PTFE (polytetrafluoroethylene) membrane pleated filter cartridges, with their non-toxic, odourless properties, high chemical inertia, exceptional filtration precision, and ease of cleaning and sterilisation, align with food manufacturing hygiene and safety standards. They serve as critical filtration components for safeguarding food purity, taste, and shelf life, finding extensive application across multiple food processing sectors including beverages, dairy products, and condiments.

Their application is most prevalent in beverage production. Bottled water, fruit juices, and tea beverages all undergo filtration through these cartridges to remove impurities, microorganisms, and colloidal particles from source water. Simultaneously, they intercept pulp residues and suspended solids in fruit juices and tea liquids, preventing turbidity and sedimentation. This ensures the clarity and original flavour of beverages, with no leachables affecting taste.

In dairy processing, it filters fresh milk and clarifies yoghurt fermentation liquids, effectively removing impurities and contaminants from raw milk while preventing microbial contamination during fermentation to enhance product purity. Compatible with high-temperature sterilisation processes, it enables repeated use, thereby reducing production costs. For condiment production, it filters sauces and vinegars, eliminating fermentation-derived sediments to improve clarity and extend shelf life.

Furthermore, it is employed in filtering food additives and edible oils, intercepting impurities and foreign matter while removing colloidal substances from oils to ensure compliance with food hygiene standards. Its pleated structure combines high throughput with extended service life, meeting the demands of continuous food production while safeguarding food safety and product quality throughout the manufacturing process.
