thermal sensitive raw materials.
The size of finished product is uniform and the flow and solubility are good. The purity and quality of product are good too.
The operation is stable and simple. The regulation and control is very convenient. It is easy to realize automatic operation.
The operation process is simplified and the operation environment is superior and can avoid powder dust during the period of operation.
