Enhancing Grape Drying Efficiency: A Thermo-Ecological Analysis of a Hybrid Solar Greenhouse Dryer

Abstract

Over the past few years, there has been a substantial increase in attention and notable interest in the utilization of solar energy for agricultural applications. This increased attention stems from the recognition of solar energy as a compelling and environmentally conscious alternative to conventional energy sources. Among the various applications, solar drying of crops has emerged as a promising method for preserving agricultural produce while minimizing energy consumption and reducing carbon emissions. In this study, our objective is to assess the thermoeconomic and ecological performance of a solar-electric hybrid greenhouse dryer specifically designed for grape drying. The proposed system integrates solar collectors, an electric heater, and a greenhouse structure to create a controlled and energy-efficient environment for grape drying. The assessment includes a thorough analysis of the thermal performance, energy consumption, and cost-effectiveness of the solar-electric hybrid greenhouse dryer. Additionally, an ecological assessment is performed to assess the environmental impact of the system, considering factors such as carbon emissions and sustainability. The findings of this study are expected to have a significant impact on the advancement of sustainable agricultural practices and the widespread adoption of renewable energy technologies in the field of food production. Moreover, the obtained results serve as valuable insights for designing and optimizing similar solar drying systems intended for different crops and geographical regions. By considering specific crop characteristics and local environmental conditions, researchers and engineers can develop efficient and customized solar drying solutions. This knowledge will ultimately enhance the effectiveness and applicability of solar drying technologies, facilitating sustainable agricultural practices across diverse contexts.
