Clean in place processes sit at the intersection of production efficiency and food safety compliance, and when a customer’s quality assurance team identified the need for a hot water rinse step in their can seamer cleaning process, the requirement was as much about creating a verifiable, repeatable cleaning standard as it was about the mechanical implementation of the rinse itself.
The challenge
As part of the customer’s QA requirements, Bevtech was engaged to implement a hot water rinse as part of the CIP cleaning process for their can seamer. The brief went beyond simply adding a hot water rinse cycle, the customer needed the resulting process to be controllable, repeatable, and verifiable, with the ability to start and stop the cycle from a central interface and confirm, with actual instrumentation rather than operator assumption, that each cycle had genuinely met its required temperature and flow parameters.
The solution delivered
Bevtech’s electrical and automation team designed and installed a Siemens 1200 series PLC with a Siemens HMI to control the upgraded CIP process, supported by temperature sensors and flow sensors providing real time feedback on cleaning cycle performance, along with associated control gear to manage valve actuation and process sequencing. The resulting system allowed the cleaning process to be started and stopped directly from the HMI, with configurable parameters letting the customer adjust cycle settings as required, and diagnostic elements built into the interface giving operators immediate visibility into cycle status and any deviation from the required parameters.
This instrumentation based approach was central to meeting the customer’s underlying compliance objective. Rather than relying on a fixed cycle duration and assuming the cleaning standard had been met, the temperature and flow sensors provided actual verification that the hot water rinse achieved its required parameters on every cycle, creating a far more robust compliance position than a time based assumption alone could offer.
Why precise instrumentation mattered
For a can seamer CIP process, the hot water rinse step plays a direct role in meeting hygiene standards before the equipment returns to production contact with product. A cleaning cycle that runs for the correct duration but at insufficient temperature, due to an undetected heating fault, would not actually achieve its intended hygiene outcome despite appearing complete from a simple timer based perspective. By instrumenting the process with temperature and flow sensors feeding back into the Siemens PLC, the system can detect and flag exactly this kind of fault, low temperature, inadequate flow, or a failed valve actuation, rather than allowing an ineffective cycle to complete unnoticed and the line to return to production believing the cleaning standard had been met when it had not.
The outcome for the customer
The completed system gave the customer a controllable, repeatable hot water rinse process integrated into their existing CIP cycle for the can seamer, with the diagnostic visibility to immediately identify any cycle that did not meet its required parameters, rather than discovering a gap in cleaning standard only through downstream quality issues or an audit finding. This shifted the process from a manually managed, assumption based cleaning step to a properly instrumented, verifiable control system aligned with the customer’s quality assurance requirements.
A model for CIP upgrades more broadly
This project reflects a pattern that applies to CIP and cleaning process upgrades generally across food and beverage manufacturing, that the real value of a control system upgrade in this context is not simply automating what was previously a manual step, but adding the instrumentation and feedback needed to verify, rather than assume, that the cleaning standard has actually been achieved. For manufacturers relying on manually timed or loosely monitored CIP processes, this kind of upgrade offers a meaningful improvement in both compliance assurance and operational reliability.
