Fluid Bed Dryer - Lab Fluid Bed Processor, Fluidized Bed Drying Machine


Fluid bed dryer

is used for drying the product at desired temperature like wet powder that is been produced by the hot air of the fluid bed dryer moving in upward direction. In order to acquire uniform temperature & high heat transfer rate, the granules are fully fluidized with the help of electrical hot air or powerful steam. For uniform drying of the granules or powder, the unique design of the fluid bed dryer does it without any racking process. The fluidized bed drying technology is been used in different industries including the powder processing industry, pharmaceutical industry that has proved many advantages to the industries. The method of the fluid bed dryer has reduced the tray drying process & time as compared to uneven drying in trays. Hence, fluid bed dryer is the energy saving solution for drying of your product. This fluid bed dryer has a sturdy built because of its 2 bar construction. Moreover, the material used in its construction of this high tech machine is flameproof. This fluidised bed dryer is widely used in the drying of powders, mixing of powders and agglomeration in pharmaceutical, chemical, foodstuff, dairy and many other process industries.

What is a fluid bed dryer?
Fluid Bed Dryer, also known as fluidized bed dryer, is a type of equipment used to reduce the moisture content of the powders and granules. FBD is widely used in Pharmaceutical, Chemical, Food, Dairy, Dyes, and other process industries.

How does a fluid bed dryer work?
First the material is fed on the shaking steel bed through which hot air flows. The high pressure hot air flow fluidizes the bed of material by contacting each particle. The airflow is controlled throughout the length of the dryer to maximize fluidization to handle wet and sticky materials. As the material starts passing through, it loses the moisture gradually until the desired dryness is achieved. Once the desired dryness is achieved, the material is passed into a cooling zone. In this stage, the hot air is replaced by the cool air that reduced the temperature to the required point.

What is the FBD principle?
FBD (fluidized bed dryer) works on the principle of fluidization, wherein hot air is introduced into the spaces between solid particles. In the fluidization process, hot airflow is introduced at high pressure through the bed of moist solid particles. The hot air moves upwards through the spaces between these particles. With increasing velocity, upwards drag force on the solid particles increases and at one stage it becomes equal to the gravitational force. Therefore, the bed is known as fluidized and the particles are suspended in the fluid.

What is the function of Fluidized Bed Dryer?
Fluid Bed Dryer, also known as FBD, is a very important type of equipment used in the granulation area of various industries. Its primary application is in the granulation process for drying the material and to achieve desired moisture content in the granules.

What is SFM in FBD?
Solid Flow Monitor (SFM) is advanced equipment to monitor and control flow rate, resulting in a smooth and efficient flow of material. Solid Flow Monitor test reliably detects filled bag failure in FBD and helps in preventing product loss. SFM is located in the exhaust duct of the Fluid Bed Granulator.

What is a fluid bed processor?
Fluid Bed Processor, also known as fluid bed granulator, is an advanced type of equipment for drying, cooling, agglomeration, granulation, and coating of materials with high efficiency. Fluidized bed processor is widely used in the pharmaceutical, chemical, food, and other related industries for drying, granulating, coating, and palletizing.
