SHAKTI Fluid Bed Dryer offers an effective and efficient method for drying & granulating. It is invented keeping in mind the latest GMP norms with all contact parts AISI 316 Quality. By using modular construction and simplified design, we provide flexible installation.


It works on the principle of airflow. It takes time 20 to 45 minutes (Depends on products and percentage of moisturized).

The Fluid Bed Equipment have a bed of solid particles which are fluidized by passing a stream of filter air upward through a specially designed perforated sheet. The upward velocity of filter 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 particles. The filter air is heated and the process hot air evaporates the fluid and dries the solids. Fines get agglomerated to large size granules. The process is carried out continuously in batch size. The drying time and inlet air temperature can be set as per requirement of process and there is auto controlled for the same.
