Description

  The present invention relates to a revolution / spinning stirrer using a combined centrifugal force by rotating and rotating a stirring vessel.

  Conventionally, there has been known a revolving / spinning agitator that performs mixing agitation and defoaming by revolving a container holder containing a stirring container by a planetary gear or a transmission belt on its revolving track while revolving. It is presented in Japanese Patent Application Laid-Open No. 61-290946 and Japanese Patent Application Laid-Open No. 10-43567.

  The revolution / spinning stirrer is used for a mixture that is difficult to mix with a normal stirrer or a mixture that is difficult to defoam, because it has excellent stirring ability due to the combined centrifugal force generated by revolution and rotation in a stirring vessel.

  By the way, in the agitator, the mixing of the stirring material in the stirring container may be difficult to stir because the viscosity is too high at room temperature, or separation or decomposition may occur due to temperature increase due to frictional heat generated by stirring. However, controlling the temperature of the stirring material in the stirring vessel is an important issue, but it is extremely difficult to attach a heating device or cooling device directly to a stirring vessel that rotates at high speed from a structural and safety standpoint. Conventionally, for example, as disclosed in Japanese Patent Publication No. 2005-25717, etc., which controls the atmosphere in a case (chamber) covering the entire apparatus, and presented in Japanese Patent Application Laid-Open No. 2007-136868, etc. As shown in Japanese Patent Application Laid-Open No. 2006-305512, a container containing a refrigerating agent that has been cooled separately with a double stirring vessel holder Such as those that control the speed of the rolling and rotation are known.

  However, when controlling the atmospheric temperature in the case, it takes time to set the temperature to a predetermined temperature and not only wastes energy, but also does not directly control the temperature of the stirring vessel and is difficult to respond quickly. . In addition, in the case of storing a cooling agent or the like with a double stirring vessel holder, it takes time and effort and cannot be controlled to a desired temperature because a separately cooled cooling agent or the like is mounted. Furthermore, in the case of changing the rotation of revolution or rotation, it is possible to cope with the temperature rise due to friction during mixing, but on the other hand, it leads to a decrease in mixing capacity and is not efficient. There is a problem.

  In addition, the conventional revolution / spinning stirrer is for stirring and mixing by storing the mixture in the stirring vessel and then stirring and mixing. For example, when the fluid and the powder cake are mixed in the stirring vessel at one time, There is also a problem that secondary aggregation is likely to occur.
