The vacuum emulsifier has fast homogenization and good homogeneous emulsification effect. The following is a summary of the structure, composition and operation of the vacuum emulsifier.
Vacuum emulsifier has fast homogenization, good homogeneous emulsification effect (particle size 1um), heating and cooling and vacuum degassing, sanitary conditions for production, in line with national standards, high thermal efficiency, reliable electrical control, stable operation, convenient operation and maintenance, low labor intensity Low-level features and benefits. This unit is suitable for the production of ointment and cream products in cosmetic factories and pharmaceutical factories, especially for the emulsification of materials with high viscosity and high solid content.
Vacuum emulsification machine is mainly composed of pretreatment pot, main pot, vacuum pump, hydraulic pressure, electrical control system and so on. The materials in the water pot and the oil pot are fully dissolved and then sucked into the main pot by vacuum for mixing and homogeneous emulsification. The operation of the vacuum emulsifier means that the material is in a vacuum state, and the high-shear emulsifier is used to quickly and evenly distribute one or more phases into another continuous phase, and the strong kinetic energy brought by the machine is used to make the material in a fixed state. In the narrow gap of the rotor, it is subjected to hundreds of thousands of hydraulic shears per minute. Centrifugal extrusion, impact, tearing and other comprehensive effects can instantly disperse and emulsify evenly, and after high-frequency cycles, finally obtain a fine and stable high-quality product without bubbles.
What we need to pay attention to when operating the vacuum emulsifier is that the vacuum emulsifier must be tested after installation. This test run is generally carried out in two different states, that is, no-load test run and load test run. It is to investigate the nature of the vacuum emulsifier device and to discover the existing problems in advance. When the vacuum emulsifier is in trial operation, it is necessary to inject about 70% of the equipment volume into the pot, and the agitator cannot be turned on and off when there is no water in the pot of the vacuum emulsifier, so as to avoid the homogenization head from heating and sintering during high-speed operation. . In particular, it should be noted that the no-load test is at least 2 hours, and the load test is at least 4 hours, and always pay attention to the changes in the operating conditions of each component after the load changes.
The above is a brief introduction to the vacuum emulsification machine!
