Continuous coater for pellet and extrudate liquid addition
In the production of animal feed, ensuring that liquids such as oils, vitamins, and enzymes are evenly distributed on pellets or extrudates can be challenging. Uneven coating may lead to inconsistencies in the final product, affecting its quality and efficacy.

Add liquids evenly on pellets and extrudates
The Continuous Coater from Ottevanger Milling Engineers is designed for the efficient and uniform addition of liquids onto pellets and extrudates. This coater utilizes a spray box through which the liquids are slowly mixed with the products, ensuring an even coating. It features a stainless or mild steel trough with a 50 mm thick insulated jacket, which helps stimulate the absorption of the liquid while avoiding contamination. The coater is equipped with hinged inspection hatches along the full length of the mixing trough to facilitate easy access for inspection and maintenance. Additionally, the coater can mix various liquids, including oils, fats, vitamins, and enzymes. Variable heating systems within the jacket enhance the efficiency of liquid absorption. The dosing systems for different liquids can be customized based on specific requirements.
