Lysine Project Introduction
Starch milk adjustment: The starch adjustment process adjusts the desired DS value. The starch milk from the workshop was sent to the starch adjustment tank. Also, dry starch can be used to make starch milk. The dry starch was mixed with adding water to get starch milk. The starch milk adjustment must adjust the DS value (DS=28%-32%). After reaching the desired DS value and starch milk adjustment, the milk is sent to the next section.
Liquefaction: Liquefaction is used to get the starch syrup. The adjusted starch milk is sent to the liquefaction system. The two-time ejection is needed to get a better liquefaction effect. After a better liquefaction effect, the material is sent to the flash tank for cooling; after cooling, the syrup is forwarded to the next stage for saccharification and further processing.
Saccharification: saccharification is used to reach desired DE value. The reaction happens with the aid of an enzyme. The system maintained the time and enzyme adjustment to respond well. After that, the syrup reaches the desired DE value. Then the glucose is sent to the flask tank for cooling and forwarded to the next stage for further processing.
Filtration and evaporation: Filtration is used to remove protein and other impurities. Filtration removes the protein and impurities from the glucose. The evaporator is used to concentrate the glucose to desired DS value. The glucose reaches to desired DS level from DS=30% to DS=70% after evaporation. Then the glucose is sent to the next stage for further processing.
Fermentation: Fermentation is used to change the internal structure of glucose into an L-lysine product. The process required adding corn stepping liquid, molasses, nutrient salt, and other auxiliary materials to the glucose; after the necessary materials were added to the glucose, the glucose was sent to the fermentation tank after continuous sterilization. L-lysine production maintains the controlled temperature and PH value. And continuously add the pure glucose syrup, ammonium sulfate solution, and antifoaming agent to assist fermentation. The fermentation process continues by maintaining the appropriate requirements for a specific time. Then the fermentation mash is obtained. Then the fermentation mash goes to the next stage.
Evaporation: Evaporation is used to concentrate the fermentation mash. Fermentation mash reach to desired concentration in the evaporation system. Then the material is sent to the drying section for drying.
Drying: Drying remove the excessive moisture from the material. The wet lysine contains the water released by the drier to get the desired granularity and humidity of the final product. Then the qualified lysine particles were sent to the packaging machine and forwarded to the warehouse. At last, the final packaged qualified lysine is obtained.
