An Engineering Study and Analysis of the Factors Affecting Evaporation Rate Under the Vacuum Drying Process

As a drying process is an essential key process for pharmaceutical processing of traditional Chinese medicine, a systematic study of processing and engineering technology was carried out. Based on the fundamental research on factors affecting the water evaporation rate of the vacuum drying process, the laws of the vacuum drying process were explored, and basic technical support was provided to the vacuum drying process research and facilities development. According to the characteristics of different stages of the process, appropriate technical measures were taken to provide a foundation for achieving a continuous process of vacuum drying.
