溶液结晶是从过饱和溶液中形成固体晶体,也称为“大量结晶”,因为它通常用于处理大批量产品。
这是一种非常有选择性的常见固液分离过程。它可以生产具有所需粒度的高纯度结晶产品,同时进一步提供回收净化溶剂的机会,其中最常见的是水。
溶液结晶非常适合大多数应用,尤其是大产能。使用不同的结晶器类型和它们之间的节能配置可以达到所需的粒径。
溶液结晶有三种基本类型的结晶器 - 强制循环 (FC)、导流筒折流板式 (DTB) 和流化床(奥斯陆)- 它们可以单独使用或组合用于:
工艺设备的选择和结晶操作的设计受许多产品和工艺特定参数的影响。
具体特征:
在全球范围内,溶液结晶设备每天处理数百万吨大批量产品,如糖、盐和肥料。根据结晶器的类型,可达到的粒径范围从微米到毫米。

The world's population is growing and with it demand for milk. Dairy is an essential component of many global diets. However, its production can be resource-intensive and impact the environment. GEA’s Christian Müller, Senior Director Sustainability Farm Technologies, sheds light on how technological innovations powered by GEA make milk production more efficient and profitable.
Engineering innovation often takes the form of incremental gains. Once in a while, it takes a leap. Case in point: The washing machine. Launched in September 2022, two new GEA software solutions are upending convention and delivering similarly dramatic efficiency gains in the resource-intensive process of membrane filtration.
