The emulsifier is called an emulsifier because of its emulsification effect; it is equipped with a vacuum function, which is called a vacuum emulsifier; the function of high-speed shearing is also called a high-shear emulsifier. The emulsifier has the functions of emulsifying, dispersing, homogenizing, shearing, grinding, heating, etc., and is often called the name related to these functions. In addition to the appropriate emulsifier, the influence factor of the realization of emulsification and the emulsification effect is the influence of the shear force of the emulsifier equipment. Let's take a look at the influence of the shear force of the vacuum emulsifier on the emulsification effect.
To achieve emulsification, two factors are required. A suitable emulsifier can serve as a medium for the immiscible oil phase and water phase molecules to fuse with each other. Acting as a bridge or medium between the water molecules and the oil structure, the emulsion of oil and water will be stably stored according to our expected time through the action of electric charges and intermolecular forces. Another factor is that strong mechanical shear dispersion is required to cut and disperse the fluid medium in the oil and water phases into fine particles, and then the particles are aggregated and combined together and mixed with each other to form an emulsion.
The shear force of the vacuum emulsifier will affect the final fineness. After analysis, it is mainly related to the sharpness and hardness of the stator and rotor blades, the gap between the rotor and the stator, the moving speed of the two blades, and the diameter of the particles allowed to pass through the stator and rotor gap. Generally speaking, the sharpness, hardness, rotor-stator clearance and approved particle diameter of the blade are finalized and no longer change, so the speed of movement of the two cutting blades is the most important factor affecting it. It turns out that the higher the circumferential linear speed of the rotor (stator is fixed), the higher the density of fluid cutting and impact. Therefore, the fineness is stronger. vice versa. However, this does not mean that the higher the linear velocity, the better. When the linear velocity reaches a very high value, it is easy to form a resistance trend and the flow will become smaller. Finally, the device is prone to overheating. If the machine is not equipped with a cooling system, some raw materials will agglomerate together, which will have a bad influence on the dispersion and homogenization effect of the emulsification, and the emulsification effect will not reach the ideal state.
