How does production homogenizing mixer work

- Oct 28, 2020-

During the mixing operation, the outer anchor agitator rotates clockwise slowly. With the attached  blades, the materials are scraped off the mixing tank wall and move upwards so they won’t always stick to the wall and burn.

 

At the same time the two fixed impellers keep still and give the materials a counterforce and drive the cream downward into the high speed homogenizing and emulsifying zone. The cream goes through the holes on the paddles and increases mixing effect.

 

Because of the two opposite forces by fixed impellers and wall scraper, the cream rolls over the vessel from top to bottom and back to top repeatedly. When the cream is completely mixed, the heat from the jacket is quickly transferred to every part through the inside wall.

 

The heart of vacuum homogenizing equipment is rotor stator homogenizer (or called emulsifier) which consists of one three-layer toothed rotor and one two-layer toothed stator. The design is different from the homogenizer in RS series production vacuum emulsification mixer and is much better.

 

The rotor is directly connected with homogenizing motor by flanges. The ABB or Siemens motor rotates at the speed of 3000rpm and drives the rotor to rotate at high speed producing strong suction force.

 

The materials go into the rotor from top opening of the homogenizer and are cut, sheared, emulsified and homogenized through the shear gap between the rotor and stator. Then they’re accelerated to jet out through the pipeline along the tangent of the rotor. The cream runs inside the external circulation pipe and goes back to mixing tank for the slow mixing or another emulsification and homogenization.

 

The above two types of slow and high forces repeat and repeat. And the cream circulates through the pipeline and is completely mixed, dispersed, emulsified and homogenized.
