Working principle of high pressure homogenizer

High-pressure homogenization is the use of high-pressure compressed liquid material flowing through the gap at high speeds and receiving strong shear forces. The liquid material is impacted on the metal ring to generate a strong impact force and the explosive force caused by the sudden drop and rise of static pressure. The process of processing the original coarse emulsion or suspension into a very fine stable emulsion or suspension with the effect of comprehensive force. When the homogeneous material passes through the adjustable gap h (generally 011 mm) between the valve seat and the valve stem, the gap is accelerated to 200 ~ 300 m / s in an instant, resulting in a huge pressure drop. When the pressure drops to The saturated vapor pressure (or air separation) of a large number of micro-bubbles at the operating temperature decreases the distance of the liquid towards the gap outlet, and the pressure increases accordingly. When the pressure increases to a certain value, the liquid starts "Boiling", rapid "vaporization", and a large number of bubbles are generated inside. The bubbles in the liquid suddenly burst and re-condensate, and a large number of bubbles are generated and burst in a moment to form a phenomenon. . The phenomenon seems to countless miniature zha bombs. The strong release of energy produces profound high-frequency vibrations. At the same time, the strong shear force generated by the strong turbulence, the softness in the liquid, the semi-soft particles are in the mixture, and the turbulent shearing The force is pulverized into particles under the combined action of force and large. The pulverized particles then impacted on the impact ring at high speed and were further pulverized and dispersed.
