Industrial Mixing Equipment
Sanitary Mixers
Ross serves the requirements of the Food, Cosmetic and Pharmaceutical industries, in virtually every industrialized country around the world. We have the experience and production capacity that no other manufacturer of specialty mixing and blending equipment can match.
In the USA alone, we operate five plants, an analytical laboratory and a vigorous R&D program. Overseas, Ross sanitary equipment is being built in our own factories in China and India, and manufactured under license in other countries. Typical applications include mixing, blending, particle size reduction, emulsification, homogenization, powder induction, vacuum processing and more.
Specifications that define a mixer built for a sanitary application reflect a combination of industry standards, and the mixing functions needed for that particular application. A sub-micron emulsion, for example, requires high-shear agitation, vacuum and usually a heat-transfer system. The size of the mixer is determined by the throughput required. To guard against batch-to-batch contamination, CIP and SIP capabilities are usually designed in, along with such devices as air-purged seals and custom designed discharge valves. To ensure a high degree of repeatability, and to document the production of every batch, we often add a control system with data-logging capability.

Sanitary mixing in multi-agitator systems
Multi-shaft mixers are versatile systems used in the production of food, beverage, pharmaceutical and medical products. This bulletin discusses a few equipment features commonly supplied on multi-shaft mixers intended for sanitary applications.
In order to safely transform raw materials into finished product, any mixing system must meet the minimum requirements for sanitary processing. These requirements do vary from one market, product category or application to another. Nonetheless, any plant complying with Good Manufacturing Practice (GMP) guidelines can consider the following general suggestions on mixer selection. In addition to these items, more specific requirements or custom mixer features must be discussed with your mixer supplier.
