Based on the feedback from the lab equipment, we have introduced a two-fluid nozzle for medium-scale machines to produce granulated powder with an average particle diameter of 5 to 20 μm in March 2024. Since the introduction of the two-fluid nozzle spraying mechanism for fine particle production testing in December 2022, we have received positive feedback from customers over the past year, and considering the requests for scale-up based on those results, we have also implemented the two-fluid nozzle spraying mechanism for medium-scale machines (Okawara OC-16 model). The installation was completed in March 2024, and after trial runs and internal testing, we plan to begin operations around May 2024. There is a strong demand for fine particles, but the places capable of conducting granulation tests and pilot production using spray dryers are extremely limited. We are committed to advancing the early establishment and operation of our facilities and technologies to contribute as a solution provider. *For more details, please refer to the PDF document or feel free to contact us.

We have started the operation of the lab equipment "CL-8 (manufactured by Okawara Kako Ki)" that can safely spray-dry organic solvent-based liquids under a nitrogen gas flow! The specifications of the device indicate an ethanol evaporation rate of 4 kg/h at a hot air temperature of 140°C. While there is a strong demand for organic solvents, there are extremely limited places where testing, the first step in production, can be conducted, leading to difficulties in development. We have received feedback regarding this issue through inquiries on our website and during exhibitions every year. To respond to this persistent need, we will begin operations in late January 2025. 【Solving these challenges and concerns】 ■ We want to safely dry raw materials that cannot be processed with water-based methods. ■ We lack spray-drying equipment and know-how, making testing and prototyping impossible. ■ We want to test what kind of powders can be produced with a spray dryer in small quantities. We are anticipating drying and granulating non-aqueous ceramics (such as aluminum nitride and silicon carbide), battery materials, resins, etc., but we will accept a wide range of materials and applications without imposing strict limitations. *For more details, please refer to the PDF document or feel free to contact us.
