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. Material of Construction (MOC) Offered : - CS (IS 2062 Gr A/B, SA 516 Gr 60/70, BQ), SS 316, SS 304, SS 316 L, SS 304 L. SS 310, MONEL, INCONEL, TITANIUM, HASTALLOY ETC.

CONTINEOUS FLOW VIBRATING FLUID DRYER-ROASTER COOKER Fluidization of wet materials such as tea, grated coconut, spices and any Granular / powder is not possible by air alone. The SAKAV VFBD uses a combination of Vibration and a Special Air Distribution plate to effectively fluidize such materials. Compact design of the SAKAV VFBD enables single pass drying, making it an ideal and fuel efficient drying equipment. SAILENT FEATURES Robust design / Long life Hygienic construction Minimum space requirement Suits any heater / fuel Easy to operate MACHINE DESCRIPTION :- The Machine consist of a Vibratory Conveyor over which is moulded either a gas fired infra red manifold. or an electrical manifold, or any other HotAir Media, steam, Gas etc. The material is fed onto the vibratory conveyor from a feed vibrator controlled by a rheostat. As the material pass under the infra-red burners they are subjected to a continuous vibration in order to turn the material over many times. This enables all the material to receive an equal amount of of infra-red burners can be varied so that the material can be dried, roasted or for various periods, in order that the materials may reach an internal temperature. The hot material are then immediately elevated into an insulated maturing holding bin. where they continue to cook with their own residual heat, for predetermined periods which can be varied as desired. Depending on the final reduction of moisture. A measured quantity of material is fed onto a specially designed stainless steel perforated vibrating plate mounted on an aerodynamically designed plenum chamber. The entire assembly of plenum chamber and perforated plate is suspended on spring and vithrealed with electric Balanced Meter. Hot air from the heat source is sucked in and forced through the plenum chamber by a hot air blower. The plant is complete with feed hopper, electrical control, cooler, insulated maturing holding bind, cooling fan. cyclone and airtrunking. GAS FIRED INFRA RED BURNERS AVAILABLE. OUTPUT :- Output from 25 Kgs. / Hr. to 2 Tones / Hr. Heating Capacity varies from machine to machine depending material, Drying Time & etc. CONSTRUCTION :- All parts in contact with the product are in Stainless Steel constructions. The entire vibrating bed assembly is encased in a rugged self-supporting casing of channel frame construction

The Vibratory Fluid Bed Dryer Manufacturer is used for fluidization of materials which are often characterized by having one or more of the following physical properties: Wide particle size distribution Low strength of wet or dry particles Stickiness or thermo plasticity of the particles Pasty properties of the wet feed In the Vibratory Fluid Bed Dryer Manufacture, the material is easily transported through the dryer by the combined effects of fluidization and vibration. The fluidization velocity can be judiciously selected to minimize entertainment of the smaller particles, to avoid gas bubbling m the fluid bed thereby minimizing attrition. The residence time can be adjusted, by varying the bed height, through the overflow weir position. A cooling section can also be provided, by partitioning of the plenum chamber. Vibratory Fluid Bed Dryer Manufacture have a bed of solid particles, which are fluidized by passing a stream of air or gas upward through a specially designed perforated sheet. The upward velocity of air is so maintained so as to slightly lift the solid particles and set them in motion. This motion can be utilized to bring about mixing as well as forward movement of the solids. The air or the gas is heated and the heat is utilized to dry the solids. Fines get agglomerated to larger particles thus providing large size granules. Voice Engineers is a Our wide-ranging technology and supply program means that we can combine our dryers and screening machines to make economical complete plants, e.g. for manufacturing potato granulate. Vibratory Fluid Bed Dryer Manufacture are supplied as continuous dryers or batch dryers. As vibration dryers, they adapt to the specific properties of the products to be processed and to the process management particularly effectively. APPLICATION : Drying or cooling, process for salts, chemicals, Tea, cereals and Milk products (used as a secondary dyer)
