WINERY & VINEYARD EQUIPMENT September 2015 WINES&VINES 55 PALL Scott Laboratories of Petaluma, Calif., is now the sole U.S. dis- tributor for SUPRApak filter modules from Pall. The modules are designed for high-volume wineries that need to filter large amounts wine that are being shipped out or delivered to the winery—or to prepare wines for bottling. The modules can be used to treat wines that have al- ready gone through a cross flow but have undergone some "decay" in which the colloids re- group and potentially clog pre- bottling filters. Pall filter housings can be loaded up with up to six modules to provide fil- tration at 100 gpm via "Edge- flow" that sends the wine on a longer route around the medium and not just perpendicular to the filter media. scottlabs.com Criveller Tangent Membranes RO Mini Andritz Separation MIO VIGNETO Mio Vigneto in San Ramon, Calif., distributes the M7 and M7+7 "Rocket" filters, which use a patented filtering system that employs rotating mem- branes. The supplier reports the system operates at low pressure using ceramic discs that rotate and collect particulates from the wine. Designed for small to me- dium wineries, the M7 model can filter 4,200 liters in a 15- hour cycle. miovigneto.com CRIVELLER Criveller California Group in Healdsburg, Calif., released a vertical diatomaceous earth (D.E.) filter earlier this year. The new filter has D.E. cake on both sides of the screens, making the filter smaller and more maneu- verable. Washing vertical filter elements is easier than with a horizontal filter, and discharging D.E. material is simpler because the exhausted cake is detached from the screens through vibra- tion and can be recovered through a large opening at the bottom of the unit. criveller.com TANGENT MEMBRANES Grass Valley, Calif.-based Tan- gent Membranes produces smaller filters that are designed for bench-top analysis or to pre- pare small amounts of wine for use as samples of the finished product. The company just re- leased its RO Mini, which can be used as a small-volume cross- flow filter as well as to reduce alcohol, ethyl acetate, Brettano- myces, smoke taint and other compounds. Each treatment re- quires an additional piece of equipment such as a resin canis- ter or carbon block. tangentmembranes.com
