摘要

The effectiveness and the performance of SAHs for drying fruits are examined in this article in different Moroccan regions renowned for fruit drying, each characterized by distinct climates: humid Mediterranean (Al Hoceima), semi-arid (Meknes), arid (Marrakech), and desert (Ouarzazate). The regions are known for drying figs, prunes, apricots, and dates, respectively. The study examines the efficiency of two thermal storage units: sensible and latent using granite and PCM, respectively. The investigation focuses on the ideal temperature needed for drying in each region. Using a C++ function, actual climate data for the warmest day of summer 2023 were inserted into the simulation software. The results show that in Meknes and Marrakech, it is strongly recommended to use the PCM as a storage unit to maintain the optimum temperature range for drying. However, in Al Hoceima and Ouarzazate, it is recommended not to use the PCM, as the temperature drops considerably during the day. The PCM extends the drying process by around 2, 3, and 4 h in Al Hociema, both in Meknes and Marrakech and in Ouarzazate, respectively. Besides, in terms of humidity and temperature, Meknes found to be the most suitable region in Morocco for drying.
