降膜式蒸发器的分程及其注意事项

摘要

降膜式蒸发器的特点是料液在蒸发器中受热的时间较短，减少受热时间可以最大限度保持料液中有益元素不被破坏，从而保证产品的品质。分程是因为降膜管的周边润湿量不足，为防止结垢结焦加速或干壁现象产生，需采取分程的方法进料用以加大降膜管的周边润湿量。本文仅以YNNM03-3800型三效降膜式蒸发器在椰奶生产中的应用为例进行阐述。%The characteristics of falling iflm evaporator is that material liquid in the evaporator heat time is shorter, can reduce the heating time is maximum keep the material liquid in the beneifcial elements is not destroyed, thus ensuring the quality of the products. Points cheng enough because the surrounding the tube wetting, so as to prevent scaling coking acceleration or dry wall, take points process method of feeding amount to increase the surrounding the tube wetting. Only YNNM03-3800 type three-way falling iflm evaporator in the application of coconut milk production as an example was introduced.
