Sealing Solutions For The Food And Beverage Industry

Category: Food and Beverage

The food and beverage industry has experienced dramatic change over recent years. Consumer expectations for ever-increasing variety is a key driving force, as is the stringency of multiple compliance legislations. At the heart of this vast industry, reliability of the smallest of components plays a crucial role – that of the humble seal.

Sealing Integrity: The Challenge

From extremes of temperature variations to withstanding the use of aggressive cleaning fluids, the integrity of every seal within a production system must be without question. Failure of seals lead to catastrophic outcomes: product recalls, poor publicity, stoppage of plant and equipment and in worst-case scenarios, public health enquiries as to how the incident occurred.

The complexity of a sealing system requires engineers to utilise ever-advancing technology to bring upgraded solutions that conform to the strictest of regulatory standards. These include:

  • Fluorocarbon plastics
  • Elastomers
  • Drinking water seals

The key to the ultimate sealing solution is to determine the environment and the variables under which the seal/s must perform.

Seal Solutions: A Dynamic Landscape

The food and beverage industry comprises a vast array of processes. From beer to chocolate, ice cream to convenience foods, the stresses a seal undergoes is determined by the type of production being carried out.

Selecting the right profile and material for sealing equipment will be based on:

  • The process, it will be exposed to (what is being produced)
  • The environment and conditions it will work under (temperatures, lubrication, cleaning fluids, speeds, pressures and operation)
  • The length of time it’s expected to last

Of course, the material and seal must also conform to international, national and regional health and safety requirements.

The key takeaway is that the right sealing solution begins with talking to determining the engineering specifications is only the start. Variables must also be accounted for, both the seen and unforeseen.

This will allow for the appropriate selection of the initial and, further down the line, the replacement seals that guarantee integrity and longevity.

The Effect of Industrial Lubricants and Maintenance

Lubrication is an essential element in food processing equipment. The type used has a direct bearing on the lifespan of seals, making it imperative to use the highest grades to prevent premature wear.

Oils and lubricants used within food and beverage applications should (dependent on the individual use):

  • Be free from ketones, aromatics and chlorinated solvents
  • Contain no heavy metals
  • Be able to work effectively in extremes of temperature
  • Be water and chemical resistant

Chesterton’s high performance greases offer extended bearing life and reliability even under the harshest conditions of load, temperature, water, and corrosion.

When it comes to other maintenance speciality products, such as PTFE packing/sealant, tape and flexible gasketing material, it’s also crucial to ensure the right product is used and is of the highest quality.

For instance, sealant tape should be adjustable, high-density, mouldable and tear-resistant. It should also have the ability to be used with virtually all chemicals and be proven effective in extremes of temperature. PTFE packing should be non-reactive to chemicals, work in a wide pH and temperature range, and able to withstand extensive pressures.

The ever-increasing demands on the food and beverage industry, including specialised requirements and variable operating cycles, makes seal selection ever-more crucial. Time spent making the right sealing solution choices directly impacts production, output and baseline profits.
