What is vacuum emulsification mixer?
BXZRW vacuum emulsification mixer is a vacuum processing unit for the manufacture of viscous emulsions and suspensions in the cosmetics, pharmaceuticals, food and chemicals industries. It’s especially suitable for continuously making big batches of cream and lotion.
What is vacuum emulsification mixer made of?
BXZRW vacuum emulsification machine is usually made of main emulsification 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 emulsification 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 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 mixer homogenizer only.
How does vacuum emulsification mixer work?
During the mixing operation, the frame agitator rotates clockwise slowly. With the attached Teflon blades, the materials are scraped off the vessel 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 vacuum mixer homogenizer is bottom homogenizer (emulsifier) which consists of one three-layer toothed rotor and one two-layer toothed stator. The design is different from the homogenizer in BXZRD vacuum emulsion mixer and is better with circulation.
The ABB or Siemens motor rotates at the speed of 3000rpm and drives the rotor to rotate up to 3600rpm 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 (–0.097Mpa) 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 emulsification machine. The small quantity perfumes are also sucked by vacuum to avoid dust.
