How can you ensure healthier feed?

SKIOLD Sigma cleans the grain and significantly reduces mycotoxins

SKIOLD's Planet Drum Cleaner removes up to 90% of mycotoxins in your grain

Mycotoxins are one of the most persistent challenges in modern grain production and feed processing. They typically occur when grain is exposed to moisture, heat, or poor storage conditions, enabling fungi such as Fusarium and Aspergillus to thrive. These fungi produce harmful toxins that attach themselves firmly to the outer surface of the grain.

Even grain that appears clean can contain high levels of mycotoxins. These toxins can lead to reduced feed intake, impaired growth, weakened immunity and overall poorer performance in livestock. For farmers and feed producers, mycotoxins can mean rejected grain deliveries, lower prices, and increased reliance on expensive toxin binders that only mask the problem rather than removing it.

The industry needs a solution that does more than sort impurities – a technology that effectively removes mycotoxins from the grain itself.

The SKIOLD Sigma: A mechanical cleaning principle that actually removes toxins

The SKIOLD Sigma is engineered with a centrifugal cleaning system that not only separates impurities but actively scrubs the grain surface, removing dust, fungal spores, lightweight fragments, and the mycotoxins attached to the kernel coat.

How it works:

• The grain is spun against a rotating screen drum
• Adjustable brushes apply a gentle polishing action
• Surface contaminants are detached and extracted
• Mycotoxin levels can be reduced by up to 90%
• The grain becomes cleaner, safer and far more uniform

The Sigma operates without vibrations, requires no heavy foundation, and fits seamlessly into both large and small processing lines.
Its enclosed construction ensures dust-free, low-noise operation, while self-cleaning brushes maintain optimal capacity even with oily crops like rapeseed or maize.

Unlike chemical solutions, mechanical cleaning physically removes the toxins from the system – not just from the feed ration.

SKIOLD Sigma in real life

One of the standout examples of the Sigma in action comes from a Danish pig production unit that implemented the Sigma as part of a strategy to lower toxin levels in feed.

Even when the grain appeared clean, the Sigma removed a surprising amount of dust and residues. After installation, the farm recorded significantly reduced toxin levels, improved animal health indicators, more consistent feed intake, and overall better performance across the herd.
