Automated system for classifying and flipping coconut copra Tie khda:

Coconut copra, copra classifying, copra flipping, copra turn over
ABSTRACT
Recently coconut copra and products from coconut copra are used in many food processing and medical industries. However, peeling the brown skin of coconut copra is often performed manually before the copra is sent to the next processing stage. This brown skin removal requires much time and labor; and is of low productivity. To tackle these issues, this research aims to design an automated system for classifying the black and white copra surfaces and flipping the white copra surface up for the next automated process of removing the brown skin of coconut copra. The requirements of the system are continuous operation, easy operation and repair, and ease for research work and application. Experimental results showed that the system was capable of automated classifying and up- flipping the white coconut copra surface at 600 kg copra per hour with 90% success rate for the most common copra size. These preliminary results indicate that the system can be further improved for higher productivity and suggests the development of a coconut peeling machine to increase the productivity of coconut copra processing, the value and quality of products from coconut copra.
