Abstract

To conduct the study , the cedar nut was placed between two parallel panels, which determined the splitting force, deformation, power and hardness required to start reflecting the nut. The tests were carried out at the nut moisture values of 5.4, 11.9, 19.1, 23.6 and 30.1% and in two forms of nut arrangement (vertical and horizontal). In the first case, the cedar nut was positioned vertically, the large axis of the nut was parallel to the loading direction. In the following case, when loading horizontally, the large axis of the nut was perpendicular to the loading direction. The physical characteristics of the nut and the kernel were determined, i.e. weight, dimensions, average geometric diameter, sphericity, outer surface area and shell thickness. The vertical and horizontal load directions required to start chipping cedar nuts decreased with increasing humidity from 714.1 to 220.3 N and from 521.4 to 249.9 N. Then we came to the conclusion that the deformation at the reflection site and the power required to separate the cedar nut shell decreased with increasing humidity under load in the vertical and horizontal directions. The hardness of the nut decreased with increasing humidity, and this decrease continued until the moisture content in the vertical direction of the load reached 23.6%. In particular, when loading in the horizontal direction at any humidity, there was always a tendency for the nuclei to disintegrate. The results provide useful data for use by engineers in designing a machine suitable for cracking cedar nuts.
