Vacuum coater VC series - High percentage liquid coating (for Aqua feed, Animal Feed, and Pet Food )

High percentage liquid coating - Vacuum Coater (for Aqua feed, Animal Feed and Pet Food )

IDAH introduced vacuum coater to the market in the early 1990s. This vacuum coater is designed with a robust airtight body that can withstand the applied vacuum pressure to permit deep penetration of the liquid (oil, enzymes, etc.) to the material pores. The twin paddle mixing technology guarantees a thorough mixing of all types of extrudates and pellets with the applied liquid or powder. Up to 30% of liquid can be incorporated into the products.

The precise vacuum pressure permits deep penetration of additional liquid into the extrudates or pellet industry of

Vacuum Coating of Sinking Marine Fish Feed

Our customer in the middle east come up to us looking for an extrusion line for producing sinking marine fish feed. We introduced them to our EP-156D extrusion system and the VC-1500 vacuum coater. The vacuum coater is able to fully coat the sinking feed. As you can see in the picture, after coating of 20% (w/w) additional oil content, the feed becomes darker in color and has a smooth surface. The customer is satisfied with the result.
