Fluid Bed Dryer

Fluid Bed Dryer

We are the leader in designing the fluidized bed dryer as our FBD helps in the process of drying and cooling of heat sensitive medicines by reducing the moisture content in a given time. It also finds its use in the chemical, food, biochemical and dairy industries.

Shree Bhagwati Mechtech (India) Pvt. Ltd.Fluid Bed Processing involves fast drying, cooling and agglomeration of particulate materials. It is ideal for heat sensitive and non heat sensitive products in Pharmaceuticals, Chemicals and Biochemical, Food and Dairy Industries. The Fluid Bed Dryer have a bed of solid particles which are fluidized by passing a stream of air 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 particles. The air is heated and the process hot air evaporates the fluid and dries the solids. Fines get agglomerated to larger granules particles thus providing large size.

The machine is designed with correct volume of bowl, air velocity, direction and the temperature of the clean inlet air is maintained throughout the fluidization, retarding, and expansion chambers, filtration area, pitch of the perforations of the plate at the bottom of product container, the leak-proof fluidization space by proper sealing, material of the filters and process controls with electrical & pneumatically.

The uniform drying is achieved by exposing the full surface of every particles of the solid mass to the incoming high velocity hot air.

Option for the process parameters are controlled by using latest PLC controls with HMI touch screen thus making equipment operationally safe and eliminating the possibility of human error. The process consistency with batch records is maintained for every batch every time.

The equipment can be inbuilt CIP system gives a thoroughly cleaned equipment for every batch eliminating contamination of subsequent batches.
