What is vacuum triple shaft mixer?

SZ vacuum triple shaft mixer, also called triple shaft mixer, is a multi shaft mixer for the production of viscous pastes and suspensions in the cosmetic, pharmaceutical, food and chemical industries. Hydraulic lifting system has more advantages of easy cleaning and maintenance. It’s quite suitable for making toothpaste.

What is vacuum triple shaft mixer made of?

SZ vacuum triple shaft mixer is generally made of vacuum mixing tank, hydraulic lifting system, heating and cooling system, temperature control system, vacuum pump system and electrical control panel etc.

The mixing tank combines in a single vessel one low speed anchor agitator and two high speed dispersers or batch mixers 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.

How does vacuum triple shaft mixer machine work?

During the mixing operation, the anchor agitator rotates clockwise slowly. With the attached teflon blades, the materials are scraped off the manufacturing 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 homogenizers for dissolving, homogenizing, and emulsifying.

Due to the two opposite forces by anchor agitator and dispersers or homogenizers, the toothpaste rolls over the vessel from top to bottom and back to top repeatedly. When the paste 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 and homogenizing. It also helps transfer the ingredients from the pre-mixing tanks. The powders are also sucked by vacuum to avoid dust.

Oil hydraulic pump is used to lift the cover of main vacuum multi functiona mixer. Safety devices are equipped to guarantee that the mixing part won’t start when the cover is lifted.
