What is the core component of high-speed dispersion vacuum emulsifying machine

Release time:

2019-07-04

The core element of the high-speed dispersion vacuum emulsifying machine is a pair of intermeshing rotor and stator. The periphery of the rotator is provided with the same number of slender cuts. When the rotor rotates at high speed, a large centrifugal force is generated, which causes the material to be processed to be ejected from the elongated slits (slits) of the rotor. And under the joint action of the stator, the material to be processed is subjected to two forces: the positive force that forces it through the slit and the resistance that prevents it from passing. Repeating this process at high speed will inevitably produce high-frequency pressure waves. At the same time, when the processed material is ejected from the slit, it is also subjected to the shearing effect of the slit, as well as the relative movement of the rotating stator.

Repeating this process at high speed will inevitably produce high-frequency pressure waves. At the same time, when the processed material is ejected from the slit, it is also subjected to the shearing action of the slit and the rotating shear force generated by the relative movement of the rotating stator.

To sum up, the processed material produces repeated compression and expansion effects under the action of high-frequency pressure waves, and at the same time is strongly affected by slit shear force and gyratory shear force, so that the processed material has a strong dispersion, emulsification and homogenization effect.

Features introduced:

Assembly and disassembly is simple and easy to clean, so it is suitable for frequent replacement of material varieties and strict food hygiene requirements.

The rotor is light in weight, small in moment of inertia, and suitable for high-speed rotation, so it can be processed with small equipment for large capacity.

A wide range of materials from low viscosity to high viscosity can be handled.

Because of its self-priming ability, it can use high-level feed when dealing with low-viscosity materials; but pumping is required when dealing with high-viscosity materials.

Comparison with colloid mill:

Like colloid mill, high-speed dispersionvacuum emulsifying machineIt is also a centrifugal device, so its flow rate is not constant, and it changes greatly with the change of material viscosity, outlet resistance and feed pressure. Compared with colloid mill, its advantages are:

a) The rotor is very light, suitable for large diameter and high speed, so that it is easy to make large flow and high power equipment.

B) The meshing size of the rotating stator is very short, the material passing resistance is small, and the energy consumption is reduced.

c) The rotating stators can be easily connected in series, so that the material can be used multiple times when passing through the equipment, thereby enhancing the thinning effect, while the colloid mill has only one pair of rotating stators.

d) It relies on the combined action of high-frequency pressure wave and slit shear force, so the stator has little effect on the thinning (homogenization) effect under general wear.

e) It can produce strong self-priming ability and is easy to connect with the pipeline for continuous operation.

f) The assembly and disassembly of the rotating stator is more convenient than that of the colloid mill. However, when dealing with hard large particle materials, the effect of the equipment is obviously not as good as that of the colloid mill.
