Closed loop centrifugal spray dryer is a special equipment for drying organic solvent slurry. The equipment adopts explosion-proof design, and the drying process is safe and environmentally friendly.

working principle;

The ethanol closed cycle centrifugal spray dryer works in a closed environment. The drying medium is inert gas nitrogen, which enters the drying tower after being heated by a heater. Liquid materials are transported to the centrifugal nozzle through a screw pump. Ethanol is atomized into droplets by a high-speed circulating atomizer, and the heat and mass exchange process is completed in the drying tower. The dried powdery materials are discharged from the bottom of the tower. The evaporated organic solvent gas passes the dust trapped in the gas through the cyclone separator under the pressure of the negative pressure of the fan. The saturated organic solvent gas after dust removal of the spray tower is condensed into liquid through the condenser and discharged from the condenser. The non condensable gas medium is continuously heated and reused in the system as a drying carrier.

Features of explosion-proof closed cycle centrifugal spray dryer;

The drying medium in the drying system is N2, and the internal operation is positive pressure, maintaining a certain positive pressure value. If the internal pressure drops, the N2 inlet is automatically controlled by a pressure transmitter to ensure system pressure balance

Use of closed cycle spray dryer:

Mainly used in the drying process to prevent oxidation, the powder consistency after drying should be high, such as powders in industries such as pharmaceuticals, chemicals, food, lithium battery materials, etc. The solvent can be recovered during the drying process, and the drying carrier is recycled in the system
