What is vacuum mixer emulsifier?
BXZRJ-D vacuum mixer emulsifier is a vacuum mixer for the production of cream and lotion in the cosmetic, pharmaceutical, food and chemical industries. It’s the lab version of our BXZRJ vacuum emulsifying mixers and is suitable for customers to make test batches.
What is vacuum mixer emulsifier made of?
BXZRJ-D vacuum mixer emulsifier is generally made of main mixer emulsifier, oil phase mixer, water phase mixer, vacuum system, manual lifting system, tilting system for the main mixer emulsifier, heating and cooling system, temperature control system, electrical control panel etc.
The main mixer emulsifier consists of a high speed high shear homogenizator and counter-rotating centre agitator and wall scraper. The homogenizator, 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 agitator 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 emulsifier only.
How does vacuum mixer emulsifier 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 most important part of vacuum mixer emulsifier is homogenizator (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 is circulated inside the vessel and mixed, dispersed, emulsified and homogenized evenly.
Rotary impeller type vacuum pump (–0.08Mpa) is used 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 mixer emulsifier. The small quantity powders are also sucked by vacuum to avoid dust.
The cover of the main emulsifier mixer is lifted manually. The main mixer emulsifier is attached to a screw shaft with a hand wheel. When you rotate the hand wheel, the main mixer will go up and down.
