People gradually to fine processing of things, and pay attention to its quality. At the same time, in order to ensure food safety, people gradually put some food nutrition is not easy to come into contact with the rich or part to remove harmful substances, in this case, the separation machinery operation and gave birth to some things. Tomato pulper is one of them. In daily life applications, tomato pulper is mainly the tomatoes or similar fresh fruit pulp and peel or pulp and Hu separation, so as to achieve the fine processing, has the choice of the purpose of eating. The tomato pulper in ordinary life the application is more and more widely, more and more important in peoples life. But from its own design and organization, due to the lack of standards and technical specifications to depend on, so more and more depend on the existing enterprise information to carry on the design. This limits its development to a certain extent. This graduation design is in this context, based on some existing beater on the market research and in-depth research, by understanding its internal structure and basic parameters, design a practical, economic and security of tomato beater.
