What Does It Mean for Rotary Shaft Seals to Be USDA Certified?

What Does It Mean for Rotary Shaft Seals to Be USDA Certified?

Being USDA certified isn’t for every grower, food processor or commercial kitchen. That said, it’s becoming more and more expected by the people who buy products from these organizations, so it might be something to look into.

Just what does being certified by the United States Department of Agriculture actually mean? For one thing, it demonstrates that the outfits being certified are willing to jump through a few hoops once they’ve decided it’s worth the trouble.

The goal of going through the USDA certification process is to earn the right to use the USDA certified seal and display the certified USDA logo on products. In this way, trying to meet  grower, food processor and USDA certified kitchen requirements will visibly set businesses apart from the competition.

How to Get USDA Certified

Achieving certification is definitely a process. The steps include:

  • Adopting safe practices
  • Writing up a plan for sanitary operations
  • Selecting a USDA-accredited certifying agent
  • Submitting an application and paying fees
  • Going through an on-site inspection
  • Sitting your thumbs for a few weeks or months while the certifying agent reviews the application and the inspector’s report
  • And, at long last, receiving certification

It sounds like a lot because it is. And, to maintain the integrity of the USDA certified seal, it should be.

The process: a few helpful details

To make things seem at least a bit simpler, the road to USDA certification can be broken down into five major segments:

  1. Put together a plan. This had better be good. The “sanitary system plan” is the basis on which a successful certification process is built. It tells the inspector and the certifying agent how the operation will meet applicable regulations. It includes every aspect of the operation and how it keeps unsafe substances prohibited by the USDA from getting in.
  2. Put the plan into action. But first, have a certifying agent review the plan. This can save a lot of time and trouble. You can find a certifying agent through the USDA. There’s a list on the website.
  3. Get inspected. Once the operation is running to your satisfaction, request an inspection. It won’t be a quick look-over. The inspector will give your operation the complete physical, looking in places you might not know you have places. It’s smart to make sure you’ve followed your plan to the last dotted “i” and crossed “t.”
  4. Get the inspection inspected. This puts things squarely in the certifying agent’s corner. The inspector presents the report to the agent and the agent decides whether it meets the requirements of the plan and all the pertinent regulations. A fine-toothed comb might be involved.
  5. Position thumbs and have a seat. If you’ve complied with your plan and all the regulations, you’ll be certified. But you’re not off the hook. You can expect inspections at least once a year.

Ensuring a safe, sanitary operation

It should be clear by now that one very important factor in establishing a safe and sanitary business is the choice of equipment. So it’s a good idea to ask your equipment supplier about how it can help you meet the requirements. For example, you should talk to manufacturers such as CinchSeal, makers of rotary shaft seals, to learn how our USDA-certified dairy equipment protects your products from contamination.

USDA Dairy Seals

Certified USDA Dairy Seals

CinchSeal has certifications for USDA Dairy and USDA Meat and Poultry. Despite both being USDA certifications, they each have their own requirements. We’ll keep the focus on USDA Dairy certification.

Typically, dairy sealing applications pose many challenging requirements related to hygiene and reliable sealing.

From a mechanical sealing designer’s point of view, the implementation of an effective hygienic seal begins with the right choice of sealing material and the specific design which is easy to clean reliably.

An effective dairy industry sealing material needs to demonstrate a broad chemical compatibility profile, compatible with virtually all process media and able to withstand cleaning regimes and sterilization practices including solvents, steams and amines.

Our USDA Dairy Certified industrial seals demonstrate:

  • Reduced process contamination
  • Reduced equipment downtime
  • Increased seal lifetime
  • Extended equipment planned maintenance interval

In general the use of shaft contact seals in dairy applications can further complicate matters, whereby the seal running surface is in contact with, and runs against the shaft, causing friction. The friction generated has several potentially detrimental effects, including:

  • The seal can wear down the shaft, leading to shaft damage requiring expensive repair or replacement
  • The seal contact face experiences wear, leading to seal failure and replacement
  • Worn sealing materials can migrate into the process media, resulting in process contamination
  • The frictional heat generated can damage the process media

Unlike packing or lip seals the Cinchseal’s industrial seal solutions can handle large shaft run-outs as the seal internals rotate along with the shaft. This allows for better and consistent sealing thereby eliminating food/product leakages common to packing and lip seals that are not tolerant to dynamic shaft run-outs.

Also, as the seal internals of the Cinchseal rotate along with the shaft the possibility of food contaminants scratching, damaging or wearing the shaft are minimal. All of this provides a more sanitary and repeatable seal assembly.

Simplify the seal repair and replacement process by choosing a seal design requiring no major machine disassembly, saving time and resources and getting your process line operational much more quickly.

Takeaway

Since 1994, CinchSeal has been a major manufacturer or rotary shaft seals for screw conveyors, ribbon blenders and all kinds of bulk handling equipment. CinchSeal products serve as replacements and major upgrades that make the need for machine replacement less likely.
