PerMix Jet Mixers Introduction
A jet mixer is used where homogenizing, dispersing, suspending, emulsifying, dissolving are required. Its advantages compared with a conventional agitator are free of aeration, no floating powder, no sedimentation, no additional baffles, no flow dead zones, and very high efficient that a small motor can keep large volumes in motion.
A jet mixer functions with its special designed stator/rotor system. The rotor is usually a turbine impeller, and the stator is a curved guide tube surrounding the rotor. When it works, the rotor generates a strong axial flow from the surface of the liquid, going through the stator tube and towards the bottom. In this manner, floating powder is drawn into the liquid, and sedimentation is lifted up. With many circulations, the total tank can be mixed and homogenized without dead zones.
There are four steps to describe the working principle :
Step 1. When the rotor runs at high speed (up to 3,000rpm @ 50Hz), strong vacuum is generated at its center. Liquid & solid above are drawn into the tube with the guidance of the deflector (stator).
Step 2. Centrifugal force leads the materials to the periphery. Liquids and solids are subject to intensive squeezing and milling at the precision-machined clearance between stator and rotor.
Step 3. For N agitator, materials are expelled out from the bottom of the tube back to the liquid body. For O agitator, a part of them will stand another intense hydraulic shear as they pass through the openings in the stator. Step 4. Fresh materials are continually drawn into the stator and rotor to maintain the mixing cycle in the tank.
Two Types of Jet Mixer :
- Top entry (open or closed vessel)
- Side entry
- Bottom entry
Jet mixers can be used in almost all branches of processing in the chemical industry, pharmaceutical productions, food industry and cosmetic products.
