Design and experiment the tooth shape to split the coconut’s skin and fibrous husk

Abstract

The coconut tree is one of the key economic trees of Southwestern Vietnam. The products made from fibrous husk bring local economic potentials such as coir silk, coir carpet, coir pots, and coco peat. The process of separating the coconut’s skin and fibrous husk by method traditional much time and has potential risks of the occupational accident. So, it is necessary to overcome the stage of peeling by fabricating the coconut’s skin and fibrous husk separator for coir production. The paper presents theoretical calculation and the split tooth shape simulation compared with actual experiments. Calculating and experimentation the required load and torque moment on the separating shaft and the split tooth shape ensures the ability to separate the diverse shells of natural ripe coconuts to dried coconuts.
