[0002] With the development of food processing, more and more food processing has become automated. An emulsifier, also known as a shear mixer, uses a high-speed rotating homogenizer head connected to a motor to shear, disperse, and impact the material. This makes the material more delicate and promotes the blending of oil and water.

[0003] However, the existing shear mixer has a single function and can only perform emulsification and stirring. For food production companies, if they purchase a shear mixer separately to perform emulsification and stirring of materials, the efficiency is relatively low and the utilization rate is low. Production companies hope to have a stirring equipment that can not only stir ordinary materials, but also perform emulsification and stirring, so as to improve the utilization rate of the equipment. Moreover, production companies will also put forward requirements for the stirring efficiency of emulsification and stirring. Since ordinary emulsification and stirring equipment only performs emulsification and stirring through a shear stirring head, the stirring efficiency is relatively prioritized.
