Process principle:

The operation of isohydric fluidized bed crystallizers is generally similar to the operation of similar evaporative crystallizers, but the formation of crystals here occurs due to supercooling of the solution relative to the saturation point.

To create the best process conditions, isohydric crystallizers are usually installed in cascades, and their design features allow them to be used in combined circuits together with evaporators, creating high energy efficiency systems with reduced operating costs.

We offer simple designs - cooling reactors with mixing devices of various types, and more complex ones, for example, isohydric fluidized bed crystallizers. Depending on the specific task, both surface and vacuum cooling can be implemented in these devices.
