The Fluid Bed Dryer finds application in Pharmaceuticals, Bulk Drugs, Dyes & Chemicals, Phyto-Chemicals, Catalysts, Food Products & Starch derivatives, Pesticides etc. Fresh air is drawn in by means of a fan. The air is then passed through a filter and heated to produce warm air by use of electric heaters. If the product contains a solvent or inflammable substances, the dryer must be operated using steam and provided with a flame-proof motor. The heated air passes through the product container which has diffuser plates and a sieve. Due to the stream of air, the wet product gets fluidised. The material gets surrounded by the hot air and gets dried due to heat transfer. Moist air passes through a filter bag and an exhaust duct. The Fluid Bed Dryer is not suitable for drying of liquids or pastes. We are among the most trusted firms, engaged in manufacturing, supplying and exporting Fluid Bed Dryer Machine. Designed in compliance with international quality norms, these products are manufactured using quality components and material, procured from the reliable vendors of the market. We also have R&D experts who conduct regular researches to improvise our Fluid Bed Dryer Machine.

Vibrated Fluid Bed Dryers:

Vibratory Fluidized Bed (VFB) is another type of fluidized bed where the mechanical vibration, enhance the performance of fluidization process. Since the first discovery of vibratory fluidized bed, its vibration properties proves to be more efficient in dealing with fine particles which appears to be very difficult to achieve with normal fluidized bed. Even though numerous publications and its popularity in industrial applications, the knowledge about vibratory dynamics and properties are very limited. Future research and development are needed to further improve this technology to bring it to another level. Standard type of vibratory fluidized dryer consist of vibrating tray conveyor where hot gases from the chamber will flow through the holes within the tray and come in contact with the materials to be dried. The tray area is big enough to tolerate constant flow of material through the bed and passed along the deck with a low depth on the tray. The vibrations to the deck are directed in vertical component to assist in fluidization of the material whereas the horizontal component of the vibration, support in transporting materials along the tray. Some of the advantages of vibratory fluidized beds include: Continuous drying throughout the unit. Handle products with a wide range of particle size and shape. Minimal fluidization velocity and pressure drop due to the vibration energy being transferred along the bed. Increase efficiency of gas to solid contact. Mechanical vibration enhances homogeneity and stability of fluidized bed layers. Easier to control the residence time distribution of processed material by manipulating the intensity of amplitude and frequency of vibration. Limitations of vibratory fluidized bed are as follow The inlet air temperature to the dryer process is limited. Climate condition can affect the unit’s thermal efficiency. Build-up of local expansion region lead to unstable behavior to the bed structure

Spray Dryer:

Spray drying is a method of producing a dry powder from a liquid or slurry by rapidly drying with a hot gas. This is the preferred method of drying of many thermally-sensitive materials such as foods and pharmaceuticals. A consistent particle size distribution is a reason for spray drying some industrial products such as catalysts. Air is the heated drying medium; however, if the liquid is a flammable solvent such as ethanol or the product is oxygen-sensitive then nitrogen is used.[1] All spray dryers use some type of atomizer or spray nozzle to disperse the liquid or slurry into a controlled drop size spray. The most common of these are rotary disk and single-fluid high pressure swirl nozzles. Atomizer wheels are known to provide broader particle size distribution, but both methods allow for consistent distribution of particle size.[2] Alternatively, for some applications two-fluid or ultrasonic nozzles are used. Depending on the process needs, drop sizes from 10 to 500 µm can be achieved with the appropriate choices. The most common applications are in the 100 to 200 µm diameter range. The dry powder is often free-flowing. The most common type of spray dryers are called single effect. There is a single source of drying air at the top of the chamber (see n°4 on the diagram). In most cases the air is blown in the same direction as the sprayed liquid (co-current). A fine powder is produced, but it can have poor flow and produce a lot of dust. To overcome the dust and poor flow of the powder, a new generation of spray dryers called multiple effect spray dryers have been produced. Instead of drying the liquid in one stage, drying is done through two steps: the first at the top (as per single effect) and the second with an integrated static bed at the bottom of the chamber. The bed provides a humid environment which causes smaller particles to clump, producing more uniform particle sizes, usually within the range of 100 to 300 µm. These powders are free-flowing due to the larger particle size. The fine powders generated by the first stage drying can be recycled in continuous flow either at the top of the chamber (around the sprayed liquid) or at the bottom, inside the integrated fluidized bed. The drying of the powder can be finalized on an external vibrating fluidized bed. The hot drying gas can be passed in as a co-current, same direction as sprayed liquid atomizer, or counter-current, where the hot air flows against the flow from the atomizer. With co-current flow, particles spend less time in the system and the particle separator (typically a cyclone device). With counter-current flow, particles spend more time in the system and is usually paired with a fluidized bed system. Co-current flow generally allows the system to operate more efficiently.
