In an episode of Dirty Jobs on Discovery channel, Mike Rowe made pork rinds. If memory serves, the rinds/chips are first rendered of most of the excess fat at a moderate temperature, removed, cooled, then fried at a high temperature.
The first rendering is started with boiling water, to release the fat. The water is boiled off, leaving the lard and pork bits.
Dirty Jobs Season 4 Episode 5 - Skull Cleaner.... the cracklin' maker is in this episode.
The pork is essentially processed like "french" fries. They're cooked at a lower temperature, then flash fried to puff/crisp 'em up.

Guess my information is wrong. The Dirty Jobs episode is from season 2.
