What is the Oenofine XL System?

Oenoflow™ XL-A System Bentonite Fining

The Pall Oenofine XL System •  Single Step Protein Stabilization and Clarification

–  Special crossflow-friendly bentonite –  Pall’s Hollow Fiber Crossflow System

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
