Contract manufacturing and contract testing of spray-dried granules *Microparticle granule manufacturing testing
A two-fluid nozzle capable of targeting D50 < 10μm, which was considered difficult to manufacture, has started operation! This will be used for application development in ceramics, other electronic materials, and battery materials!
"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. We have now commenced spray drying and fine particle granule manufacturing tests using a two-fluid nozzle. The two-fluid nozzle creates fine mist-like droplets by simultaneously spraying compressed air and the liquid to be dried. Like other spraying methods such as disk-type or pressurized nozzle types, it can produce spherical dried granules. A significant feature of the two-fluid nozzle is its ability to create fine granulating powders with an average particle diameter of less than 10 μm. *We also support tests and production using conventional disk spraying! 【Other Topics】 <Both our headquarters factory and Fukui factory are actively accepting spray drying tests!> In Osaka, we have three lab machines (one of which is compatible with organic solvents), and we have also installed one lab machine in Fukui, creating an environment where we can conduct tests more promptly. We will flexibly respond as a gateway to mass production and as the first step in research and development! *For more details, please download the materials or contact us.

Notice of Participation in the 8th Kansai Ceramics Japan Exhibition from May 17 (Wednesday) to May 19 (Friday), 2023.
Nichiwa Chemical will be exhibiting at the "8th Kansai Ceramics Japan" held at Intex Osaka. At our booth, we will introduce "contract manufacturing and testing of spray-dried granules." Invitation tickets can be obtained from the link below [Details & Application]. We sincerely look forward to your visit. 【About the Exhibited Products】 ■ Spray Drying with a Two-Fluid Nozzle – Microparticle Granule Manufacturing Test The two-fluid nozzle creates fine mist-like droplets by simultaneously spraying compressed air and the liquid to be dried. Similar to other spraying methods such as disc-type and pressurized nozzle types, it produces spherical dried granules. Recently, we have started contract testing in response to requests from customers involved in applications such as ceramics, electronic materials, battery materials, and cosmetics, who want to create spray-dried granules below 10 microns or around 5 microns, which cannot be achieved with disc spraying. ■ New Spray Dryer for Ceramics Installed at Fukui Factory! We have introduced the "FOC-20 (Okawara Kako Ki)" device with a maximum moisture evaporation capacity of 15 kg/h, and it has begun operation. We will continue to robustly advance small to medium quantities of various products to reliably meet the increasing demand!
