Vacuum coaters for high liquid addition in feed production
In feed production, especially in aquatic feed and pet food plants, accurate and efficient addition of liquids such as oils and enzymes into pellets is crucial. Traditional methods often fail to ensure homogeneous distribution and deep penetration of these additions, leading to inconsistent quality and performance.

Ensure homogeneous liquid addition in pellets
The vacuum coaters by Ottevanger Milling Engineers are specialized in adding high percentages of liquids to pellets and extrudates, using a batch-wise process. The vacuum process ensures that liquids penetrate into the core of the pellet, enhancing consistency and quality. These coaters are highly versatile and compact in design, allowing them to fit various production settings. They are specifically beneficial in industries like aquatic feed plants, where they can add pigments and micro-ingredients up to 30%. In pet food plants, they can add oils and fats up to 17%, while in general feed production, they handle up to 8% additions of Phytase enzymes and vegetable oils. The models range in capacity from 500 to 2800 liters, and come equipped with a low energy consumption feature, further enhancing operational efficiency. They are available in stainless steel grades 304 and 316, ensuring durability and hygiene.
