Automatic cleaning of smoking ovens halved the chemical consumption and cleaning time
At Danish Crown in Svenstrup, a new System Cleaners solution ensures a better working environment, less chemical consumption and better cleaning of 13 smoking ovens.
Less chemicals – better cleaning
In addition to the work involved, the use of chemicals for cleaning the smoking ovens has halved.
“This is because the chemicals are mixed with both air and water and at the same time the chemicals are distributed better in the oven as it operates with a different pressure. The new method also makes it possible to operate in several partial processes in which chemical are added, rinsed off and the process repeated 3-4 times during the course of cleaning,” says Peter Erik Møller.
The installation is equipped with a manual valve system, which has to be activated to start the cleaning.
“We have not opted for a fully automatic system as we wanted to be entirely certain that we do NOT start the cleaning of an oven when there are products in it,” explains Peter Erik Møller.
Many years of collaboration with System Cleaners
Danish Crown in Svenstrup has used System Cleaners as its supplier of cleaning solutions for more than 20 years.
"Over the years it has been shown that System Cleaners produces very reliable solutions and also equipment which we can maintain ourselves,” says Peter Erik Møller, who rarely sees visits by service technicians.
“When we clean, we are under a certain amount of pressure. We have to be ready for production to start again, so it is a great advantage that we ourselves can change packs, for example, and receive support by telephone if necessary,” Peter Erik Møller emphasises.
Should there be a breakdown and service be required he also has some praising words.
“System Cleaners is very service-minded and we know that they always have wearing and replacement parts of the right quality which can be delivered in a few hours or collected directly at the factory,” stresses Peter Erik Møller.

Modernisation and automation with System Cleaners’ automatic main station
At the 56,000 m2 processing plant in Svenstrup, Danish Crown produces sausages and for the last 20 years has used System Cleaners cleaning solutions.
In the autumn of 2015, there was a need for simpler cleaning of smoke flues in 13 smoking ovens, which are cleaned every 6 weeks. Prior to the new installation, chemicals were mixed manually in large tubs whereby an employee personally filled chemicals into the tub and carried out cleaning manually.
The aim was to create an installation that, with a high degree of automation, could increase safety of the personnel, provide better cleaning and reduce the use of chemicals.
It was particularly important for the system to keep channels, dampers and drains free of soot and tar that could otherwise end up on the products.
The new solution has a centrally located, automatic mixing station, which mixes water and chemical components. The installation is set up so that with just one station it is possible to clean all 13 smoking ovens from the central unit.
The chemicals are placed centrally in the installation without risk of contact during personnel utilisation.
The use of chemicals has halved compared with before. This is good both economically and environmentally. At the same time far fewer man-hours are connected with cleaning.
Cleaning takes place with fixed-mounted jets in the smoke channels, which assure more uniform cleaning.
