How is single strength fruit puree converted to puree concentrate without using the process of evaporation?

I don't know how it is actually done in the beverage industry, but it COULD be done using a centrifuge method. This would separate all the solids, and push them to the bottom of the container, leaving a liquid of water on top, which could then be removed, thus concentrating the puree. This method would not be very effective for concentrating down dissolved components, just solid ones (for instance, if you had sugar dissolved in water, centrifuging it would do little (something, but not much), but if you have a puree of fruit, it will be very effective at separating and and all pulp from the liquid).
