We absorb both the domestic and the overseas advanced technology successfully to research the double concentrating system in NJ series with following characteristics:
1. It is in a vacuum hermetic condition when running. The water will be evaporated at more than 42ºC. It is an energy saving system for using the wastage from drier as heat resource. It is fit for all the drying and concentrating work.
2. It is also used for flowing work. If it compounds with the reflecting boiler, the fish paste products will be produced.
3. It deals with stick water during the process of fishmeal production and it will discharge distilled water and produce concentrated liquid without environmental pollution.
