High shear homogenizer VS high pressure homogenizer, whose comprehensive strength is stronger?
Jun 12, 2020
In the field of medicine, homogenizers are mainly used in the homogenization and emulsification process of pharmaceuticals and other products in the production process. In addition, the homogenizer can effectively separate the sample surface of the protective body and the homogeneous sample of the contained microorganisms. The sample is packed in a disposable sterile homogeneous bag without contact with the instrument, which can meet the requirements of fast, accurate results and good repeatability.
Requirements.
According to industry reports, with the rapid development of the pharmaceutical industry, homogenizer equipment has also ushered in good development opportunities. However, there are many kinds of homogenizers in the equipment market, and their performances are different, so it is difficult for buyers to choose. In this regard, the author lists two common homogenizers: high-shear and high-pressure homogenizers, and compares the overall strength between the two.
Raw material requirements
Different equipment has different requirements for raw materials. It is understood that the high-pressure homogenizer must first melt and mix the materials into a fluid before homogenization, and the high-shear homogenizer can directly input powders, lumps or fruits.
Speed
At present, the linear velocity of shearing homogenizers commonly used in China is mostly 10-25m/s, but practice has proved that the homogenization effect is not ideal. The finger-line speed of the high-shear homogenizer can reach 30-50m/s. It is understood that its main working part is a fixed rotor with one or more stages intermeshing. Each fixed rotor has several layers of ring gears.
energy consumption
Nowadays is the era of advocating energy saving. The lower the energy consumption, the more the equipment can save costs for enterprises and get favored. High-voltage homogenizers have high power consumption, which is easy to cause energy waste. The power consumption of the high-shear homogenizer is only 1/3 of the high-pressure homogenizer, so it is more popular in the market.
Homogeneous effect
Homogeneous effect is often the only point that users choose when choosing devices. It is understood that the homogenization fineness of the high-pressure homogenizer is small, but the effect is poor in some industries. The high-shear homogenizer has a homogeneity fineness of less than 1μm and good stability.
Production operation
In terms of production operations, today's fast-paced production mode requires that equipment also need to reach the rate. It is understood that many high-pressure homogenizers currently require special personnel to operate and manual adjustment. The high-shear homogenizer is easy to operate and flexible, and does not require special personnel to operate, which can greatly reduce the manpower, material resources and energy of the enterprise, and reduce manual errors and costs for the enterprise.
Difficulty in cleaning
Easy to clean the equipment will also affect the user experience. The cleaning of the high-pressure homogenizer is complicated, and the high-shear homogenizer is an automatic design, which can realize automatic cleaning, which is simpler and more convenient, and the cleaning is thorough.
Life
It is understood that the homogenizing valves, seals and other components of the high-pressure homogenizer need to be replaced frequently after two to three months of use. The high-shear homogenizer has a long service life, and there is no need to replace accessories or wear parts in two years.
Scope of application
The industry pointed out that the high-pressure homogenizer is not suitable for high-viscosity materials, and the high-shear homogenizer has a wide range of applications. It can be used in biomedicine, food industry, daily care products, coating inks, nano materials, petrochemicals, printing and dyeing Additives, paper industry, pesticide fertilizers, plastics, rubber, power electronics and other fine chemical industries.
Comprehensive effect
From the point of view of the use of the body, the high-pressure homogenizer can only be used for homogenization alone, and the high-shear homogenizer can allow the mixing, sterilization and homogenization to be completed at the same time.
Therefore, from the above comprehensive effect, the performance of the high-shear homogenizer is more outstanding in all aspects, which is better than the high-pressure homogenizer.
