What are cleaning systems?

The term cleaning systems refers to the process involving the thorough cleaning and disinfection of production environments, equipment and infrastructure across a wide range of industries. The aim is to maintain a high level of hygiene and comply with strict regulations in the areas of food safety and production efficiency. Cleaning machines focus on removing dirt, bacteria and other contaminants that could compromise product quality and safety. 

Industrial cleaning in 3 steps

Industrial cleaning is often performed in three main steps:

1. Rinsing: Rinsing is the first step in the cleaning process and involves the removal of loose dirt and dust from surfaces and equipment. Doing this makes the next steps in the process more efficient. It helps to prepare surfaces for deeper cleaning without the need for aggressive cleaning agents and creates a clean starting point for the rest of the process.

2. Foam cleaning: In this phase, a foam cleaner is applied to loosen stubborn dirt such as grease, proteins and bacteria. The foam ensures that the cleaning agent remains on the surface longer, resulting in intensive and thorough cleaning. Foam cleaning is ideal for removing organic residues such as grease and proteins, as the foam remains on the surface longer and is therefore more effective at loosening dirt. This ensures deeper cleaning, even in hard-to-reach places.

3. Disinfecting: The last step is disinfecting, in which chemicals are used to kill bacteria, viruses and other micro-organisms. This is crucial in sectors where hygiene is essential, such as the food industry and pharmaceutical production. Chemical disinfection is necessary to eliminate microorganisms such as bacteria and viruses. This is critically important in environments such as the food industry and the pharmaceutical sector, where absolute hygiene is essential to prevent contamination.

Low-pressure cleaning systems are the most commonly used

Cleaning machines are often operated at low pressure because this is an effective way to remove dirt without damaging sensitive surfaces. Low-pressure cleaning is also a sustainable choice. Additionally, low pressure is frequently combined with foam cleaning, as it enables deeper cleaning without any of the associated risks.

When to clean using low pressure

Low-pressure cleaning is used in situations requiring gentle but effective cleaning, for example when cleaning surfaces that are susceptible to damage or are only lightly soiled. Examples of low-pressure cleaning: 

  • Food processing: Foam cleaning of production lines, machines, walls, floors, workbenches, etc.
  • Dairy industry: Cleaning of milk tanks and lines to remove residues and bacteria.
  • Pharmacy: Cleaning of cleanrooms, where absolute hygiene is required to prevent contamination.
  • Horticulture: Cleaning of greenhouses and cultivation trays to prevent the growth of mould and other pathogens.
  • Agriculture: Cleaning of agricultural vehicles such as tractors, ploughs and sowing machines to remove dirt and manure.
  • Poultry industry: Cleaning of poultry houses and egg processing equipment in order to ensure hygiene and prevent the spread of disease.

The advantages of cleaning at low pressure:

  • Safe for equipment: Suitable for the cleaning of sensitive and complex systems such as a electronic control units (PLCs) without the risk of damage.
  • Lighter workload: Working with low pressure requires less physical effort from the user, which in turns makes the work less tiring.
  • Energy efficient: Due to the lower power consumption, it is more energy efficient compared to high-pressure systems.
  • Less noise: Produces less noise than high-pressure pumps, which leads to a more pleasant working environment.

Centralised cleaning vs. decentralised cleaning

Centralised cleaning makes use of a single centralised system for cleaning several production areas, while decentralised cleaning involves the use of separate systems for specific areas. Both methods have their pros and cons, depending on the existing infrastructure and the specific cleaning needs of the business.

  • Pros and cons: Centralised cleaning can be cost-effective for large companies, while decentralised cleaning offers greater flexibility for smaller or more specialised operations.
  • Existing building / new building: The choice between centralised and decentralised cleaning can also depend on the age of the business premises. Centralised cleaning can be integrated into a new buildings more easily, while decentralised cleaning might be more practical in existing buildings.

Centralised cleaning can be cost-effective for large companies with a lot of cleaning points, while decentralised cleaning offers greater flexibility for smaller or more specialised cleaning processes. When deciding which of these two methods to use, remember to take your company’s infrastructure and your specific cleaning needs into account.

Cleaning systems with a combination of high and low pressure

The pressure inside a cleaning machine can vary from low (e.g. 10-30 bar) to high (>60 bar), depending on what has to be cleaned. The choice of operating pressure depends on the kind of dirt, the surfaces to be cleaned and the desired result.  Low pressure is often preferred for surfaces that are susceptible to damage, while high pressure is used to remove stubborn dirt. This combination offers flexibility and ensures that the cleaning is both effective and safe.

Cleaning systems with high pressure: stubborn dirt

High-pressure cleaning is used on stubborn dirt that is hard to remove and cannot be loosened with low pressure. High-pressure cleaning is especially effective for removing burned-on dirt, grease and other stubborn residues.

Examples of high-pressure cleaning: 

  • Food processing: Cleaning of abattoirs, where blood, fat and other residues have to be thoroughly removed.
    Dairy industry: Cleaning of pasteurisation and sterilisation equipment that requires intensive cleaning to comply with hygiene regulations.
  • Pharmacy: Cleaning of fermentation tanks and reactors to remove residues of chemical processes.
  • Horticulture: Cleaning of surfaces at the end of the growing season in order to remove pesticides, fertilisers and other chemicals.
  • Agriculture: Cleaning of silos and storage tanks for feed, grain or fertiliser to prevent the accumulation of harmful substances.
  • Poultry: Disinfecting of concrete slabs around the sheds to eliminate pathogens that can accumulate on these surfaces.

Important advantages of high-pressure cleaning:

  • Economical: High-pressure pumps use water sparingly
  • Suitable for heavy dirt: They are suitable for removing heavy or baked-on dirt.

Is high-pressure cleaning suitable for the food industry?

Although high-pressure cleaning (>60 bar) appears to be effective for removing stubborn dirt, it is often not recommended in production environments with open food processing. This is because the use of high pressure entails two major risks:

  1. Formation of aerosols (QA risk): At high pressure, the water rebounds from the surface with great force. This creates water mist (aerosols) that disperses dirt particles and bacteria through the air. These can settle on already cleaned surfaces, leading to cross-contamination and listeria risks.

  2. Damage to equipment (TD risk): The impact of a high-pressure jet can damage vulnerable components such as sensors, gaskets, and control boxes, leading to unnecessary malfunctions and maintenance costs.

Get more out of your cleaning system with a service contract

Regular maintenance is essential for ensuring that an industrial cleaning system remains in tip-top condition. You can do the maintenance yourself or leave it to your employees, but often there is not enough time or knowledge to do this effectively. To provide support with this, Elpress offers service contracts. With a service contract, an Elpress service engineer will visit from time to time, mostly annually but more frequently if necessary, to carry out thorough maintenance on your cleaning machine. This ensures that your system carries on working efficiently and minimises the risk of malfunctions and defects.

Frequently asked questions

Below are some frequently asked questions about cleaning systems. 

Which parts of a cleaning cycle are easily measurable?

Consider times per function (rinsing, foaming, rinsing, disinfecting), component service life, and deviations in patterns or consumption. This allows you to see where the process deviates from the desired method.

How does eCloud help you maintain control over hygiene?

When you purchase eCloud, data can be stored and analyzed. This gives you insight into usage, times, deviations, and trends over a longer period, which helps you make more targeted adjustments and substantiate improvements.

eCloud can be used with cleaning systems, hygienic entrances, and industrial washing systems. 

Can eCloud data also help with maintenance and malfunctions?

Yes. When downtime, deviating patterns, or sudden changes become apparent, this can be a signal to schedule maintenance or investigate a technical problem (e.g., components that are performing differently).

Where does waste occur most often in the cleaning process?

Waste occurs mainly at times when the cleaning process is not visible or measurable. This often happens outside of production time, when there is no supervision and deviations are not immediately noticed. Examples include unnecessarily long rinsing times, incorrect use of chemicals, or cleaning without a nozzle.

What are the biggest cost factors associated with waste during cleaning?

In addition to higher water and chemical costs, energy costs and maintenance also play a role. Hot water, pumps, and installations run longer than necessary, and wear and tear on hoses, couplings, and components increases more quickly.

How can you take technical measures to reduce waste?

By setting limits for water and chemical consumption, applying time limits, and activating blockages in the event of incorrect use. This allows the system to intervene when consumption is out of line, without the need for manual control.

Can eCloud also be linked to other hygiene systems?

In some situations, eCloud can also provide insight into data from other hygiene systems, such as hygienic entrances or washing systems. What is possible depends on your installation and the chosen configuration.

What is the difference between a traditional and an intelligent satellite?

A traditional satellite supplies water and chemicals, but does not measure or record anything. An intelligent satellite measures usage, can set limits, and communicates data to a central system.

Are smart satellites only interesting for large companies?

No. It is precisely in environments with multiple consumption points or changing shifts that they provide insight and control that would otherwise be lacking.

Can I expand existing installations with smart satellites?

In some cases, this is possible. It depends on the current installation and the desired functionality.

How do smart satellites help with audits?

They provide insight into usage and consumption per point, allowing you to better explain how processes work and where deviations are monitored.

Is RFID mandatory for smart satellites?

No. RFID is optional and is mainly used when traceability or role-based use is desired.

What does implementing eCloud require from my organization?

An analysis of the current system, clear agreements on rights, and instruction of employees. This is followed by optimization based on data.

Where do I start if I want to switch to smart cleaning?

Start with insight: where is the most consumption, where do errors occur, and where is control lacking? From there, you can determine which functions and configuration are appropriate.
