When it comes to vacuum emulsifying machine, many people may feel very unfamiliar with it. But our daily necessities are all related to this!
Vacuum emulsifying machine are mainly used in detergents, cosmetics, biological medicine, food industry, coatings and inks, printing and dyeing auxiliary, petrochemicals, printing and dyeing auxiliaries, paper industry, pesticides and fertilizers, plastics and rubbers, power electronics, other fine chemicals, etc.
Vacuum emulsifying machine refers to the material in the state of vacuum, the use of high-shear emulsifier to efficiently, quickly and evenly distribute one part or multiple parts to another part, and under normal conditions, each phase (such as oil part and water part) Are mutually incompatible. It uses the strong kinetic energy brought by the machine to make the material in the narrow gap between the stator and the rotor withstand hundreds of thousands of hydraulic shearing, centrifugal extrusion and impact tearing every minute. The dissolved phase is uniformly dispersed and emulsified in an instant under the combined action of the corresponding mature technology and appropriate amount of additives. After high-frequency cyclic reciprocation, a bubble-free, delicate and stable high-quality product is finally obtained. The equipment has the functions of rapid homogenization, heating and cooling and vacuum degassing, and has the advantages of good homogenization and emulsification, good sanitary conditions, high thermal efficiency, reliable electrical control, stable operation, convenient operation and maintenance, and low labor intensity. It is an ideal equipment for the production of creams, creams and honey cosmetics, and can be used for the production of related products in the pharmaceutical, food, and fine chemical industries with high viscosity materials.
Common vacuum emulsifying machine are mainly composed of pretreatment pot (water pot and oil pot), emulsification mixing main pot, vacuum system, mixing system, heating system, temperature control system, cooling, electrical control system, operation platform, etc. The materials in the water pot and the oil pot are fully dissolved and then sucked into the main pot by vacuum for mixing and homogenizing emulsification.
After the materials are mixed and reacted by heating and stirring in the water pot and oil pot, they are sucked into the emulsification pot by the vacuum pump, and stirred through the center of the upper part of the emulsification pot. The PTFE scraper always caters to the shape of the stirring pot, sweeping away the sticky materials. , So that the scraped material continuously produces new interfaces, and then through the cutting, compression, and folding of the blades, it is stirred and mixed and flows down to the homogenizer below the pot body. The materials are then fixed and fixed by the high-speed rotating cutting wheel. During the process of strong shearing, impact, turbulence, etc. between the cutting sleeves, the material is cut in the shearing seam and quickly broken into 200um-0.2um particles, which are sent to the upper part of the pot through a specific pipe to make the material Circulating homogenization, the material at the bottom of the pot is pumped to the upper part of the pot, and the material originally at the upper part sinks, so as to achieve the effect of full homogenization and emulsification. Because the emulsifying pot is in a vacuum state, the bubbles generated during the mixing process of the material are drawn away in time. Vacuuming is used to prevent bubbles from being mixed into the products during the mixing process, so as to ensure that high-quality products with luster, fineness and good ductility can be manufactured.
The industries involved in vacuum emulsifying machine, such as the daily care industry, biological medicine, and food industries have strict quality inspection requirements for hygiene, and the design of the vacuum system is also extremely strict. A common vacuum requirement is vacuum degassing. The entire process must be completed in a vacuum state to ensure no cell infection and extend the product shelf life. And use vacuum suction, especially for powder materials to avoid dust flying.
In the entire manufacturing process, the choice of vacuum pump is particularly important. The high-quality vacuum pump can ensure that the product gets a delicate and stable high-quality finished product during the emulsification process So, how should the vacuum pump be selected in this process?
