Bio-Food Pharma

Typical Applications

The Pharmaceuticals and Food & Beverages manufacturing process demands extremely high levels of cleanliness, and the quality of filtration technology directly impacts the final quality of the drugs. They are applied in various stages, from raw water treatment and clarification, sterilization, and decolorization during the production process to fine filtration of the final product. This ensures that pharmaceutical products meet strict pharmacopoeia standards to protect patient health and that food and beverages meet consumers' expectations for taste, appearance, shelf life, and food safety. Our filters meet the highest demands as regards product quality, purity and process reliability.

Fermentation engineering applications

Pretreatment and clarification filtration

Large particle removal: Prior to fine filtration, multi - media filters (e.g., sand filters and manganese sand filters) are employed to eliminate suspended solids, sediment, and colloids from raw water or raw liquid.

Reducing downstream load: In biopharmaceuticals, depth filter cartridges containing diatomaceous earth or cellulose trap cell debris and protein aggregates via their complex internal channels.

Application scenarios: Fermentation broth extraction, preliminary clarification of traditional Chinese medicine extracts.

Pretreatment and clarification filtration

Sterilization and terminal fine filtration

Sterilization - grade membrane filtration: Uses microporous filter membranes with a precise physical pore size of 0.22 μm (such as PES or PVDF) to physically "trap" bacteria on or within the membrane surface.

Decolorization and deodorization: Employs activated carbon as a physical adsorbent medium to remove organic pigments, odors, and some endotoxins from the liquid.

Application scenarios: Terminal filtration of injectable solutions, decolorization and purification of oral solutions.

Sterilization and terminal fine filtration

Clarification and filtration of beverages and alcoholic drinks

Beer Filtration: Diatomaceous earth filters or candle filter presses are used to remove yeast and cold haze after fermentation, yielding a clear and transparent beer with enhanced flavor stability.

Juice/Fruit Wine Clarification: Cellulose filter sheets or microporous pleated filter cartridges are utilized to remove pulp fragments and plant fibers, preventing sedimentation after packaging.

Liquor Purification: Physical media filtration effectively removes high - boiling point fatty acid esters from liquor (preventing turbidity at low temperatures) while retaining the original aroma of the spirit.

Clarification and filtration of beverages and alcoholic drinks

Refining of edible oils and condiments

Edible oil dewaxing and degreasing: At the end of edible oil refining, a physical filter cake layer intercepts precipitated waxes, ensuring the oil remains clear and transparent even at low temperatures.

Syrup and honey filtration: Due to the high viscosity of syrup, metal mesh or high - flow stainless steel filter cartridges are typically used to physically intercept black spots, impurities, and undissolved particles.

Soy sauce and vinegar: Filtration removes suspended solids and microorganisms from the brewing process, ensuring the product does not become cloudy during its shelf life.
