Electric linear motion enhances cheese processing and production.

Producing food that’s delicious, affordable and safe requires a lot from manufacturers. Process automation makes affordability possible and ensures consistently top-quality food. Safe food products and beverages are free of contamination, so the equipment used in food processing has to meet crucial requirements for cleanliness. That includes linear actuators.

Selecting a linear actuator for a food processing application requires careful consideration. A machine designer may look at hydraulic cylinders, pneumatic cylinders, rodless electromechanical actuators and electric rod actuators. 

Cleanliness is serious business in food processing.  The potential for contamination by microbes, chemicals and other foreign substances is real and always present. And food residue can be hard to eliminate. Keeping processing equipment clean makes good business sense. (Nobody wants their brand associated with foodborne illness.) Plus, the Food Safety Modernization Act (FSMA) makes it part of the law of the land. Food processors rely on their equipment to withstand the rigors of the processing environment. That’s especially true for hygienic linear actuators for food safety.

Machine designers who develop systems for harsh environments often need corrosion resistant components, including stainless steel linear actuators, to stand up to challenging environmental conditions. Corrosive agents, moisture and dust in manufacturing environments impact the performance and life of automationn components.  Dust and debris may enter housings causing wear. Moisture may short electrical connections.  Corrosive agents can eat away at housings, seals, fasteners and more. For confirmation that a component will stand up to environmental factors, we recommend the IP (International Protection or Ingress Protection) rating system.

Machine designers who serve the food processing industry face a huge opportunity.  Purchases of equipment are expected to grow 7% a year to around $70 billion by 2020.

Not surprisingly, consumer demand is fueling this growth, but equally important in the U.S. is the Food Safety Modernization Act or FSMA.  This legislation requires that food processors be proactive on food safety, that is, they must identify potential hazards and mitigate them.

A major result of the FSMA has been stepped up cleaning requirements and increased demand for hygienic equipment. That equipment needs washdown-ready components like electric rod actuators.
