Abstract

Eggs are the main raw material food sector in Malaysia. Conventionally, separation of eggs by its grade has been done manually which consume the slower process. An Automatic Egg Grading Machine was developed by using spinning wheel methods to overcome the conventional grading process. Eggs can be divided into seven grades, which is grade AA, A, B, C, D, E, and F. This machine is used a hightech fibre sensors to detect the egg grading operation according to their height. The use of this sensor because this lens can maximizes the light emission efficiency, resulting in a tremendous improvement in the sensing range and the whole system is controlled by using a PIC microcontroller. The hardware is designed based on turning wheel concept. The input to the PIC is a limit switch used to initiate the movement, while the output is DC motor that will spin the wheel and stops at the respective grade position. This machine is to facilitate separation of grade eggs, accelerate the separation of eggs and reduce the use of human resources.
