    Case Study: Hot Water Rinse CIP Upgrade for Can Seamer Compliance

    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.

  • CIP System Upgrades: Protecting Product Quality and Compliance

    CIP System Upgrades: Protecting Product Quality and Compliance

    Clean in place, or CIP, systems do not produce a single unit of saleable product, yet they sit directly on the critical path for both product quality and regulatory compliance on most beverage production lines. A CIP process that is unreliable, poorly instrumented, or running on outdated control logic creates risk on two fronts simultaneously, it can compromise the hygiene standard the cleaning cycle is meant to deliver, and it can delay the next production run if the cycle does not complete correctly and needs to be repeated before the line can restart.

    Why CIP reliability deserves more attention

    Because CIP cycles typically run during off peak hours, overnight or between production runs, control system faults in the CIP process are often discovered at the worst possible time, when the morning shift arrives expecting a clean line ready for production and instead finds an incomplete or failed cleaning cycle that needs to be rerun before anything else can happen. This not only delays the start of production but compresses the available production window for that day, with knock on effects across despatch schedules and customer commitments. Beyond the operational disruption, an unreliable CIP process creates genuine food safety and quality assurance risk, since the entire purpose of the cycle is to meet a defined hygiene standard before product contact equipment returns to service.

    A practical example: hot water rinse upgrade for a can seamer

    A useful illustration of what good CIP control delivers comes from a recent project where a customer’s quality assurance requirements called for the implementation of a hot water rinse as part of the CIP cleaning process for their can seamer. The upgrade involved installing a Siemens 1200 series PLC, a Siemens HMI, temperature sensors, flow sensors, and associated control gear, allowing the cleaning process to be started and stopped directly from the HMI with configurable parameters and diagnostic feedback built in. This kind of upgrade transforms a CIP process from a manual, loosely monitored sequence into a controlled, repeatable cycle with proper temperature and flow verification, parameters that matter directly to whether the cleaning standard actually meets the required QA specification rather than simply being assumed to have worked.

    What modern CIP control delivers

    A well instrumented CIP system, with temperature sensors, flow sensors, and conductivity monitoring where chemical concentration matters, provides verifiable evidence that each cleaning cycle met its required parameters, rather than relying on operator assumption that a cycle of a certain duration was sufficient. This matters enormously for audit and compliance purposes, since a documented, data logged CIP cycle gives a clear record to demonstrate to auditors or customers that hygiene standards were consistently met, rather than depending on manual logbooks that are easy to fill in retrospectively and difficult to verify.

    From an operational reliability perspective, HMI based diagnostics also mean that when a CIP cycle does fail or run outside parameters, the cause is immediately visible, a low flow alarm, a temperature that did not reach setpoint, a valve that failed to actuate, rather than requiring a technician to manually trace through the entire cleaning sequence to identify what went wrong. This dramatically shortens the time needed to diagnose and rerun a failed cycle, reducing the knock on delay to the next production run.

    The compliance and downtime business case

    For procurement and operations teams evaluating a CIP control upgrade, the business case combines two distinct value streams, reduced compliance and quality risk from verifiable, data logged cleaning cycles that withstand audit scrutiny, and reduced production delay from faster fault diagnosis and fewer failed cycles requiring a full rerun. Both of these are difficult to quantify with the same precision as a direct throughput improvement, but for manufacturers supplying major retail or beverage brand customers who routinely audit supplier hygiene and quality systems, the compliance assurance value alone often justifies the investment.
