We provide three evaporator systems, which are multi-effect tubular evaporator system,MVR evaporator system and plate type evaporator system. The evaporator is mainly composed of heating chamber and evaporation chamber. The heating chamber provides the heat needed for the liquid to evaporate and promote the liquid to boil and vaporize; The evaporation chamber separates the gas-liquid phase completely. Multi-effect tubular evaporators are commonly used in the production of maltose, glucose, maltodextrin and fructose. Plate type evaporator can be used in sugar industry, chemical industry, food industry and pharmaceutical industry. MVR evaporator is usually used in the production of maltose and glucose, and can also be used in medicine, food and other fields.
