Blue Detectable Sealings for Advanced Food Safety
Step inside any modern food manufacturing facility and you’ll find a critical operation at its heart: the efficient, hygienic conveyance of powders. Manufacturers often need to move flour, sugar, spices, or specialty ingredients. They use different types of equipment to move powders. This includes bucket elevators, screw conveyors, and pneumatic conveyors. Each conveying technology share a common enemy: the risk of foreign body contamination due to worn or damaged sealings, gaskets and other parts
The Hidden Challenge: Contamination from Seals and Gaskets
In industry, contamination from seals, gaskets, or fragments from other parts, is a major threat to product quality. Conventional seals are often made from food-grade polymers. They can wear down from abrasive powders, strong cleaning cycles, and mechanical stress. Over time, these seals can degrade, crack, or break, releasing small fragments into the product stream.
Traditional seal fragments often resemble the powders they aim to protect. This can make visual checks and standard detection methods fail. As a result, manufacturers may face expensive recalls and harm to their brand.
Quality assurance teams, food safety managers, and plant operators must therefore implement robust food contamination control to protect both consumers and company reputation. Regulatory compliance frameworks such as HACCP demand effective seal fragment detection and foreign body contamination prevention, making this an urgent operational and compliance issue.
The Solution: Blue Detectable Sealings for piFLOW®f Conveyors
Piab’s new blue detectable sealings for the piFLOW®f vacuum conveyor directly address this industry-wide challenge. Designed specifically for the food industry, these innovative seals combine two powerful detection mechanisms:
- Vision inspection: The bright blue color is easy to see against most food powders. This helps quickly find any foreign body contamination during manual and automated checks.
- Magnetic filter compatibility: These seals have iron particles. This means standard magnetic traps can find even small pieces, like 2mm. This is a good practice in food safety as it helps catch unwanted metal or metal-detectable contaminants.
Vacuum conveying, especially with piFLOW®f, already offers significant advantages for food manufacturers. The enclosed transfer reduces contamination risk, gentle handling prevents product degradation, and easy cleaning supports quality assurance. Now, with blue detectable sealings, manufacturers get more protection for food safety.
The new blue sealings are available as variants for Module Seals for piFLOW® i, f and Bottom valve seals for piFLOW®i, f.
The Manufacturer’s Advantage
These new detectable sealings represent a major step forward in risk reduction and operational efficiency. By combining vision inspection and magnetic filter compatibility, the seals help meet regulatory requirements. This makes it easier to pass audits and assures customers about product safety.
They simplify daily operations, reduce potential for recalls, and bolster brand reputation. They also support a robust quality assurance and food contamination control, even when handling abrasive powders.
In a market where trust is key, Piab has found a way to meet the strictest requirements. These detectable sealings help manufacturers follow food safety standards. It gets easier to deliver safe, high-quality products every day.
