The Dairy Processing Industry Needs CinchSeal – This is Why

The Dairy Processing Industry Needs CinchSeal – This is Why

It’s no small thing that CinchSeal rotary shaft seals hold the “accepted” designation from the United States Department of Agriculture. This label alone separates CinchSeal from its competition and adds to an assurance that the seals will prevent contamination.

Nowhere more than in dairy processing is contamination control important. It can mean the difference not only between profit and loss for the processor but also, for consumers, sickness and health and even life and death.

The dairy processing industry is among the most heavily regulated, and there’s good reason.

As Thomas M. Sauer puts it in Food Safety Magazine, “Milk is an excellent growth medium for a variety of both pathogenic and non-pathogenic microorganisms.” In other words, the dairy processing industry needs a rotary seal that’s excellent at preventing cross-contamination.

So why do more and more dairy processors prefer CinchSeal rotary shaft seals? The short answer is “contamination prevention,” although other factors, such as certifications, innovative design and cost-effective performance, also play an important role.

Which Rotary Seal Best Prevents Cross-Contamination?

CinchSeal’s relationship with the USDA didn’t begin with the “accepted” designation. The USDA and CinchSeal worked together to develop high-performing rotary seals. The goal has always been to stop leakage and thus contamination before it starts.

This cooperative effort between CinchSeal and the USDA has resulted in rotary shaft seals that feature:

  • A U.S. Food and Drug Administration-approved silicone elastomer that is molded slightly smaller than the shaft to prevent material from leaking out and, at the same time, cause internal seal parts to turn with the shaft
  • Elastomer that, in contrast to stationary mechanical packing and lip seals, will not damage the shaft
  • Rotor Cups that are compressed with optimum load against stationary faces to seal leak paths
  • Purging with air or nitrogen to stop leakage into and out of the screw conveyor and to create a pressure differential that forms an air barrier that keeps product out of the seal.

Other kinds of seals simply do not have the performance qualifications of CinchSeal rotary seals. Take lip seals, for example.

The disadvantages of lip seals include:

  • Grabbing the rotating shaft using a smaller surface, which allows more access to contaminants
  • Limited ability to hold high pressure, again introducing the potential for leakage and contamination
  • Relatively short service life, so downtime and replacement costs tend to be higher
  • Inability to turn with the shaft, resulting in shaft damage
  • Lack of government certification for dairy processing

O-rings, braided packing, mechanical face seals and other alternatives share drawbacks found in lip seals. The score is somewhat lopsided in favor of CinchSeal rotary shaft seals.

What about cost-effectiveness?

If CinchSeal rotary seals are so much better, they must cost a lot more, right? Not really. In fact, innovative design has given these seals the edge in cost-effective performance. CinchSeal seals save money by:

  • Eliminating material loss, significantly cutting maintenance costs and preventing bearing failure and shaft damage
  • Making repair and maintenance easier
  • Keeping employees safer and minimizing area contamination
  • Standing up to the toughest environments

The ideal seal for the dairy processing industry has arrived!

In making a decision about which rotary seal to choose, it’s important to consider four things:

  • The dairy processing industry is especially vulnerable to cross-contamination which can result in enormous financial costs as well as danger to human life
  • A seal designed to remove or reconfigure the causes of leakage, damage and reduced service life will save downtime and costs in the long run
  • CinchSeal rotary shaft seals eliminate sources of leakage and contamination as well as maintenance and repair costs through innovative design
  • CinchSeal rotary seals are alone in holding the USDA’s “accepted” designation

Since 1994, CinchSeal has been a major manufacturer of 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
