3rd Separation Technology Award for the 1994 fiscal year (Separation Technology Discussion Group)
The fluidized bed creates a state similar to that of a fluid by blowing gas into a powder, suspending solid particles, and is used for operations such as drying, adsorption, and reactions. In conventional fluidized beds, the target for fluidization was powder particles of tens of micrometers or more. However, the "vibrating fluidized bed apparatus" can form a stable and good fluidized bed even with fine powders of several micrometers or submicron size, which were considered "difficult to fluidize," thanks to the synergistic effect of gas and vibration, while maintaining fluidization with a small amount of gas. This allows for a longer contact time between solids and gases, resulting in fewer particles being ejected. It has a wide adaptability to the shape of powders and can also be applied to wet materials. Additionally, it allows for the miniaturization or elimination of auxiliary equipment. Applications include drying, filter drying, humidification, reactions, surface modification, solvent removal, and classification, and it is particularly effective as a device for removing trace solvents contained in pharmaceutical powder raw materials. Uses include pharmaceuticals, food, resin powders, graphite, toner, ceramics, metal powders, spices, and fine chemical powders, with solvents prioritized for removal being acetone, ethanol, IPA, methanol, and pyridine. There are vertical VUA type and horizontal VHA type models available. For more details, please contact us or refer to the catalog.
