Research and analysis of classification model based on the shape parameters of cashew nuts

The paper tried to build the classification model of cashew nuts and had analyzed the shape parameters of cashew nuts, and the paper concluded that there was a clear linear relationship between the length and height of cashew nuts and there was not a clear linear relationship between the length and thickness of cashew nuts or between the height and thickness of cashew nuts. Because of the restrictions of classification movement of cashew nuts, we could choose the length of cashew nuts to replace height of cashew nuts as key parameters of classification. Therefore, we could determine respectively three sizes of 18 mm, 28 mm and 42 mm as the length of long circular sieve of the classification machine. To solve the problem of the nonlinear relationship between thickness and length or height of cashew nuts, the paper analyzed the correlation between thickness of cashew nuts and breadth of long circular sieve. Finally the paper identified 19 mm width as long circular sieve.
