Keeping clean is important, right? Well, in food and beverage processing and pharmaceuticals manufacturing keeping equipment clean is essential. Cross-contamination among batches causes problems, and food or beverage residue can grow harmful microorganisms. Many plants have clean in place (CIP) systems that deliver cleaning tailored to the needs of the facility including cleaning action (force, turbulence, direction), timing/duration (when, how often, how long), temperature, and type/strength of cleaning agent.
When you design equipment for these industries you need to keep cleanability in mind. Even components like electric linear actuators must stand up to cleaning procedures.
