ETH of the High pressure homogenizer using the material in the special role of plunger into the valve which it is adjustable pressure, after a certain width limiting slot (work area), transient voltage loss of material at high velocity (1000-1500 M / sec) from impact on one of the components of the collision of the valve ring, three effects: cavitation, impact effect and shear effect. After treatment of the three effects,the particle size can be evenly below 100nm, the broken rate is more than 95%, it can be used for the treatment of fermentation tank samples and design, mainly used for biological engineering laboratories, pharmaceutical companies such as the scale of processing Escherichia coli and yeast samples, it is standard equipment in the development and production of biological engineering and bio pharmaceutical industry , can be used for dairy products, food and beverage, fruit juice, chemical and biological industry of emulsification, homogenate, homogenization treatment. This machine has a built-in cooling circulation system. It directly cools the homogeneous head. All the materials and pipes which contact the sample are made of 316L stainless steel. It is optional to buy two stage homogeneous modules, and can choose to buy different homogeneous valve for different applications.
