. The article contains sections titled: 1. Currently, as a fluid bed dryer manufacturer, we try to eliminate this problem by installing precise control mechanisms. Unlike other systems the require expensive cleanup and monitoring equipment, fluid bed powder coating is simple and straightforward. High pressure drops results as a result of the need to suspend the entire bed in gas which equally leads to high energy consumption. Describe how pressure drop and bed height (or void fraction) vary with fluid velocity. These disadvantages include: In fluidized state, particles are subjected to a turbulent state. The method is also quite complete and there is a lack of understanding of behaviors of the materials. Flow Through a Bed of Particles Response to Superficial Flow Fluid does not impart enough drag to overcome gravity and particles do not move. Pressurized Bubbling Fluidized Bed Boiler (PBFB) 5. High tar and dust content of the producer gas could result in problems while using the gas in the engines. Fluid bed dryer has a lot of advantages, but also not always the best for some clients. 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). However, there are instances where you will look for other alternative ways of drying material. Apply basic equations to compute pressure drop across the bed, the bed height and the diameter of the bed. Good mixing. Below are the main advantages of fluidized bed dryers in the pharmaceutical industry: Fluidized Bed Dryers Guarantee Fast and Homogeneous Drying. Contents: Introduction to FBCs Principle of Working of Fluidised Bed Combustion Types of FBC Systems Pressurized Bubbling Fluidized Bed Boiler (PBFB) Advantages of FBC […] 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. … This causes the particles to be suspended in the hot air or gas. Coal power plants sometimes use fluidized bed systems which can captures sulfur pollutants to burn coal more efficiently. Advantages and Disadvantages of the Fluidized‐Bed Reactor 2. Types 4. Do you know fluid bed drying is a popular material processing technique in the pharmaceutical industry? Gas plenum (Gas inlet chamber) which screws as the receiver for inlet fluidization air. There are a few disadvantages to using fluidized beds. Advantages 18. ● High rates of moisture removal due to an excellent gas-particle constant which results in high heat and mass transfer rates. ● 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. Fluidized bed reactors have been studied in several reactor engineering researches for OCM, also quite stable and efficient performance was reported especially in case of reactor operability and safety concerns. Again, due to the unique fluid bed dryer working principle; you can use this machine to dry thermolabile products. Advantages. Well, I can recommend a fluidized bed dryer since it is a machine that can handle both processes without necessarily doing expensive adjustments or modifications. Bed-fluid mechanics not well known. Principle of Working of Fluidised Bed Combustion 3. Due to the expansion of the materials in the reactor, the size of the vessel must be increased, which leads to a higher initial capital cost. Whether you’re in pharmaceutical, laboratory or R&D facility; there is that fluidized dryer design that will suit your unique application requirements. It is for this reason that we may advise you to consider other alternatives. In this article we discussed about the advantage of FBC (Fluidized Bed Combustion) boiler because of its grate verity of fuel combustion and grate fuel flexibility and higher combustion efficiency. Fluidized bed gasifiers. Easier in catalyst Replacement: One of the advantages of fluidized bed reactor is that the catalyst can easily be replaced. Advantages: Disadvantages: 1. The equipment is made from high quality stainless steel. All materials are suspended within the material drying chamber. With this information, you can comfortably choose the right pharmaceutical fluid bed dryer. The increase in fluidized bed reactor use in today's industrial world is largely due to the inherent advantages of the technology. For instance, if the initial moisture content is 30%, more time will be required compared to a material with a moisture content of only 10%. The increase in fluidized bed reactor use in today’s industrial world is largely due to the inherent advantages of the technology. Perhaps one of the greatest advantages of fluid bed powder coating is the relatively small investment that it takes to get a coating operation going. However, it is important that you choose a suitable machine that matches the exact requirements of your applications. Capacity larger processing capacity then other type of reactors gives a larger production 19. Gas-solid catalyzed: 1. Fluidized bed reactors are heterogeneous catalytic reactors in which the mass of catalyst is fluidized. This is a common phenomenon when drying organic powders. Unlike pack beds that have poor mixing, fluidized normally allows for a more uniform product compared to other reactor designs. Additionally, you can choose the right capacity of the fluid dryer where there is an excellent mixing of both the particles and air. Because of this a lot of aquarists prefer to run an air stone in the main systems to compensate. 5. However, for the case of fluid bed dryer, you can use high drying temperature.
