The fluid drying machine or FBD machine is widely used in the pharmaceutical, food and chemical industries to dry the wet granules produced in the material mixing stage. The basis of the operation of this device is based on the passage of hot air fluid through the moist granule. Passing hot air through the mesh built into the device and lifting the material ensures excellent heat transfer and high drying speed. Fabric filters built into the device prevent material from passing out of the device. Also, this device is used to spray paint solution or glue to color the product or make granules.
