半固态食品精准定量灌装技术与装备研究进展OA

As a typical non-Newtonian fluid,semi-solid food has complex rheological properties such as high viscosity and thixotropy,making the stability and accuracy of its filling process highly sensitive to fluctuations in key parameters such as material viscosity,solid particle distribution,and internal flow field parameters.Therefore,in-depth analysis of the filling process mechanism and the development of corresponding high-performance equipment for precise quantitative control has become the research focus in this field.The research progress of semi-solid food filling technology and equipment is systematically reviewed from the aspects of filling mechanism,methods,process simulation,and intelligent control.In response to the current challenges of poor material compatibility and insufficient working stability,the future research directions are further clarified as enhancing the dynamic rheological monitoring,conducting in-depth research on multi-physical field coupling simulation,integrating the full-chain intelligent control system,and promoting the flexible upgrading of equipment.
