  1. Speed Cooking Technologies • Jet-Impingement • Technical Background • Companies Involved in JIM Ovens • JIM Ovens • TurboChef

  2. Technical Background • Technical Terms • Hot Air Impinging on Food • Applications and Advantages • Temperature Profile • Nusselt Number vs. Reynolds Number

  3. Technical Terms • Jet impingement technology Technology in which jets of gas or liquid are made to impinge on a desired product for faster heat transfer or faster chemical reactions • Jet impingement oven Device used for baking and drying of food materials using jets of hot air at velocities (20-40 m/s) to impinge on the product • Jet-impingement Microwave (JIM) Oven Ovens operated in jet-impingement mode and microwave mode either individually or in combination.

  4. D FOOD PLATE Hot Air Jet-Impinging on Food Jet of hot air impinging directly on food

  5. Applications and Advantages • Applications • Baking for pizza shells, crackers, matzo, cookies • Toasting for ready-to-eat cereals • Roasting for coffee beans • Advantages Over Other Technologies • Efficient heat transfer • Energy efficient • Uniform heating • Better moisture retention in food
