Main advantages and structural composition of single effect falling film evaporator

The single effect falling film evaporator is mainly used for material thickening in liquid milk production. The material has a short heating time and a low evaporation temperature, maintaining the flavor of fresh milk. It is suitable for low-temperature vacuum concentration of materials with low concentration and heat sensitivity in industries such as food, chemical, pharmaceutical dairy, beverage, western medicine, starch, and industrial organic solvent (such as alcohol) recovery.

The main advantages of a single effect falling film evaporator include:

High heat transfer efficiency: The material liquid is evenly distributed on the inner wall of the heating tube using a falling film distributor, forming a thin film like flow. The heat transfer coefficient can reach 1390-2910 W/m ² · K, significantly improving the evaporation efficiency. ‌
