Apr 04, 2013 Fluidized bed dryer requires less time to complete drying. i.e., 20 to 40 min. Hot spots are not observed in the dryer, because of its excellent mixing and drying capacities. The thermal efficiency is 2 to 6 times greater than tray dryer. It facilitates the drying of thermolabile substances , since the contact time for drying is short.
The fluid bed dryer consists of an electric motor which powers the fan inside it. So what happens is that from the beginning of the process, the fan helps in sucking air inside from the surrounding. This air gets extremely hot given that it transverses through a heating system inside the dryer.
Apr 02, 2013 Fluidized beds are extensively used in the pharmaceutical and other chemical industries either as a batch or continuous process for drying moist powders and granular solids. This is due to good mixing of solids and intensive heat and mass transfer between the solid and hot gas phases in the system. Generally, high energy input is required during this process to
The fluidized bed has become widely used in drying systems in recent years. Fluidized bed dryers have been used for drying granular materials, pastes, solutions, suspensions, and molten materials in both a batch and a continuous dryer l In a fluidized bed dryer the bed is composed of the moist material to be dried with the fluidizing
The Fluid Bed is often used for drying and cooling of powder. The use of a Fluid Bed enables adjustment of process parameters in order to achieve a superior overall drying economy and powder quality.

Nov 28, 2019 1.1 Preface. The phenomenon in which solid particles float in a gas stream and have a liquid-like property is called a fluidized bed. This phenomenon of fluidization in gas or liquid flow was discovered by Fritz Winkler in the 1920s .This one was investigated by Lewis et al. and had been raised to fluidized theory .The first commercial fluidized bed dryer was
Fluidized Bed Cooler. J ST vibrating fluid bed coolers for bulk materials use convection to transfer heat to the cooling element, i.e. via direct heat transfer, so the heat transfer medium comes directly into contact with the product.
