| Vacuum flashing crystallizer, including crystallization tank, circulating pipe, a distributing pipe, forced circulation pump, inlet in the circulating pipe, the liquid inlet temperature than the crystallization tank mixture temperature is higher, so the liquid will direct rapid rise to the distributor, in the auxiliary vacuum equipment under the condition of mould pressure can be maintained in≤ 0.09MPa, under this condition solution boiling point below 50 DEG C, overflow cone meet rapid vaporization of liquid distributor, the vaporization and circular thrust under the dual role of material a fountain-shaped emission, in continuous operation in the process of moisture reduction, solution, concentration is increased, saturation state, the general case into the the solution is saturated, the evaporation process, the solution will have a large number of crystal precipitation, under the action of gravity sedimentation, after a certain time to open the outlet valve for discharging, or using the liquid continuous removal of crystal. Under normal circumstances can be continuously operated, while feeding side discharging, the adjustment of the operation condition, so that the mold had can control the particle size distribution of the product and the crystal slurry density means, the crystal size stability, the two mother liquor consumption, high production efficiency.

- Large capacity, small occupied area
The single equipment output can reach 100000 tons / year, large processing quantity, and the gap production equipment need sets, large occupied area.
- Energy saving
A, the use of raw materials own heat for two evaporation, no need the heat energy.
B, ordinary mould with cooling crystallization method, consume a large amount of refrigerant and power, the device in a simultaneous evaporationPlay a role in cooling without energy consumption.
C, general mold in the tank is provided with stirring, and the device utilizes the vaporization of the liquid and the material temperature difference power forming flow
- Dynamic thrust saves the stirring power.
- Simple operation, easy control
Upper crystallizer for vaporization zone, lower crystallization subsidence area, coarse grain is discharged from the bottom, fine grain through the circulating pipe circulation grew up, make grain uniformity, stability, and can be controlled in a certain range of crystalline grain size.
Low cost, less investment, only 40% of investment in equipment for batch crystallization
- Low operation cost
Due to the production process only a small amount of electric energy, no transmission parts and low operation cost.
