WINERY & VINEYARD EQUIPMENT 54 WINES&VINES September 2015 PRODUCT FOCUS Filters Several new filters on the market can better handle high-solid lees and juice to enable wineries to save more wine, while other firms have new, specialized filters for specific applications. Prices vary based on the filtration medium or technology as well as capacity. By Andrew Adams DIEMME The MicroFlex from Diemme is automated direct membrane fil- tration that can be applied to fin- ished still, sparkling or clear juice. Controlled by patented software called "IntelliFlex," the system filters at a rate of about 100 to 500 liters per hour per cartridge. Unlike cross-flow fil- tration, the system does not re- quire recirculation or back flush, provides a higher quality filtrate, uses less energy and places "less stress" on the wine, according to the manufacturer. A self-priming pump ensures an isobaric filtra- tion cycle and also powers the automated wash cycles that re- generate the cartridges. The Mi- croFlex is available with 12, 24 and 48 cartridges. The 24 and 48 models are completely automatic for filtration and wash cycles. Available in the United States through Collopack Solutions. collopack.com ANDRITZ SEPARATION In 2013, Andritz Separation re- leased its "dynamic" cross-flow filtration units. The filter em- ploys overlapping rotating disks that create differential speeds to "generate a cross flow without requiring a pump to circulate the slurry and without any circula- tion line at all." Andritz, which has a U.S. office in Arlington, Texas, describes the new units as "a plug-and-play" solution for recovering lees or fining wines. andritz.com. TMCI PADOVAN Manufacturer TMCI Padovan claims its Dynamos filters are the first dynamic rotary cross- flow filters with a new "cali- brated back-wash system" that enables them to filter wine, lees, juices and concentrates. The fil- ter employs self-cleaning, cross- flow disks that can filter for up to 72 hours and recover up to 95% of usable wine. The filters are available in 1 m 2 to 80 m 2 capacities and custom size. Dis- tributed through American Tar- taric Products in Windsor, Calif. americantartaric.com DELLA TOFFOLA Windsor, Calif.-based Della Tof- fola USA released its OMNIA ce- ramic cross-flow filter in the United States in 2014. The new filter provides a juice-recovery rate of more than 90% and can be used to separate wine from lees as well as juice from solids and to extract clean juice from cold-settled lees, according to the manufacturer. The ceramic filters are up to five times more durable than organic mem- branes, according to Della Tof- fola. The supplier also reports that the filter takes wines with a turbidity of 25 to 1,000 NTU (nephelometric turbidity units) down to 0.00 NTU. dellatoffola.us TMCI Padovan Dynamo60 Diemme MicroFlex Della Toffola OMNIA
