Pathogenic bacteria can survive on stainless steel at room temperature for prolonged periods of time, meaning that a failure to properly sanitize surfaces in food and beverage applications can lead to harmful cross-contamination. Contaminated food products or packaging can lead to a wide range of health and safety concerns for both consumers and production workers. These risks can be largely mitigated with the implementation of regular sanitation protocols, typically using either conventional cleaning or steam cleaning.

Conventional cleaning methods rely on water in combination with strong chemicals to kill pathogens. These cleaning agents must be allowed enough time at a proper temperature in order to effectively sanitize surfaces, which can cause delays in production. Care must also be taken to avoid contaminating surfaces with the chemicals themselves, which are typically oxidizers that are toxic to humans. These chemicals may include:

  • Hypochlorites
  • Chlorine dioxide
  • Iodophors
  • Peroxyacetic acid
  • Quaternary ammonium compounds

Steam cleaning, on the other hand, offers a preferable alternative to conventional cleaning options. “Dry” steam cleaning mitigates many of the drawbacks of conventional cleaning while still providing effective sanitation. This method involves spraying surfaces with superheated jets of water which evaporate instantaneously. These bursts of dry steam kill even resistant microorganisms while producing minimal wastewater or residue.

Conventional Cleaning

Conventional wet cleaning methods have been in place for a long time because they offer some benefits and ultimately get the job done. However, these methods also have some notable concerns for food and beverage operations. The traits of conventional cleaning methods include:

  • Affordable

Steam cleaning requires costs for machinery, which can be a hurdle for facilities looking to incorporate it into their routines. More conventional cleaning methods simply require cheap, easy to find chemicals and cleaning tools.

  • Proven

Beyond cost, conventional cleaning methods are still effective against many pathogens and contaminants—even more so when used in combination with other techniques. However, conventional cleaning may not be fully effective against all hazardous materials. For instance, many pathogens have evolved biofilms which protect them from chemical penetration.

  • Limited

Traditional methods inconsistently agitate surfaces, making it more difficult and time-consuming to remove stubborn contaminants. In addition, the cleaning agents themselves may be hazardous. Conventional cleaning methods increase the risk of chemical cross-contamination, which can be harmful to workers and consumers.

Steam Cleaning

As a newer, more innovative method of cleaning and sterilization, dry steam cleaning was developed with the shortcomings of more traditional cleaning methods in mind. The benefits of dry steam cleaning include:

  • Effective

Steam cleaning mechanically agitates the surface being cleaned, which increases its ability to dislodge substances and bacteria that are otherwise difficult to remove. What’s more, the process involves extremely high temperatures that can penetrate the protective biofilms of microorganisms, killing pathogens that are resistant to cleaning chemicals and breaking their bond with the surface.

  • Environmentally friendly

The dry steam cleaning technique minimizes the environmental impact of sanitization. Compared to conventional cleaning, steam cleaning requires extremely minimal water consumption, introduces zero chemicals into the production line, and produces next to no harmful wastewater to process. This makes the practice especially attractive to companies that want to highlight their commitment to sustainable practices.

  • Safety

Reducing water use lowers the chance of water damage when sanitization occurs around electrical components or sensitive machinery. It also reduces the risk of fall injuries and contamination from water borne bacteria.

  • Speed

Without chemicals that need to rest on the surface to kill bacteria and other pathogens, dry steam cleaning offers a much faster solution that results in significantly less downtime due to cleaning. This also facilitates more efficient use of laborers.

Although a highly safe and efficient option, steam cleaning is not without its limitations. Because of the equipment involved, steam cleaning necessarily introduces a requirement for additional maintenance and a larger initial investment.

One of the major goals of food processors is the constant improvement of equipment hygiene to reduce the risk of potential product contamination. This means examining ways to control bacteria, spillage, dust and other potential contamination while maintaining a busy production schedule. A challenging problem considering that cleaning conveyor belts, both modular and flat solid types, can be labor-intensive task and in some cases uses many gallons of chemicals and alarming amounts of water.

A sanitized conveyor system helps food processors reach their number one goal, allowing the manufacturer to streamline production efficiencies. Let’s look at some of the ways to keep conveyor systems sanitized and contamination-free.

Best Conveyor Cleaning Methods for Efficiency and Safety

Several methods exist to help food processors maintain a properly cleaned conveyor belt system. Some of these include:

Use of Hand Cleaning

The majority of flat solid conveyor belts are hand washed by cleaning crews using strong chemicals. This process requires extended down times, intensive labor and is often highly wasteful. Workers and food products are put at risk from improper cleaning and handling chemicals. With proper training, plenty of time and the right chemicals, this method can be a suitable solution for some food processors. Ultimately hand cleaning lacks the consistency and reliability that an automated food processing production line needs to scale.

Use of Brushless Cleaners

One solution to avoid this is to leverage a brushless conveyor belt cleaner. These products can be mounted directly onto conveyor belts to clean and sanitize them with minimal downtime. The process utilizes dry steam vapor to break the bond between soil and surface on the conveyor belt, suspending the soil in dry vapor before it is vacuumed away from the conveyor surface. No chemicals are used and the water consumption is extremely low, being collected in a vacuum suitable for steam collection.

These systems can be attached to belts quickly and then easily removed after cleaning. The steam generator and vacuum are mounted on casters, enabling the setup to rotate between cleaning locations or even between facilities. Brushless cleaners leave conveyor belts clean, dry and potentially sanitized (ATP 0). From there, you are ready for your validation step and your next production run.

Choosing the Right Cleaning Belt Solution

The style and material of the belt — in addition to the thickness of the surface, the installation, and the load requirements — should all play a role in the purchasing decision for your specific use case.

Because sanitation is paramount to controlling harmful pathogens and bacteria, it’s also critical to select a conveyor cleaning system that meets to an acceptable validated standard of pathogenic bacteria – including listeria monocytogenes, e-coli, and salmonella. Such pathogens can quickly multiply and are difficult to detect, and even harder to clean.

The Eagle Series Automatic Brushless Belt Cleaner simplifies the process by utilizing an attachment that easily installs and removes within one minute, all with no moving parts on the cleaning head. 100% coverage of the belt removes the risk of human error in the cleaning and sanitizing process!

Studies show that heat is one of the most effective ways to sanitize equipment and manage bacteria. Food processing and production facilities are top candidates for using dry steam vapor cleaners as part of the sanitation process.
