Food & Beverage Processing Applications
Quick answer: Food and beverage plants use filter presses in two ways: to clarify a liquid product (juice, wine, edible oil, soy sauce, vinegar, syrup, enzyme broth), where the filtrate is the product and a plate and frame press with 304/316L stainless plates and food-grade cloth is usual; and to dewater by-products and wastewater sludge (spent grain, bleaching earth, DAF sludge, starch and gluten), where a chamber or membrane press gives the driest cake. Cloth and plate material are chosen for hygiene and cleanability first, then for particle size.
Key figures at a glance
- Plate materials: polypropylene for by-products; 304 or 316L stainless steel where the liquid is the product
- Cloth: food-contact polypropylene or polyester, monofilament for clarity, multifilament or felt for fine solids; see food-grade filter cloth
- Typical plate sizes: 320–800 mm for product clarification, 800–1500 mm for by-product and sludge dewatering
- Filter aid (diatomite, perlite) pre-coat is common for polishing filtration of oils and juices
- Cleaning: cloth wash-down and, for stainless units, open frames that can be hosed or CIP-connected
