ABSTRACT:
A dual-spindle blender includes a container having two intersecting lobes forming a figure-eight cross section with a cutter blade assembly disposed centered in each lobe. The bottom of one of the lobes is lower than that of the other lobe so that, when small quantities of material are treated, it preferentially falls into the lower bottom to produce a deeper pool which can be operated on by the associated cutter blade assembly. In one embodiment of the invention, the cutter blade assemblies are at the same height and are spaced with their planes of rotation non-intersecting. In another embodiment of the invention, the cutter blade assemblies are displaced in height, whereby the blades are offset from each other. In this embodiment the offset of the blade heights optionally permits their planes of rotation to intersect without suffering blade strikes.
