Vibratory fluidized bed
Vibratory Fluidized Bed (VFB) is a type of fluidized bed where the mechanical vibration enhances 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.
==Introduction==
Vibratory fluidized bed technology has been around since its first discovery in 1984 by Geldart, where he conducted an experiment to observe the behaviour of different types of particle groups behave when vibration mechanism are introduced to further fluidized the particles.〔''() Fluidization of cohesive powders'', Geldart, D., Harnby, N., Wong, A.C., ‘Fluidization of cohesive powders’, Powder Technology, January 1984, 37(1), pp.25-37〕 Although it has been around for the past 20 years, only a few research has been done to further improve this technology. Recently, the world is focusing on environmental friendly machinery for the sustainability of the earth. Therefore more research has been conducted to study the effect of vibration in fluidisation because not only vibratory fluidized bed is environmental friendly, it is also cheaper compare to other fluidized bed.
