Advanced vacuum coating system for pet food and feed
Achieve uniform saturation in pellets and granules with precise liquid application using vacuum technology, enhancing nutritional content and integrating seamlessly into your production line for efficient mixing and coating.

Infuses and Coats Granules and Pellets with Liquids
The Pegasus® Vacuum Coater from Dinnissen is a specialized solution for efficiently infusing granules and pellets with liquids. Its unique working principle involves a double-axis paddle mixer that ensures homogeneous mixing within a vacuum environment. This process allows for deep penetration of oils, vitamins, and other additives, making it ideal for applications in pet food, aquafeed, nutraceuticals, and pharmaceuticals.
With its ability to process various product types, the Pegasus Vacuum Coater can handle batch and continuous operations. It offers high-speed and automated functionality, integrating seamlessly into existing production lines. One of its standout features is the ability to reduce the boiling point, thereby preserving the quality of sensitive ingredients. The coater is available in several material options to ensure compatibility with diverse chemical products and complies with stringent hygiene standards, including GMP.
The system’s design facilitates easy cleaning through large inspection hatches and optional CIP systems, crucial for maintaining hygiene and preventing cross-contamination. Dinnissen provides customization options, including adjustable vacuum levels and removable paddle welds, supported by comprehensive engineering expertise to tailor the equipment precisely to your operational needs.
