A vacuum liquid coater of the SYPZ series is automatically controlled by a computer with a few operating parameters. It is only necessary to input the output-to-oil ratio, the system will run automatically, so the operation is very convenient. The coater features high accuracy of coating proportion and capacity, and with excellent coating evenness. And the feed machinery is characterized by its favorable vacuum degree and vacuum retention.
When pellets enter the vacuum mixer, the mixer trough is vacuumized by a vacuum pump until the air inside the trough is exhausted, and at the same time the air in the pores of the pellets is evacuated. When the vacuum degree is reached, liquid is sprayed and coated on the surface of "air-empty" pellets while mixing. After mixing, the valve of the mixer is opened to release the vacuum and the liquid is pressed into the micro pores of the pellets due to the pressure difference between the inside and outside of the mixer trough.
