What is emulsifying mixer?
BXZRJ-E emulsifying mixer is vacuum processing equipment for the production of cream and suspensions in the cosmetic, pharmaceutical, food and chemical industries. It`s the simplified version of our BXZRJ vacuum emulsifying mixers and is suitable for budget tight customers to make small batches.
What is emulsifying mixer made of?
BXZRJ-E vacuum emulsifying mixer is generally made of main emulsifier mixer, oil phase mixer, water phase mixer, vacuum system, pneumatic lifting system, tilting system for the main emulsifier mixer, heating and cooling system, temperature control system, electrical control panel etc.
The main emulsifier mixer consists of a high speed high shear homogeniser and counter-rotating centre agitator and wall scraper. The homogeniser, 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 emulsifier mixer only.
How does emulsifying 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 homogenising 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 emulsifier mixer is homogeniser (emulsifier) which consists of one high speed rotor and one holed stator. The rotor is driven by the 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 homogenised 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 homogenised uniformly.
Rotary impeller type vacuum pump (–0.08Mpa) is used to pull out the bubbles generated during mixing, dispersing and homogenising. It also helps transfer the ingredients from the oil and water phase tanks to the main emulsifier mixer. The small quantity powders are also sucked by vacuum to avoid dust.
The cover of the main emulsifier mixer is lifted pneumatically. You connect compressed air (≤0.4Mpa) to emulsifier mixer and operate it electronically.
