| Abstract: |
| Using Luhua, Fuxihei peanut kernels and Silihong peanut kernels as the objects, the mechanical properties of peanut kernels under hydrostatic crushing were tested by MTS E45 electronic universal material testing machine. The effects of pressure velocity, pressure mode, pressure quantity of peanut kernels and peanut type on the crushing force of peanut kernels were studied. The results showed that the crushing force of peanut kernels was not significantly affected by the pressure velocity. The crushing force of peanut kernels under positive pressure was greater than that under lateral pressure and inclined 45 degrees pressure. The crushing force of Luhua peanut kernels under positive pressure was the largest, while that of Fuxihei and Silihong peanut kernels was smaller. The crushing force of Luhua peanut kernels was 1.39-2.56 times and 3.38-6.11 times under two-grain pressure and five-grain pressure as high as that under one-grain pressure. Therefore, in the design of the key components of peanut kernel crusher, the maximum crushing force of Luhua peanut kernel under positive pressure was selected as the design basis. |
