Cross-flow filtration of fruit juice

 

Figure 10.2. Yearly black currant production at Vallø Saft


*
6680 ton berries
668 ton (10%) loss at the press
6012 m3 left
5410,8 m3 (90%) top-juice to the centrifuge
601,2 m3 (10%) sediment to the vacuumfilter
270,54 m3 sludge (5%) from the centrifuge to the vacuumfilter
871,74 m3 total to the vacuumfilter
To use in the following calculations the loss of juice in the vacuumfilter is considered negligible.
2104,2 m3 (35%) to the pressurefilter
3907,8 m3 (65%) to the ultrafiltration unit
