In the food and beverage industry, sintered metal filters and porous spargers have food grade safety properties, supporting repeated CIP online cleaning and SIP steam sterilization. They not only achieve high-precision and stable filtration, but also evenly distribute gas and liquid, fully adapting to various key production processes such as material clarification, sterile sterilization, sterile gas supply, beverage carbonation, fermentation oxygen supply, etc.

I. Gas Distribution

The porous distributor evenly distributes gas/liquid into 0.1-2 mm microbubbles/droplets, increasing the gas-liquid contact area (3 times+), enhancing mass transfer, and achieving uniform distribution.

1. Core Materials & Advantages

Materials: Mainly 316L stainless steel (available with third-party FDA and food-grade certifications); titanium alloy for special scenarios; PTFE for corrosive environments. Aperture: 0.1–100 μm, porosity: 30%–45%.

Key Advantages:

• Sanitary & sterile: No particle shedding, no secondary pollution, acid and alkali resistant (pH 3–11).

• High temperature & pressure resistance: Continuous service temperature ≤600℃, pressure resistance 1–3 MPa, compatible with pasteurization, CIP and SIP processes.

• Reusable & renewable: Regenerable via backwashing, ultrasonic cleaning and chemical cleaning, service life is 5-10 times longer than ordinary filter elements.

• Stable filtration accuracy: porous structure with uniform aperture, free from deformation during long-term operation.

2. Main Applications

• Beverage carbonation (CO₂): Micro porous aeration, CO ₂ dissolution efficiency+40%, time -30%, fine and long-lasting bubbles, and good taste.

• Fermentation tank oxygen supply (beer): uniform microbubble oxygen supply, stable dissolved oxygen, uniform fermentation, and shortened cycle.

• Nitrogen/carbon dioxide gas seal: evenly distribute gas on the top of the tank to isolate oxygen, prevent oxidation and deterioration, and extend shelf life.

• CIP/SIP cleaning distribution: uniform spraying/steam distribution inside the tank, no dead corners, thorough cleaning and sterilization.

• Liquid distribution (mixing/reaction): Syrup/mixing solution is evenly distributed, mixed evenly, and the ingredients are stable.

II. Filtration Applications

1. Alcohol (beer/wine):

• Beer: Remove husk residues from wort and hop residues from fermentation liquid to extend shelf life.

• Wine: Separate pulp and pectin from grape juice.

2. Fruit Juice & Soft Drinks

• Clarification filtration: Remove pulp fiber, pectin and starch to improve clarity and luster.

• Syrup & sweet liquid filtration: Eliminate carbon black and impurities, prevent crystallization and stabilize flavor.

3. Modified starch:

Recover 0.5μm starch particles, meet pollutant discharge standards and eliminate sewage tanks.

III. Maintenance & Regeneration Methods

1. Online CIP: 85 ℃ hot alkali + clean water circulation flushing;

2. Offline cleaning: 5% acid washing + ultrasonic cleaning + pure water rinsing, dried and reused;

3. Sterilization: Steam sterilization at 121 ℃ for 30 minutes, suitable for sterile conditions.
