Fluid Bed Dryer

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.

The Fluid Bed Dryer is designed to dry powders and granules used in pharmaceuticals, food, and chemicals. It removes moisture quickly and evenly, improving product quality and shelf life. Its advanced drying technology prevents clumping and maintains uniform consistency across batches.

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.

The fluid bed dryer is built with stainless steel (SS 304 or SS 316), making it resistant to corrosion and easy to clean. It follows Good Manufacturing Practices (GMP), which means it meets strict hygiene and safety requirements for pharmaceutical and food production. GMP ensures that equipment prevents contamination and maintains consistent product quality.

A compact and robust structure provides long-term reliability with minimal maintenance. The machine’s smooth finish prevents material build-up, reducing cleaning time between batches. It is ideal for industries requiring strict compliance with hygiene and safety standards.

How It Works

The fluid bed dryer uses hot air to dry materials evenly. The air is blown through a perforated plate that holds the material. As the air passes through, the granules or powders become suspended in the air stream, allowing moisture to evaporate efficiently. This method prevents overheating, making it suitable for heat-sensitive products.

A high airflow rate removes moisture quickly, preventing clumping and ensuring uniform drying. Since the drying process happens at controlled temperatures, ingredients retain their chemical properties without degradation.

Customizable Drying Settings

The fluid bed dryer allows operators to adjust temperature, airflow, and drying time based on the type of material. This flexibility helps achieve the best drying results for different powders and granules. A PLC-based control panel provides precise settings for consistency across batches.

The automated controls reduce manual monitoring, helping operators focus on other production tasks. A real-time display on the panel provides updates on temperature, moisture level, and drying progress.

User-Friendly Operation

Designed for ease of use, the fluid bed dryer requires minimal training. The automated drying cycle follows a preset program, reducing human error and ensuring uniform results. A quick discharge system allows dried materials to be removed efficiently, reducing downtime between batches.

The machine includes safety features to prevent overheating, excessive pressure, or system malfunctions. These built-in protections promise safe operation while maintaining consistent drying performance.

Additional Features

• HEPA filter (optional): Prevents dust from contaminating the environment
• Batch uniformity: Ensures even drying for all materials
• Quick material discharge: Speeds up batch transitions
• Low energy consumption: Optimizes power use for cost efficiency

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.
