Development of dried fruit grading machine, increase the income of the majority of growers, and promote the sustainable development of the dried fruit industry to improve the level of development of the dried fruit industry in China will be of great significance. So on the basis of research on s dried fruit sorting machine at home and abroad , a new-type dried fruit sorting machine with high productivity, high processing quality low cost and low energy consumption--dried fruit cleaning and sorting machine of grid cylinder By reading the literature and learning experience from it,there are some improving enhancing on the details of the cleaning and sorting machine and its technical,to make it more suitable for production requirements and more adaptive.Then,in accordance with the design requirements,we select the parameters for dried fruit cleaning and sorting machine of grid cylinder,and according to the calculation of the known formula to determine the mechanicals all parts of the size, based on the size of various parts of the machinery we do the checking and selection of the parts.After all the work being done, we assembly forming the various parts in the design.Ultimately we have the machine that we needed.
