Summary

The authors recall some theoretical aspects of distillation using hydrophobic membranes and describe their experimental study of orange juice concentration, using such a membrane with 25 deg C on the warm side and 0 deg C on the cold side. Juice concentration increased by 16% after 8 hours. The liquid flow rate through the membrane was 2.8 liters per square meter and hour, whereas it is 10 liters through reverse osmosis membranes in current practice. Nevertheless, the advantage of hydrophobic membrane and refrigeration is that juice concentration does not require heating. J.G.
