Description

Application of Article 30, Paragraph 2 of the Patent Law 1. Title of Publication: Abstracts of Presentations at the 53rd Autumn Meeting of the Society of Chemical Engineers, Japan Publication Date: August 31, 2022 Publication Address: http://www3.scej.org/meeting/53f/index.html http://www3.scej.org/meeting/53f/prog/session_SY-54.html http://www3.scej.org/meeting/53f/abst/AC319.pdf This disclosure relates to a stirring and defoaming treatment system and a stirring and defoaming treatment method, which include a stirring and defoaming treatment apparatus that performs stirring and defoaming treatment on a container containing a material to be treated by revolving and rotating the material to be treated. When performing agitation and defoaming treatment on a container holding a material to be treated while it is revolving and rotating, it is preferable to be able to know the flow state of the material being treated. However, since the container holding the material is revolving and rotating, it is difficult to observe the flow state of the material inside it.
