Microporous Filter

NAVI Titanium application scenario is one of the fields with the strictest requirements for material release control and hygiene compliance in food production. High-purity food-grade sintered microporous filtration elements, with their core advantages of zero release, no media shedding, and high cleanliness, fully comply with domestic and international food contact safety standards such as GB 4806 and FDA. During beverage production, the entire process involves liquid food contact conditions. Conventional filtration materials are prone to contamination issues such as organic dissolution, fiber shedding, and heavy metal migration. In contrast, 316L high-purity stainless steel and pure titanium sintered filter elements adopt a vacuum integrated sintering process, containing no adhesives or coating impurities, and their metal ion migration levels are far below national standard limits. They can precisely intercept bacteria, colloids, fine impurities, and microorganisms in water and beverages, and are widely used in the primary liquid filtration, terminal sterilization, production of sterile air, and process purified water filtration of bottled drinking water, fruit and vegetable juices, carbonated beverages, and functional drinks. Throughout the process, they do not alter beverage flavor or cause secondary contamination, meeting the compliant production requirements for room-temperature preservation and aseptic filling of beverages.

In brewing and fermentation industries such as alcoholic beverages, vinegar, soy sauce, and yeast fermentation, the processing media are often weakly acidic, high-salt, and contain microorganisms, forming corrosive systems that can easily cause corrosion and material release from ordinary metal filter materials. High-purity non-releasing sintered filtration elements are suitable for strongly corrosive fermentation media conditions. High-purity titanium and high-quality 316L sintered materials provide excellent resistance to acids, alkalis, and fermentation liquid corrosion. During long-term contact with fermentation broth and brewing base materials, they produce no heavy metal dissolution, structural damage, or material shedding, strictly meeting food contact safety compliance requirements. During production, they can be used in processes including fermentation liquid clarification filtration, microbial cell separation, finished brewing product fine filtration, and fermentation process gas purification. They can effectively remove unwanted microorganisms and sediment impurities, improve the clarity and taste of fermented products, and prevent chemical reactions between filtration materials and fermentation media that may generate harmful substances, ensuring production safety and compliance of fermented foods.

In industrial food filtration, the selection of NAVI Titanium microporous filters directly affects food safety and compliance. Traditional filtration materials often have issues such as material release, media shedding, bacterial growth, unstable filtration performance, and short service life, making them difficult to meet high-standard food production requirements. Traditional filter materials, including filter paper, filter cloth, microporous plastics, and low-end metal filters, are usually produced through weaving, pressing, or bonding processes involving adhesives and additives. Under high-temperature, acidic/alkaline, oily, or liquid food conditions, they may cause organic substance release, fiber shedding, and secondary contamination. Their irregular pore structures and rough surfaces can also absorb residues, proteins, and microorganisms, creating cleaning difficulties and increasing the risk of bacterial growth and product contamination.

NAVI Titanium is equipped to handle non-standard and project-specific porous metal components, including parts that are not available as conventional off-the-shelf items. Development can begin with a customer's existing component, physical sample, drawing, or even a basic dimensional reference. For replacement projects, the original part can be evaluated in terms of its shape, filtration surface, mounting method, and functional sections, providing a practical starting point for reproduction or improvement. This is useful for equipment upgrades, discontinued components, special filtration assemblies, and projects requiring relatively small initial quantities.
