Working Principle:

The Continuous Crystallization Evaporator produced by Kaida Evaporation Crystallization Co., Ltd. is a highly efficient thermal utilization method commonly used in the production processes of the chemical and pharmaceutical industries. However, in actual production, one often encounters salts with solubility curves that change drastically with temperature (such as ammonium chloride, ammonium fluoride, etc.). When using multiple-effect evaporation, these salts tend to produce crystalline salts in each effect evaporator. If the crystalline salts in the evaporator are not promptly removed, it not only reduces the lifespan of the pump equipment but also lowers production efficiency and causes unnecessary energy waste.

The Continuous Crystallization Evaporator exclusively developed by Kaida Evaporation Crystallization Co. perfectly solves this technical challenge. With its unique crystallization tank design, it meets the process requirements of continuous feeding and discharging. The evaporator's forced circulation ensures a good match, and its internal structure effectively and rapidly separates crystals from the clear liquid. Additionally, the use of forced circulation evaporation and discharge technology perfectly synchronizes evaporation with crystallization, significantly enhancing production efficiency and reducing energy consumption.

Key Features:
1SeveralEvaporatorOperation involves connecting the units, where the secondary steam generated during evaporation in the first evaporator is used as the heating steam for the subsequent evaporator, offering all the advantages of multiple-effect evaporation.

2Repeatedly utilized heat energy, significantly reducing heat energy consumption.

3During the evaporation process, material heating is achieved through forced circulation, ensuring fast flow inside the tubes, even heat distribution, high heat transfer coefficient, and preventing wall dry-out.

4.Based on the material properties and the degree of evaporation, single-effect or multi-effect evaporator units can be designed. This unit is mainly suitable for solutions with crystalline precipitation.

5.Crystallization and discharge are synchronized, significantly reducing material blockage and structural risks, and extending the lifespan of the equipment.

6.Simultaneous material release, saves production time, significantly enhances efficiency.
