Controlling the filtration process is a key element in achieving quality wines. As cartridge filtration is the last process step prior to bottling, it is critical to ensure the removal of particulates and microorganisms that can result in re-fermentation, turbidity, and off-flavors post-bottling.
The Pall Oenofil system combines years of process filtration experience, advanced automation, and superior cartridge technology to provide cold microbiological stabilization of wine with the highest level of process control, security, and brand protection.
System Software
The Oenofil wine filter system is controlled with a touch screen PLC that enables wineries to bottle their product with microbiological safety and process efficiency. The software contains working sequences utilizing Pall’s extensive experience in wine filtration resulting in consistent and repeated cartridge performance.Filtration, cleaning, sanitization, and integrity test programs can be combined for cycle programming allowing for unattended system operation. Sanitization and integrity test sequences can be programmed to run overnight, enabling the Oenofil to be production-ready at the start of each day for considerable reduction of downtime and simplification of the production start-up. At the end of each filtration, during wine recovery, the Oenofil system is pressurized with gas to reduce wine loss and increase production yield. The recovered wine can be pushed downstream to the filler or returned to the feed tank to accommodate various customer circumstances.
The flexible software can be easily adapted to interface with other bottling line equipment. When equipped with the CIP System, the Oenofil can automatically control cleaning and sanitization of the downstream piping, filler, and even the bottle washer, enabling operation independent of the winery conditions with one unit for operator interfacing.
The user-friendly control panel displays the process flow diagram and main performance parameters with the capability to emphasize different parts of the process. The trends, history, and program alarms are automatically recorded for up to 6 months providing documentation for Hazard Analysis and Critical Control Points (HACCP) and facilitating troubleshooting. Additionally, the history and integrity test results can be downloaded to a PC or connected to a printer for hardcopy records.
Specifications
The Engineered System
The Oenofil is a staged cartridge filtration system designed to be installed directly upstream of the filling line. The compact base system consists of pre-filter and final filter housings arranged in series with all piping, valves and instruments assembled and electrically connected for easy installation and short start up times. The wine process connections and sample ports are located on one side for easy access. With safety and hygiene as the main design criteria for the system, all connections are sanitary tri-clamp. The proprietary sanitary vent configuration prevents wine loss during system start up and the product contact valves are supplied with double proximity switches for maximum security.

Applications
Oenofil Concept
Optimal filtration flow rate, selection of cost saving pre-filtration and installation of membrane filters validated for removal of wine specific organisms are all critical factors for successful wine microfiltration. However, proper rinsing, cleaning and sanitization to ensure complete system hygiene are just as critical. The Oenofil automated cartridge filtration system design incorporates these principles. With Pall’s experience in filtration and understanding of how each stage is interrelated, our Oenofil system enables wineries to reduce filtration costs without sacrificing quality. Streamlining filtration, rinsing and sanitization with optimized protocols can provide up to 30% increased filter service life. Additionally, the flexible working sequences can be combined for cycle programming allowing unattended system operation for reduced labor and downtime. Depending on the individual customer circumstances, the Oenofil can be equipped with a Clean in Place (CIP) system to provide proper cleaning, sanitization and storage at the recommended flow rates, chemical concentrations and temperatures. This system, if required, can also control downstream washing and sanitization of the filler and auxiliary equipment, like the bottle washer, for complete process control via a single interface and operation independent of the winery conditions. To protect the wine quality, all Oenofil components are sanitary and all utility fluids including rinse water, steam and gas for integrity testing and wine recovery are filtered down to sub-micron levels. With systems in operation for over ten years and Pall’s extensive knowledge of wine filtration, the Oenofil system guarantees process security at the lowest possible operating costs.Performance
