In the production process, certain components of its semi-finished products should be separated according to the different requirements of specific sensory and physical and chemical indicators. The tomato beater is suitable for the separation of many fresh fruits and vegetables. With the improvement of people's living standards, the role of tomato beaters in people's lives is becoming more and more important. For the beater, there are some defects in engineering design and use, such as unreasonable parameter selection. At present, the design of the beater is still based on the calculation of the empirical formula. In the empirical formula, the selection of many parameters is selected within a certain range based on experience. This makes the design of the beater lagging behind, and it cannot improve its design level and improve the performance of the product . In view of the poor use of fruit and vegetable juice processing equipment in our country at this stage, the resulting fruit and vegetable juices have rough quality and poor taste.
