microwave

1. magnetron

   • creates short radio waves called microwaves
   • travel through a wave guide
     • a wave guide is a rectangular metal tube that goes to a fan light device
       • the fan scatters the waves around the metal interior the oven
       • the fan in the microwave is called a Stirrer
     • the waves bounce to wall to wall
       • the food water molecules are dipolar
         • dipolar: positive electrical charge at one end and a negative charge at the other
         • the magnets in the waves and the molecules move back and forth creating friction which creates heat

2. thermal ovens

   • heating elements on the top and bottom
   • third heating element; A fan
     • the fan sucks in air from the oven chamber and back in to the oven
   • food done in these overs are done 25% faster than regular ovens
     • time can really add up with food that takes longer
     • cooking turkey in a thermal oven can save you about an hour
   • food cooks more evenly
     • example; cookies baked in a regular oven the bottom and the top are cooked before the middle rack and in the thermal oven its all cooked evenly
   • its heats up more easy and keeps heat, hotter than normal ovens
   • Can cook food on any rack due to evenly heat spread in the thermal oven
   • no cold or hot spots
   • use a more shallow or low sided pan when cooking so it can cover more evenly
   • use bake wear that is bright or light
   • with all the air moving around it eliminates all cold or uneven air
