Concentrating System

The advantage of the wet fish meal production process is that it can handle raw materials with high  fat content. Pressing the raw materials will get 2/3 of the press liquid. After recovering the fish  solid and fish oil, there is still a large amount of nutrient-rich stickwater. It is made into a  concentrate and then send to the dryer to make fishmeal, which accounts for about 20% of the  fishmeal yield. This important work is accomplished by the concentrating system, this system can  shorten drying time and can increase fishmeal quality;

NJ concentrating system consists of I and II effect evaporators, I and II effect separators, vacuum  condenser and five pumps. Through vacuum sealing, we use waste steam from dryer as heat source,  evaporate water at 42℃, continuously recycle fish protein water to produce concentrate;

The  distilled water produced by the concentrated system has no pollution to the environment and is an  efficient and energy-saving equipment.
