A result of the mixing is excellent temperature stability and increased mass-transfer and reaction rates. The method is also quite complete and there is a lack of understanding of behaviors of the materials. Fluidized Bed. Trickle bed reactors are named as such for their operation in a trickle-flow regime. Below are the main advantages of fluidized bed dryers in the pharmaceutical industry: 1.Fluidized Bed Dryers Guarantee Fast and Homogeneous Drying 2.Fluid Bed Dryer is Suitable for Heat Sensitive Products 3.Fluidized Bed Ensures Efficiency in Material Drying Good mixing. Types 4. Ideally, these are the main challenges you may face when intending to use this equipment. Principle of Working of Fluidised Bed Combustion 3. And many more it’s advantages during operation time. Therefore, sticky or adhesive materials will not move freely, hence it will be nearly impossible to use this equipment. Still, I am eager to know the advantages of BFB that we can work with. List advantages and disadvantages of fluidized beds… Even with the high rate of mass and heat transfer, you can still control the basic parameters that affect quality of the final product. 3. Because of this a lot of aquarists prefer to run an air stone in the main systems to compensate. As they do not remove the CO 2 content, they will not bring oxygen into the water, and indeed the bacteria will consume some of the oxygen. A fluidized bed combustor can respond to changing heat demands more easily than stoker fired systems. That is, with the modern control system, you can adjust all parameters of the inlet air flow. Fluidized bed reactors are heterogeneous catalytic reactors in which the mass of catalyst is fluidized. The advantages of vibrating fluidized bed are as follows: (1) The heat and mass transfer coefficient of the two phases is higher than that of the fixed bed, which can shorten the time and improve the production capacity of the equipment; However, non-granular samples cannot be dried using fluidized bed drying. Rotary dryers are known for their ability to take what is given, b… Ideally, you don’t have to worry about product contamination, dust pollution, rust or tedious cleaning process. Bed-fluid mechanics not well known. Apart from these 8 advantages of fluid bed dryer, other includes: Even though a fluidized bed dryer may offer all these advantages; it may not be suitable for all pharmaceutical applications. Furthermore, a vigorous movement may generate electrostatic charges. The reactor can also operate at a continuous state with a fluidized bed. Heterogeneous has phase reactions with a catalyst: 1. Hot air or gas reaches every surface of the particles. Increased reactor vessel size: Because of the expansion of the bed materials in the reactor, a larger vessel is often required than that for a packed bed reactor. Also, because the fluidized material is solid, this leads to some erosion of the components inside. Rotary dryers have been called the “workhorse” of the industrial drying industry, due to their heavy-duty construction, their high-capacity capabilities, and most of all, their ability to accept a significant variance in feedstock. Contents: Introduction to FBCs Principle of Working of Fluidised Bed Combustion Types of FBC Systems Pressurized Bubbling Fluidized Bed Boiler (PBFB) Advantages of FBC […] Fluidized Bed Reactor - Basic Mechanism, Mass Transfer in Fluidized Beds, Reaction Behaviour in a Fluidized Bed, Mole Balance on the Bubble, the Cloud, and the Emulsion, Advantages & Disadvantages, Current Applications of FBR. In short, I highly recommend fluid bed dryer in pharmaceutical applications due to these numerous advantages and predictable performance. This in turn increases the operating cost … The advantages and disadvantages of the electrostatic spraying process and fluidized bed process are compared below. Whenever you are using fluid bed dryer in the pharmaceutical industry, you’ll experience some challenges. Furthermore, there are those that have wheels, making them portable material processing equipment. Others challenges may include: The good news is that most of our machines do not have these problems. Advantages and Disadvantages of the Fluidized‐Bed Reactor 2. This is usually accomplished by introducing pressurized fluid through the particulate medium. Currently, as a fluid bed dryer manufacturer, we try to eliminate this problem by installing precise control mechanisms. Do you need a drying machine for both batch and continuous material processing? However, it is important that you choose a suitable machine that matches the exact requirements of your applications. 2. With this control panel, you can easily monitor the temperature and air flow settings. Furthermore, with the modular design, you can easily replace or modify this machine to suit your unique applications. Gas distribution. Pressurized Bubbling Fluidized Bed Boiler (PBFB) 5. ● High potential for attrition; and in some cases agglomeration of fine particles. The Fluidization Principle 1.2. 2. In this fluidized state, the particle you intend to dry is actually in direct contact with the hot gas or air. Good uniformity of temperature. In view of all these advantages of fluidized bed combustion above, where fluidized bed combustion emerges as the best alternative available today, still the major drawback of this system is that the fan power has to be maintained at a considerably high value, since the air has to be supplied continuously at a very high pressure for supporting the bed. The increase in fluidized bed reactor use in today’s industrial world is largely due to the inherent advantages of the technology. After this, the medium will have many similar characteristics and properties as fluids, such as the ability to free-flow under gravity. This makes fluid bed dryer a perfect choice for most laboratory and R&D applications. Coal power plants sometimes use fluidized bed systems which can captures sulfur pollutants to burn coal more efficiently. Remember, hiring untrained personnel will make your warranty invalid. The advantages of fluidized bed drying include low investment and maintenance costs, large-scale continuous production, lower air temperatures than spray drying and a relatively short drying time compared to freeze drying and vacuum drying (Bayrock and Ingledew, 1997). Unlike other systems the require expensive cleanup and monitoring equipment, fluid bed powder coating is simple and straightforward. The equipment is made from high quality stainless steel. There are a few disadvantages to using fluidized beds. ● High pressure drops results as a result of the need to suspend the entire bed in the gas which equally leads to high energy consumption.
