Product Description
Scope of application: Double effect falling film evaporator, suitable for low-temperature continuous evaporation and concentration in industries such as milk, glucose, starch, xylose, pharmaceuticals, chemical, biological engineering, environmental engineering, waste liquid recovery, etc. It has the main characteristics of high heat transfer efficiency and short heating time of materials, so it is particularly suitable for materials such as heat sensitivity, viscosity, foaming, etc.
System composition: Each effect heating evaporator, each effect separator, condenser, hot press pump, sterilizer, insulation pipe, vacuum system, each effect liquid delivery pump, condensate drainage pump, operating platform, electrical instrument control cabinet, valves, pipelines, and other systems.
Main characteristics of falling film:
The entire heating system of the equipment has the main characteristics of high heat transfer efficiency and short heating time due to uniform steam heating and liquid film flow evaporation. If equipped with a hot press pump, it has the advantages of energy conservation and consumption reduction, low steam consumption, and low cooling water circulation.
2. The material accelerates the pressure flow and evaporation downwards along the inner wall of the pipe, adapting to the evaporation and concentration of high viscosity material liquid.
3. Due to the filmy evaporation of the material in each tube, the heating time of the material solution is very short, which is particularly beneficial for food evaporation and concentration, greatly preserving the nutritional components of the food.
4. Under the action of vacuum, the evaporation process not only ensures the hygiene requirements of the material, but also ensures environmental protection requirements, greatly reducing the evaporation temperature. In addition, equipped with a hot press pump, some of the secondary steam is re sucked in and mixed with the raw steam through the hot press pump, saving the raw steam. At the same time, due to the steam passing through the hot press pump entering the heating shell in a spray like manner, the steam quickly diffuses, and the material liquid is heated gently, So 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 to reach 94 degrees Celsius or above. After maintaining for about 24 seconds, it enters the first effect body, where the material quickly flashes and the temperature drops instantly.
7. The equipment can be equipped with a CIP cleaning system to achieve on-site cleaning. The entire equipment is easy to operate and has no dead corners.
8. Continuous feeding and discharging of equipment.
9. The equipment can be equipped with an automation system to achieve automatic control of feed volume, heating temperature, discharge concentration, cleaning, and protection measures for sensitive materials in case of sudden power outages or malfunctions. Other automated operations and controls such as security and alarm.
