What is the Oenofine XL System?
The Pall Oenofine XL System • Single Step Protein Stabilization and Clarification – Special crossflow-friendly bentonite – Pall’s Hollow Fiber Crossflow System Oenoflow™ XL-A System
Bentonite Fining
Oenofine XL System
Traditional Protein Stabilization
• Bentonite Fining – Manual addition/mixing in treatment Tank – Added during racking or recirculation
• Strengths – Technically Effective – Proven
• Weaknesses – Large lees volumes (2-10%) – Settling before downstream processing – Labor Intensive
Filtration after Stabilization
Traditional Methods • Diatomaceous Earth Filtration • Sheet Filtration Modern Method • Crossflow filtration – – – – – – –
Eliminates use and disposal of filter aids More consistent filtrate quality Higher wine yields Low water and energy consumption Less labor and handling More hygienic operation Lower operating costs
Filtration after Stabilization
• Crossflow filtration weaknesses – Membranes can loose integrity from bentonite exposure – Irreversible membrane fouling from high bentonite concentrations – Many crossflow suppliers forbid use with suspended bentonite
Asymmetric membrane
Why Oenofine XL Technology?
• All the benefits of crossflow filtration • Eliminates weaknesses previously mentioned • Plus: • • • • • •
Reduced downtime Increased speed to bottle Increased Tank Turnover/Capacity Reduced wine lees Fewer wine movements Increased wine recovery

Oenofine XL System Operation
• Bentonite lab trials to determine dosing concentration – BXF-FINE – BXF-FINE ACTIVE
• Operator selects wine stabilization • Operator enters dosing concentration and bentonite solution dilution factor – Automatic addition considering system flow rate – Manual addition according to customer
Oenofine XL System Operation
• Dosing rate is automatically calculated and controlled based on the system flow rate • Cycle Programming Capability • Clarification without stabilization is possible for flexibility to use the system at different production stages • Final Concentration (LCV) and Tank Distribution System (TDS) do not function in stabilization mode
