150-Gallon Double Planetary Mixers

Charles Ross & Son Company recently developed two specialty customized 150-gallon double planetary mixers (Model DPM-150) with patented high viscosity blades. Features include interchangeable jacketed vessels, electrohydraulic lift, recipe controls with data logger, and an all stainless-steel sanitary design. The mixers consist of two identical blades that move in a planetary motion, rotating on their own axes as they orbit a common axis. In 36 revolutions around the vessel, the two blades pass through every point in the product zone, physically contacting the entire batch. When mixing high viscosity products upwards of two million centipoise, the blades impart a kneading action to the batch, smoothing out its consistency and breaking up any agglomerates.
