Abstract

The solar drying method consists of removing gartially and non-bound water with a small impact on the chemical structure and compositions, thus reducing the mass and minimizing the risk of numerous transformations. Taraxacum officinale leaves are well-known in the fields of pharmacology, herbal medicine, and traditional soft drinks. Since it is a seasonal plant, plants from these regions have become an indispensable element after drying and storing. The objective of this paper is to determine both total and specific energy consumption of the hybrid solar convection dryer in drying Taraxacum officinale leaves. The paper investigates the energy analysis of the leaves of Taraxacum solar drying, which includes the investigation of the impact of the aerothermal parameters’ variations: 4 temperatures (50, 60, 70, and 80°C) and 2 drying airflows (150 and 300 m³ h^–1) on the specific energy utilization in the drying process. Furthermore, this work studies the thermal efficiency as well as the energy efficiency of the solar dryer which gives room to maximize the performance of the dryer chamber. The results indicate minimal values of total energy consumption are achieved at higher temperatures and airflow rates. The findings reveal that lower total energy consumption is achieved at higher temperatures and airflow rates. Moreover, the study delves into thermal efficiency and energy efficiency, highlighting a thermal efficiency of approximately 5.58% at lower temperatures 50°C.

混合强制对流太阳能干燥器下蒲公英叶的能源性能探索

摘要太阳干燥法是在对化学结构和成分影响较小的情况下，去除部分和非结合水，从而减少质量并最大限度地降低多次转化的风险。蒲公英叶在药理学、草药和传统软饮料领域享有盛誉。由于它是一种季节性植物，这些地区的植物在干燥和储存后已成为不可或缺的元素。本文旨在确定混合式太阳能对流干燥机在干燥蒲公英叶时的总能耗和具体能耗。本文研究了蒲公英叶太阳能干燥的能耗分析，其中包括气温参数变化的影响：4 种温度（50、60、70 和 80°C）和 2 种干燥气流（150 和 300 立方米/小时）对干燥过程中特定能量利用率的影响。此外，这项工作还研究了太阳能干燥器的热效率和能效，这为最大限度地提高干燥室的性能提供了空间。结果表明，在温度和气流速率较高的情况下，总能耗值最小。研究结果表明，温度和气流速率越高，总能耗越低。此外，研究还深入探讨了热效率和能源效率，结果表明，在温度较低的 50°C 时，热效率约为 5.58%。
