Fluidized bed apparatus (mixing, drying, rectifying, granulating, coating)
A fluidized bed dryer (powder dryer) performs drying, granulation, and coating of raw materials in a fluid state. Products different from conventional compaction granulation methods can be obtained. Drying, granulation, sizing, granule formation, coating. Improvement of fluidity and disintegration.

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.
Fluidization can be achieved with a small amount of air, allowing for the fluidization of submicron-level fine powders.
The "Vibrating Fluidized Bed Dryer" is a dryer that utilizes a vibrating fluidized bed device, which adds special vibrations to the fluidized bed to form a more stable and well-functioning fluidized layer while maintaining fluidization with a small amount of air (fluid), making it suitable for a wide range of applications. The types include "Vibrating Fluidized Bed Dryer," "Vibrating Filtration Dryer," and "Solvent Priority Removal Dryer." The "Vibrating Fluidized Bed Dryer" can prevent the occurrence of channeling and external scattering of strongly adhesive fine powders of less than 10μm due to vibrations and a small amount of gas, making it a cost-effective drying device in terms of equipment and running costs. The "Vibrating Filtration Dryer" is a device that performs filtration and drying in one machine by dewatering and filtering slurry materials under pressure or vacuum within the unit. The "Solvent Priority Removal Dryer" is a drying device that removes organic solvents (such as methanol, ethanol, IPA, acetone, pyridine, etc.) remaining in powders that are strictly regulated.
