The Effects of Morphological Development During Drying of Drops Upon Drying Rates and Loss of Highly Volatile Solutes

对干燥过程中颗粒形态的发展进行了实验研究，包括膨胀、破裂、凹陷和内部气泡的形成等现象。将调查干燥速度和高挥发性溶质的保留或损失。摄像机将被用来记录悬浮在中空陶瓷纤维上的液滴干燥的变化，并在中试规模的干燥器中进行。该项目将对了解喷雾干燥机最终干燥区域的过程产生影响。除了提高最终产品的质量外，本研究的目的是减少干燥过程中挥发性有机物释放对环境的破坏。预计该项目将提高对干燥的物理理解，在食品和化学加工中具有潜在的实际应用。

It is proposed an experimental study to the development of particle morphology during drying, including phenomena such as expansion, bursting, cratering, and formation of internal bubbles. The drying rates and the retention or loss of highly volatile solutes will be investigated. A video camera will be used to record changes of drop drying while suspended from a hollow ceramic fiber, and in a pilot scale dryer. The project will have impact on understanding processes in the final drying region of spray dryers. Besides the improvement of the quality of the final product, the research aims the reduction of the environmental damage caused by volatile organic chemical release during drying. It is expected that the project will lead to improved physical understanding of drying, with potential practical application in food and chemical processing.
