China Forced Circulating Evaporator Evaporating Machine for Pharmaceutical

Forced circulation evaporator is suitable for scaling, crystal, thermal sensitivity(low temperature), high density, high viscosity raw material, and the evaporation water insoluble solids such as chemical, food, pharmaceutical, environmental protection engineering, waste water evaporation recycling industry.

Working principle
Forced circulation evaporator rely on external force--circulating pump. The circulation speed can be 1.5-3.5meters/seconds. The heat efficiency and production capacity is big, the raw material solvent from down parts to up parts by circulation pump. It flows along the pipe to the heating chamber, then the steam and liquid will be separated at the chamber, the steam will go out from up parts, the liquid will flow at the bottom of the chamber. It will be pumper by circulation pump again, it is again pumped to heating pipe, the heating chamber has horizontal and vertical structure, the liquid flow speed is controlled by pump. According to different circulation liquid inlet and outlet of separating chamber, it can divides to normal circulation evaporator and forced circulation evaporator. The inlet part of circulation liquid above the outlet part is called normal circulation, oppositely, it is forced circulation.

Main features
1. The structure of whole system design is reasonable and beautiful, stable operation, high efficiency and energy saving, low steam consumption.
2. Concentration ratio, forced circulation type, so that the viscosity liquid can be easily flow and evaporated. And it is evaporated during short time.
3. Special design through simple operation can be realized, can be used for production of different products.
4. Low evaporation temperature, heat is fully utilized, the liquid can be heated and concentrated warmly, it is suitable for heat sensitive materials.
5. The evaporator is heated by the forced circulation pump, so its heat evenly in the tube, the heat transfer coefficient is good which can prevent the "wall" phenomenon.
6. The liquid enters the separator to separate, to strengthen the separation effect, make the whole device has a wide operating range.
7. The complete set of equipment has the advantages of compact structure, small occupation area, simple and smooth layout, it shows the trend of big type of full evaporating device.
8. Continuous feeding and discharging, liquid level and the required concentration can be controlled by automatically.
