Design and Implementation of an Intelligent Sensor-Integrated Dehydration System for Sustainable Post-Harvest Preservation

Food is a fundamental necessity for human survival, and agriculture serves as the backbone of rural livelihoods, significantly influencing the Indian economy. However, farmers face numerous challenges, including limited mechanization, soil erosion, and unpredictable climatic variations. Among these, the drying of food products, particularly spices, under diverse climatic conditions remains a critical issue. Improper drying methods often compromise the quality of agricultural produce, leading to losses in both domestic and export markets. Ensuring the quality of dried products in terms of colour, flavour, and appearance while mitigating risks such as microbial growth, insect infestation, and contamination is essential for enhancing agricultural productivity and economic sustainability.
To address these challenges, this study proposes an innovative drying system designed to ensure the quality and safety of food products. The proposed dryer leverages advanced drying technologies and optimized environmental controls to maintain the integrity of agricultural produce. By integrating precise temperature regulation, airflow management, and contamination prevention mechanisms, the system ensures uniform drying while preserving the natural characteristics of the products. The methodology emphasizes energy efficiency and adaptability to varied climatic conditions, making it suitable for diverse agricultural applications.
The proposed drying system demonstrates significant improvements in the quality of dried products, ensuring enhanced color, flavour, and appearance. Experimental results indicate a substantial reduction in microbial growth, insect infestation, and contamination risks, thereby increasing the market acceptability of the produce. This innovation not only supports farmers in achieving higher economic returns but also contributes to sustainable agricultural practices. The findings underscore the potential of the proposed dryer to revolutionize food drying processes, ensuring quality preservation and boosting export opportunities, ultimately strengthening the agricultural economy.
