Engineering properties of the cashew nut in context of designing post-harvest handling and processing machinery

The determination of the engineering properties cashew nut is essential as basis for design and development appropriate optimum post-harvest handling processing machinery. present study examined physical, mechanical colour nuts (n = 100) at a moisture content 7.63% (wet basis) derived from Central Java, Indonesia. main characteristics included length, width, thickness, mass, volume, density. derivative consisted geometric diameter, arithmetic surface area, frontal transverse shape index, sphericity, bulk density, porosity. static friction, dynamic angle repose, compressive load (in four orientations). It was identified that Java dominant with small-medium size an average mass 5.42 ± 0.99 g. This thicker, but shorter in length than India, Nigeria, Ivory Coast. results stepwise regression analysis determined volume had most substantial relationship (R2 0.949), density highest correlation 0.968), porosity showed high true 0.997). and-dynamic repose occurred on plywood, lowest stainless-steel surface. In context designing cracking equipment, it recommended to provide impact parallel longitudinal axis orientation due minimum (reduce power requirement). Furthermore, L*, a*, b* coordinates were 35.988, 0.427, 1.718, respectively.
