Rapid Peanut Dryer

A quick drying process for peanuts is very important to maintain the quality of the peanuts and to extend its shelf life. Conventional drying processes often involve extended drying times, resulting in decreased productivity, increased energy consumption and a higher risk of quality deterioration. These challenges significantly impact peanut farmers, processors and the overall peanut industry. In order to overcome these problems, the Rapid Peanut Dryer is designed with a closed loop system aimed at achieving efficient and accelerated peanut drying. The closed system performance evaluation focused on key parameters such as drying time and energy efficiency. The closed system significantly reduced drying time compared to traditional methods due to controlled air flow and optimized heat distribution. The combination of airflow and heat effectively promotes the evaporation of moisture from the peanuts, making them dry quickly. In addition, the use of industrial electric fans (DC 12V) and electric heaters has improved energy efficiency, minimizing energy consumption while maintaining optimal drying conditions during the entire drying process of the peanut. The success of the system is augmented by the utilization of an Arduino Uno microcontroller which is essential for switching the fan, heater, and motor via a relay (5v DC), thereby optimizing system control and efficiency. The designed closed system provides an efficient and effective solution for drying peanuts quickly. The system significantly reduces drying time by incorporating controlled airflow and temperature control while preserving peanut shell life and nutritional value. The system will contribute to the advancement in groundnut drying process by minimizing the power consumption and provide practical insights in reducing the peanut drying time.
