Falling Film Evaporator SS304 FFE-20 2.4KW

Falling Film Evaporator Description

The falling film evaporator can be continuously operated under vacuum and low temperature conditions, with high evaporation capacity, energy saving, consumption reduction and low operating cost. It can maintain the original color, aroma, taste and ingredients of the processed materials to the maximum extent. As an essential evaporation equipment, It is widely used in many industries such as food, medicine, food deep processing, beverage, light industry, environmental protection, chemical industry and other fields. The evaporator can be designed into different process flow according to the characteristics of different materials to be processed, and can also be equipped with automatic control system according to the requirements of different users.

A falling film evaporator consists of the evaporator (heat exchanger), separator, preheater, condenser, condensate tank, circulation pump and other components. It works from the top to the bottom downwards. In the operation of falling film evaporators, the materials are added from the upper part of the heating tube. They are evenly distributed into each falling film pipe through the distributor, and flow down the wall of the pipe in the state of a liquid film. Under the action of gravity and the secondary steam flow, the materials get evaporated while flowing down. At the bottom of the falling film tube, the materials and secondary steam are basically separated, and they reach the separation chamber to achieve complete separation.

Maintenance

1. Always check whether the oil cup of the pump is short of oil, and whether the cooling water in the mechanical seal is broken.
2. Always check the flanges and joints of the equipment for air leakage.
3. When the mechanical seal of the pump is damaged, it should be replaced in time.
4. When the check valve rubber ball and rubber gasket are damaged, they should be replaced in time.
5. If the indications such as thermometer, vacuum gauge, pressure gauge, etc. are inaccurate, they should be proofread or replaced in time.
6. The surface of the equipment should not be rubbed with a hard scrubbing tool (such as steel brush) to avoid scratches and scratches on the stainless steel surface.
