According to the different flow directions of heating steam and feed liquid, the operation flow of continuous evaporation crystallizer can be divided into countercurrent method, downstream method, cross-flow method and advection method. In addition to these four processes, other processes may be arranged according to the production situation. Sometimes in most of the evaporation, for example, every effect is not to create a effect after the secondary steam are introduced and used as heating steam, but will be part of the secondary steam used for preheating material liquid into the first effect of the derivation, or other has nothing to do with the evaporation of heating process, the rest is still after entering a valid heating steam
Product Usage: Pharmaceutical Crystallization Kettle Forced circulation evaporative crystallizer is a continuous crystallizer with crystal mud circulation. During operation, the feed liquid is fed from the bottom of the circulation pipe. After mixing with the crystallization slurry leaving the bottom of the crystallization chamber, it is pumped to the heating chamber.
