Peltier Module Based Cooling System for Food Security and Reducing Post Harvest Losses with Temperature Regulation

Abstract

Global food security faces a critical challenge due to post-harvest losses of fruits and vegetables. In regions with warm climates and limited infrastructure, inadequate cooling and storage facilities lead to rapid spoilage. This is-sue demands an innovative solution, and a Peltier module-based cooling system offers a promising approach. By utilizing the Peltier effect, this system achieves energy-efficient and eco-friendly thermoelectric cooling. Unlike traditional refrigeration methods, it avoids the use of potentially harmful refrigerants, making it a sustainable choice. Integrated temperature and humidity sensors enable the system to monitor and adjust conditions within the cooling chamber in real-time. This ensures optimal preservation of various produce types. The system's potential impact on food security is substantial. By extending the shelf life of fresh produce, it can dramatically reduce wastage, allowing more food to reach consumers. This holds profound implications for small-scale farmers and vendors, particularly in areas with limited market access. The system's affordability and accessibility empower them to improve product preservation, boost their income, and contribute to greater food availability within their communities. Moreover, the portability and potential for off-grid operation using solar or alternative energy sources make it suitable for areas with unreliable electricity, further expanding its reach and impact.
