APV homogenizerIt mainly consists of a plunger pump and its combined pump body and homogenization valve. The function of a plunger pump is to suck liquid materials of a certain viscosity into the pump body and pressurize the materials. Pressure regulating device is a device that allows materials to pass through a homogenization valve at a specific pressure. Homogenization "refers to the process of refining and uniformly mixing materials in a homogenization valve.
APV homogenizerWorking Principle:
The precise fit between the rotor and stator, the claw structure of the working head (rotor and stator forging manufacturing), bidirectional suction, and high shear efficiency.
The intermittent high shear dispersing emulsifying homogenizer generates high-frequency, strong circumferential tangential velocity, angular velocity and other comprehensive kinetic energy through the high-speed and smooth rotation of the rotor
Efficiency; Under the action of the stator, a strong and reciprocating hydraulic shear, friction, centrifugal extrusion, liquid flow collision and other comprehensive effects are formed in the reasonably narrow gap between the stator and rotor. The material works in a cyclic manner in the container to obtain the product.
APV homogenizerMain advantages and disadvantages
Compared to centrifugal dispersing and emulsifying equipment such as colloid mills and high shear mixing emulsifiers, the characteristic of high-pressure homogenizers is that they have a stronger refining effect. This is because the valve core and seat of the working valve are tightly fitted in the initial position, but a narrow slit is forced out by the liquid during operation;
In order to achieve high-speed rotation and not generate excessive heat, there must be a large gap between the stator and rotor of the centrifugal emulsification equipment (compared to the homogenization valve);
Meanwhile, since the transmission mechanism of the homogenizer is a positive displacement reciprocating pump, theoretically speaking, the homogenization pressure can be infinitely increased, and the higher the pressure, the better the refinement effect.
The refining function of APV homogenizer mainly utilizes the interaction between materials, so the heat generation of materials is relatively small, thus maintaining the basic performance of materials unchanged.
It can quantitatively transport materials because it relies on reciprocating pumps for feeding.
High energy consumption.
There are many vulnerable parts and a large maintenance workload, especially under high pressure.
Not suitable for situations with high viscosity.
