-3 Ceramic Crossflow Filters: Wine filtration
-Lees Ceramic Crossflow Wine Filter (starting harvest 2023!)
-2 Reverse Osmosis Filters: Volatile Acidity reduction
-Ion Exchange continuous machine: Tartaric Stabilization and Reduction of pH in juice and wine
1-We filter in ONE pass with any turbidity (NTU) or even small residues of clarifying agents. Traditional crossflows can't process more than 300 NTU and would often get clogged, needing multiple washes. That would normally require you to pre-filter.
2-We filter with Low pressure, under Inert Gas blanketing. This means a gentler push of your wine through the filter membranes, thanks to the completely automated program. We are in no hurry, so lets filter your wine the best way possible. We set the machine to filter with low transmembrane pressure. Your beverage is constantly kept under the Inert Gas of your choosing to avoid oxidation.
3-No Color Retention and No Alcohol loss. This is especially important when filtering white wines and small lots. The Ceramic is inorganic and doesn't absorb any color molecules. It doesn't absorb water either, thus after a wash cycle the machine is ready for the next filtration and there will not be alcohol dilution.
4-Automated Filtration Cycle and Wash Cycle. Our crossflows have very smart programming cycles. We can even keep filtering overnight as we monitor the machine remotely and can intervene If there are any faults recognized by the filter program. You can go to sleep, we are still working for you.
5-Extremely low wine loss. These crossflows can filter large volumes with minimal final discharge of concentrate. You can choose to let it filter till the end of the source tank automatically. In most filtrations up to 15,000 gallons we only have one final discharge of about 20gallons. That is an impressive result of 0.001% !!
6-They are Very compact and portable Filters. Almost the size of a pallet and on wheels, so we position the filter in front of your tank. No big trailers taking up space in your winery while you get ready for bottling!
Since 2014 we operate a state of the art Reverse Osmosis Filter with 8 RO membranes capable of an output of 250 gallons an hour of permeate. The permeate goes through custom built sanitary tanks with resin that traps Acetic Acid and the treated permeate is mixed back with the original wine.
1) 8 Membrane Unit Ideal for Medium to Large lots, min 500gal. Average speed 200 gph.
2) 4 Membrane Unit Ideal for Smaller Lots, average speed 100gph.
We operate since 2016 the a continuous Ion exchange Tartaric stabilization machine.
The machine can process juice or wine straight from your tank with very low pressure at a speed of 500gallons per hour. The liquid gets in contact with special resin that will trap Potassium and in smaller proportions also Calcium and Magnesium. The resulting wine has a significant reduction in pH on average as low as 2.2pH. We treat a small portion of your total blend to achieve the desired pH.
More energy and water efficient when compared to Electrodialisys.
For White and Rose' wines we achieve Tartaric stability by removing enough potassium. This is incredibly fast, gentle and wine aroma and mouthfeel is immediately integrated. We also check electric conductivity with a portable machine.
We can make up to 10,000gallons of wine cold stable in one day!
