Vacuum emulsifying machine high shear working process

Release time:

2022-09-09

Vacuum emulsifying machine stirring speed is moderate to make the oil phase and water phase fully mixed, stirring speed is too low, can not achieve the purpose of full mixing, but the stirring speed is too high, will bring bubbles into the system, making it a three-phase system, and make the emulsion unstable. Therefore, the air must be avoided in the mixing, and the vacuum emulsifier can meet this condition. Let's follow Tianfu to see the high shear working process of vacuum emulsifying machine:

vacuum emulsifying machineModerate stirring speed is to make the oil phase and water phase fully mixed, stirring speed is too low, can not achieve the purpose of full mixing, but the stirring speed is too high, will bring bubbles into the system, making it a three-phase system, and make the emulsion unstable. Therefore, the air must be avoided in the mixing, and the vacuum emulsifier can meet this condition. Let's follow Tianfu to see the high shear working process of vacuum emulsifying machine:


1. Under the action of the centrifugal force generated by the high-speed rotating rotor, the material is sucked into the working chamber from the axial direction from the upper and lower feeding areas of the working head.
2. The strong centrifugal force throws the material from the radial direction into the narrow and precise gap between the stator and the rotor. At the same time by centrifugal extrusion, impact and other forces, so that the initial dispersion of the material emulsification.
3. At the outer end of the high-speed rotating rotor, a linear velocity of at least 15 m/s is generated, which can be as high as 40 m/s, and strong mechanical and hydraulic shearing, liquid layer friction and impact tearing are formed, so that the materials can be fully dispersed, emulsified, homogenized and crushed, and injected through the stator slot at the same time.

Industry Development of Emulsion Machine

Emulsification machine is through the high-speed rotation of the homogenization head connected with the engine to shear, disperse and impact the material. In this way, the material will become more delicate and promote the melting of oil and water. Widely used in cosmetics, shower gel, sunscreen, and many other cream products are used in the emulsifying machine. Sauce, juice, etc. in the food industry. Ointments in the pharmaceutical industry. Petroleum chemical industry, paint ink, etc. will use the emulsifying machine. Industry development: 1. China's emulsifying machine tool has become one of the strengths of China's processing industry. Among them, the vacuum homogenization emulsifying machine and the high-shear emulsifying machine are all advanced in the world in the past few years.
