The Important Thing Most People Get Wrong

When comparing modular belt cleaning systems, many people assume that more automation means better cleaning performance.

In reality, this is usually not true.

Assuming the same steam power is being used, all three approaches are capable of achieving the same cleaning result.

The difference is not the cleaning power.

The difference is how that cleaning power is applied and how much operator involvement is required.

Fully Automated Modular Belt Cleaning

Jet System

 

The Jet System is our most popular modular belt cleaning system worldwide.

The principle is simple.

The operator creates a cleaning program, typically in less than 30 seconds, and the system automatically cleans conveyor belts of virtually any width and any length.

The belt is divided into strips known as sectors. The cleaning head then automatically traverses across the belt, cleaning one sector at a time until the entire belt has been cleaned.

Unlike a human operator, the system:

  • Does not get tired
  • Does not miss areas
  • Delivers the same cleaning pattern every time
  • Can operate continuously for hours

This makes it particularly well suited to:

  • Spiral coolers
  • Long transport conveyors
  • Oven discharge conveyors
  • Large modular belt systems

The system can store up to 20 cleaning programs, allowing the same unit to be moved between multiple conveyors throughout the factory.

In practice, the operator’s involvement is often limited to:

  • Moving the cleaning head to the next conveyor
  • Refilling the steam generator if continuous water supply is not connected

For factories with long modular belts, it is difficult to find a more labour-efficient solution.

Semi-Automated Modular Belt Cleaning

Static Spinner

 

The Static Spinner sits between manual and fully automated cleaning.

A rotating steam manifold remains fixed in position and continuously cleans a strip of conveyor belt equal to the diameter of the spinner.

Common spinner sizes include:

  • 110 mm
  • 180 mm
  • 240 mm

Multiple spinners can also be installed to clean multiple strips simultaneously.

As a rough guide, each spinner requires approximately 18 kW of steam power.

Once the conveyor has completed a full revolution through the cleaning zone, the operator manually repositions the spinner to the next location.

The repositioning process typically takes only a few seconds.

For example, a 500 mm wide conveyor that takes 30 minutes to complete a full circuit may only require two manual movements during the entire cleaning process.

For narrow and medium-width conveyors, this can provide an excellent balance between labour reduction and simplicity.

As belt widths increase, however, the number of manual repositioning operations also increases.

This is where the Jet System begins to offer a significant advantage.

Because the Jet System automatically traverses across the conveyor and uses an oscillating cleaning manifold, it can cover larger areas in fewer passes and often reduce total cleaning time.

Manual Modular Belt Cleaning

Handheld Spinner

The Handheld Spinner places the rotating steam manifold directly in the hands of the operator.

While it is the least automated solution, it remains one of the most useful tools available for modular belt cleaning.

It is particularly effective for:

  • Very narrow conveyors
  • Short modular belt sections
  • Transfer conveyors
  • Packing line conveyors
  • General factory cleaning

Many food factories contain dozens of short conveyor sections where setting up automated equipment simply does not make economic sense.

In these situations, operators can move rapidly from conveyor to conveyor, often cleaning each belt in as little as one to three minutes.

This is where the Handheld Spinner excels. In many factories, operators can clean multiple short conveyors in the time it would take to set up an automated cleaning system.

It is also useful for cleaning:

  • Checker plate
  • Ladder belts
  • Difficult-to-access areas
  • General production equipment

For many factories, the Handheld Spinner becomes the tool that fills the gaps left by more automated systems.

Typical Industry Configurations

Over time, certain patterns emerge.

Bakeries

Typical solution:

  • Jet System
  • Handheld Spinner

Bakeries often contain:

  • Spiral coolers
  • Long oven belts
  • Long modular conveyors

These applications suit the Jet System perfectly.

However, bakeries also contain numerous shorter conveyors feeding packaging lines and secondary processes.

These are often cleaned most efficiently using a Handheld Spinner.

Beverage and Drinks Factories

Typical solution:

  • Static Spinner
  • Handheld Spinner

Unlike bakeries, beverage facilities often have large numbers of narrow and medium-width modular conveyors.

Wide modular belts are relatively uncommon.

As a result, many beverage facilities favour a combination of Static Spinners for routine cleaning and Handheld Spinners for flexibility and detailed cleaning.

Which Cleans Best?

The honest answer is:

All three.

Assuming the same steam power and appropriate cleaning speeds, the cleaning result is often remarkably similar.

The real differences are:

  • Labour requirement
  • Cleaning time
  • Repeatability
  • Operator involvement
  • Convenience

The best system is therefore not necessarily the most automated.

It is the system that matches the conveyor layout and operational requirements of the factory.

Conclusion

There is no universal solution for modular belt cleaning.

The Jet System is ideal for long conveyors where labour reduction and automation are priorities.

The Static Spinner provides an excellent middle ground for medium-width belts requiring only occasional operator intervention.

The Handheld Spinner remains unmatched for short conveyors, narrow belts and general factory cleaning.

In practice, the most successful installations often combine one level of automation with a Handheld Spinner to cover the remaining cleaning tasks throughout the factory.

 

Frequently Asked Questions

Does automated modular belt cleaning clean better than manual cleaning?

Not necessarily. Assuming the same steam power and cleaning methodology are used, manual, semi-automated and fully automated systems can all achieve excellent cleaning results. The main advantages of automation are consistency, repeatability and reduced labour requirements. Automated systems do not get tired, do not miss areas and deliver the same cleaning pattern every time.

How much operator involvement does a Jet System require?

Very little. Typical setup takes around 2-3 minutes and involves positioning the system on the conveyor, adjusting for belt width and height, loading a saved cleaning program and pressing start. The only ongoing intervention is moving the system to the next conveyor and periodically refilling the steam generator if a continuous water supply is not connected.

What is the difference between a Static Spinner and a Jet System?

A Static Spinner remains fixed in one position while a section of conveyor passes through the cleaning zone. Once the belt has completed a full cycle, the operator manually moves the spinner to the next section of belt. A Jet System performs this movement automatically. It also oscillates the cleaning manifold, increasing coverage per pass and reducing the total number of cleaning passes required.

When is a Handheld Spinner the best choice?

Handheld Spinners are ideal for factories with numerous short, narrow conveyor sections where setting up an automated system is not practical or economical. They are also highly effective for general factory cleaning and for cleaning equipment that cannot easily be accessed by automated systems.

Can a Handheld Spinner clean as effectively as an automated system?

Yes. The cleaning capability is comparable when the same steam power is used. The difference is that automated systems provide greater consistency and repeatability while reducing operator fatigue.

How many conveyor belts can a Jet System clean?

There is effectively no limit. The system can be moved between conveyors and store multiple cleaning programs. As a general rule, if the system is sized for the widest belt in the factory, it can also clean any narrower belts provided sufficient mounting space is available.

How long does it take to set up a Jet System?

Typically around 2-3 minutes. Most users can position the frame, adjust for belt dimensions, load a saved program and begin cleaning within a few minutes.

What steam generator is normally required for modular belt cleaning?

Most modular belt cleaning applications are performed using an 18 kW steam generator such as the KHD-32. Larger systems may require additional steam power depending on belt width and the number of cleaning heads being used.

Can multiple Static Spinners or Jet System cleaning heads be used on the same conveyor?

Yes. Both systems can support multiple cleaning heads. As a general guide, approximately 18 kW of steam power should be available for each spinner to maintain cleaning performance.

What types of modular conveyor belts can be cleaned?

Most modular plastic and open mesh conveyor belts can be cleaned effectively using steam cleaning systems. One potential complication is a solid belt bed beneath the conveyor. In these cases, debris cannot easily pass through the belt and may collect beneath the cleaning area, potentially increasing the risk of recontamination on the return side of the conveyor.

Which modular belt cleaning system is best for beverage and drinks factories?

Many beverage facilities favour a combination of Static Spinners and Handheld Spinners. These factories often contain large numbers of narrow and medium-width modular conveyors where fully automated systems are not always necessary.

Which modular belt cleaning system is best for bakeries?

Bakeries often benefit from a combination of Jet Systems and Handheld Spinners. The Jet System is well suited to spiral coolers, oven discharge conveyors and long transport belts, while the Handheld Spinner is ideal for shorter conveyors and packaging areas.

Does automation reduce cleaning time or just labour?

Typically both. Automation reduces operator involvement while also improving consistency and coverage. Features such as automatic traversing and oscillating cleaning heads can reduce the total number of cleaning passes required.

Can modular belt cleaning systems be moved between conveyors?

Yes. Handheld Spinners, Static Spinners and Jet Systems are all portable and can be moved between conveyors throughout the factory.
