fishmeal evaporator [Oct 12,2016]
Evaporators for stickwater are very important, because they recover dry matter that will increase the yield of meal by 20% or more, depending upon the freshness and nature of the raw material. Furthermore, they eliminate a serious pollution problem that today appears unacceptable, particularly in the vicinity of densely populated areas.
There are there kinds of evaporators:
(1). Double effect falling film evaporator
(2). Double effect climbing film evaporator
(3). Triple effect falling and climbing evaporator
The double effect falling film evaporator is now used more widely than the other two, so here we just discuss the first one only.
