Granulation

About us

In the Granulation technical group, excellent granulation technologies in various industrial fields are mainly introduced, and technical discussions are planned and carried out with the expectation that they can be applied to technological innovations in other fields. In particular, since granulation technology depends on human sensibility in many areas, we plan to introduce the “technology and operation methods” established based on the difficulties in actual operation, empirical methods and theoretical analysis.
We work with Mr. Ikeda (Kaken Pharmaceutical Co., Ltd.), Mr. Teruo Yoshida (Yoshida Consulting office), Mr. Isao Sekiguchi (Emeritus Professor at Chuo University) and Mr. Ichiro Yoshihara (Yoshihara Ichiro Consulting office) to do our group activities.

Current level of technology, trend and activities in future

Granulation operation is a unit operation aimed at improving bulk handling (segregation, consolidation, flow, dissolution, disintegration, transport, preservation, etc.) and adding new functionalities by controlling the morphology of powder materials. It is emphasized on the role of the product not only as a final form product but also as an intermediate form product. Intelligent and biomimetic multifunctional powders and granules with self-healing properties and biological functions are required, and diversification of powder materials into nanoparticles and soft matter raw materials such as polymers, liquid crystals, colloids, and biomolecules is expected. It is necessary to select the best granulator, binder and operating conditions for the granulation of these various materials, and simulation and IoT technologies are being introduced to optimize the control parameters as well as to achieve trouble-free operation. While the continuum populational balance is the mainstream, the introduction of discrete modeling and hybrid methods with other methods by adhesion modeling are making progress. On the other hand, the continuous process is accelerating with the progress of in situ measurement and soft sensor technology, and the introduction of AI, IoT and MI technology is expected to improve the granulation yield and optimize and combine the process.
