The principle of emulsifying machine

An emulsifier is a device that mixes and disperses liquid or semi-solid substances into small particles through mechanical shear and high-speed rotation. It is mainly used in industries such as chemical, pharmaceutical, and food, and has a wide range of applications.

The emulsifier mainly consists of a transmission system, a machine head, a rotor, a stator, a discharge device, etc. The head is the core component of the emulsifier, the rotor is the rotating part inside the head, the stator is the fixed part inside the head, and the discharge device is the component that discharges the emulsified mixture.

The emulsification principle of the emulsifier is to use the shear force, impact force, and friction force between the high-speed rotating rotor and stator to emulsify the mixture. During the emulsification process, the mixture undergoes thousands of shear and tearing actions by the rotor and stator, causing its particle size to continuously shrink and form small to nanoscale particles, thereby achieving a uniform dispersion of the mixture

The emulsification effect of an emulsifier is influenced by various factors, including rotational speed, shear frequency, head form, working temperature, and material properties. The rotational speed and shear frequency are the most important factors, and the larger their coefficients, the better the emulsification effect. The form of the machine head also affects the emulsification effect, and different forms of machine heads are suitable for different materials and mixtures of different particle sizes. The working temperature also affects the emulsification effect, as the properties of the material change with temperature. Therefore, the temperature should be controlled well to ensure the best emulsification effect.

The emulsifying machine adds some substances that are difficult to disperse into the emulsifying machine, such as oil, water, spices, emulsifiers, etc. In the high-speed rotating head, substances produce strong force through the high-speed rotating rotor shear, friction, impact force, so that the dispersed particles continue to reduce, eventually forming a uniform and small lotion state.
