What is vacuum coating?
What does it do?
Vacuum coating is a processing technique that can be used to add value to your product. It allows producers in the feed, aqua feed and petfood industry to drastically improve the quality and characteristics of their products. This is done by adding functional additives such as enzymes, vitamins and drugs, end of line. By using vacuum coating technology, these additives penetrate homogeneously into the entire pellet. This results in better, more nutritious feed and (pet)food, healthier animals, and less emissions.

How does it work?
The magic of Pegasus® Vacuum Coating explained
- The process starts with your product being fed into a Pegasus® Vacuum Coater in atmospheric conditions.
- Then the vacuum unit creates a vacuum environment in the mixing unit.
- The Pegasus® Vacuum Coater gently suspends ingredients homogeneously in the air, in vacuum conditions.
- Whiles this happens precisely predetermined quantities of liquids can be sprayed onto the powders, pellets or granules.
- When air is then allowed to enter the mixing unit, the liquids are evenly distributed deeply into each particle. The ingredients being sucked deep into the particles through the vacuum, also has the effect of protecting them against crumbling.
- After this step, additional layers of top coatings or aromas are applied to each particle, which results in a high-quality extruded product.
- Often a thin layer of fat is applied to the granular feed material. This extra protective layer makes the material more elastic so that it breaks or crumbs less quickly.
- All this is done very fast, the entire batch process takes just a couple of minutes!
