What is a Vacuum Spray Coating Machine?

Responding to the pressing demand for advanced low-oil spray solutions, our company has developed an exceptional Vacuum Spray Coating Machine based on the concept of high-oil spray with a vertical agitator. By refining our existing series of vacuum spray machines, we eliminated the need for a vacuum pump and introduced a vertical spray machine for extruding particles. This modification not only reduces costs but also provides customers with an affordable investment option.
