Design and Construction of a Microcontroller Based Palm Kernel Cracker

Abstract

The growing demand for palm kernel oil and its derivatives necessitates the development of efficient and cost-effective methods for palm kernel cracking. This paper presents the design and construction of a microcontroller-based palm kernel cracker, aimed at improving the traditional manual cracking process.  The proposed system utilizes a microcontroller unit (MCU) as the core control unit, providing precise control and automation for the cracking process. The design incorporates an optimized mechanical system that employs adjustable cracking blades and a rotating drum to ensure effective and consistent cracking of palm kernels. The microcontroller unit facilitates real-time monitoring and control of critical parameters, including cracking speed, pressure, and kernel separation. To enhance safety and productivity, the system incorporates sensors for detecting kernel presence and machine faults, allowing for immediate response and intervention. The microcontroller-based user interface provides operators with intuitive control and monitoring options, streamlining the operation and minimizing human errors. The performance of the developed palm kernel cracker was evaluated through experimental tests. The results indicate a significant improvement in cracking efficiency and consistency compared to manual methods. The proposed system offers the potential to enhance palm kernel processing efficiency, reduce labor costs, and increase overall productivity in the palm oil industry.
