Characterising Thermal Behaviour of Smart Greenhouse Based on the Dehydration Performance

Abstract

The importance of optimizing dehydration processes in agriculture, particularly in seafood and fruit production cannot be overstated. Conventional methods reliant on human observation and susceptible to weather conditions often lead to inefficiencies and inconsistent product quality. This paper addresses these challenges by introducing a novel approach, a smart greenhouse system powered by renewable energy sources to enhance drying processes and product quality. By integrating renewable energy sources, such as photovoltaic panels, the system efficiently powers heating mechanisms, ensuring optimal drying conditions irrespective of weather fluctuations. Temperature sensors enable real-time monitoring and regulation of greenhouse conditions, while a hygienic design safeguards product safety and quality. Methodologically, the study rigorously examines the greenhouse system's design, sizing and thermal behavior, particularly in relation to the utilization of solar energy. Through detailed calculations and experimentation, the research explores variables including the impact of wind angle on heater fan operation, optimal exhaust fan placement and the correlation between wind speed and greenhouse temperature. The findings underscore the profound influence of greenhouse design and management on dehydration efficiency. Notably, the research elucidates the significance of proper environmental control in achieving consistent and high-quality dehydration outcomes. Furthermore, the alignment of results with existing literature on smart greenhouse systems and dehydration performance substantiates the study's contributions and insights. The findings not only advance scientific understanding but also lay the groundwork for further research aimed at refining and scaling sustainable dehydration practices in agriculture.
