the commerical guys do it - e.g. potato chips are never greasy

I don't know, but centrifugal force like a salad spinner might do
for home use. Unfortunately you'd want to do it immediately
after the chips come out of the oil, while they're still hot, and
a plastic salad spinner might not tolerate the temperature.

A small hobbyist honey extractor might work. They're made
out of metal, and have two metal screen baskets. By cranking
a handle, they can be spun at high speed. Normally, a honey
extractor is used to extract honey from honeycombs after the
wax caps have been cut off with a hot knife.
