CIP清洗系统（Clean In Place，原位清洗系统）是一种广泛应用于食品、饮料、制药等行业的自动化清洗技术，通过封闭管道循环清洗液实现设备内部的无拆卸清洗。
一、系统组成与工作原理
1.核心组件
· 清洗液罐：酸罐、碱罐、热水罐（材质通常为SUS304/316L不锈钢），用于存储不同清洗介质。
· 循环泵组：驱动清洗液在管道内形成湍流，增强冲刷效果。
· 控制系统：PLC或触摸屏控制，可预设清洗程序（如碱洗→酸洗→消毒）并实时监测温度、电导率等参数。
2.清洗流程
· 预冲洗：常温清水去除松散污物。
· 主清洗：碱液（60-80℃）去除脂肪/蛋白质，酸液（如硝酸）溶解矿物质结垢。
· 终洗与消毒：热水（85℃以上）或灭菌剂杀灭微生物。
二、技术优势
1.高效与安全
· 全自动操作减少人工干预，清洗时间缩短50%以上（如乳品罐清洗仅需20-30分钟）。
· 密闭循环设计避免二次污染，符合GMP/FDA卫生标准。
2.节能环保
· 回收清洗液重复利用，水耗降低30%-50%。
· 模块化设计支持分区清洗，可边生产边清洗。
3.适应性广
· 适用于管道、罐体、泵阀等复杂设备，清洗覆盖率可达99%。
三、典型应用场景
· 乳品行业：牛奶冷藏罐的360°无死角清洗，微生物检出率为0。
· 制药行业：无菌生产线设备清洗，满足验证要求。
· 饮料/啤酒厂：管道与发酵罐的定期维护，防止批次交叉污染。
CIP cleaning system (Clean In Place) is an automated cleaning technology widely used in industries such as food, beverage, and pharmaceuticals. It achieves non disassembly cleaning of equipment interior by circulating cleaning solution through closed pipelines.
一、 System composition and working principle
1. Core components
Cleaning solution tank: acid tank, alkali tank, hot water tank (usually made of SUS304/316L stainless steel), used to store different cleaning media.
Circulating pump set: Drive the cleaning solution to create turbulence in the pipeline, enhancing the flushing effect.
Control system: PLC or touch screen control, can preset cleaning program (such as alkali washing → acid washing → disinfection) and monitor temperature, conductivity and other parameters in real time.
2. Cleaning process
Pre rinsing: Remove loose dirt with clean water at room temperature.
Main cleaning: Alkali solution (60-80 ℃) removes fat/protein, acid solution (such as nitric acid) dissolves mineral deposits and scales.
Final washing and disinfection: Use hot water (above 85 ℃) or sterilizers to kill microorganisms.
二、 Technical advantages
1. Efficiency and safety
Fully automated operation reduces manual intervention and shortens cleaning time by more than 50% (e.g. dairy tank cleaning only takes 20-30 minutes).
The closed-loop design avoids secondary pollution and complies with GMP/FDA hygiene standards.
2. Energy conservation and environmental protection
Recycling and reusing cleaning solution reduces water consumption by 30% -50%.
Modular design supports zone cleaning, allowing for simultaneous production and cleaning.
3. Wide adaptability
Suitable for complex equipment such as pipelines, tanks, pumps and valves, with a cleaning coverage rate of up to 99%.
三、 Typical application scenarios
Dairy industry: 360 ° no dead angle cleaning of milk refrigerated tanks with zero microbial detection rate.
Pharmaceutical industry: Clean sterile production line equipment to meet validation requirements.
Beverage/Beer Factory: Regular maintenance of pipelines and fermentation tanks to prevent batch cross contamination.
