When beer is filtered, the filtration speed is directly proportional to the pressure difference and filter area, and inversely proportional to the fluid viscosity and filter media thickness.
Types of filter materials
1. Metal filter screen or textile: There are different types of metal screen, crack screen or special-shaped metal wire and metal or textile braid installed in parallel on the candle diatomaceous earth filter.
2. Filter plate: The filter plate can be made of fiber, cotton, diatomaceous earth, perlite, fiberglass and other materials. There are many types of filter plates to meet the needs of different filtration precisions, up to sterile filtration.
3. Membrane materials: Membrane filtration is increasingly used in applications. There are many materials for making membranes, such as polyurethane, polypropylene, polyamide, polyethylene, polycarbonate, acetate and other materials.
