An overview of CIP systems used in the brewery

The main terminologies used to describe the operation of the CIP system relate to the direction of the CIP cleaning flnid. The CIP fluid leaving the CIP storage tank is 

The operating cost of the CIP system is influenced by the amount and concentration of detergent used and whether it is recovered or not. Table 10.1 shows an example of typical CIP timings for the main process vessels and pipework. 

In summary, single use CIP systems are less capital intensive, require less space and reduce the risk of cross-contamination as compared to recovery CIP systems. The single use CIP system is important for specific applications such as yeast handling. In comparison, recovery CIP systems have lower energy requirements, volumes of water 

CIP systems can pump prerinse material, detergents and final rinse water to remove soil. The prerinse material (potentially dilute caustic) is used to remove any loose debris, whereas the detergents chemically remove the soil. Described below are the different detergents that can be used in CIP systems and also chemical additives such as sequestrates (chelating agents) and surfactants that improve detergent penetration. 

Detergents are used to chemically remove soil. Ideally the detergents are nonfoaming or include antifoam, free rinsing/nontainting, noncorrosive and have minimal environmental impact. Appropriately formulated detergents are effective at removing
