Engineering Properties of Two Hazelnuts Varieties and Its Kernel Relation To Harvest and Threshing

Abstract

In this research, several engineering properties of two hazelnut cultivars (Palaz and Cakildak varieties) were determined and compared in terms of linear dimensions, mass, sphericity, surface area, projected area, true and bulk densities, porosity, repose angle, shell ratio, terminal velocity, rupture force, energy, deformation and drag coefficient. These properties are necessary for the design of much equipment for harvesting, processing, and transportation, sorting, separating and packing. Also, rupture force and deformations were determined which are the most discriminant parameters that can be used to describe the behavior under compression. In both cultivars, these values were also determined within the kernels.
