Working principle of high-pressure homogenizer

A high-pressure homogenizer is a device that uses a high-pressure reciprocating pump as a power transmission and material conveying mechanism to transport materials to the working valve (first stage homogenization valve and second stage emulsification valve). In the process of handling materials, the material will undergo strong shear, impact, and cavitation under high pressure when passing through the working valve, resulting in ultrafine refinement of liquid substances or solid particles carried by liquids.

Working principle of high-pressure homogenizer
The working valve is a key component of a high-pressure homogenizer. When the material has not yet passed through the working valve, the valve core and valve seat of the first stage homogenization valve and the second stage emulsification valve are tightly adhered together under the action of force F1 and F2. When the material passes through the working valve, the valve core and valve seat are forced to open a narrow gap by the material, while generating pressures P1 and P2 respectively to balance forces F1 and F2. During this process, the pressure drops suddenly from P1 to P2, causing a sudden release of pressure energy, resulting in a strong cavitation effect similar to an explosion effect in the narrow area composed of the valve core, valve seat, and impact ring. At the same time, accompanied by the shear effect generated by the material passing through the narrow gap between the valve core and valve seat, as well as the high-speed impact effect generated by the impact with the impact ring, this strong comprehensive effect causes the particles to be ultrafine refined.
