MX-1-SSJ miniature rotary batch mixer

The MX-1-SSJ miniature rotary batch mixer achieves 100% batch uniformity in less than 3 min. The unit has Type 304 stainless steel contact surfaces, wide spacing of internal flights for easy access, continuous polished welds, and external moveable seals. Construction of exotic alloys as well as carbon steel, and configurations with clean-in-place (CIP) vessel-cleaning nozzles, are available. The mixer features an internal spray line for liquid additions, a discharge chute to direct the flow of exiting materials, and an insulated, jacketed mixing drum that can be piped to an oil, steam or chiller system. It can blend batches from 100% to 15% of its 1-ft3 capacity, and can distribute ingredients with 100% uniformity regardless of disparities in the bulk densities, particle sizes or flow characteristics of batch ingredients. Its mixing process moves material from the sides of the vessel and folds it back toward the horizontal axis, which effects both a diagonal and a vertical tumbling motion. Lifters continuously cut out portions of the material and fold them back into the main body of the batch, resulting in rapid particle distribution without degradation. This process causes most of the particles to contact the jacketed vessel’s heated or chilled walls, maximizing heat-transfer efficiency.
