Overview
falling-film evaporator
Product Details
falling-film evaporator
Application of triple effect falling film evaporator:
Our factory has developed a three effect evaporator for corn steep liquor (CORN Streep Liquor, commonly known as corn syrup) and starch syrup (Starch Syrups or Glucose Syrus), which are designed to obtain highly nutritious soluble protein and high concentration syrup, respectively, to provide process conditions for final drying.
In the evaporation devices of the two different media mentioned above, the feed is a pumped dilute liquid, while the product obtained from the evaporation heat separation process, namely the discharge, is still a pumpable liquid, although it is a high concentration corn soaking solution (48-50% DS) or a high concentration starch syrup (65-80% DS).

1. Type and layout
For corn soaking solution and starch syrup evaporator, the starting point of success is for the system to fully and accurately grasp the dynamic changes of material related parameters in the thermal separation process, thereby obtaining complete design basis information, mastering the critical conditions of each stage, and ultimately finding and determining the best design scheme, while meeting specific customer requirements and conditions.
Generally speaking, the relevant parameters mainly refer to the reasonable concentration segmentation, maximum allowable temperature, duration of material flow in the device, segmented values of material viscosity change and boiling point increase during the entire evaporation process of the product from feed to discharge.
Our factory provides a falling film evaporator that operates under vacuum conditions, providing fine, gentle, and safe processing conditions for product evaporation with low boiling point and short material flow time; Considering the strong risk of crust formation in corn soaking solution and its increasing concentration, it is concentrated in a two-stage falling film evaporator before being finally concentrated in a first stage forced circulation evaporator. Practice has proven that our unique process arrangement can effectively mitigate the risk of crust formation and extend the operation cycle of equipment cleaning (CIP).
2. Economic factors
The economy of an evaporator depends first and foremost on investment (initial cost) and operating costs, the latter of which also includes a significant energy cost factor. The combination of our three effect evaporation technology and secondary steam recompression technology (TRC) will reduce steam consumption to the most advanced level in China.
3. Satisfy customers
Our factory will fully consider the different conditions and requirements of each customer, among which the main issues are the customer's energy supply conditions, the natural conditions of the factory site and environment. Based on this, our factory will design individual evaporators for each customer, including type selection, process layout, temperature configuration, and control system selection.
4. Example
1. Corn soaking solution evaporator
A set of three effect continuous operation vacuum falling film forced circulation partial countercurrent evaporation device is used for the evaporation of corn soaking solution in 250T/d corn wet milling process, heated by a thermal compressor.
2. Corn syrup evaporator
Three effect continuous operation vacuum falling film parallel flow evaporator is used for glucose syrup, heated by a thermal compressor.
