This ingenious loop kicks off when you use Extruder's sacrifice ability to feed it a Food, which sets Nuka-Cola Vending Machine's triggered ability into motion. Because Academy Manufactor is sitting on your battlefield ready to upgrade every token creation, sacrificing that single Food actually replaces it with a windfall of a Clue, a Food, and a Treasure. You can then feed that newly generated Food right back into Extruder, growing your creatures with endless +1/+1 counters while generating an infinite supply of artifacts, tapped Treasures, tapped Foods, and tapped Clues.
