I. Main Types of Crystallizers
Evaporation Crystallizer: Increases solution concentration through solvent evaporation by heating until crystallization occurs.
2. Cooling Crystallizer: Achieves supersaturation of the solution by cooling
Condition, crystallize.
3. Reaction Crystallizer: Directly produces crystalline products during the chemical reaction process.
4. Vacuum crystallizer: Lowers boiling point under vacuum to achieve rapid crystallization.
Section II: Basic Structure of Second-Hand Crystallizers
·Vessel: Made of corrosion-resistant material (such as stainless steel) for containing solutions.
·Mixing System: Ensures uniform solution blending, preventing crystal precipitation. ·Heating/Cooling Unit: Controls temperature to regulate crystallization rate.
· Filtration or separation equipment: Separates crystals from mother liquor.
· Control System: Automated or semi-automated operation; some second-hand equipment may be outdated manual models.
