There are many defrosting methods, such as manual defrosting, refrigerant hot defrosting, water defrosting, electric heating defrosting and so on.

The surface temperature of the evaporator during the normal operation of the cold storage refrigeration system is much lower than the dew point temperature of the air, and the mois

Frequently check the frosting condition of the evaporator. When the frost layer is too thick, it should be defrosted in time.

​Frequent leak detection of evaporator. Leakage is a common failure phenomenon of evaporators, and you should pay attention to frequent leak detection during use.

The calculation method of the evaporation area of the ice storage evaporator is the same as that of other cold room evaporators.

However, if the evaporated material liquid is not allowed to be contaminated by the flue gas, this type of evaporator is generally not applicable.

In actual production, evaporators that directly contact heat transfer are sometimes used. It mixes fuel (usually gas and oil) with air and burns in a combustion chamber immersed in

Due to gravity, centrifugal force and the action of the rotating scraper, the solution forms a down-rotating film on the inner wall of the vessel, which is evaporated and concentra

The evaporator shell of the scraper evaporator is equipped with a heating steam jacket, which is equipped with rotatable blades or scrapers.

The residence time of the solution in the evaporator is very short, so it is especially suitable for the evaporation of heat-sensitive materials;

However, because the liquid film is not easily distributed uniformly in the tube, and the heat transfer coefficient is smaller than that of the rising film evaporator, it is still

The difference between a falling film evaporator and a rising film evaporator is that the feed liquid is added from the top of the evaporator.
