J-Series Juicer GALLONS OF JUICE PER HOUR CALCULATIONS     The Sunkist Commercial Juicer can juice 10-12 gallons of juice per hour using precut citrus.  The calculation for this statement follows:   128 oz = 1 gallon 8 oz = 1 cup 16 cups = 1 gallon   3-4 medium oranges = 1 cup juice, therefore it would take 48-64 oranges = 1 gallon   Using the averages of 11 gallons of juice per hour and 56 oranges in 1 gallon:   56 oranges x 11 gallons = 616 oranges   Using 88 medium size oranges per box:   616 oranges / 88 = 7 boxes of oranges 60 minutes / 7 boxes of fruit = 8.5 minutes per box 88 oranges / 8.5 minutes = 10.4 pieces of fruit per minute 10.4 oranges x 60 minutes = 624 pre-cut oranges per hour on average   Using the above calculations and based on 10 gallons of juice per hour you could juice about 560 pre-cut oranges/hour and 12 gallons would require about 672 pre-cut oranges -
