Impact Resistance of Peanut

In this work, impact resistance of whole pod peanuts was studied, depending on its descriptive physical properties. An apparatus was designed and fabricated to realize this goal experimentally. In the experiment, a sufficient number of peanuts from each type supported on different materials underneath were struck by various materials in different configurations. The conditions of kernel and peanut shell were then recorded. The raw experimental data were processed by means of a developed computer program to evaluate the shelling percentage versus dynamic pressure, energy at impact, dynamic load, impact velocity, and dynamic deformation. Results showed that use of an iron grate in a shelling machine provided the most suitable material condition for the effectiveness of the impact method.
