Abstract

The invention apparatus comprises a mixing vessel closure having rotating mixing blades secured thereto. The mixing blades are driven through an axially engaged and disengaged direct coupling. The closure is mounted on a power base structure for rotation about an axis that is substantially transverse of the mixing blade axis. Additionally, the closure mounting includes a translational drive for linearly raising and lowering the closure at each of two positions about the transverse axis. A portable mixing vessel including a material charge is placed under the vessel closure. The closure is translated down to a sealed cover position over a vessel opening and secured to the vessel. The unitized assembly of the closure and vessel is translated away from a vessel supporting transport base and rotated to a inverted position. The unitized assembly is then translated down to engage a rotatory power transmission coupling. Rotatory power delivered to a fixed axis coupling element is thereby delivered to the mixing blades. At a conclusion of the mixing process, the procedure is reversed and the unitized assembly is rotated and translated back to the supporting transport base. The closure is then released from and translated away from the vessel containing the material mixture thereby leaving the vessel and the mixed material therein free of structural association with the power base.
