The case for electric rod actuators in food processing applications

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.

Electric cylinders speed up food processing operation

From food processing plants to machine shops, there’s a constant drive for greater efficiency, faster turnaround and less downtime. Everyone is involved in the effort, from design engineers who develop equipment to plant engineers who manage processes. In food processing operations, the need for speed translates into things like faster operation, easier cleaning, greater accuracy and less maintenance.  Electric linear actuators and electric cylinders used in these plants need to meet specific standards.

Keeping it clean: hygienic linear actuators for food safety

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.

What to consider: electric actuators for food and beverage processing

Keeping things clean is a top concern in food and beverage processing operations because food safety is crucial.  The Food Safety Modernization Act (FSMA), with its emphasis on preventing foodborne illness, puts even more pressure on food producers. Machine designers who serve this industry need to incorporate components that meet the industry’s demands. When it comes to electric linear actuators, there are several things a design engineer needs to consider, especially if the machine will be subjected to periodic washdowns.

Stainless steel linear actuators stand up to corrosion, tough conditions

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.

Electric cylinders essential to advanced conveyor system [Case Study]

Conveying systems are common in manufacturing. They can be straight-forward systems that take packages from point A to point B or complex ones for sorting and diverting.  Systems used in food processing also must handle washdowns, a common practice in the industry.

As critical components, linear actuators must withstand the challenges of the application including environmental ones.  Pneumatic cylinders have been used extensively in conveying. However, electric cylinder use is growing, fueled by demand for programmability and better accuracy.

Machine design, FSMA, and electric rod actuators

What a machine designer needs to know

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.

Machine design, clean in place (CIP) and linear actuators

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.
