Three ways to optimize grain cleaning

Mads Rauff, owner of Sjørup Pig Production, and the manager Brian Søndergaard has implemented three new initiatives to achieve better results by cleaning the grain.

The initiatives came to life as it was established at Sjørup Pig Production that every time a silo came close to being empty the feed intake was reduced, milk production decreased and there were challenges with general sow health.

In these periods the team at Sjørup Pig Production saw that even though they added one to two kg of toxin binder per tons of feed they didn’t see any remarkable improvements in terms of overall effect.

The three initiatives were:

• Improve the lifetime of old silos by constructing a new bottom that could air the grain


• Better and more efficient cleaning by installing a new SKIOLD Sigma grain cleaner


• Continuous tests for toxins to analyse the reduction of toxins

After the Sigma grain cleaner has been implemented and used at Sjørup Pig Production the improvements are very clear. Installing the Sigma is the initiative that has had the largest impact. The cleaning principle in Sigma is more efficient compared to other types of cleaners when it comes to removing toxins.

It was a surprise to the owner, Mads Rauff, and manager, Brian Søndergaard, how much waste that could be removed from the grain – even though it seemed quite clean before the cleaning.

A thorough cleaning improves efficiency and stability. The toxins are attached to the surface of the grains and Sigma has a great impact on this because of the specific way it works. Furthermore, it also contributes to an efficient cleaning and a lower level of toxins by removing large quantities of sand, unwanted seeds etc.
