1、 Scope of application
Double-effect falling film evaporator is suitable for low-temperature continuous evaporation and concentration in milk, glucose, starch, xylose, pharmaceutical, chemical, biological engineering, environmental protection engineering, waste liquid recovery and other industries. It has the main characteristics of high heat transfer efficiency and short heating time of materials, so it is especially suitable for materials such as heat sensitivity, viscosity and foaming.

2、 Equipment composition
Heating evaporator, separator, condenser, hot-press pump, sterilizer, insulation pipe, vacuum system, feed liquid delivery pump, condensate drainage pump, operation platform, electrical instrument control cabinet, valve, pipeline and other systems.

3、 Main features
1. The whole heating system of the equipment has high heat transfer efficiency and short heating time due to uniform steam heating and liquid film flow evaporation
Etc. If the hot-press pump is configured again, it has the advantages of energy saving and consumption reduction, low steam consumption and low cooling water circulation

2. The material is accelerated to flow and evaporate under pressure downward along the inner wall of the pipe to adapt to the evaporation and concentration of the material liquid with high viscosity.
3. Because the material is evaporated in a film form in each tube, the heating time of the material liquid is very short, so it is particularly beneficial to the evaporation and concentration of food, and the nutrition of food is largely preserved.
4. The evaporation process under vacuum not only ensures the sanitary requirements of the material, but also ensures the environmental protection requirements, and greatly reduces the evaporation temperature. In addition, with a hot-press pump, part of the secondary steam is re-injected and mixed with the raw steam through the hot-press pump, which not only saves the raw steam, but also because the steam through the hot-press pump enters the heating shell in a spray form, the steam diffuses rapidly, and the material liquid is heated gently, Therefore, it is suitable for the concentration of heat-sensitive materials.
5. The equipment is suitable for evaporation and concentration of foaming materials. Since the feed liquid evaporates in a film form in the heating tube, vapor liquid separation is formed. At the same time, at the bottom of the effect body, most of the feed liquid is pumped away. Only a small part of the feed liquid and all the secondary steam enter the separator to strengthen separation. The feed liquid does not form too much impact during the whole process, avoiding the formation of foam.
6. For food evaporation and concentration, the equipment can also have sterilization function. The material is preheated first, and then enters the sterilizer, reaching above 94 degrees, for about 24 seconds, and then enters the single-effect body. The material flash quickly, and the temperature drops instantly.
7. The equipment can be equipped with CIP cleaning system to realize on-site cleaning. The whole set of equipment is easy to operate without dead angle.
8. Continuous feeding and discharging of equipment.
9. The equipment can be equipped with automatic system to realize automatic control of feed quantity, heating temperature, discharge concentration, cleaning, and protection measures for sensitive materials in case of sudden power failure and failure. Other automatic operation and control of safety and alarm.
