Charlotte Colloid Mills for Mayonnaise, Salad Dressings, and Sauces

Our “SD” Series of Charlotte Colloid Mills are fabricated from all type 316 stainless steel in the process area for sanitary applications. Product processing chambers are fully jacketed for optional heating or cooling. All mills may process materials up to 400°F and withstand product throughput pressures up to 150 PSI (100 PSI on the SD-2.) Products to be processed must be in a pumpable slurry. All units are non-aerating, high shear, in-line equipment and can be fully calibrated in increments of .001”. Average micron particle size that can be achieved is usually between 3-5 microns. The horizontal design of the Charlottes lends itself to inline installation. Together, with its “user-friendly” assembly for easy maintenance and non-aerating production chamber, the Charlotte Colloid Mills may be used for either batch or continuous processing. The unique hydraulic shear and centrifugal action production chamber allows the Charlottes to process the most viscous products. The Charlotte can be cleaned in place.
