Scope of application: multi-effect falling film evaporator multi-effect falling film evaporator is suitable for milk, glucose, starch, xylose, pharmaceutical, chemical and biological engineering, environmental engineering, waste liquid recycling industry such as low temperature evaporation and concentration, continuous has high heat transfer efficiency, shorter time for heating the material such as the main characteristics, so especially suitable for heat-sensitive, viscosity and foam materials.
Multi-effect falling film evaporator system composition: the heating effect, condenser, evaporator, the effect separator hot-pressing, sterilizer, insulation pipe, vacuum pump system, the effect of material liquid pump, condensate drainage pump and operation platform, electrical instrument control cabinet, valves and piping system.
Falling film key features:
1. The device added whole heating system due to steam heating uniformity, I feed liquid to liquid film flow evaporation, so has high heat transfer efficiency and other main characteristics of short heating time. Such as relocation compression pump, more energy saving, low steam consumption and low cooling water circulation.
2. The material flow speed down the tube wall pressure evaporation, adapt to the larger material liquid viscosity evaporation concentration.
3. Because the material in each root canal into membrane evaporation and material liquid heating time is very short, so evaporation and concentration is very good, especially for food larger preserve the nutrition of the food.
4. Under the effect of vacuum evaporation process, both to ensure that the material of the health requirements, at the same time to ensure the requirements of environmental protection, at the same time, greatly reduces the evaporation temperature, plus configuration compression pump, part of the secondary steam by hot-pressing pump suction mixed with raw steam again, save raw steam, both at the same time by hot-pressing pump heating steam spray fog shaped into the shell, steam quickly spread, mild material liquid heating, so the suitable concentration of thermal sensitive material.
5. The equipment is suitable for evaporation and concentration, foam materials due to the material liquid into membrane evaporation in the heating tube, which form the gas-liquid separation, in effect at the bottom of the body at the same time, most of the material liquid is siphoned off, only a little part of material liquid and all secondary steam enters the separator separation, the whole process of material liquid forming no too big impact, to avoid the formation of bubbles.
6. For food, evaporating equipment can have sterilization function at the same time, the material after preheating first, and then into the sterilizer, reach more than 94 degrees, 24 seconds, which entered a work efficiency, rapid flash of material, temperature in an instant.
7. The equipment can be equipped with CIP cleaning system, the realization of in-place cleaning, a complete set of equipment is easy to operate, no dead Angle.
Equipment in and out of the material. 8.
9. The equipment can be configured automation system, realize the feed rate of the automatic control, the heating temperature automatic control, automatic discharging concentration control, automatic control, cleaning can also be equipped with a sudden power failure, failure protection for sensitive material. Other safety, alarm and other automation and control.
