Oleaster's emerging applications in the food and pharmaceutical industries are due to its anti-cancer and pain-relieving properties. Green extraction methods are crucial to ensure drug compatibility to eliminate unwanted substances. This study focuses on the single droplet drying method to simply mimic a spray dryer, investigating how the drying medium controls droplet evolution into particles. Experiments were conducted with low-fibrous oleaster extract at various initial solid concentrations and ambient temperatures (100 °C, 150 °C, and 200 °C). This paper also delves into the influence of temperature on droplet morphology evolution, impacting the final particle's characteristics. The droplet diameter exhibits intricate behavior, involving normal evaporation, abrupt shape, and size changes, and concluding in a sticky solid state. Moreover, the drying process duration extends with higher initial droplet concentrations. The findings recommend using 150 °C and 200 °C as favorable drying temperatures, resulting in raspberry-like particles at high temperatures and shedding light on the oleaster extract drying.

油橄榄 (Elaeagnus Angustifolia L.) 低纤维提取物粉末:干燥动力学分析

油酸酯在食品和制药行业的新兴应用得益于其抗癌和止痛特性。绿色提取方法对于确保药物相容性以消除不需要的物质至关重要。本研究重点关注单液滴干燥方法,以简单地模拟喷雾干燥器,研究干燥介质如何控制液滴演变为颗粒。在不同的初始固体浓度和环境温度(100°C、150°C 和 200°C)下使用低纤维油橄榄提取物进行了实验。本文还深入研究了温度对液滴形态演化的影响,从而影响最终颗粒的特性。液滴直径表现出复杂的行为,包括正常蒸发、突然形状和尺寸变化,最后形成粘性固态。此外,干燥过程的持续时间随着初始液滴浓度的升高而延长。研究结果建议使用 150 °C 和 200 °C 作为有利的干燥温度,在高温下产生覆盆子状颗粒,并为油酸酯提取物的干燥提供线索。
