4th International Hosokawa Powder Technology Symposium
Held in Germany
On September 14th, 2023, the 4th International Hosokawa Powder Technology Symposium took place at the Dorint An
der Kongresshalle Hotel in Augsburg, Germany. The symposium was organized by the Hosokawa Powder TechnologyFoundation, in conjunction with KONA Europe e.V., the European / African Editorial Board of the academic journal
KONA, and was co-hosted and sponsored by Hosokawa Alpine AG.
The International Hosokawa Powder Technology Symposium was first held in 2014 at Hosokawa Alpine AG to celebrate
the Foundation’s 20th anniversary. Subsequent symposia took place in the United States in 2017 and China in 2019, making
this the fourth edition of the event.
The symposium began with a welcome speech by Dr. Kohei Hosokawa, Director of Hosokawa Powder Technology
Foundation and President of Hosokawa Micron Corporation. The theme of the symposium was “Sustainable Production ofFunctional Particles,” and it featured eight presentations highlighting collaborations between various companies, as well as
the overviews by the academic researchers.
In the presentations, hot topics such as the future prospects of cultured meat production using continuous production
facilities for cell culture media, dry and wet technology for efficient extraction of proteins from soybean, recycling technology and equipment for lithium-ion batteries, the relationship between processing techniques for rare earth materials
and the performance of neodymium magnets, and the introduction of new spheronization equipment for graphite, a criticalsecondary battery material, were discussed.
Additionally, Dr. Akira Watanabe, General Manager of the Technology Development Department of Hosokawa Micron
Corporation in Japan, shared insights into the differences in geopolitical and cultural perspectives between Japan andGermany, and the evolution of secondary battery material manufacturing equipment in Japan. At the end of the symposium,Dr. Fernández, President of Hosokawa Alpine AG, gave the closing remarks.
Participants came from various countries, including Germany, the host country, the Netherlands, and Lithuania. A welcome ceremony was held the day before the symposium. At the welcome ceremony, Dr. Steffen Sander, Secretary Generalof KONA Europe e.V. and head of the R&D center of Hosokawa Alpine AG, first explained about the company tour. Participants were then divided into small teams for a tour of the factory and the R&D center.
The guide explained that the company’s factory has production lines segmented by application, such as minerals, chemicals, and films, allowing the company to produce products of the high quality for each application. After the factory tour, thegroup was guided through the R&D center from the top floor to the first floor. The R&D center is equipped not only with lab
machines and small test machines, but also with test machines that are the same size as actual production facilities, whichis expected to reduce the risk of scaling up test machines when users set up actual production facilities. A separate testingmachine for pharmaceutical products is also available. With these well-equipped testing facilities, the company is able torespond to a variety of customer requests. After the company’s tour, the group was divided into two teams: one team went on
a tour of Augsburg, the famous walled city on the Romantic Road, while the other team toured the beer factory facilities. At
the end of the tour, all the teams gathered once again to enjoy delicious German beer in a beer hall adjacent to the brewery,and international exchange was promoted.
