Microwave power How it works The Speed Oven contains a highfrequency tube called a magnetron. It converts electrical energy into microwaves. The microwaves are then distributed evenly throughout the metal sides of the oven interior to reach the food from all sides. In order for microwaves to reach the food, they must be able to penetrate the cooking container being used. Microwaves can penetrate porcelain, glass, cardboard and plastics, but not metal. Do not, therefore, use dishes made of metal, or which contain metal, for example in the form of gold or silver trim. The metal reflects the microwaves and this could cause sparking. The microwaves cannot be absorbed. Microwaves pass through a suitable container and find their way directly into the food. All food contains moisture molecules which, when subjected to microwave energy, start to oscillate 2.5 billion times a second. The friction caused by this vibration creates heat, which first starts developing around the outside of the food and then slowly penetrates towards the center. The moisture, fat and sugar content of food will affect the speed at which it is cooked. Advantages - Food can generally be cooked with little liquid or oil. - Defrosting, heating and cooking is faster than using a conventional oven. - Nutrients, such as vitamins and minerals, are generally retained. - The color, texture and taste of food are not impaired. Microwaves stop being produced when the program is interrupted or the door is open. While in operation the closed, sealed foor prevents microwaves from escaping the appliance.
