In the restaurant we own 2 of these drum sieves

they are available at resteraunt supply stores or on the web.
Ours are 16" across we can set them over the 30 qt mixing bowl and sift directly into what we are mixing. If we sift onto parchment paper we just flip it over so there is space for the flour to fall through onto the paper. They can handle large jobs, don't have small pieces that rust or break and can be cleaned by running through a commercial dish machine.
Bonus : When the screen wears out you can buy a new screen rather than replacing the entire sifter.
At home I own the same sifter as ChefDave11 and it does the smaller jobs just as well.
