What is vacuum emulsifier mixer?

RB vacuum emulsifier mixer, also called vacuum emulsifier machine, is a complete vacuum mixer system for the manufacture of viscous emulsions and suspensions in the cosmetic, pharmaceutical, food and chemical industries. It’s especially suitable for making big and continuous batches of cream and emulsions.

What is vacuum emulsifier mixer made of?

RB vacuum emulsifier machine is usually made of main emulsion mixer, oil phase mixer, water phase mixer, vacuum system, materials circulation system, heating and cooling system, temperature control system, electrical control panel etc.

The main emulsion machine is composed of a high shear inline homogenizer mounted outside the vessel horizontally and one frame agitator. Pipes are connected from the discharge valve to the inlet of the homogenizer and from the outlet to the top edge of the vessel body. The inline homogenizer consists of one three-layer toothed rotor and one two-layer toothed stator.

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 emulsion blender only.

How does vacuum emulsifier machine work?

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

The left part of the impellers move the cream upwards and the right part move it downwards. Because of the two opposite forces by the impellers, 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 production vacuum emulsion mixer is the inline high shear mixer (emulsifier) which consists of one three-layer toothed rotor and one two-layer toothed stator. The design is different from the batch homogenizer in RS series vacuum emulsifying mixer and is better for making cream with circulation.

The ABB or Siemens motor rotates at the speed of 3000rpm and drives the rotor to rotate up to 3000rpm producing strong suction force.

The materials go into the rotor from inlet 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. 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.

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 oil and water phase mixers to the main vacuum emulsion blender. The small quantity perfumes are also sucked by vacuum to avoid dust.

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