What is cosmetic mixer?
BXZRJ emulsifying machine is a vacuum processing unit for the production of viscous emulsions and suspensions in the cosmetic, pharmaceutical, food and chemical industries. It`s the most popular emulsifying mixers design in Asia and US.
What is cosmetic mixer made of?
BXZRJ emulsifying machine is generally made of main emulsifying mixer, oil phase mixer, water phase mixer, vacuum system, hydraulic lifting system, tilting system for the main emulsifying mixer, heating and cooling system, temperature control system, electrical control panel etc.
The main emulsifying mixer consists of a high speed high shear homogenizer and counter-rotating centre agitator and wall scraper. The homogenizer, centre agitator and wall scraper are all mounted from the top of the cover.
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 emulsifying mixer only.
How does cosmetic mixer work?
During the mixing operation, the outer frame 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 inner straight impeller rotates counter clockwise slowly and moves the cream downward into the high speed homogenizing and emulsifying zone.
Because of the two opposite forces by center agitator 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 emulsifying mixer is homogenizer (emulsifier) which consists of one high speed rotor and one holed stator. The rotor is driven by ABB or Siemens motor and rotates at the speed of 3000rpm producing strong suction force. The materials go into the rotor from both top and bottom 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 holes on the stator.
The above three types of slow and high forces repeat and repeat. And the cream can be circulated inside the vessel and mixed, dispersed, emulsified and homogenized evenly.
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 tanks to the main emulsifying mixer. The small quantity powders are also sucked by vacuum to avoid dust.
Oil hydraulic pump is used to lift the cover of main emulsifying mixer. Safety devices are equipped to guarantee that the mixing part won`t start when the cover is lifted.
