4 Ways Using CinchSeal Improves Cheese Processing

The global cheese ingredients market is projected to reach $102.14 billion by 2022. The demand for cheese, a key ingredient in many cuisines, is rising globally – with production of cheese spreads, shredded cheese, cheese powder, and all kinds of melted and liquid cheese growing each year.

If you’re in the business of processing cheese, you probably know how costly it can be to lose time and valuable product, from cream to mozzarella, due to shaft sealing problems. Faulty seals can lead to unfortunate situations like:

  • Unscheduled downtime
  • Gearbox failure
  • Product contamination
  • Plant sanitation
  • Shaft repairs

CinchSeal rotary shaft seals are proven to virtually eliminate all of these issues.

With older technologies like mechanical packing and lip seals, these expensive problems are all too common. By contrast, CinchSeal rotary shaft seals are designed to save time, product, and money when sealing industrial conveying and mixing equipment such as:

  • Screw Conveyors
  • Cheese Cookers
  • Mixers
  • Blenders
  • Rotary Air Locks
  • Augers

Why CinchSeal shaft seals are the answer for cheese processing

For the food processing industry in particular, CinchSeal rotary shaft seals are highly attractive for offering advantages like:

  • Safety certification
  • Proven contamination prevention
  • Superior design
  • Cost-effectiveness

Safety certification

Nothing is more important in food processing than safety. If safety is compromised, both manufacturers and consumers suffer. That’s why the industry is so heavily regulated. Adhering to good safety practices not only prevents threats to human life and health but also expensive downtime, product recalls, and litigation.

Because of these important concerns, CinchSeal consults with the U.S. Department of Agriculture on the design of rotary shaft seals made for food processing applications. They are USDA-certified for poultry and dairy, and the USDA’s “accepted” designation assures they will not cause contamination.

Contamination prevention

How do CinchSeal shaft seals prevent contamination? By preventing leakage. CinchSeal rotary seals offer a number of contamination-fighting features, including:

  • Leak preventing, FDA-approved silicone elastomer molded slightly smaller than the shaft. The elastomer creates an interference fit to prevent material from leaking out.
  • Elastomer that spins with the shaft, stopping shaft damage that can result with stationary seals like mechanical packing and lip seals
  • Rotor cups compressed with optimum load against stationary faces when the elastomer turns with the shaft. The rotors seal potential pathways for leaks.
  • Air purging that performs three vital functions:
    • Creating higher pressure in the seal chamber to form a natural air barrier to keep product out of the seal
    • Reducing heat caused by friction
    • Pushing the rotating faces outward against the stationary faces creating a tight seal

CinchSeal rotary shaft seals are designed to offer the highest level of protection against contamination and, at the same time, remain highly cost-effective.

Innovative design

The design innovations that make CinchSeal seals ideal for cheese- and other food-processing applications don’t stop with elastomers and air purging. They extend well beyond them to include:

  • Providing a larger shaft/seal interface surface than is possible with lip seals, so the opportunity for leakage and contamination is significantly lowered
  • Creating boot-mounted rotor cups so the rotary assembly is able to float with the shaft and accommodate a 1/4” misalignment that often occurs with bulk-handling equipment
  • Developing a self-cleaning and self-lubricating design that allows seals to operate dry
  • Making repairs possible without unbolting the housing by splitting internal parts
  • Providing repair kits to replace just an elastomer and rotor cups or stator plates; the durable housing stays like-new

Together, these innovations give CinchSeal rotary seals the ability to perform more cost-effectively than other seals on the market.

Cost-effective performance

How do CinchSeal’s innovative designs improve cost-effectiveness? To offer a few examples, they:

  • Stop product loss
  • Reduce maintenance significantly
  • Prevent shaft and bearing damage
  • Stand up to the food industry’s most challenging environments
  • Keep employees safe
  • Provide easy maintenance and repair

A rise in dairy demand

As a key ingredient, the demand for cheese is rising globally from the production of cheese spreads, cheese foods, pasteurized processed cheese, and more.
Depending on the type of cheese, the process of manufacturing it will vary. Here are 4 processes that are in use: 

Processed Cheese

Processed cheese consists of 51% of natural cheese, along with emulsifiers, whey, additives, and preservatives. With the demand for cheese increasing, processed cheese is becoming more and more cost-effective to produce. Processed cheese is further sub-segmented as restricted-melt, standard-melt, and quick melt.


Restricted-melt cheese is formulated to soften at higher temperatures without melting and changing its shape. Restricted-melt cheese is used in applications where it is important to limit the flow of cheese to avoid leakage. It is mainly used in baked or fried foods, sausages, cheese bratwurst, and microwaveable sandwiches, among others.


Standard-melt cheese melts at a bit higher temperature than quick-melt cheese. It can replace natural cheese in applications such as slicing, cutting, and shredding. This cheese can be used with bread, meat and other food applications to enhance the taste of the product.


Quick-melt cheese melts easily which makes it suitable for general product applications. This cheese is usually used in dips and sauces while some quick-melt cheeses are used in food products such as pizzas and burgers for flavor enhancement.


CinchSeal’s contribution to cheese processing and the food industry as a whole boils down to two points:

  • The industry needs innovative designs that improve on and replace outdated versions such as mechanical packing and lip seals to fight contamination, leakage and costly repairs at a reasonable price.
  • Cost-effectiveness goes far beyond the initial price of the seal. You have to consider the cost of repair, replacement and maintenance.
