Falling film evaporation concentrator

Falling film evaporation concentrator

1、 Scope of application
The falling film evaporator is an efficient one-way non circulating membrane evaporation equipment, which has the characteristics of high heat transfer efficiency, large heat transfer coefficient, small temperature difference loss, short material heating time, not easy to deteriorate, easy multi effect operation, low energy consumption, and small equipment volume.Suitable for concentrating materials such as milk, juice, biochemistry, pharmaceuticals, seasonings, food additives, etc.

2、 Equipment composition
Heaters, separators, condensers, preheaters, vacuum systems, heat pumps, electrical instruments, control cabinets, work platforms, etc. materialSUS304orSUS316LAccording to the material and process requirements.

3、 Equipment features
1. The material stays in the heating tube for a short time,Especially suitable for evaporation and concentration of heat sensitive materials and materials with low concentrations that are not easily crystallized. Can feed continuously and discharge continuously;
2. The evaporation temperature is relatively low, and the efficiency and evaporation temperature can be selected according to customer requirements;
3. The falling film evaporator is a process in which the feed liquid is added from the upper tube box of the evaporator and evenly distributed into various heat exchange tubes through the liquid distribution and film formation device. Under the combined action of gravity, vacuum induction, and airflow, the liquid flows in a uniform film shape from top to bottom. During the flow process, it is heated by the shell side heating medium, and the liquid vaporizes. The generated steam and liquid enter the separation chamber of the evaporator together, and the steam and liquid are fully separated. The secondary steam enters the next effect evaporator as the heating medium, thus achieving multi effect falling film operation.
4. The condenser has a unique structure, high heat transfer coefficient, and good performance;
5. Adopting a jet hot press pump, the energy-saving effect is significant;
6. We can use both automatic and manual control models according to customer requirements.

7.Driving and parking are easy and fast to operate. It can be conveniently observed through a sight glass or liquid level for evaporation, and can be easily adjusted.

8The residual material in the evaporator is very small, and the driving time is short. After parking, the material in the evaporator can be quickly emptied.

9.The multi effect falling film evaporator has strong adaptability to flow changes and can operate efficiently over a wide range of flow rates.

10.The material can be heated and evaporated only once through the heat exchange tube, and the heating time of the material is short. The falling film evaporator can ensure the excellent quality of heat sensitive materials.

11.The temperature difference loss of falling film evaporation is small, without the boiling point increase caused by liquid static pressure, and can still ensure a high heat transfer coefficient under small temperature differences. It can operate normally and efficiently even under very small temperature differences, making it easy to achieve multi effect operation and achieve the goal of reducing steam consumption.
