The Munson Machinery sanitary rotary batch mini mixer model MX-5-S316L is on a mobile frame and can de-agglomerate and blend up to 5 cubic feet of dry bulk ingredients with or without liquid additions at multiple plant locations. The mixer achieves total uniformity in 2 to 3 minutes, regardless of disparities in the bulk density, particle size, flow characteristics or ratio of batch ingredients down to one part per million. Mixing flights within the rotating vessel turn, cut, fold and tumble material onto a rotating intensifier that reduces soft agglomerates into discrete particles. The mixer is equipped with a product inlet slide for ease of feeding from bags or boxes, and an inlet-mounted spray line that allows liquid additions to be spread over a wide bed of moving material in large or trace amounts for rapid, uniform distribution. Blended batches are discharged completely through a breech-lock plug gate with no segregation or residual waste. The unit can be rolled to a cleaning station and accessed through a hinged door on the vessel side wall for unobstructed wash down and visual inspection of all interior surfaces.
