The speedy growth of the drink manufacturing produces sweet liquid demand, that is more and more powerful presently. Still, allure reaping science level is depressed, and accompanying the design of a long flow meager and thick bowed-dentition sweet liquid beating science, the raises animals’s work character is enhanced for one decline of source contaminations. This item details the active standard of the person who produces crops, the overall dispersion of beating materials, and force study of the beating facets to decide the makeup of the beating pieces. The four-sided test was completed activity, accompanying a infrequent–thick interphase beating beat as the research object, selecting operating speed, beating factor turning angle, and beating aspect framing angle as the test determinants, accompanying the entrainment misfortune rate and computer network beating rate as the amount indexes for the three-determinant, three-level test, and the use of Design-Expert to enact a analytical reversion model betwixt the determinants and two together signs, happening in the following reformed limits: when the operating speed is 1.0 m•s−1, the turning angle of the beating item is 80◦, and the rising angle of the beating detail is 45◦, the deficit rate of entrainment is 1.89%, and computer network beating rate is 95.53%. The machine’s design indexes are agreeing appropriate social principles and can meet the demand for automated reaping of sweet liquid.
