Product Description

vaccum ethanol separation falling film evaporator stainless steel


Product Description


The falling film evaporator is widely used in the evaporation and concentration of water or organic solvent solutions in the pharmaceutical, food, chemical, light industry and other industries, and can be widely used in the waste treatment of the above industries. The falling film evaporator is especially suitable for heat sensitive materials. The whole equipment is continuously operated under vacuum and low temperature conditions, with high evaporation capacity, energy saving, low operating cost, and can ensure the material is invariable during evaporation.



The falling film evaporator is very popular in industrial, chemical, biochemical, food and other fields, because it has high efficiency, practical and economic benefits. The practical and economic benefits can be concluded as follows:

(1) The falling film evaporator is a concentrating device belonging to the natural circulation, and the heat transfer efficiency is very high during use, which saves a lot energy.

(2) Since the evaporation temperature of the falling film evaporator is relatively low, during operation, a part of the secondary steam passes through its hot press pump and is re-inhaled into the next heater, which forms a recyclable utilization.

(3) The falling film evaporator can use the disc or tube bundle dryer exhaust gas and other low calorific value heat sources as the heat source of the evaporator to a certain extent, so that the amount of steam can be greatly reduced,which can achieve the effect of energy saving. When the waste steam has a sufficient supply, it is possible to use no raw steam, so that significant economic benefits can be achieved.


The working principle of falling film evaporators can be described as follows. 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.

1. Why is single-effect falling film evaporator commonly used for ethanol recovery?
Ethanol has low heat content and is volatile, so it is not suitable for multi-effect falling film evaporator.

2. What is the feed temperature of the single-effect falling film when recovering ethanol?
It is recommended to be above 20 °C, if the low temperature material liquid can add a preheating device before the cloth.

3. How much is the steam pressure in the heating chamber controlled?
The steam pressure is controlled within 0.2MPa, and the temperature is within 130 °C.

4. How to control the steam temperature?
By adjusting the steam pressure to adjust the steam temperature, the temperature changes with the pressure.

5. What material is the single effect falling film evaporator, can it be made of 316 material?
Hygienic grade 304 material. According to customer needs can be made of 316 material.

6. Is the single-effect falling film evaporator controlled automatically or manually?
Manual control. According to customer needs can make automatic control system.

7. Can 200L single effect falling film evaporator be sent by air?
After special packaging design, it can be sent by air.
