Why should the emulsification tank be vacuumed?

The main function of vacuuming is to eliminate air bubbles, because when the emulsification tank is emulsifying and homogenizing, the rotation speed can reach 2800RPM. In such a high-speed situation, a large number of bubbles are easy to generate, and we vacuumize to prevent bubbles from being generated when the tank reaches a negative pressure, so as to avoid bubbles when the materials are mixed, thereby destroying the materials.
