vacuum emulsifying machineColloidal mill is a kind of grinding materials to achieve the purpose of homogenization, to obtain high-quality materials, in the food, pharmaceutical, chemical and other industries have been widely used. But what are the differences between the process performance and application range of these two kinds of equipment?? Which one should you choose when choosing? The following is a detailed introduction to homogenization.vacuum emulsifying machineThe difference between the colloid mill and the colloid mill, I hope to bring some help to everyone.

High shear lax emulsification is the efficient, rapid and uniform integration of one or more phasesThe process of (liquid, solid, gas) passing into another immiscible contiguous phase (usually liquid). In general, the phases are immiscible with each other. When external energy is input, the two materials recombine into a homogeneous phase. Because of the high tangential speed and the weak kinetic energy brought by the high-frequency mechanical effect caused by the high-speed rotation of the rotor, the material is subjected to intense mechanical and hydraulic shearing, centrifugal kneading, liquid layer conflict, impact tearing and turbulence in the narrow gap between the stator and the rotor, forming suspension (solid/liquid), emulsion (liquid/liquid) and foam (gas/liquid). So that the immiscible solid phase, liquid phase, gas phase in the corresponding sophisticated process and the appropriate amount of additives under the common effect, instant uniform precision lax emulsification, after high frequency cycle back and forth, finally get a stable high quality products.

The colloid mill is driven by a motor through a belt drive.(or called rotor) rotates at a high speed relative to the matching fixed teeth (or called stator). The processed material is pressurized by its own component or external pressure (which can be generated by the pump) to generate downward spiral impact force. When passing through the gap between the fixed and rotating teeth (the gap is adjustable), it is subjected to strong shearing force, conflict force, high frequency vibration and other physical effects, the material is effectively emulsified, scattered and destroyed, reaching the effect of superfine destruction and emulsification of materials.

From the principle, they all have grinding damage effect, colloid mill refinement effect is generally weakervacuum emulsifying machine, but it is more adaptable to materials.(such as high viscosity, large particles), so in many occasions, it is used in the front of the homogenizer may be used for high viscosity occasions. When there are more solid substances, colloid mill is often used for refinement.
