Case Study

Context

A global infant nutrition manufacturer wanted to improve inspection consistency across multiple international spray dryer sites. Historically, each facility had been working with different contractors, reporting formats, and inspection frequencies, making it increasingly difficult to benchmark asset condition or manage hygienic risk in a reliable and uniform way.

The lack of standardisation meant that defect severity was being interpreted differently across locations, and there was no common framework to guide repair prioritisation or track asset health over time. The manufacturer needed a structured, long-term solution.

Challenges

We were brought in to design and deliver a unified nutrition manufacturing plant equipment inspection programme that could be applied consistently across all international sites. The scope covered spray dryers, cyclones, bag filters, fluid beds, and ducting systems. Beyond the inspection itself, the programme needed to include standardised defect classification, consistent reporting structures, repair prioritisation guidance, and the ability to track trends across facilities over time.

The Bioscan Response

Bioscan developed a standardised inspection programme and mobilised teams across the manufacturer’s global sites. Initial inspections carried out through industrial spray dryer testing identified significant variation between facilities, including undetected fatigue cracking, inconsistent repair quality, areas of recurring thermal stress, and differing interpretations of defect severity. What had appeared to be a managed asset base was, in reality, carrying a range of unresolved risks that had gone unquantified due to the absence of a unified approach.

Our spray dryer inspection methodology was applied uniformly across all sites, establishing a shared baseline for asset condition assessment. Industrial cyclone testing and bag filter crack testing were carried out as part of the same programme, ensuring full system coverage rather than isolated equipment checks.

We implemented unified inspection methodologies, risk-based repair classifications, global reporting templates, and a long-term defect monitoring framework to support ongoing asset management.

Outcome

The manufacturer gained greater visibility of asset condition across all sites, improved consistency in hygienic risk management, and a more reliable basis for shutdown planning. Confidence in the integrity of their production equipment increased measurably across the organisation.

Impact

This programme demonstrates the value of a coordinated, standards-driven approach to industrial equipment inspection across multi-site operations. When each facility operates in isolation, risk accumulates silently. Bioscan’s global programme replaced inconsistency with clarity, giving the manufacturer a repeatable, auditable framework for long-term asset integrity and industrial baghouse inspection management.

Context

A food ingredients manufacturer identified powder leakage from elevated process ducting located directly above a live production area. The leakage was not just an operational concern. It posed a serious risk of product contamination and raised combustible dust hazards that couldn’t be ignored. Traditional access methods would require tons of scaffolding, lengthy production stops, and much higher costs. So, the facility needed a quicker, less disruptive fix that still ensured top-notch, safe repair work.

Challenges

We were contracted to carry out a full inspection of the food manufacturing plant’s elevated ducting system while keeping disruption to the live production area to a minimum. The scope covered high-level stainless ducting, transition sections, support connections, and expansion areas. Working at height above an active facility added a layer of complexity that demanded specialist access capabilities alongside technical inspection expertise.

The Bioscan Response

Bioscan mobilised a rope-access team to conduct a detailed food plant integrity inspection of all ducting components. Our inspection of industrial equipment at height revealed fatigue cracking around stressed duct transitions, weld separation in vibration-prone areas, and powder escape pathways hidden behind insulation and support structures. These defects had been allowing fine powder to accumulate in inaccessible areas, steadily increasing both hygiene risk and fire hazard with every passing production cycle.

None of these issues was identifiable through ground-level observation alone. Without a targeted rope-access inspection, the defects would have continued to worsen undetected.

Our team used the same rope-access method to take out the damaged parts, do the confined-space welding, and fix the hygienic finish right there on the spot. No big scaffolds needed for the whole repair job either.

Outcome

The project finished with barely any disruptions to the ongoing production. Powder leakage was totally eliminated, the ducting system became intact again, and hygiene and fire risks were taken care of, too. Moreover, the facility experienced far lower access costs and much less downtime compared to what a conventional scaffolding setup would’ve needed.

Impact

This case shows how valuable rope-access skills are in food factories. They help with working at heights, cutting downtime, and keeping things clean. Bioscan made a complicated, risky fix simple and cost-effective. So, it transformed tough problems into manageable tasks.

Context

A dairy processing facility had been experiencing recurring product build-up and inconsistent CIP (clean-in-place) results within its crystallisation system. Despite passing previous visual inspections, the quality team remained concerned due to intermittent microbiological deviations and repeated cleaning inefficiencies that continued to affect production reliability.

The crystallisation tanks had been subjected to years of temperature cycling along with agitation, which made them more vulnerable to fatigue cracking at their weld joints. Standard visual checks were no longer sufficient to provide the level of assurance the facility needed.

Challenges

The requirement was to inspect the crystallisation tank internally for walls, agitator supports, weld joints, outlet transitions, and any areas that come into contact with the product. The purpose of such an inspection was to pinpoint the underlying cause of microbiological and cleaning issues at the plant.

The Bioscan Response

Our team deployed a combination of electronic crack detection, close-access visual assessment, and confined-space entry techniques to assess areas inaccessible through routine checks. The crystallisation tank defect investigation revealed multiple non-visible cracks around internal weld seams, high-stress outlet transitions, and agitator mounting points. Several areas also showed signs of product retention, surface degradation, and localised microbial harbourage risk. Each one of those problems had gone unnoticed during previous visual checks, but was nevertheless a cause of the inefficiency and microbial problems that the team was experiencing.

As a result of our findings, we conducted weld repairs, hygienic polishing, and verification of surfaces in all of the affected areas.

Outcome

The cleanability of the tank had improved considerably; product build-up incidents had reduced, and the hygienic credibility of the system was completely regained by the customer. Long-term inspection intervals were also implemented, making it possible for planned maintenance.

Impact

This case underscores the limitations of visual-only inspection in ageing dairy processing equipment. Without our non-destructive approach, the hidden defects would have continued to compromise food safety and cleaning compliance undetected. Bioscan’s dairy processing equipment inspection turned a persistent operational problem into a resolved and manageable maintenance programme.
