Nichiwa Chemical's spray drying technology
Stable production of granules around 50μm in a single process! We can handle cyclodextrin encapsulation.
"Spray drying" is a technology that instantly dries a liquid by spraying it in a drying chamber to create fine droplets, utilizing the surface tension of water to produce spherical, highly flowable granules. In a spray dryer, slurry is directly pumped into the drying chamber and atomized, allowing for the stable production of granules with an average size of around 50μm in a single process. This method stabilizes moisture, particle size, and bulk density, while also reducing dust generation. Additionally, it is possible to microencapsulate liquids using the inclusion effect of cyclodextrin, turning them into powder. [Features] - Spherical and highly flowable, making handling easy and reducing dust generation. - Short drying time allows for the drying of heat-sensitive raw materials. - By preparing a slurry with cyclodextrin (CD) encapsulating the liquid in water and drying it with a spray dryer (SD), powder can be produced in a single process. - Heat-sensitive liquids, such as fragrances, can retain their aromatic components through the inclusion effect of CD and the low-temperature drying of SD. *For more details, please refer to the PDF document or feel free to contact us.*

Applications/Examples of results
【Solving Such Problems】 ■ Slurry is squeezed into cakes using a filter press and then placed in a drying oven to remove water. The resulting sheet is mechanically crushed, but the process is lengthy, and there are complaints about the particle size and handling after crushing. ■ We want to add liquid compounds to powders or resins to give them functionality, but they mix poorly or do not mix at all. ■ We manufacture in-house, but the equipment is specialized, making it impossible to diversify products. ■ We can develop prototypes in small quantities, but we do not have equipment for mass production. *For more details, please refer to the PDF document or feel free to contact us.
