Working Principle
Stirrer:
- The basic principle is to produce forced convection and mixing of liquid, gas or solid particles in the container through the rotation of stirring blades.
- During the mixing process, the stirring blades transfer mechanical energy to the fluid, forming shear force, squeezing force and diffusion force, etc., thus promoting the intermolecular interactions within the fluid to achieve the purpose of uniform mixing.
Homogenizer:
- Through the precision cooperation of rotor and stator, the rotor rotates smoothly at high speed, forming high frequency and strong circumferential tangential and angular velocities, so as to achieve homogenization effect.
- The sample passes through the homogenizing valve under high pressure, the sample is accelerated and the potential energy is converted under pressure, which generates shear effect, impact effect and cavity effect, thus realizing homogenization.
application
Stirrer:
- Widely used in various chemical, biological engineering, metallurgy and other industries.
- Specific application scenarios include mixing and preparation of chemical raw materials, processing and storage of crude oil resources, desulfurization and alcohol production process, fermentation tanks and cell cultures in bioengineering.
Homogenizer:
- Mainly used for tissue dispersion in biotechnology, sample preparation in pharmaceuticals, enzyme processing in the food industry, etc.
- They are also widely used in the pharmaceutical industry, the cosmetics industry, the paint industry and the petrochemical industry.
- In food processing, the homogenizer is often used to refine the material in the material of the liquid in the extrusion, strong impact and loss of pressure expansion of the triple role, so that the materials can be more uniformly mixed with each other, such as dairy processing using homogenizer to make the fat in the milk crushed to a finer size.
characteristics
Stirrer:
- There are various types of agitators, which can be selected according to different mixing needs and material characteristics.
- Stirrer usually have larger mixing capacity and stronger mixing ability.
Homogenizer:
- Homogenizers are usually characterized by high pressure and high speed, which can produce strong shear force and impact force.
- The processing effect of homogenizer is stable and repeatable, which can meet the demand of high-precision homogenization.
performance parameters
Stirrer:
- The main performance parameters include stirring speed, stirring power, stirring capacity and so on.
- The performance parameters of the agitator are usually selected according to the specific application scenarios and material characteristics.
Homogenizer:
- The main performance parameters include homogenizing pressure, homogenizing temperature, homogenizing times and so on.
- The performance parameters of the homogenizer have an important influence on the homogenization effect, and need to be precisely controlled according to specific application scenarios and material characteristics.
In summary, there are significant differences between agitators and homogenizers in terms of working principle, application scenarios, equipment characteristics and performance parameters. The choice of equipment depends on the specific process requirements and material characteristics.
