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.
Features
1. Low heating temperature
2. High evaporation speed
3. Short liquid residence time
4. Continuously feeding and discharging
5. Suitable for heat sensitive materials
6. Energy-saving
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.
