摘要
喷雾冷冻干燥技术近几年发展较快,在食品、医药、材料等领域都有广泛的应用,但是相应的喷雾冷冻干燥设备却发展较慢,在一定程度上限制了喷雾冷冻干燥技术的发展。本文首先介绍了喷雾冷冻干燥技术的原理与特点,及其应用现状,然后重点介绍了喷雾冷冻干燥设备的现状,分析了现有的各类喷雾冷冻干燥设备的优势和不足之处,并总结了近几年典型的喷雾冷冻干燥过程数学模型,探讨了喷雾冷冻干燥技术目前存在的问题和今后的发展方向。
Spray freeze-drying technology has developed rapidly in recent years, which has been widely applied in food,medicine, materials and other fields. However, the corresponding spray freeze drying equipment has developed slowly, which limits the development of spray freeze drying technology to a certain extent. This paper first introduces the principle and characteristics of spray freeze drying technology. Then it introduces the current situation of spray freeze drying equipment,analyzes the advantages and disadvantages of the existing spray freeze drying equipment, summarizes the typical mathematical models of spray freeze drying process in recent years, and probes into the existing problems and future development directions of spray freeze drying technology.
