Why Do Microwaves Have A Rotating Plate?

Published on 15th December, 2023.

Before we dive into the rotating plate, let's first understand how microwaves work. They work by shooting electromagnetic radiation at your food. Specifically, short wavelength radiation called Microwaves. That's where the name comes from. This radiation can excite molecules in your food, putting energy into it. Effectively, heating the food.

It is a common misconception that microwave ovens "heat" food. Heat is energy transferred solely due to temperature difference. Microwave ovens don't cook like a convection oven which uses heat. Simply put, microwaves cook food by generating kinetic energy between molecules of the food.

Role of The Rotating Plate

The rotating plate also known as the turntable, is a circular glass or plastic plate that sits on the bottom of the microwave. Its purpose is to rotate the food while it being cooked. This rotation ensures that the food is evenly exposed to the microwaves, resulting in a more even and efficient cooking.

Prevents Hot Spots

If you notice whenever you heat food, there are some spots that are still cold.The rotating plate eliminates this issue by constantly moving the food, allowing the microwaves to reach all areas of food evenly.

Promotes Even Cooking

As the food rotates, it is exposed to different areas of the microwave, which may have varying levels of intensity. Therefore, the food is cooked evenly without any undercooked or overcooked areas.

Saves Time and Energy

By cooking the food evenly, the rotating plate reduces the need for multiple cooking cycles or stirring the food halfway through. Not only does this save time but also reduces energy consumption, making microwaves a more convenient option. As the saying goes, 'Time is money.' Hence, that time can be invested in other activities like learning how to roll cookie dough here.

Moreover, they generally cook food much faster, and generate as much heat in your kitchen so you could save on air-conditioning costs during the summer.

Easy To Clean

The rotating plate is a game changer as it makes cleaning the microwave easier. As the food rotates, any spills or splatters are distributed fairly on the plate, making it easier to clean. Additionally, the rotating plate can be easily removed and washed separately reducing the hassle to clean the microwave.

DID YOU KNOW?

  1. The Microwave was invented in 1940's by accident by Percy Spencer.
  2. In a microwave oven, microwaves are made by a Magnetron.
  3. Before they became known as microwave ovens, they were called electronic ovens.
  4. Popcorn was the first food to be tested in a microwave.
  5. To efficiently heat up your food, you should place your plate near the edge because the centre of the rotating plate is the only spot that won't move when it rotates.
  6. In cake decoration, you may soften fondant by warming it in the microwave, just for a few seconds though. Otherwise, it will be come moist.

The rotating plate in microwaves plays a crucial role in ensuring even and efficient cooking. It prevents hot spots, promotes even cooking, saves time and energy, and makes cleaning easier. So the next time you use your microwave, remember to thank the rotating plate for making your cooking experience more convenient.
