Fluidized bed dryer provides a significant drying amount and the material is dried in a very small time. Content continues to be free-flowing and uniform.
On the other hand, the solid particles are blown-up and remain suspended during the air channel, If air is allowed to flow by way of a mattress of strong substance during the upward course that has a velocity higher when compared to the settling fee from the patches.
The air is filtered through the filter after which passes with the mattress of the fabric at the bottom.
Inlet air is blown up in the static energy bed as being the velocity from the air will increase so does the Room among powder particles until the particles turn into suspended in a very mattress the fluidization course of action is through to occur in five phases which includes sleek fluidization, bubbling fluidization, turbulent fluidization and initially fluidization.
The Blower is switched ON through the control panel. Since the blower results in being operational so it draws the air repeatedly from Air Heating Device and into the tower in the lower plenum.
This condition is called fluidized condition. Each individual granule is thoroughly dried because of the as, which envelops them.
In fluidization system, sizzling air is launched at high force by way of a perforated mattress of moist reliable particulate.
HMI is actually a human-equipment interface. It's really a touch monitor the place the operator gives Guidance to FBD to alter the parameters. Each of the parameters like inlet air temperature, outlet air temperature and so forth. is controlled by HMI of fluid bed dryer.
simultaneously coating Option spray is finished on granules to coating them with the assistance of top rated, bottom, and tangential spray furnished Together with the chamber device.
This reduction in velocity allows the dried solution particles to settle after which you can be discharged from your dryer, ordinarily by way of an automatic discharge valve.
It helps in the improvement of different product properties such as compressibility and stream skill.
This mixture of reliable particles and air behave similar to a liquid, and the stable is said to get fluidized. This technique get more info is more successful with the drying of granular solids. In this method Every single granule is surrounded by very hot air, so the material is efficiently dried.
Commence-up: The FBD is begun, as well as a stream of preheated air is launched into your drying chamber from the bottom. The velocity on the air is carefully controlled to initiate fluidization with no entraining a lot of particles.
Air from processing unit arrives in the provide duct and enter into a bowl of FBD or fluid mattress dryer as a result of Air website gate. Air gate is managed by HMI to open and close it. When it's opened air enters to the bowl of fluid mattress dryer and when it truly is shut air entry is likewise stopped.
