Background
Currently, a known high-shear dispersion emulsification mixing device for fluids is a high-shear dispersion emulsification mixer consisting of a stator/rotor and a driving mechanism. The fluid is treated by a high-shear dispersion emulsification mixer, and uniformly mixed solution, emulsion, suspension and gel can be obtained.
However, many materials in modern food, pharmaceutical, bioengineering, chemical, etc. fields are characterized by high viscosity non-newtonian fluids, and a large amount of powder or solid lumps are added during the process of dispensing the high viscosity materials. The combination of a high shear dispersion emulsion machine and an anchor stirrer is one of the more applied technologies in the related industries at present. However, the bottleneck of the method is the complicated equipment, the installation position is large, and the sterile working condition is difficult to satisfy! The existing related equipment at home and abroad has the following defects:
⑴ high shear dispersing emulsifying mixer can meet the mixing requirement of Newtonian fluid, while non-Newtonian fluid treated alone can cause uneven mixing!
⑵ the larger the viscosity of the material, the longer the retention time of the fluid in the working head of the high-shear dispersion and emulsification mixer due to the fluid viscosity, and the local rapid temperature rise of the material due to the conversion of the mechanical energy into heat energy under the shearing action of the stator and the rotor, which affects the quality index of the product.
⑶ the power consumption per unit volume is relatively large due to the limited impeller flow of the high shear dispersing emulsifier, which is usually 8kw/m3 based on water.
Therefore, the updating and upgrading of the high-shear dispersing and emulsifying machine becomes a key for meeting the mixing requirement of the non-Newtonian fluid, and provides more efficient mixing equipment for the fields of pharmacy, fine chemical engineering, food, new materials and the like.
