FAQ

What is a horizontal crystallization kettle?

A horizontal crystallization kettle is a device used to bring solutions to a supersaturated state and promote crystallization. Compared with a vertical crystallization kettle, it has:

Larger heat exchange area (horizontal layout, higher cooling efficiency)

The residence time of the crystal is more stable

It is more suitable for materials that are prone to sedimentation of crystals or have high requirements for stirring

It is more suitable for continuous industrial production

Typical application materials: sodium chloride, potassium chloride, nitrate, sulfate, organic salts, intermediates, etc.
Working process of horizontal crystallization reactor

The materials are fed into the horizontal reactor body
Start stirring to keep the solution uniform
Start jacket cooling or coil cooling
The temperature gradually decreases → the solution enters a supersaturated state
Nucleus formation → crystal growth
After reaching the target particle size, the crystal slurry is discharged
Enter the centrifuge for dehydration
The mother liquor can be returned to the system for further processing
Applicable to:
✔ Cooling crystallization ✔ Vacuum cooling crystallization ✔ Evaporation-crystallization combined process

FAQ

What are the differences between horizontal and vertical crystallization kettles?
+

Horizontal type is more suitable for materials with high viscosity, fast sedimentation and the need for stronger stirring, and it has better control over crystal particle size.
Can it be used for highly corrosive crystalline materials?
+

Sure. We offer materials such as TA2 titanium, 2205, and Hastelloy.
Can it be customized according to the customer's working conditions?
+

All parameters can be customized to non-standard specifications, including volume, material, stirring method, jacket structure, etc.
Can an evaporator be matched?
+

Supports combination with MVR, forced circulation evaporators and triple-effect evaporators.
