%98,5 赖氨酸生产工艺
Biochem
Turnkey
70% 纯 L-赖氨酸:
将葡萄糖、糖蜜、玉米浆和盐等原料按适当比例混合。混合物持续灭菌,然后输送至发酵罐。
发酵所需的空气经多级过滤器净化,并由无油螺杆空压机提供。
使用的发酵菌株为谷氨酸棒杆菌,培养过程持续 45 小时。
种子制备:先在烧瓶中培养,然后在种子罐中进一步培养,并进行曝气和添加水解产物。
发酵在专用发酵罐中进行,在受控的曝气、温度和 pH 条件下进行。持续添加无菌葡萄糖浆、硫酸铵和消泡剂。
发酵结束后,调节 pH 值,并通过微滤分离微生物细胞。生物质可用作动物饲料。
L-赖氨酸溶液先用活性炭脱色,然后过滤除去活性炭。
通过离子交换系统,使用各种树脂去除杂质(例如铁、镁、钙、氯、硫酸根等),进行纯化。
纯化后的溶液在真空蒸发器和结晶器中浓缩,以提高固含量。
结晶的L-赖氨酸被分离出来,湿产品被干燥以满足最终的水分要求。母液部分回收利用或与生物质混合用作动物饲料。

Description of Investment Components:
-
Machinery:
The machinery investment includes core equipment required for L-Lysine production from agricultural raw materials (e.g., wheat or corn). These include:
-
Wheat cleaning and steeping units
-
Wet milling systems
-
Fiber separation and germ recovery units
-
Gluten separation and starch refining systems
-
Fermentation tanks, seed culture systems
-
Evaporation, centrifugation, and drying systems
-
Storage silos, slurry handling systems
-
CIP (Cleaning-In-Place) systems
-
All related process lines and automation
Note: For 98.5% L-Lysine HCl, additional purification steps such as ion exchange, crystallization, and acidification with hydrochloric acid are included. These units are not present in the 68% purity (sulfate or liquid) L-Lysine setup, which requires simpler separation and drying processes.
-
Land & Construction:
The land and construction costs cover:
-
Industrial-zoned land
-
Production buildings
-
Administrative offices
-
Raw material & finished product warehouses
-
Laboratory units
-
Social facilities
-
Landscaping and site development
Note: Facility design for 98.5% purity plants may require additional cleanroom or controlled environment spaces due to higher product purity standards.
