What is the high shear emulsifying machine like? What are the functions?

Release time:

2022-04-30

The high-speed rotating rotor of the high-shear emulsifying machine is driven by the motor to rapidly and bidirectionally suck the materials at the bottom of the rotating kettle. The working area of the stator is subjected to strong mechanical movement and hydraulic shearing in a very narrow gap, so that the materials are sheared, torn and crushed, mixed and homogenized with the materials, and more effectively cooperate with the vertical emulsifying machine to complete the technological process of emulsification, homogenization, destruction and mixing reaction.

Next, let's talk about the high shear emulsifying machine.

When nonionic surfactants are used as emulsifiers in high shear emulsifiers, hydrophilic or lipophilic emulsifiers tend to dissolve in the oil phase. This method of preparing emulsions is known as the emulsifier-in-oil method. If fatty acids are used in the emulsion formulation, the fatty acids can be made soluble in the oil phase and the alkali soluble in water. When the two phases are mixed, a soap is formed at the interface, resulting in a stable emulsion.

The high shear emulsifier mixes the liquid in the emulsifier through an emulsifying impeller. The reason why the types and prices of emulsifying machines sold on the market are different is because of the different functions of the stirring paddle matched with the emulsifying machine. In the high-shear emulsification equipment, the new three-blade stirring equipment not only increases the contact surface between the impeller and the material, but also improves the mixing speed.

High shear emulsifying machineIt has the functions of high-speed mixing, dispersion, emulsification and dissolution, and can make two or more materials disperse and mix with each other to achieve a uniform state. It can also speed up heat transfer, mass transfer and chemical reaction, and has a good dissolution and emulsification effect on industrial additives such as sugar, milk powder and gum.

When the equipment is working, the high-speed shear emulsifying head of the high-shear emulsifying machine can generate huge rotary suction, which sucks the material directly above the rotor in a rotating manner, and then throws it to the stator at high speed. After high-speed shearing, collision and destruction between the rotors, the materials are gathered at the outlet and discharged. The anti-vortex baffle at the bottom of the tank converts the rotating force into the upper and lower stirring force, so that the materials in the tank are evenly mixed, and the powder is prevented from accumulating and agglomerating on the liquid surface, so as to achieve the purpose of hydration and emulsification.

High shear emulsifying machine is the rapid and uniform dispersion of one or more phases into another continuous phase, but in general, these phases are immiscible. Due to the high tangential speed of the high-speed rotating rotor and the weak kinetic energy generated by high-frequency mechanical action, the material is subjected to strong mechanical and hydraulic shearing, centrifugal extrusion, liquid layer friction, impact tearing and turbulence in the narrow open space of the stator and rotor.

High shear emulsifiers are particularly suitable for working at atmospheric, vacuum and positive pressure. It has the advantages of stable work, low noise, convenient and flexible cleaning, continuous use, ultra-fine dispersion, emulsified materials, etc. The rotor and stator of the working head of the high shear emulsifier are generally made of forgings, so they have good comprehensive mechanical properties. and high emulsification efficiency.

The shear head is composed of a rotor and a stator. The high linear velocity of the rotor and the weak kinetic energy generated by the high-frequency mechanical action make the material subject to shearing, centrifugal extrusion, liquid layer friction, impact tearing and turbulence in the open space of the rotor and the stator. Comprehensive effect, so as to achieve the effect of dispersion, grinding and emulsification.
