Continuous coater for pellet and extrudate liquid addition
Efficiently enhance your feed products by uniformly adding liquids such as oils, vitamins, and enzymes, ensuring optimal absorption and quality. With this continuous coater, achieve consistent mixing and dosing, pivotal for final conditioning in large-scale feed production.

Applies Liquids Evenly to Pellets and Extrudates
The Continuous Coaters from Ottevanger Milling Engineers deliver precision in applying liquid coatings to feed pellets and extrudates. These coaters employ a sophisticated spray box system to ensure uniform liquid distribution, ideal for applications in pet food, aqua feed, and compound feed production. With capacities ranging from 1 to 40 tons per hour, they easily integrate into large-scale, automated production lines, bolstering efficiency and product quality.
Constructed with stainless or mild steel and featuring a 50 mm insulated jacket with heat tracing, these coaters enhance liquid absorption while preventing contamination. The hinged inspection hatches along the mixing trough simplify cleaning and maintenance, vital for minimizing downtime. Multiple dosing systems for oils, vitamins, and enzymes allow for versatile product enhancement.
Options for customization and engineering support further ensure that these coaters meet specific operational requirements. Their robust design and variable heating system align with rigorous production demands, making Ottevanger Continuous Coaters an integral part of any feed production process.
