I. Understanding the Vacuum Homogenizing Emulsifying Mixer
(I) Equipment Types
There are various types of vacuum homogenizing emulsifying mixers to meet different production needs. For example, there is an efficient stirring type designed specifically for low-viscosity liquids, which can quickly achieve uniform mixing; and a powerful shearing type for high-viscosity materials to ensure full emulsification. Additionally, there are large-capacity types for industrial production that can handle a large amount of raw materials, suitable for large-scale production; and compact types for small laboratories, which are convenient for small-scale experiments and research and development.
(II) Key Components and Their Functions
Stirring Blades: Rotate at high speed to stir, shear, and emulsify the materials, enabling thorough mixing of different components.
Vacuum System: Creates a vacuum environment to effectively remove air bubbles, prevent material oxidation, and improve product stability and fineness.
Heating/Cooling Device: Precisely controls the material temperature to meet the temperature requirements of different processes and ensure the smooth progress of reactions.
Tank: Serves as a container for holding materials, and its material and structural design affect the durability and cleaning convenience of the equipment.
Control System: Allows operators to set and adjust parameters such as stirring speed, temperature, and vacuum degree, and monitor the equipment's running status in real-time.
