A sanitary rotary mixer that is washdown-rated

| By Mary Page Bailey and Gerald Ondrey

The Model MX-5-S316L sanitary rotary-batch mini-mixer (photo) can de-agglomerate and blend up to 5 ft3 of dry bulk ingredients with or without liquid additions at multiple plant locations. The mixer achieves total uniformity in 2 to 3 min, regardless of disparities in the bulk density, particle size, flow characteristics or ratio of batch ingredients down to one part per million (ppm). For dry materials, the mixer is equally efficient down to 15% of rated capacity, satisfying varied production requirements, while allowing for small-scale testing prior to blending at full capacity or scaling up to high-capacity rotary-batch mixers. 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 breach-lock plug gate with no segregation or residual waste. The unit’s gears are washdown-rated and are adjusted by variable-frequency controls housed in a NEMA 4X (IP 66) stainless-steel washdown enclosure. — Munson Machinery Co., Utica, N.Y.
