| Abstract: | The specific heat of high moisture content farm products is one of the important parameters of thermophysical properties in designing farm products processing equipment. The BP neural network(BPNN) model of the specific heat of farm products with a high moisture content is established, and the calculated precisions between dual regression model and BPNN model are compared. The result shows that the calculated precision is higher for BPNN model than that for dual regression model. |
