Homogenization is a process that aims to achieve a state of very fine and uniform distribution of two or more immiscible liquids (such as oil and) or solid particles in a liquid, resulting in a stable product such as dairy products, cosmetics, pharmaceuticals, food flavorings, etc. This process is essential for enhancing the, taste, appearance, and shelf life of the products.
The principle of homogenization equipment
Homogenization equipment mainly based on the following mechanisms to achieve the effect of uniformity:
High shear dispersion emulsification:Through the high tangential velocity and high frequency mechanical effects produced by the high-speed rotation of the rotor, the material is brought strong energy. In the gap between the rotor and the stator, which is precisely matched, the material undergoes strong hydrodynamic shear, friction, centrifugal extrusion, and fluid flow, etc., which makes the originally immiscible phase (such as liquid-liquid, liquid-solid) instantly refined and emulsified.
High pressure homogen: The sample is passed through a small homogenization valve under high pressure, experiencing shear, impact and cavitation effects. The high pressure difference causes the sample to accelerate and undergo physical conditions, forcing the particles to be refined and evenly distributed.
Structure
Homogenization equipment usually includes the following key parts:
Rotor and stator The rotor rotates rapidly, and the stator, which is closely matched with it, remains stationary, forming a narrow gap between the two, which is the main area where the force occurs.
Drive system: Provides the high-speed power needed for the rotor to rotate.
Pressure control system: In the high-pressure homogen, it is used to regulate and maintain the required pressure to push the material through the homogenization valve.
Cooling system: Since a large amount of heat may generated during the homogenization process, a cooling device is needed to control the temperature to ensure that the properties of the material are not destroyed.
Material in and out system Includes feed pump and discharge pipeline, to ensure the smooth flow of material.
Features
Highly efficient and rapid: Capable of quickly completing the dispersion and emulsification processes of materials.
Uniform and: The produced products exhibit high uniformity and fineness.
Adaptability: Suitable for a variety of materials, including liquid-liquid, liquid-solid phase mixtures.
Adjustability: Can be adjusted to accommodate different material properties and processing requirements by changing parameters such as speed and pressure.
Good stability: Helps in producing longterm stable products that are less likely to separate.
Diverse structures: According to application needs, there are various types available, including high-pressure homogenizers, central homogenizers, and ultrasonic homogenizers.
In summary, homogenizing equipment, through precise mechanical design and control, achieves efficient and uniform mixing of, making it an indispensable processing equipment in many industries.
