Abstract

LR500, an easily constructed new type of impeller, was developed for mixing highly viscous liquid, and its mixing performance was evaluated. LR500 showed stable operating characteristics with the same non-dimensional mixing time as a helical ribbon impeller and was able to mix highly viscous liquid of various liquid depths. In contrast, the helical ribbon impeller was not able to mix highly viscous liquid when the liquid depth was set at the position of the support bar, because an isolated, doughnut-shaped mixing region was generated in the vessel.
