Beverage Application Filter Press

Key features of filter presses designed for beverage applications (e.g., clarification/polishing of wine, beer, juices, cider, spirits, and similar liquids) emphasize hygienic design, product purity, ease of cleaning, and reliable solid-liquid separation while meeting food-grade standards.

Hygienic and Sanitary Construction

• Food-grade materials such as stainless steel (AISI 304 or 316) frames, sidebars, and often plates; food-grade polypropylene plates are also common.
• Sealed/gasketed chambers and closed filtrate discharge systems minimize product exposure to the environment, reduce leakage (a known issue with traditional open presses), and support high hygiene standards for wine, juices, beer, and pharmaceuticals.
• Designs facilitate Clean-in-Place (CIP) or easy manual cleaning, inspection, and maintenance to prevent contamination.
• Optional full stainless-steel enclosures for maximum corrosion resistance and cleanliness.

Filtration Performance and Flexibility

• Plate-and-frame or recessed-chamber (chamber filter press) designs, often using depth filter sheets (e.g., 400 × 400 mm) or filter cloths for clarification, polishing, or rough filtration.
• Effective removal of suspended solids, pulp, yeast, proteins, and haze-forming particles; filter aids (e.g., diatomaceous earth) may be used in some processes.
• Adjustable filtration grade by changing sheets/cloths; supports stable flow rates and high dirt-holding capacity.
• Typical operating (feed) pressures up to about 7–16 bar (100–225 psi); some beverage units rate to 15 bar. Membrane/diaphragm plates can add squeeze capability for drier cake if needed.
• Cake thickness commonly around 25 mm in dedicated beverage models; filtration area and chamber volume scale with plate size (e.g., 470–1200 mm) and number of chambers.

Operation and Automation

• Manual, semi-automatic, or fully automatic closing (hydraulic or pneumatic-hydraulic systems) and plate shifting.
• Options for PLC controls, touchscreens, automatic pump control, and safety features (e.g., two-hand operation).
• Easy cake discharge and cleaning; shuttle/plate shifters, optional cloth washing systems, and designs that reduce labor compared with older manual presses.
• Batch operation suited to beverage production scales, from small/pilot units to larger industrial systems.

Additional Practical Features

• Customizable capacity via plate size/number and modular expansion options.
• Compatibility with various filter media (sheets, cloths, papers, membranes) for different clarification levels.
• Focus on product quality: minimal impact on taste/flavor, high clarity/brightness of filtrate, and recovery of valuable liquid.
• Lower maintenance relative to some alternatives in certain setups (though enclosed cartridge systems are sometimes preferred for even lower labor/leakage in beer clarification).
• Compliance with food/beverage and pharmaceutical standards for materials and cleanability.

These presses are widely used for juice/cider clarification, wine/beer polishing or lees filtration, spirit filtration, and related processes. Specific models (e.g., AQUACHEM EC-Beverage series or sheet filter presses) are engineered expressly for hygienic beverage duty, while general industrial presses can be adapted with appropriate materials and seals. Exact specifications (area, pressure, automation level) depend on throughput, product characteristics, and required clarity. Always verify against manufacturer data and local food-safety regulations for a given application.
