The types of vacuum homogenizing emulsifiers produced are diversified. The homogenizing system is divided into upper homogenization, bottom homogenization and internal and external circulation homogenization; the mixing system is divided into one-way mixing, two-way mixing and spiral mixing; the lifting system is divided into single-cylinder lifting and double The cylinder is raised and lowered to meet the different production needs of cosmetic companies. Although the functional models of the vacuum homogenizing emulsifiers of cosmetic equipment manufacturers are diverse, the production procedures are basically the same.
How does the vacuum homogenizing emulsifier process chemical raw materials? The main procedures are as follows:
Pretreatment of cosmetic raw materials: The vacuum homogenizing emulsifier can set up a water and oil pot according to the actual situation of the customer, so that the cosmetic raw materials can be heated or cooled in the water tank and oil tank, and a pretreatment is performed first.
Vacuum suction: the pre-processed cosmetic raw materials in the water-oil pot can be sucked into the emulsification pot through the conveying pipeline under vacuum for stirring and mixing reaction.
Cooling and heating: Cooling is to insert low-temperature water in the interlayer with insulation layer to cool the cosmetic raw materials. The heating method is usually electric heating. The electric heating tube is used to heat the water or thermal oil in the interlayer of the emulsification tank to realize the heating of the cosmetic raw materials. Steam can also be used to heat the cosmetic raw materials.
Stirring: The agitator is designed with computer data. Generally, the central stirring is combined with the frame-type wall scraping stirring. Through the central stirring in the upper part of the emulsification tank, the PTFE scraper always caters to the shape of the stirring tank and sweeps away the sticky material on the wall At the same time, new interfaces are continuously generated for the taken materials, and then through the shearing, compression, and folding turbulence of blades and rotating blades, the cosmetic raw materials are continuously input into the high-shear homogenizing emulsifier.
Homogenization: After the materials are stirred and mixed, they flow down to the homogenizer below the pot body. Through the process of strong shearing, impact, turbulence, etc. generated between the high-speed rotating cutting wheel and the fixed cutting sleeve, the material is being sheared. It is cut in the slit and quickly broken into 200um-1um particles. Homogeneous stirring and paddle stirring can be used separately or simultaneously.
Defoaming: Since the emulsifying pot is in a vacuum state, the bubbles generated during the mixing process of the cosmetic raw materials can be removed in time, which greatly improves the quality of the processed materials. Discharge: The lid of the emulsification pot is an automatic lifting type, and the material discharging method can choose the emulsification tank body flip and tilt type, or the bottom valve pipeline can be used to discharge the material.
