Stay Away From Microwave Radiations The Food and Drug Administration (FDA) monitors each and every microwave oven that are being sent out for commercial use to ensure that the amount of radiation they emit are far below the level that is known to harm people. The limit is 5 mill watts of radiation per square centimeter at a distance of approximately 2 inches from the oven's surface. Cold spots or uncooked sections might still be evident because of the uneven way the microwaves enter the oven. Because of the irregular flow of waves, the food will also absorb the heat unevenly. Defrosting Food that was readily bought out from the supermarket's freezer must be removed from its plastic wrapper first before putting it inside the oven. When dropped down, there can be a lot of harms to be brought about. The power supply or switches can also lead to damages. Breakages, dents, scratches, and the likes are also among the deleterious effects that the device can suffer from. Come to think of it, the microwave oven has already become an integral part of your entire family and hence needs to be cared for. If you re going to place it on the kitchen countertop, compact or portable microwave ovens are ideal. Power Consumption You can cook faster on units with higher wattage. Most microwaves available in the market come with power rating ranging from 600 to 1200 watts. Type of Microwave Unit There are two main types of microwave oven the countertop and built-in microwaves. Controls Newer microwave ovens have buttons for operating functions. If you've been to a convenience store, chances are you've already seen one of these. The buttons are very intuitive due to the icons that tell you outright its respective functions. If you prefer the old fashioned way, you can always choose the ones with dial control. They are also widely available in most home improvement and appliance stores. What makes them different from each other is the way heat is circulated inside the oven. In a convection microwave oven, there is a fan that blows hot air to ensure heat is dispensed evenly. Conventional Ovens Almost all American kitchens have modern conventional ovens.
