Crate washers

The entire system is constructed out of stainless steel plates and profiles and is placed on adjustable feet. The wash tunnel is accessible by means of very practical upward folding-doors. When a door is opened during operation, the washer will stop instantly. Transport of the crates is conducted by a synthetic chain.

What is a crate washer?

The crate washers from Elpress make sure that all the dirt on the crate, such as proteins, blood residues, fasts, sticker and glue residues and dried-on dirt, is removed in a single wash cycle. This also removes the dirt that is invisible to your employees.

The crate washers always comprise a main wash zone, where the crates are cleaned and the dirt removed, and the rinse zone, where the crates are rinsed off with clean water. The crate washer from Elpress (EKW) can also be added to with a pre-wash zone, sticker remover and/or blower unit.

The crate washer ensures that you can transport products in clean crates to avoid putting the food safety of your products at risk. Read more here about the additional value of a crate washer for your business.

The standard operation of a crate washer

The crates are transported into the EKW crate washer by a plastic transport chain. The transport chain ensures that the crates are moved through the various zones.

As already mentioned, the crate washer has different (optional) zones. We inform you about each zone here:

Crate washer

Pre-wash zone of a crate washer (optional)

Here, spray nozzles clean the crates at a low water temperature (approx. 30-40 °C). This removes the blood and protein residues from the crates. The rough dirt particles are removed directly. If the temperature is too high (from 48 °C), the proteins will clump together (‘coagulate’).

Crate washer - pre-wash

Main wash zone 

In the main wash zone, spray nozzles clean the crates with hot water (approx. 50-65 °C). Fats and bacterial contaminants are removed in combination with the right chemicals. This keeps the germ count in the wash tank as low as possible.

Crate washer - main wash zone

Rinse zone 

In this zone, the products are rinsed with fresh cold or hot water, with the aim of effectively removing the cleaning/disinfectant agent. Rinsing with hot water helps with the drying of the crates. Our crate washers are designed in such a way as to enable optimal re-use of the rinse water containing the chemical residue.

Sticker removal (optional)

Special dirt killers are used (at high pressure) to accurately remove sticker and adhesive residues. The crates are turned through 90° to enable all four sides to be treated. The fine microfilter ensures that the washing water remains free of small particles and is suitable for re-use.

Blow off unit (optional)

In the blow off unit, air is blown over the crates by powerful stainless steel fans.The intelligent Elpress design heats the air (partly through recirculation) up to approx. 50 °C, which results in an even better blowing capacity. Depending on the type and desired result, a minimum amount of moisture remains in the crates after leaving the blow off unit.

Crate washers, designed down to the smallest detail

The crate washer is designed down to the smallest detail. For example, it stops cleaning if the doors are opened during the cleaning cycle. The water supply is also shut off when there are no crates to be cleaned. This prevents the unnecessary wasting of water and also saves energy. The cleaning process has also been fully considered. The crate washer has a phased cleaning cycle process that consists of various cleaning zones:

  • There is a pre-wash zone, where large particles of dirt can be directly removed
  • A main wash zone, where grease and bacteria are removed
  • A sticker removal zone, where sticker and adhesive residues can be (optionally) removed
  • A rinse zone, where the contents are rinsed to remove detergent and disinfectant
  • A blower unit, where everything is blown dry by fans

Various crates in a crate washer


Load carriers come in different shapes and sizes. CBL-crates, E2-crates and fish crates. It is often possible to clean different types of crates in a standard crate washer. But it is important that the side of the crates that are put into the washer is reasonably uniform. So that the different types of crate run smoothly over the washer's guides. It is therefore important that this side has approximately the same width for all the crates, and that they do not differ too much in their design (the presence of indentations or cut outs).

Adding to crate washers later on

Have you purchased a crate washer to wash a certain number of crates per hour or per day, but your business is growing? A crate washer can be expanded at any time in the future. However: there is a ‘but’ here.

Adding to a crate washer requires a considerable ‘alteration’ of the machine. So expanding a crate washer is also time-intensive and a relatively big investment.

Visual inspection system
for crate washers

The new visual inspection system makes it possible to check whether a crate has exited the crate washer in a clean and intact state. Five cameras are used to thoroughly inspect the inside and outside of the crates. Photos are taken at several points and the system can tell within just one second whether the crate is clean as well as intact.

Advantages

  • Raises hygiene to a higher level
  • Suitable for high volumes
  • Fewer staff needed
  • For universal use on all crates
  • Self-learning system
  • More reliable than checking by eye
  • Demonstrable results for audits
  • Contributes to the obtaining of HACCP and ISO certifications
