When Was the Microwave Invented?
Who was the genius behind this amazing invention? In actuality, he went by Percy Spencer, and his creation happened by accident. During World War II, Spencer worked for a company called Raytheon, creating microwave radar transmitters.
He noticed that a candy bar he had in his pocket that day in 1945 was beginning to melt. The microwaves from the radar set he was working on were cooking the candy bar in his pocket!
Spencer discovered that the microwaves could be focused to heat food after some experimentation. Popcorn was the first food he cooked in the first microwave oven, which he invented.
Food is heated in microwave ovens using microwaves, which are radio waves with a frequency of about 2,500 megahertz. Microwaves are absorbed by water, fats and sugars and are immediately converted to heat. Because the microwaves can quickly penetrate food, they can quickly and evenly cook food.
Since most plastics, glasses, and ceramics do not absorb microwave energy, they are ideal for heating food without heating the objects nearby. This makes microwave ovens more energy-efficient than other kitchen appliances.
Spencer’s microwave cooking technique was the subject of a patent application by Raytheon on October 8, 1945. In 1947, Raytheon produced the first commercial microwave oven and called it the “Radarange.” Do you realize that it was about 750 pounds in weight and almost six feet tall? It’s true!
Also, the price was high. The initial Radarange was priced at $5,000, or more than $52,000 in today’s dollars. It would be many years before microwave ovens could be produced and sold inexpensively.
When Was the Microwave First Used in Homes?
In 1947, Raytheon released the “Radarange,” the first commercially available microwave oven. According to Raytheon, they cost between $2,000 and $3,000 and were stored in refrigerator-sized cabinets.
How Do Microwaves Work?
Inside the oven, a magnetron electron tube generates microwaves. In the metal interior of the oven, the microwaves are reflected and then absorbed by the food. Food is cooked by the vibrations caused by microwaves in its water molecules.
Microwave Safety
Microwave ovens have a poor reputation due to the microwave radiation they emit, which dates back to their invention. The World Health Organization (WHO) states that when microwave ovens are used correctly and kept in good condition, they are safe. Ovens are made to contain the radiation, which is only present when the oven is turned on and the door is closed, even though excessive amounts of microwave radiation can be dangerous. A minimal amount of radiation that may leak, primarily through the glass door, is well below international standards.
The WHO states that several nations and international standards committees have established a product emission limit of 50 watts per square meter at any point 5 centimeters away from the oven’s exterior surfaces. In reality, microwave emissions are much lower than this cap. Also, exposure decreases rapidly with distance: a person 50 cm from the oven receives about one one-hundredth of the microwave exposure of a person 5 cm away.
The main health risk associated with using microwaves is that they generally heat unevenly, which can result in undercooked or overheated portions of the food. Therefore, care must be taken and extra time must pass for the heat to equalize in the food. The primary injury that results from using a microwave oven is a burn resulting from hot food and liquids or the particles of hot food from explosions from foods, such as eggs in their shells, cooking unevenly.
The Future of Microwave Ovens
According to SciTech, many modern microwave ovens have sensors that turn off when the food is fully cooked. Samsung(opens in new tab) has developed a microwave oven that offers a variety of cooking methods. The oven can fry and bake in addition to defrosting meats and reheating leftovers. Additionally, it has a fermentation cycle that can be used to create yogurt and fresh dough.
Solid-state RF (radiofrequency) energy is used to cook food in a microwave oven made by NXP Semiconductors. Where, when, and how much energy is transmitted into the food are all under the control of the microwave oven. NXP claims the outcome is improved nutrition, consistency, and taste. With high efficiency and real-time feedback, the solid-state device enables the control of significant amounts of energy.
Other businesses, like Wayv, make portable, solid-state RF microwave ovens that can be charged using a standard plug, a car, or solar power. This particular model, which resembles a thermos, can heat up to 17 fluid ounces (0.5 liters) at a time for about 30 minutes per charge.
Microwave ovens are also gaining features to be able to connect to mobile technologies, such as the line of LG smart appliances(opens in new tab). These appliances can be remotely turned on using a smartphone or other device from any location.
