Introduction of Fluid Bed Dryer (FBD)
Fluid Bed Dryers (FBD Machine) or Fluidized Bed Dryers are designed to Uniform drying of the material at low temperature. Fluid Bed Dryers are made of Stainless Steel 304/316 with GMP standards. The complete unit is supplied with Suitable motor, blower, filters, filter bag, control panel. Heating system provided as per specific customer requirements. Our range includes Laboratory R&D Fluid Bed Dryer 10 kg to Industrial Fluid Bed Dryer 500 kg fluid bed dryer. Our range includes 30 kg fluid bed dryer, 60 kgs fluid bed dryer, 120 kgs fluid bed dryer. Fluidized Bed Dryers uses for drying powder, granules & pellets on low temperature. We manufacture GMP Fluid Bed Dryer for pharmaceutical industry and Standard Fluid Bed Dryer for Chemical Industry.
The pharmaceutical industry makes considerable use of fluid or fluidized bed dryers to lower the moisture content of raw materials like powder and granules. The fluidization of the materials being fed into the apparatus is part of its operation. Through a perforated bed of moist solid particles, hot air at a high temperature and pressure is injected into the system in this procedure. Solids that are just a little damp are removed from the bottom and suspended in a stream of air (fluidized state). Once the moist solid and hot gases come into close contact, heat transmission starts to happen. The liquid is removed by the dry gas. Sometimes, the gas that is leaving gets recycled in part.

Fluid Bed Dryer Working Principle
A bowl-shaped stainless steel chamber with a removable, frequently perforated bottom makes up a fluid bed dryer. The air is introduced through this perforated bottom, and with the aid of heaters, the temperature of the air inside is raised. After filtering, the hot air is allowed to travel through the material bed. The system has a slot for the connection of a fan. The fan starts the air flow and keeps an eye on it. The machine’s operating temperature and air flow can both be adjusted.
With the expansion of the Fluid Bed Dryer bag due to airflow, powder particles begin to move turbulently. Due to constant exposure to dry air, the material becomes dry within. The material that now leaves the system is filtered once more.
Materials are processed using a wet-bulb temperature after they have dried at a consistent rate. This technique makes sure that the materials are dried under relatively low temperatures to low moisture content. Installing heat-exchanging panels or tubes, which account for 80% of the heat exchange process, will result in high drying results. The Fluidised Bed Dryer only needs a little amount of gas because it has a sizable heat exchange area. The sizes of each piece of system equipment used in the system are minimised to investigate this problem.

Process Operation of Fluid Bed Dryer
Fluid Bed Dryer is designed to introduce the hot air stream at the base of the product container which is filled with the material. Induced draught is created by means of blower and fresh air is sucked in to the unit. The fresh air is heat by means of electrical heaters or steam or thermic fluid heaters. This hot air stream expands the bed of material at certain velocity & creating turbulence in the product. The phenomenon is known as fluidisation and offer conditions which are almost ideal for drying. Fluidisation produces full agitation of solid particles and since each particle gets surrounded by hot air, heat transfer is extremely high and uniform. The product is dried fast without appreciable loss of heat. Filter bags prevent particles escaping from the dryer.
