The selection of vacuum emulsifier for cosmetics equipment involves the following three steps:
Firstly, small-scale and pilot experiments can be conducted to obtain positive solution data. If you are preparing to develop a new product, first obtain the correct data in the laboratory through a cosmetics vacuum emulsifier. This can effectively avoid selection errors and further reduce the risk of production investment through pilot emulsification equipment.
The use of experimental data will be the key to equipment selection. The key to the dispersion effect of the cosmetics vacuum emulsifier is based on the rate at which the material reaches the shear zone and the mechanical energy transmitted to the material. Here, only the circumferential velocity of the rotor can be quantified. In the laboratory, the line velocity can be calculated based on the equipment speed when the material reaches the ideal state, and thus a suitable range can be selected in the industrial model.
Then, determine the issue of the processing capacity of the cosmetic vacuum emulsifier. In the selection table of industrial equipment, a reference processing capacity based on water is provided. In actual selection, the influence of factors such as material viscosity, specific gravity, solid content, and thixotropy should be comprehensively considered. However, the range of viscosity and thixotropy is difficult to define, so the actual processing capacity is often difficult to grasp. This requires good technical communication with engineers, and based on effective data and experience, come up with a realistic selection plan.
Finally, pay attention to the key points of selecting a vacuum emulsifier for cosmetics: determine the required results for suction and determine the process to be adopted;; Select according to the data obtained from the laboratory; List foreseeable working conditions, such as flammable and explosive, pressure resistance, vacuum pumping, corrosion resistance, and high temperature, requiring cosmetic vacuum emulsifiers to adapt to the special requirements of working conditions and surface treatment; In situations where there are many unforeseeable factors and the process is complex, a conservative selection method is proposed.
