[0002] A stirring head is a device used for mixing, dispersing or emulsifying liquid or semi-solid substances. It is usually mounted on the shaft of a blender or mixer and generates fluid dynamics effects through rotation. The working principle of the stirring head is based on the shear force, turbulence and circulating flow of fluid.
[0003] When the stirring head rotates, it will cut the fluid and generate shear force, which helps to break solid particles or liquid droplets and disperse them in another fluid. At the same time, the shape and size of the stirring head will affect the flow pattern of the fluid, thus affecting the mixing efficiency and quality. For example, some stirring head designs are designed to generate high shear rate to achieve rapid mixing and emulsification, while other designs may focus more on generating strong circulating flow to ensure uniform mixing throughout the container.
