FFE 200L Single-Effect Falling Film Evaporator
A single-effect falling film evaporator is a type of falling film evaporator, which is a concentration and evaporation device used in industries. It is applicable for the concentration and evaporation of water, organic solvents and solutions in the pharmaceutical, food, chemical, light industries and other industries, and it is especially suitable for heat sensitive materials and materials with higher concentration and higher viscosity. The equipment is continuously operated under vacuum and low temperature conditions, with high evaporation capacity, energy conservation, low operating cost. It can ensure that the material is invariable during the evaporation.
A 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.

The 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.
1. Why is a single-effect falling film evaporator commonly used for ethanol recovery?
A: Ethanol has low heat content and is volatile, so it is not suitable to use a multi-effect falling film evaporator.
2. What is the feed temperature of a single-effect falling film evaporator when recovering ethanol?
A: It is recommended to be above 20 ℃, 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?
A: The steam pressure is controlled within 0.2MPa, and the temperature is within 130 ℃.
4. How to control the steam temperature?
A: 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?
A: 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?
A: Manual control. According to customer needs can make automatic control system.
7. Can 200L single effect falling film evaporator be sent by air?
A: After special packaging design, it can be sent by air.
