Fluid Bed Dryer
Static Bed Fluidized Bed Dryer is a very critical equipment where there is no moving part inside the Drying Chamber. The Salt is fluidized, each particle meets the hot air, discharges moisture, gets dry and at the same time travels forward without any mechanical push. It is meticulously handled by the balancing of the hot air through drying fan, cold air through cooling fan and exhaust air through exhaust fan. This balancing art requires very special skill in Design and Operation. We have proven-technology for designing dryers of any capacity. Since we have basic design knowledge of such dryers, we can offer the best services to our clients in case of difficulties during operation. In salt plants we suggest to go for SS 316L as MOC for such Dryers.

Vibratory Fluidized Bed (VFB) is another type of fluidized bed where the mechanical vibration, enhance the performance of fluidization process. Since the first discovery of vibratory fluidized bed, its vibration properties proves to be more efficient in dealing with fine particles which appears to be very difficult to achieve with normal fluidized bed. Even though numerous publications and its popularity in industrial applications, the knowledge about vibratory dynamics and properties are very limited. Future research and development are needed to further improve this technology to bring it to another level.Standard type of vibratory fluidized dryer consist of vibrating tray conveyor where hot gases from the chamber will flow through the holes within the tray and come in contact with the materials to be dried. The tray area is big enough to tolerate constant flow of material through the bed and passed along the deck with a low depth on the tray. The vibrations to the deck are directed in vertical component to assist in fluidization of the material whereas the horizontal component of the vibration, support in transporting materials along the tray.Some of the advantages of vibratory fluidized beds include: Continuous drying throughout the unit. Handle products with a wide range of particle size and shape. Minimal fluidization velocity and pressure drop due to the vibration energy being transferred along the bed. Increase efficiency of gas to solid contact. Mechanical vibration enhances homogeneity and stability of fluidized bed layers. Easier to control the residence time distribution of processed material by manipulating the intensity of amplitude and frequency of vibration. Limitations of vibratory fluidized bed are as follow The inlet air temperature to the dryer process is limited. Climate condition can affect the unit’s thermal efficiency. Build-up of local expansion region lead to unstable behavior to the bed structure.
