Abstract: A blender mechanism for applying a mixing action on containerized non-homogenized products. The blender mechanism includes a housing having a drive roller and an idler roller with the rollers being mounted in spaced apart parallel relationship with respect to each other and disposed in a substantially horizontal attitude. A drive assembly is coupled to the drive roller for rotational driving thereof and the drive assembly preferably includes a variable speed electric motor which is coupled through a gear train to the drive roller. The housing and idler roller are configured so that the idler roller can be moved to increase the spacing between the idler and drive rollers to accommodate larger sizes of containerized products. Also, an additional idler roller can be installed in parallel spaced relationship with the first idler roller so that a second containerized product to be mixed can be supported upon the spaced apart idler rollers.
