Oil and water phase mixing tanks for cosmetic cream making

https://ginhong.com/multi-shaft-mixer...

It's a short video of our 40/400L oil and water phase mixing tanks which will be used to work with a 500L vacuum triple shaft mixer customer bought in 2015 to make cosmetic cream.

The 400 liters water is equipped with load cells to weigh the water inside. A metering pump will be dosing water slowly and stably to 500L cream making machine.

What is vacuum triple shaft mixer without hydraulics?
SZ vacuum three shaft mixer is a vacuum multi shaft mixer for the production of viscous paste and suspensions in the cosmetic, pharmaceutical, food and chemical industries. It has similar design as SZ closed triple shaft mixer but with vacuum system. It’s also quite suitable for making toothpaste.

What is vacuum triple shaft mixer made of?
SZ vacuum three shaft blender is generally made of vacuum mixing tank, vacuum system, heating and cooling system, temperature control system, electrical control panel etc.

The mixing tank combines in a single vessel one low speed anchor agitator and two high speed dispersers or top entry batch homogenizers or combination of disperser and homogenizer.

Normally, this agitator is top installed at the center of the vessel for slow speed mixing and the high speed dispersers or top entry batch homogenizers are installed in the room between the shaft and outside wings of the anchor mixer.

The oil and water phase mixers have exactly the same construction. There’s a high speed disperser mounted from the top of the cover which helps dissolve the ingredients. Some customers will omit the oil and water phase mixers and keep the main vacuum muti functional mixer only. A powder mixer with helix ribbon usually works with the main mixer machine to handle the large quantity of powders.

How does vacuum triple shaft mixer work?
During the mixing operation, the anchor agitator rotates clockwise slowly. With the attached Teflon blades, the materials are scraped off the vessel wall and move upwards so they won’t always stick to the wall and burn.

The high speed dispersers are driven by ABB or Siemens motor and rotate at the speed of 1400rpm producing strong high shear force. The dispersers are even capable of shearing rubber chips etc rapidly to shorten the dissolving time significantly.

Dispersers are also replaceable with batch mixers for dissolving, homogenizing, and emulsifying.

Due to the two opposite forces by anchor agitator and dispersers or homogenizers, the paste rolls over the vessel from top to bottom and back to top repeatedly. When the toothpaste is completely mixed, the heat from the jacket is quickly transferred to every part through the inside wall.

Water ring type vacuum pump (–0.09Mpa) is powerful to pull out the bubbles generated during mixing, dispersing, emulsifying and homogenizing. It also helps transfer the ingredients from the pre-mixing tanks to the main three shaft mixer. The powders are also sucked by vacuum to avoid dust.
