In 1854 Schumacher began grinding oats in his Akron, Ohio, store, using a hand mill similar that used to grind coffee beans. Schumacher then opened the German Mills American Oatmeal Company, grinding the oats between two rotating millstones.  The ground oats resulted in a cooked oatmeal that was pasty and lumpy.<\/p>\n\n\n\n<p>Asmus J. Ehrrichsen, one of Schumacher&#8217;s employees, replaced the millstones with rotating knife blades. This substantially reduced the amount of residue and produced a more uniform meal.  Unfortunately, meal of uniform taste and flakiness. While producing a better product, Ehrrichsen&#8217;s invention still resulted in significant waste, prompting Schumacher three years later to purpurchase porcelain rollers from England. Not only did the rollers eliminate waste, but they produced a meal that could be cooked in as little as one hour.<\/p>\n\n\n\n<p>An interesting side note is that in nearby Ravenna, a mill owned by Heston and Seymour, was also selling steel-cut oats, but instead of selling them in bulk, they packaged them in paper boxes with the printed cooking directions, calling their product &#8221; printed on the outside. They called their product &#8220;Quaker Oats.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>On November 30, 1875, Asmus.J.
