Decentralised CIP --- A building block to assure product quality
Conventional CIP (cleaning in place) systems normally have central responsibility for the cleaning of several production areas. These central CIP systems often have several cleaning circuits so that several areas can be cleaned at the same time. The systems have at least four large re-use tanks so that each cleaning agent can be used on multiple occasions. These CIP systems have found an amazing level of acceptance although this concept is not really compatible with high standards. The standard at certain points is often uncompromisingly high as it is in other areas of the industry although the real effect may sometimes hardly be verifiable. On the other hand, traditional approaches may often be maintained at the same time and the associated detrimental effects “conditionally” accepted. A CIP cleaning system in an operation with high quality standards for its own products must not in any way accept the spread of impurities into other production areas via the CIP system. This possibility of spreading impurities must be completely ruled out. Amazingly there is still a market for central CIP systems. This means that we too must continue to offer these systems. The correct solution would, however, involve the purchase of our “Decentralised CIP”. By making this purchase, the operator of a production facility lays a significant building block for seamless maintenance of product quality right from the start. The “Decentralised CIP” is installed within the respective production areas and it has exclusive responsibility for the cleaning of this area. As a result of this, several decentralised CIP systems are used in a large manufacturing plant. These decentralised CIP systems can be connected to a central supply of chemicals via a ring line (supply of alkaline solution) or stub pipes (for acidic cleaning concentrates among others). In addition to complete security against the spread of impurities, there are other notable benefits. The systems are considerably more compact as only the main cleaning agent is used on multiple occasions (re-used). There is usually only one re-use tank connected to a decentralised CIP system. The cleaning concentration and the number of multiple uses (re-use) of a cleaning solution can be adapted precisely to the respective cleaning task. The consumption of chemicals is therefore lower for each cleaning cycle. The CIP cleaning can also be started at any time. This is in contrast to a central CIP system where several production areas may be waiting to be cleaned and may be queueing up under certain circumstances. A central CIP system does not have any single advantage over a decentralised system. There are no advantages in either the level of automation or the consumption of water and chemicals. It is, however, not particularly easy to understand the principle if standard central CIP systems have been used up to this point. Switching to a decentralised cleaning system is a measure which will increase quality.
