Product Description

 

extractive distillation equipment vacuum single effect falling film brine evaporator

 

Product Description

 

The falling film evaporators are usually regarded as the high-efficiency evaporation equipment, especially suitable for heat sensitive material. Its evaporation system consists of evaporators, separators, condensers, hot press pumps, vacuum and drainage sysytems, various utility liquid transfer pumps, operating systems, electrical instrument control cabinets, valves, pipelines and other systems. The equipment can be used to separate the ethanol from material and condense and recover it through reduced pressure vacuum and evaporation. The single-effect falling film evaporator used for ethanol solution production is different from the general single-effect falling film evaporator used for aqueous solution production. Ethanol has a low boiling point and is volatile. Ethanol can be evaporated easily under vacuum and reduced pressure, so it has a small evaporation area. It is difficult to condense and recover ethanol vapor, so the heat exchange area of the condenser is relatively large. In order to obtain a good cooling effect, two or more stages are often used for cooling recovery, which is also different from the general aqueous solution evaporation.

Working Theory
The materials 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.

Applications
Single-effect falling film evaporator is widely used in food, dairy, chemical, pharmaceutical, biological engineering, environmental protection engineering and corn deep processing, such as for aqueous solutions, organic solvent solutions, fruit and vegetable juices, milk, eggs, vitamin C, collagen , Tea immersion liquid, sodium glutamate and other evaporative concentration. It is especially suitable for evaporative concentration of heat-sensitive materials, and the beneficial elements of the material can be protected to the greatest extent during the heating and evaporation process.

FAQ

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.
