Four-effect Falling Film Evaporator

1. The system features uniform steam heating and liquid film flow evaporation, offering high heat transfer efficiency and short heating time. With the addition of a thermal compression pump, it further provides advantages such as energy and consumption reduction, low steam consumption, and low cooling water circulation.
2. The material accelerates and flows downward under pressure along the inner wall of the tube for evaporation, making it suitable for evaporating and concentrating highly viscous liquids.
3. Since the material evaporates in a thin film inside each tube, the heating time is very short, which is highly beneficial for food evaporation and concentration, preserving the nutritional components of the food.
4. The evaporation process occurs under vacuum, ensuring both hygiene and environmental requirements while significantly lowering the evaporation temperature. Combined with the thermal compression pump, part of the secondary steam is re-inhaled and mixed with live steam, saving live steam. Additionally, as the steam from the thermal compression pump enters the heating shell in a jet mist form, it rapidly diffuses, providing gentle heating to the material, making it suitable for concentrating heat-sensitive substances.
5. The equipment is suitable for evaporating and concentrating foamy materials. As the material evaporates in a thin film inside the heating tubes, vapor-liquid separation occurs. Meanwhile, at the bottom of the effect body, most of the material is drawn away, with only a small portion entering the separator along with all the secondary steam for enhanced separation. The entire process avoids significant impact, preventing foam formation.
6. For food evaporation and concentration, the equipment can also serve a sterilization function. The material is preheated first, then enters the sterilizer, reaching above 94°C and maintaining this temperature for about 24 seconds before entering the first effect body, where it rapidly flash evaporates, causing an instant temperature drop.
7. The equipment can be equipped with a CIP cleaning system for in-place cleaning, ensuring easy operation and no dead ends.
8. The equipment allows for continuous feeding and discharging.
9. The equipment can be configured with an automation system to achieve automatic control of feeding volume, heating temperature, discharge concentration, and cleaning. It can also include protective measures for sensitive materials during sudden power outages or malfunctions, along with automated alarm and control operations.
