Stainless Steel Sanitary Quick-install Filter For Beer Brewing

The working principle of stainless steel sanitary filter is to remove impurities in the fluid through physical interception or adsorption to achieve fluid purification. First, the fluid enters the housing from the filter inlet. When passing through the built-in filter element or filter screen, larger particle impurities are intercepted by the filter screen or filter basket, and fine particles rely on the microporous structure of the filter element for deep filtration. As the filtration proceeds, impurities gradually accumulate on the surface of the filter screen or filter element, causing the pressure difference to rise. When the pressure difference reaches the set value, it is necessary to clean or replace the filter element to restore the filtration efficiency. Some self-cleaning filters can clean the filter screen by backwashing or automatic scraping without stopping. Finally, the filtered clean fluid flows out from the outlet, ensuring the stability of downstream equipment and production processes, while improving product quality and production efficiency.

The options of stainless steel sanitary filter include:

Filter element type: stainless steel filter element, PP cotton filter element, activated carbon filter element, etc., suitable for different precision requirements.

Interface mode: quick installation (quick installation), thread, flange, suitable for different pipeline systems.

Filtration accuracy: optional from micron to nanometer to meet different filtration requirements.

Drainage method: manual drainage, automatic drainage, self-cleaning function.

Sealing material: silicone, fluororubber, EPDM, suitable for different media and temperatures.

Structure type: Y-type, T-type, basket type, bag type, precision type, suitable for different application scenarios.

Surface treatment: mirror polishing, matte treatment, improve corrosion resistance and cleanliness.

• The surface of the stainless steel sanitary filter is treated with electrolyte corrosion to form an ultra-smooth passivation layer, and the micro-roughness can be controlled below 0.25μm, which is more corrosion-resistant than traditional mechanical polishing.
• The stainless steel sanitary filter is welded by high-energy laser in an inert gas environment, and the weld is smooth and non-oxidized, avoiding intergranular corrosion caused by traditional welding.
• The filter element of the stainless steel sanitary filter is sintered layer by layer by metal fibers of different pore sizes to form a three-dimensional filter matrix, rather than a traditional single-layer screen.
• The internal flow channel of the stainless steel sanitary filter adopts a spiral guide or Venturi structure, so that the fluid generates high-frequency eddy currents when passing through, automatically flushing the filter surface and reducing particle deposition.
• The surface of the stainless steel sanitary filter is treated with nano-coating to make the water contact angle >150° or the oil contact angle >120°, which can separate the water-oil mixed system in a targeted manner.
• The stainless steel sanitary filter integrates an air pressure or diffusion flow test interface, and can perform bubble point test or forward flow test without disassembly to verify whether the filter element is damaged.

Stainless steel sanitary filters are widely used in the following industries: Biopharmaceuticals: aseptic filling, vaccine production, interception of microorganisms and particles. Food and beverages: milk and juice filtration to ensure taste and safety. Dairy products: degreasing, homogenization, removal of impurities and fat globules. Beer brewing: yeast separation to ensure clear and stable wine. Cosmetics: essence and emulsion filtration to improve product purity. Electronics industry: ultrapure water preparation, removal of nano-scale particles. Chemical industry: highly corrosive liquid filtration, acid and alkali resistance.
