Vacuum coaters for high liquid addition in feed production

Enhance your feed production with precision liquid coating, saturating pellets to their core for improved nutritional delivery and product quality. Ideal for seamlessly integrating into your existing processing line, this solution ensures consistent results batch after batch.

Adds Liquids and Coats Pellets Evenly

Ottevanger Milling Engineers’ DPMA series vacuum coaters are engineered to significantly enhance liquid incorporation into pellets, improving the quality of aquatic feed, pet food, and livestock feed. The vacuum coating process penetrates the pellet core, ensuring uniform distribution of liquids such as oils and enzymes. Available in sizes from 500L to 2800L, they are well-suited for both batch and continuous operations. Constructed from durable stainless steel grades 304 and 316, they offer superior resistance to corrosion, making them ideal for demanding processing environments. With low energy consumption and easy integration into existing production lines, these machines cater to aquatic feed producers, pet food manufacturers, and feed production companies seeking efficient and reliable processing solutions. Additionally, they support variable operation modes and are equipped with a comprehensive liquid dosing system for precise ingredient delivery.

Benefits

  • Ensures precise liquid saturation for improved pellet digestibility and nutritional value.
  • Minimizes energy usage, lowering operational costs.
  • Provides corrosion-resistance for longevity in harsh environments.
  • Reduces manual intervention with automated liquid dosing system.
  • Enhances production flexibility with batch and continuous operation modes.
