Quality Improvement of Emulsions Dispersion in the Pulsation Homogenizer Using Computer Simulation
摘要
This work is devoted to researching technological equipment for homogenization. It has been found that the devices for obtaining finely dispersed emulsions, which exist today, need to be modernized to reduce the energy indicators of homogenization and increase the quality characteristics of the finished provision. As a result of the study, it has been established that the pulsating homogenizer allows for obtaining high homogeneity of the dispersed phase with low energy costs for the process. Although this study was conducted on a milk emulsion, the results can be used for other binary dispersion emulsions. The emulsion is dispersed in the pulsating homogenizer using the emulsion velocity gradient caused by the pulsating vibration of the shock piston. To calculate the hydrodynamic parameters of milk emulsion pumping speed, computer modeling was performed using software that allows for effective analysis of the homogenization process and has a special software package for this purpose - Ansys Workbench. With the help of computer modeling and calculations in ANSYS Workbench, the quality of homogenization due to processing milk in the pulsation homogenizer was determined. Experimental studies have shown that the average diameter of milk fat globules after homogenization in the pulsation homogenizer is 0.8 μm, which fully meets today's requirements.
