Triple Effect Falling Film Evaporator

The Triple 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.

• Low heating temperature
• High evaporation speed
• Short liquid residence time
• Continuously feeding and discharging
• Suitable for heat sensitive materials
• Energy-saving

Triple Effect Falling Film Evaporator is widely used in food, dairy, chemical, 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.

We design and manufacture extraction prodcution line for users in need of a simple device for small amounts of extract, as well as more complex equipment for industrial use. Our offer includes preprocess(dryer /grinder) ,coating machine ,package machine and process systems where the substance used as solvent is either a volatile hydrocarbon (butane extraction), an alcohol (alcohol extraction), or CO2 (supercritical extraction). Given the investment cost, complexity of use, and extract quality, each system has some advantages and disadvantages.
