Vacuum degassing machine, also known as vacuum deaerator, is usually used for vacuum degassing of liquid products to suppress oxidation and browning of the products. Through degassing, suspended particles can be removed simultaneously. The attached gas prevents particles from floating up and improves the appearance of the product; Reduce high temperature sterilization and foaming during filling, improve sterilization effectiveness, and minimize corrosion inside the container. Generally, vacuum degassing is carried out after homogenization, and sometimes before filling.
