VIBRO-FLUIDIZER™
GEA Niro’s VIBRO-FLUIDIZER™ has proved that it is by far the most efficient and sanitary vibrating fluid bed dryer on the market. It is a vibrating fluid bed of the plug flow type. The VIBRO-FLUIDIZER™ can be operated as a separate drying or cooling unit for powders or agglomerates, but is usually used in combination with a spray drying plant such as the Multi-Stage Dryer MSD™, Fluidized Spray Dryer FSD™, COMPACT DRYER™, or TALL FORM DRYER™, or together with a back mix fluid bed in specialty dryers such as the lactose dryer and the TIXOTHERM™ dryer.

How does the VIBRO-FLUIDIZER™ work?
The moist powder layer is vibrated on an air distributor plate. The effect of the vibration combined with the upward and forward directed flow of drying air through the perforated plate creates ideal processing conditions and powder transport. Thanks to the vibration, it is possible to operate with fluidized powder layers of less than 200 mm. This gives a narrow and controlled residence time that is short and attrition is avoided.
The air distributor plate is fully welded directly to the fluid bed housing and there are no hollow spaces in the construction. This makes the VIBRO-FLUIDIZER™ the only true sanitary vibrating plug flow fluid bed available on the market.
The perforation of the air distributor plate design is selected according to product application and it is possible to determine the angle and direction of the forward directed airflow. This makes the VIBRO-FLUIDIZER™ a very efficient after drying unit where the powder comes close to the equilibrium of the incoming drying air. Further, it is self-emptying.
The VIBRO-FLUIDIZER™ can be equipped with integrated retractable CIP nozzles for a complete and efficient CIP wet cleaning with very short turnaround time.
