Vacuum Emulsifying Mixer Has a unique shear effect, has great advantages in the treatment of liquid mixing, oil and water emulsification, powder dissolution, dispersion homogenization, shear grinding and other aspects.
Vacuum Emulsifying Mixer The water phase and oil can be broken into fine particles when the same, and then the two phases can permeate and mix into a stable emulsion state, but also can be broken into an ideal particle size, so that the solid particles evenly mixed into the liquid, forming a stable suspension. Vacuum Emulsifying Mixer Shear action can affect the fineness of materials, thus affecting the production efficiency of products and the quality of finished products.
The factors that can influence Vacuum Emulsifying Mixer shear are:
Leaf sharpness, hardness, stator gap, relative motion speed of two cutting blades, allowable particle size, etc.
However, the sharpness, hardness, stator clearance and allowable particle size of the blade will not change, so the shear force is affected by changing the relative movement speed of the blade. The relative movement speed of the blade is shown as the circumferential linear velocity of the rotor. When the linear speed reaches a certain value, there will be a trend to block the flow, but the flow will become smaller, but the heat is still very high, which will make some substances aggregate and affect the mixing effect.
So the speed is not the faster the better.
We know that the real stirring speed is not the angular speed of the blender, but the linear speed of the stirring leaf disc.
Relationship between angular velocity (ω) and rotational speed (n): ω =2 π n
Relationship between linear velocity (v) and rotational speed (n): v= ω r=2 π nr
It can be seen that the influencing factors are mixing speed and diameter, which is also the reason for the higher speed of laboratory Vacuum Emulsifying Mixer than industrial Vacuum Emulsifying Mixer. The processing capacity of laboratory Vacuum Emulsifying Mixer is small, and the physical size of the rotor is small in the diameter in order to adapt to the corresponding processing capacity.
To compensate for the effect of the small diameter on the linear velocity, it is necessary to increase the angular velocity of the rotor.
Therefore, when choosing Vacuum Emulsifying Mixer, it is necessary to combine the actual processing volume, and comprehensively consider the relationship between diameter and rotation speed size.
