Winery Equipment Testimonial

Ryan and I worked together at Justin Winery for five years and have known each other for ten. While at Justin, Ryan was passionately interested in the wine making process, could fix about anything and was totally dedicated to making the winery a success. He has taken that dedication to Vintner Vault and became a major player in the winery supply business in just a few years. Jeff Branco, former VP and Winemaker Justin Winery jeff@coitliquor.com

Flow rate determination of Pad Filter
Pads: 40 x 40 cm = 1.5 square feet of filtering surface area per pad.
Determine volume of wine and time to filter tank.
 
Polish pads
Maximum flow rate of (30) gallons per hour per pad (=20 gph per sq ft)
 
Example:
3,000 gallons to be polish filtered in (4) hours = 750 gals per hour
750 gals/hr / 30 gph/pad = 25 pads needed for the filter
Polish pads are plugged when differential pressure is (30) psig.
 
Polish Pad Filtration Equation:
(Total Gallons to be filtered / hours to filter tk) / (30) = no of Pads
 
Sterile pads
Maximum flow rate of (15) gallons per hour per pad (=10 gph per sq ft)
Example:
1,000 gallons to be sterile filtered in (4) hours = 250 gallons per hour
250 gals/hour / (15) gals/hr/pad = 16.7 pad or 17 pads needed for the filter
 
NOTE: STERILE PAD DIFFERNTIAL PRESSURE TO BE LESS THAN (15) PSI OR FILTRATION IS NOT STERILE.
 
Sterile Pad Filtration Equation:

(Total Gallons to be filtered / hours to filter tk) / (15) = no of Pads
