Automatic Self-Cleaning Disc Stack Beer Separator – PLC-Controlled Continuous Clarification for Yeast Removal

The Automatic Self-Cleaning Disc Stack Beer Separator is a state-of-the-art centrifugal clarification system engineered specifically for modern breweries demanding continuous, unattended operation. Unlike conventional separators that require periodic shutdowns for manual cleaning, this machine features an intelligent self-cleaning mechanism that automatically ejects accumulated yeast and solid particles at precisely timed intervals while maintaining full process flow. The integrated PLC controller with intuitive touch screen HMI allows brewers to program discharge frequency, monitor real-time separation performance, and adjust operational parameters without interrupting production. Constructed entirely from food-grade stainless steel with polished internal surfaces, this separator meets the most stringent hygienic standards required in commercial brewing environments. The machine delivers consistent, high-quality clarified beer with minimal operator intervention, making it an indispensable asset for breweries producing between 500 and 12,000 liters per hour.

• Fully Automatic Self-Cleaning System: Programmable partial sludge discharge cycles eject collected yeast and solids at user-defined intervals without interrupting the clarification process. The self-cleaning bowl design maintains peak separation efficiency throughout extended production runs, eliminating the downtime associated with manual cleaning procedures.
• Advanced PLC Control Architecture: A high-performance programmable logic controller governs all operational aspects including bowl speed regulation, feed flow management, discharge timing optimization, and safety interlock monitoring. The 7-inch color LED touch screen displays real-time process data with graphical trending and supports recipe-based operation for different beer styles.
• High-Capacity Disc Stack Design: Precision-engineered conical disc stack configuration maximizes available settling surface area while minimizing bowl diameter. This enables efficient separation of yeast cells, trub particles, and chill haze precursors in a single pass with throughput rates up to 12,000 L/h.
• Continuous Clarification with Polishing Capability: The dual-stage separation zone first removes coarse solids and yeast, then a polishing zone captures sub-micron particles to deliver brilliantly clear beer ready for bright tank transfer or direct packaging.
• Comprehensive Safety and Monitoring Systems: Integrated vibration sensors with automatic shutdown protection, bowl speed monitoring with overspeed alarm, bearing temperature sensors, and seal leakage detection provide multi-layer operational safety. All alarm events are logged with timestamp for quality assurance traceability.
• Sanitary Construction Throughout: All product-contact surfaces are fabricated from SS316L stainless steel with electropolished finish to Ra ≤ 0.8 μm. The bowl interior features smooth contours with no dead zones, fully supporting CIP cleaning protocols without disassembly.
• Variable Frequency Drive Integration: Premium ABB or equivalent VFD enables stepless bowl speed adjustment from 0 to 8,000 rpm, allowing precise optimization of G-force for different yeast strains and beer styles. Soft-start functionality reduces mechanical stress and extends drivetrain service life.
• Low Maintenance Design: The gear-driven spindle assembly with oil-mist lubrication system requires only annual oil changes. Quick-release bowl hood clamps and hinged frame access panels facilitate rapid inspection with minimal tooling requirements.

This automatic self-cleaning disc stack separator is purpose-built for breweries requiring hands-free, continuous operation. Primary applications include green beer clarification immediately following fermentation, pre-filtration yeast removal to dramatically extend diatomaceous earth or membrane filter service life, and final beer polishing prior to bright tank filling or packaging line transfer. The system is equally effective for recovering yeast slurry suitable for repitching in subsequent fermentation batches, reducing overall yeast procurement costs. Its programmable discharge logic adapts seamlessly to varying solids loads encountered with heavily dry-hopped IPAs, hazy wheat beers, and traditional lager styles. Beyond core brewing operations, this separator excels in cider clarification, kombucha processing, distilled spirit pre-filtration, and non-alcoholic beverage production. The robust construction and food-grade material certification make it suitable for facilities pursuing GFSI-recognized certifications including BRC and FSSC 22000.

Each Automatic Self-Cleaning Disc Stack Beer Separator is securely packed in a custom ISPM 15-compliant fumigation-treated wooden case. Internal bracing and vibration-dampening supports protect precision components during ocean and road transport. All fluid ports are sealed and the bowl interior is nitrogen-purged to prevent corrosion during transit. The standard shipment includes the fully assembled skid-mounted separator, PLC control panel with pre-installed software and backup parameters, a comprehensive startup spare parts kit containing seals, gaskets, belts, and critical consumables, detailed operation and maintenance manuals in English and Chinese, plus an installation supervision service voucher for on-site commissioning support by our certified engineers. Quality is assured through our 60-year manufacturing heritage: each unit undergoes dynamic balancing certification, hydrostatic pressure integrity testing, a complete simulated process run with water, full-speed endurance testing, and final dimensional inspection before dispatch. All components are lot-traceable and final inspection reports are permanently archived. We provide a comprehensive 12-month warranty covering parts and workmanship, supported by our global network of factory-trained service engineers.
