Multiple-effect evaporation, vacuum evaporation; the secondary steam is reused after being mechanically compressed or subjected to jet thermal compression; steam condensate is flash-evaporated or used for heating the feed; high-efficiency evaporators are employed, etc.
The evaporation device is not specified, so the response may vary. Generally, pay attention to the following points: 1. During vacuum evaporation, the vacuum level is very important; it is necessary to check the airtightness of the system ； It is also important for the vacuum pumping device to achieve its rated pumping capacity. 2. Good heat transfer in the heater or cooler is also a key factor for energy savings ； To achieve good heat transfer, it is also important to drain the water and non-condensable gases from the system at regular intervals when using steam for heating ； 3. The material being evaporated should not leak; all liquid levels should be normal with no leakage of material. If a foam catcher is present, it must be in good condition and free from any damage.
