Infra red is just another way of saying thermal energy, which is another way of saying heat. An IR cooker works pretty much the same way as a toaster does, heating the food by putting it near rods/wires heated red hot.
IR is heat in the form of electromagnetic radiation. The IR is absorbed by the food causing it to become hotter, eventually becoming cooked (or finally burning).
The Easy-Bake oven toy uses mostly the IR emitted from a 100W lightbulb to bake its small thin "cakes".
Infrared radiation, also commonly known as "heat".
Yes. But you wouldn't want to be near it. Yikes!
so the heat can get in it
No, it's contagious.
by a fire
Yes you can cook with infrared safely as long as it produces a sufficient amount of heat in order to properly prepare your food. The infrared waves don't actually effect the food, they just cause heat to be generated. The heat cooks the food.
Food your would normally cook on your grill can also be cooked on a infrared gas grill. Food such as steaks, chicken, and ribs can all be prepared with this type of grill.
it only heats. take a toaster for an example; the shiny surfaces inside the toaster reflect infrared rays from the heating elements away from the case. the suface of the bread absorbs infrared rays and gets hot.
Infrared barbecue grills use radiant heat to cook food, not radiation. It cooks meat very quickly and thoroughly, and the only risk you'll encounter in the beginning is burning food, the time you get accustomed to it.
Microwave ovens employ microwave radiation, which is lower in frequency than infrared radiation, to generate the heat in the food they cook. They don't use infrared radiation per se.
Infrared barbecue grills use the direct exchange of infrared energy to cook items placed on the grill. This means that it is one of the few grilling methods that will not be affected by having the cover of the grill opened at all times. This is because the air around the food is not being heated by the infrared elements. Using an infrared grill with the cover open can help to keep food from drying out and burning.
Most ovens bake stuff using two distinct physical phenomena simultaneously: Infrared radiation and convection. both originate from the red hot heating coils/element. In the Infrared oven (Such as some very cheap versions of toaster ovens) there's only one or two infrared sources. these heat using radiation, but there is comparatively much less convection- based heating
The infrared heat is transferred to the food by radiation.
In one way or another, Infrared cannot be controlled, I say this because if you expose something to Infrared for too long, that thing could burn. Therefore Infrared is too intense, to defrost food (a delicate thing). This is most probably why Infrared would not be good for defrosting food.
Other grills, whether gas, charcoal, or wood, give off infrared heat. An infrared grill, however, is designed to give off a much higher amount of heat than the others. It also doesn't have nearly as much air circulation as it radiates heat, which allows the food to retain more moisture. It also cooks faster because of the higher temperatures.
the light you use to heat food is an examle of a infrared wave.
