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
