Application of Fluid Bed Dryer

Drying in the Fluid Bed Dryer VJFBD-Lab makes use of the fluidized bed process, a technique similar to the one used in large industrial dryers. Ambient air is drawn in through a filter. A blower moves the air across the heating elements, and ultimately forces it through the perforated plate and into the detachable drying container. The solid particles are blown upward and dispersed and thus kept separate from one another. This helps to avoid a caking and sticking of the particles as it often occurs when other drying methods are used.

The air stream of the fluid bed dryer extracts moisture from the particles and then exits through the filter bag in the cover. Using the quick-clamp cover with the filter fleece insert is advisable when dealing with products finer upto 100 μm in diameter. The 1000 watt blower provides an air volume of 185 m3/h at idle speed; heater output is 2000 watts. The air volume, heating power and temperature are infinitely adjustable. Temperature control is effected using he display gauge.

Operation of Fluid Bed Dryer

The fluid bed dryer works on the principle of fluidization of the materials. In the fluidization process, hot air or gas flow is introduced through the bed of solid particulates, and this hot air moves upwards through the spaces between the particles, removing the moisture.

The following steps are involved in the fluidization process by VJ Instruments’ fluid bed dryer.

Material to be dried is placed in bowl type vessel.
The air is introduced from the bottom and heated at the required temperature by heaters.
The air is filtered through the filters and then passes through the material bed.
The air flow is generated by fans fitted in the equipment.
The airflow rate and the operating temperature are adjusted by the control panel.
As the flow of air increases the bed expands and the particles of the powders starts to rise up in a turbulent motion.
Regular contact with air causes the material to dry.
The leaving the FBD passes through the filters to collect the fine particles of the material.
FBD bags have finger link shape to increase the volume of the drying bed that helps to increase the drying rate and decrease the drying time.
The vaporized liquid is carried away by the drying gases.
