Detailed working principle of high shear emulsifying machine
Release time:
2022-03-10
The high-shear emulsifying machine is the impact and shearing force generated by the mechanical action, so the shear rate is high and the shear force is strong. Under the action of the centrifugal force generated by the rotor, the material is injected from the radial direction into the narrow and precise gap between the rotors. The static position, because the material is subjected to centrifugal extrusion, impact and other effects at the same time, makes it disperse, mix and emulsify.
High shear emulsifying machineDetailed working principle
The high-shear emulsifying machine is the impact and shearing force generated by the mechanical action, so the shear rate is high and the shear force is strong. Under the action of the centrifugal force generated by the rotor, the material is injected from the radial direction into the narrow and precise gap between the rotors. The static position, because the material is subjected to centrifugal extrusion, impact and other effects at the same time, makes it disperse, mix and emulsify.
The working principle of high shear emulsifying machine;
1. A emulsification: after the material is sucked into the working chamber of the emulsifying machine, under the action of centrifugal force, the stator is reintroduced from the radial direction, and the centrifugal force, extrusion, shearing and other forces are realized in the precise and narrow gap between the rotors, so that the material is emulsified first.
2. Suction: high-speed rotating rotor produces a strong centrifugal force, used to work from the head of the feed area of the suction chamber.
3. Extrusion: The linear speed of the outer end of the high-speed rotating rotor is very high, greater than 15 m/s, higher than 40 m/s, and the uniformly emulsified material is extruded from the stator slot.
4. Continuous circulation: the material is continuously squeezed under the action of radial force, and it is repeatedly circulated when it encounters the resistance of the inner wall of the container. After countless cycles, the complete process of dispersion, homogenization and emulsification is completed.
High shear emulsifying machineIt can be used in conjunction with an in-line emulsion pump, and materials suitable for the performance of the high-shear emulsifier can be selected to produce qualified high-quality products.
Introduction to the performance of high shear emulsifying machine
Emulsification is the role of a liquid evenly dispersed in another immiscible liquid through tiny droplets. This is the interfacial phenomenon of emulsions. Two immiscible liquids, such as oil and water, are divided into two layers in a container. The oil with low density is in the upper layer, and the water with high density is in the lower layer.
High shear emulsifying machine is a rapid and uniform distribution of one or more phases into another continuous phase, but under normal circumstances, each is insoluble in each other. Due to the high tangential velocity generated by the high-speed rotation of the rotor and the strong kinetic energy brought by the high-frequency mechanical effect, the material is subjected to strong mechanical and hydraulic shearing, centrifugal extrusion, liquid layer friction, and impact tearing in the narrow gap between the stator and the rotor. The combined effect of turbulence. Under the joint action of the corresponding mature technology and the right amount of additives, the liquid phase and the gas phase are evenly and finely dispersed and emulsified, and the stable product is finally obtained through high-frequency circulation.
High shear emulsifying machineIt has a very important influence on the Z-final effect of emulsification.
High shear emulsifying machine is a kind of grinding, emulsifying and homogenizing equipment installed at the bottom of the reactor. It is generally used in conjunction with vertical emulsifying machine, pipeline emulsifying machine and other equipment, which can more effectively solve the problem of grinding and emulsification of sediment at the bottom of the reactor that cannot be solved by other equipment.
In the emulsification process of the high-shear emulsifying machine, the emulsification efficiency of the Z end depends on the emulsification time and the stirring speed in the emulsification process. It should be said that they have a very important influence on the emulsified Z end fruit.
