Inside the Food Factory S01 E03 Snacks

Follow host Gregg Wallace to the food factories of Europe as he examines the amazing machines that mass-produce our favorite snacks. From the Birds Eye plant in England, where they peel, mash, and form nearly a million waffle potatoes a day to the Roncadin factory in Northern Italy, where they fire up 370 pies a minute, we reveal how our insatiable appetite for a good snack has led to the invention of some of the craziest and most ingenious machines ever built, including traveling ovens, cheese waterfalls, "robo-cows," and more.
