Vacuum Coater
The vacuum coater is an advanced machine for adding oil, fat and other liquid additives to pelleted and extruded products. By creating a vacuum in the chamber, it removes the air in the product's pores and, after liquid injection, allows deeper and more uniform penetration of the additives into the internal structure of the particles.

Frequently Asked Questions
What is the difference between a vacuum coater and a rotary coater?
In a rotary coater, liquids are mainly sprayed onto the product surface; in a vacuum coater, the vacuum also lets liquids penetrate the product's internal pores.
Is the vacuum coater suitable for aquatic feed?
Yes, especially for extruded fish and shrimp feeds that need a high fat percentage.
Can the amount of injected oil be adjusted?
Yes. The oil quantity can be set according to the formulation through the control system and measuring equipment.
