What is mixer homogenizer?
BXZRH-B mixer homogenizer is a vacuum mixing system for making viscous cream and lotion in the cosmetics, pharmaceuticals, food and chemicals industries. It’s the similar design of our BXZRH vacuum mixer homogenizer and is especially suitable for making big batches of cream and lotion with big quantity powders.
What is vacuum homogenizing mixer made of?
BXZRH-B vacuum homogenizing machine is usually made of main homogenizing mixer, oil phase mixer, water phase mixer, vacuum system, hydraulic lifting system, heating and cooling system, temperature control system, electrical control panel etc.
The main homogenizing machine is composed of a high speed high shear homogenizer mounted from the bottom of the vessel, wall scraper and two fixed propellers with holes. The bottom homogenizer consists of one three-layer toothed rotor and one two-layer toothed stator. There’s no external circulation pipe attached to the homogenizer. It’s internal homogenization only.
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 don’t take the oil and water phase mixers and keep the main homogenizing machine only.
How does vacuum homogenizing mixer work?
During the mixing operation, the outer 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.
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 emulsifying and homogenizing 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 machine 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 vacuum mixer homogenizers BXZRJ series and is much better.
The rotor is connected with homogenizing motor by a synchronous belt with the shaft ratio of 1:1.2. 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 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 openings of the stator. The cream runs along the inside wall upwards and then goes back to the center homogenizing head for internal homogenization.
The above two types of slow and high forces repeat and repeat. And the cream circulates inside the tank 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 mixer homogenizer. The small quantity perfumes are also sucked by vacuum to avoid dust.
Oil hydraulic pump is used to lift the cover of main vacuum homogenizing mixer. Safety devices are equipped to guarantee that the mixing part won’t start when the cover is lifted.
