Fluid Bed Dryer, fbd dryer, bed dryer, fluid bed dryer
Fluid Bed Dryer is designed for fast and uniform drying of powders, crystals and medium sized pellets. The Fluid Bed Dryer finds application in Pharmaceuticals, Bulk Drugs, Dyes & Chemicals, Phyto-Chemicals, Catalysts, Food Products & Starch derivatives, Pesticides etc.
Fluidization principle. A high-pressure Hot air from the supply is passed through the perforated container containing wet granules. As the hot air passes through container granules start to suspend in the air to become dry (called a fluidized state), the process is called fluidization.
fluid bed dryers and processor are manufactured in modular construction mainly consisting of main processing (drying) unit and separate inlet air preparation unit and separate exhaust air unit giving flexible and alternative installation option to the customers as per requirement.
Fluid bed dryers are most suitable for drying granules, crystalline, coarse or similar material in pharmaceuticals, fine chemicals, dyes, foodstuff and allied industries.
Fluid bed processing involves drying, agglomeration, granulation, and coating of particulate materials. It is ideal for a wide range of both heat sensitive and non-heat sensitive products. Uniform processing conditions are achieved by passing hot air through a product layer under controlled velocity conditions to create a fluidized state.
Using intimate air-to-product contact, Drying is carried out by heated air supplied as main the source for drying, as it is effectively introduced by steam heating which gives high rates of heat exchange at high thermal efficiency while preventing overheating of individual particles.
Fluid bed coating of powders, granules, or tablets involves the spraying of a liquid on the fluidized powder under strictly controlled conditions. It is ideal equipment that is in conformity with the requirements of cGMP.
A fluidized bed dryer is widely used in the granulation area of Pharmaceutical manufacturing. Granulation is a technique to dry the material in order to get the desired moisture content so that the manufactured medicines pellets are perfectly compressed.
Fluid Bed Dryer has a high drying rate, therefore, the material gets dried very quickly. Because of this property, this machine proves very useful in giving out high output.
Fluid Bed Dryer has been put in use to create synthetic resins. This machine can also be used in food, fertilizers, ceramics, Agrochemicals, etc. There is a machine type called B-FBD and this one is suitable for the material which requires drying in the decreasing-rate drying zone.
Features of Fluid Bed Dryer
The Fluid Bed Dryer is a versatile piece of equipment extensively used in the pharmaceutical industry to reduce moisture content in raw ingredients. It offers several features that make it an efficient and reliable choice for drying processes. Here are the key features of the Fluid Bed Dryer:
- Fluidization Principle: The equipment operates on the principle of fluidization, where hot air at high temperature and pressure is introduced into the system through a perforated bed of moist solid particulates. This fluidization process allows for efficient heat transfer and moisture removal.
- Stainless Steel Construction: The Fluid Bed Dryer is constructed with a stainless steel chamber, ensuring durability, resistance to corrosion, and easy cleaning.
- Perforated Bowl: The equipment includes a detachable bottom, often referred to as the bowl, which is perforated to allow the passage of air. This design promotes uniform airflow distribution and efficient drying.
- Controlled Airflow and Temperature: The Fluid Bed Dryer features an air intake system with heaters to increase the temperature of the air inside. The airflow direction, rate, and temperature can be controlled and regulated for optimal drying conditions.
- Turbulent Motion and Uniform Drying: As the air flows through the bed of material, the powder particles start a turbulent motion, ensuring uniform exposure to dry air and efficient drying of the material.
- High Drying Rate: The Fluid Bed Dryer offers a high drying rate, allowing for quick moisture removal and shorter drying cycles. This feature enhances productivity and output.
- Filtering System: The equipment is equipped with a filtering system to prevent the release of fine particles and ensure the quality of the dried material.
- Wide Range of Applications: Fluid Bed Dryers find applications not only in the pharmaceutical industry but also in other sectors such as food, fertilizers, ceramics, agrochemicals, and synthetic resin production. They are particularly effective in the granulation process for pharmaceutical manufacturing.
- Energy Efficiency: The design of the Fluid Bed Dryer includes heat exchanging tubes or panels, maximizing the heat exchange process and reducing the required gas amount. This promotes energy efficiency and cost savings.
- Compact Design: The equipment is designed with minimized equipment sizes, maximizing the heat exchange area within the dryer. This compact design ensures efficient and space-saving operation.
The Fluid Bed Dryer offers reliable and efficient drying capabilities, enabling the production of high-quality materials with controlled moisture content. Its versatility, high drying rate, and energy efficiency make it a preferred choice in various industries, particularly in pharmaceutical manufacturing and granulation processes.
CAPACITY: Fluid bed dryer/ Fluid bed processor comes with range of capacities as per our customer’s requirement.
Capacity range: – 5 Kg to 1000 Kgs
The wet material is loaded into the product container which is provided with air distributor plate and Dutch weave mesh. Fresh air-to-product-contact is filtered by means of 3-Way filtration process i.e. through coarse filter, 5-micron filters and the HEPA Filter is heated by means of heater (steam or electrical). This hot air then passes through the product container, creating turbulence in the product and hence product moves up and down in the product container. Due to this the heat transfer is quick and the product is dried fast without appreciable heat loss. Filter bag prevents particle escaping from the dryer.
Suitable for drying humidity from powder raw material in Pharmaceutical, foodstuff, feed, chemical industries, etc
Semi-liquid materials, large granules, small blocks and adhesive material.
The materials that volumes vary during drying process.
Fluid bed Dryer can be supplied with Upgradation to be used as processor (Vertical Spray Granulation)

Material to be dried is placed in a detachable vessel at the bottom of the dryer. The air is introduced from below through the prefilter, heated utilizing heaters installed therein. Simultaneously fan is also allowed to work. As the air velocity increases, the bed expands, and further growth causes turbulent motion of particles called fluidization.
