Granulation

About us

The Technical Group of Granulation introduces excellent granulation technology used in various industries. The group plans and implements technical sessions to make innovations in one field applicable to another field. The granulation technology depends on human sensibility and experience. Hence, the policy of this group is to introduce the technology and the operation technique established by analyzing difficulties in practical operation, empirical approach and theories.

The group asks the following persons for cooperation in the group management. Mr. Akiyoshi Takaoka (; Kaken Pharmaceutical Co., Ltd.), Mr. Teruo Yoshida (Yoshida Consulting Office), Mr. Isao Sekiguchi (Honorary Professor in Chuo University), Mr. Nobuo Arai (Powder technology Center.

Current level of technology, trend and activities in future

Granulation is a unit operation、the purpose of which is to improve powder handling (segregation, compaction, flow, resolution, disintegration, transport, maintenance etc ) and add functionality to powders by morphology control. What are needed in granulation are as follows.

  • Morphology design fitted to particle properties (size and shape of particles, inner and outer structure, composition, strength etc.)
  • Preparation of raw materials,
  • Selection of granulation method (growth, compaction and pattern of liquid droplet generation)
  • Selection of operation which is optimal to evaluation of granulated products
  • New technology.

Today nanoparticles are used as powder materials, and it is required to develop intelligent multifunctional particles using soft matters such as high molecular, liquid crystal, colloid, biomolecule etc. To meet these requirements, precise morphology control is important and in-line monitoring of the growth process of granulated powders is necessary. At present, non-invasive measurements making use of laser and NIR (Near InfraRed) are being developed. Materials and granulation methods are diverse. This group deals with the current level of granulation and future trend through discussion meetings which are held according to annual plan. Continuous operation is one of the most interested granulation technology. It is expected to visualize the growth mechanism in granulation by the use of on-time measuring technique and computer simulation such as DEM. The most important factors in the granulation characteristics are the choice and effects of additive which are determined empirically at the moment. This group will provide information of such factors in the discussion meeting, It is expected to accumulate information of powder process applying AI technology and to establish the technology which determines the choice of granulation operation and evaluates the properties of agglomerated particles.
