Drying, heating, cooling
The NARA Fluidized Bed Dryer (FBD) provides high efficiency by fluidizing powder with gas. It is suitable to uniformly dry the processed material which ranges in high moisture content to low moisture content. The wet powder is dried by a fluidized bed incorporating a heat exchange with gas. The air entering through a sieve, creates a powder charged air, causing an effective mass / heat exchange, as well as good mixing of the powder. The moisture content of the powder is picked up by the air flowing through and discharged, via cyclone and filter. The Fluidized Bed Dryer is used in many broad applications and industries, such as food, feed, fertilizers, pharmaceutical and plastics industries.
NARA’s Batch Type Fluidized Bed Dryer (B-FBD): Hot gas is supplied from the bottom of B-FBD through the perforated plate to fluidize and dry the powder materials. Feeding, drying, and discharging processes are repeated in a batch process. There are two options in the discharging process; Option 1, is rotating the perforated plate by a control motor and discharging all the material into the bottom hopper. Option 2 is by utilizing a centrifuge stream generated by a directional type perforated plate to discharge all of powder from the wall of the B-FBD.
