[0002] High pressure homogenizer is a kind of equipment for the refinement and homogenization treatment of the particles in liquid, and its working principle is to deliver material to a narrow homogenization valve by high-pressure pump, under the action of extremely high pressure (usually 100-600MPa), material passes through the gap of homogenization valve at extremely high speed, when material passes through the gap, strong shear force, impact force and cavitation effect are generated. Shear force is caused by the speed difference between fluid layers when material passes through narrow gap at high speed;Impact force is generated by the mutual collision between material and the wall of homogenization valve and the particles inside the material;Cavitation effect is that small bubbles are formed in liquid under high pressure, when pressure is suddenly released, these bubbles burst to generate strong impact force, thereby breaking large particles into small particles, so that material achieves the effect of uniform refinement.
