Publication number: 20230049238Abstract: An agitating/defoaming apparatus adjusts a rotation speed and, even with respect to a material high in viscosity, prevents or reduces an increase in temperature of the material during agitating/defoaming. The agitating/defoaming apparatus includes a plurality of container holders, each holding a container. A revolution member supports each container holder so as to be rotatable, is provided in such a way as to be rotatable on a first rotational shaft, and causes each container holder to revolve around the first rotational shaft. A first drive rotationally drives the revolution member. A control unit performs drive control. An annular outer ring is arranged to surround the container holders in such a way as to be in abutting contact with an outer circumferential portion of each container holder. An outer ring rotation mechanism rotates the outer ring with a central axis of the outer ring set coincident with that of the revolution member.Type: ApplicationFiled: December 8, 2020Publication date: February 16, 2023Applicant: MITSUBOSHI KOGYO CO., LTD.Inventor: Yoshiaki KANEKO
