Classification
From the principle of homogeneous cavity structure, it is divided into:
First generation collision type
A. Cavitation nozzle type - directly refers to the cavitation nozzle structure in high-pressure cutting and aerospace propulsion technology, but due to the ultra-high pressure, the material solution will generate several times the speed of sound when passing through the valve core with a very small aperture. It has a fierce friction and collision with the internal structure of the valve core, so its service life is short and accompanied by metal particles.
B. Collision valve body type - through the introduction of the impact valve and impact ring structure, reduce local wear and prolong the service life of the homogenization chamber. However, since the fundamental principle is that the material in the solution collides with the structure of the high hardness metal (such as tungsten alloy), the problem of wear and tear of the metal particles is not completely solved, and as of 2013, most of the domestic high pressure homogenization This structure is used in the machine.
Second generation
C. The Y-shaped interaction type - the fundamental difference is that it applies the principle of jet flow. The unique Y-shaped structure makes the high-speed moving materials in the high-pressure solution collide with each other, greatly improving the service life of the cavity and solving the problem of metal particles falling.
In the first generation of collision-type homogenizing chambers, in the production of medical injections, residual inert metal particles may aggregate or form larger particles. From a pathological point of view, it will lead to a decrease in capillary blood flow, which in turn causes mechanical damage to tissues in the human body and causes acute or chronic inflammatory reactions. The birth of the uniform-type homogeneous cavity solves the problem of inert metal residue in principle. However, due to the internal structure, when the concentration and viscosity of the material are large, the second-generation radiation type is more likely to block than the first generation.
Method of choosing
Homology principle selection
The high pressure homogenizing chamber is the core component of the high pressure homogenizer and is the main factor determining the homogenization effect. The high-pressure homogenizing chambers with different internal structures have different use ranges and homogenization effects. Specific comparisons and selections can be found in the table below.
Homogeneous cavity parameter | Parameter introduction | First generation | Second generation |
Figure A and Figure B | Figure C | ||
(collision type) | (on the type) | ||
efficiency | Total performance - homogeneous overall effect | ? General performance | + higher performance |
Multi-Channel | Multi-channel - facilitates process amplification | ? Unfavorable amplification | + can zoom in |
No Angle | No corners - good for high viscosity and low blockage | + not easy to block | ? easy to block |
Multi-Stage | Multi-level - for enhanced performance | + Two levels of homogenization | ? only one level |
Adjustable | Adjustable - for optimized performance | + adjustable | ? fixed |
In general, equipment using the first generation of homogeneous cavities is less expensive, but homogeneous performance is not as good as the second generation. The equipment using the second-generation homogenizing chamber has excellent homogenization effect on the emulsion, but when dealing with high-concentration and high-viscosity materials, it is easier to block than the first-generation product, and the price is relatively high. Therefore, the final choice should be determined according to product requirements and overall cost performance.
