    • The present invention relates to a process for drying protein crystals starting from an aqueous protein crystal suspension, which comprises drying the protein crystal suspension in a centrifugal dryer, where the protein crystals, after they have been filtered off from the protein crystal suspension, are brought into contact with a drying medium which consists of a mixture of water and a nonaqueous solvent which is miscible with water in any ratio and which has a lower vapor pressure than water. In the process, a drying gas which has been moistened with water is advantageously used. The protein crystal suspension is advantageously converted into a fluidized bed for the purpose of drying.
    • 本发明涉及从蛋白质水溶液悬浮液开始干燥蛋白质晶体的方法,其包括在离心干燥器中干燥蛋白质晶体悬浮液,其中蛋白质晶体在从蛋白质晶体悬浮液中滤出之后被带到 与干燥介质接触,该干燥介质由水和非水溶剂的混合物组成,其与水以任何比例混溶并且具有比水更低的蒸气压。 在该方法中,有利地使用已经用水润湿的干燥气体。 蛋白质晶体悬浮液有利地转化为流化床,用于干燥。
