More and more businesses are focusing on sustainable business. Environmentally-friendly industrial cleaning is naturally a part of that. And that also means restricting the usage of cleaning agents for washing your crates. But how do you achieve that?
One of the starting points of environmentally-friendly industrial cleaning is that you need as little cleaning agent as possible to get your dirty crates – or other load carriers – clean again. To achieve that, you first have to ask yourself the question: ‘How do I ensure that my crates get less dirty?’ Many business owners bypass this question, because they are not aware, perhaps, that they can affect this a lot already. In the meantime, this is certainly a very important issue. Incidentally, the less dirt that gets into the crates, the less cleaning agent is needed to clean it out of the crates. So, for example, it is smart to think about how soon after they are used are the crates washed. Has the dirt had a chance to cake on?
Give the crate a knock
In most cases by far you do not avoid using a minimum quantity of cleaning agent for washing your crates every time. However, this does have a considerable effect on the quantity needed. You simply reduce this by giving every crate a ‘knock’ before it goes into the washer, which makes large pieces of dirt drop from the crate and so not go into the washing process. This is because, once again: the less dirty the crate is, the less cleaning agent is needed. For large Elpress washers – where the crates automatically rotate into the dryer using a logistical system – this ‘knock’ system is built in. But if you use a washer with manual infeed, then whoever inserts the crates is responsible for this process. If you make your employees aware of the significance of this method, they you have made a nice stop in the area of environmentally-friendly industrial cleaning.
Use Heat for Thermal Disinfection
If a lot a residual heat comes into your business process, then it is often important to put this into the cleaning process for your crates. By using thermal disinfection – disinfecting crates by exposing them to a temperature of more than 85 °C – using disinfection agents is actually superfluous. This thermal disinfection happens in an extra step – in what is known as the rinsing section – which is located between the main washing zone and the re-rinsing zone. As well as the advantage of disinfecting without disinfectant, thermal disinfection also ensures that less clean water is needed in the re-rinsing zone to rinse off the last residue of cleaning agent.
Hygienic Design of the Crate Washer
Not only do your crates also need to be cleaned well, the crate washer itself has to be cleaned every day. You also need cleaning agent for this. Due to the hygienic design of Elpress crate washers – made of stainless steel and therefore designed for water to run off them well – the quantity is, however, very limited and you save both energy and water when cleaning with the washer.
