As clanad says, the squeezed orange juice is concentrated by evaporation, usually at reduced pressure. This means the boiling point of the OJ is reduced, and results in a less 'cooked' flavour, and minimise the loss of 'volatiles', (the complex molecules in the juice and oils of the orange that give it its flavour)
The concentrated form makes it cheaper to transport, as you are not shipping excess volumes of water across the globe, and this water can simply be 'put back in' when required. (ie at the packaging plant).
Various additives and flavour enhancers are used at this stage to mask the 'cooked' taste and make it seem 'fresher' to the palate.
Frozen Concentrated Orange Juice (FCOJ) is a major commodity (like coffee, cocoa, sugar etc) traded on all the world's commodity exchanges.
