ORGANIZATION AND ITS GOAL
Technical Group of Crystallization, the Association of Powder Process Industry
and Engineering Japan suggests the practical industrial crystallization
technology to be shared among all different groups, challenging to improve
the technology systematically derived from the design theories of crystallizers.
The Technical group also aims fostering of young technical experts and
researchers, offering active communications among them both domestically
Being organized by seven member companies, the Technical group plans conferences
3-4 times a year, providing lectures, workshops and panel discussions as

OUTLINE OF THE TECHNICAL GROUP
Technical Group of Crystallization was established in 1997 under
the leadership of emeritus professor Ken Toyokura as the 20th
technical group of the Association of Powder Process Industry
and Engineering Japan, and started its activities in 1998.
technical group primarily
focuses on promoting the understanding of industrial crystallization
required for new-generation technology and solving common problems
in industrial crystallization practice among related companies.
Active discussions are also suggested by the Technical Group
upon the application of the understanding for new crystallizer
and operational concept.
Since the Technical Group was established in 1997, it has been
promoting international exchange of industrial crystallization
many successful lectures and workshops.
2002.11.13～14 （Nippon Convention Center (Makuhari Messe) International Conference Hall）
International Symposium on Industrial Crystallization Inspiring Powder Technology, 2002
As the first international symposium delivered by the Panel, the symposium aims more active international collaboration for the future, offering an oral session (simultaneous interpretation provided), a digital poster session and a round table style panel discussion.
2002.07.27 （Bunkyo Civic Center Sky Hall）
SKY SEMINAR “BASIC KNOWLEGDE OF CRYSTALLIZERS AND SCALE-UP”
Organized as a pre-international symposium, a panel discussion was offered, employing the Q&A style. The panelists introduced their ideas and approaches, answering the questions from attendees. This was a very successful seminar especially as a preparation for the international symposium.
2002.05.24 （Memorial Hall of Nippon Chemical Industrial Co., LTD.）
“Crystallization Technical Development”
Mr. Steve Sanders（OLI Systems, Inc.）
The latest research and developments in crystallization simulation in the United States were
presented by Mr. Sanders.
“Design Theories of Crystallization Process and Equipment: Application and Practice”
This book well summarizes the outcome of the lectures and workshops organized by the Panel in the past, aiming to provide practical information and guidance of industrial crystallization for young experts.
2001.07.27 （Kameido Cultural Center ）
“Outline of CRYSOPT and the latest development of crystallization in Europe”
Prof. Joachim Ulrich (Martin-Luther-Universitat Halle-Wittenberg)
