Well, generating a powder is a lot tougher than it seems. You can't use direct heat to evaporate the water or else you'll cook the juice. Spray drying isn't feasible on your scale. That leaves freeze drying.

You'll need vacuum pump (in a large sealer, maybe?) that can draw down to 133mbar of pressure, then you'd just have to freeze the juice and pull vacuum on it. The frozen water in the juice will sublime over time and you'll be left with juice powder.

The key is that you need a pretty hefty vacuum pump to get down to that pressure. Also, I believe you'll want to get your juice really cold (< -32C) to be below the eutectic point of sucrose (so it won't collapse giving gunk rather than a powder). You could use a low-temp freezer, but that'll run about $1500 used. A better and more creative way would be to use a dry-ice in either ethanol or rubbing alcohol. You would freeze the juice first then place it into a frozen slurry of alcohol. A 30min soak'll get you down to -50C easy.

In the end, I'd say it's a lot more trouble than it's worth. If you have $2500 burning a hole in your pocket and you really want juice powder, then by all means go for it.

is there a single machine that can do all that you discribed? and is this the method most juice/herbal extract powder manufactures use?

The demand for such a machine is so low that you will not be able to find one easily and even the few that you might find which do the job will probably be enormous, very expensive, and designed for use in a factory.
