Why Do We Need a Turntable in Microwaves?

The microwave, invented by accident in 1945, has become a staple in American households. According to the U.S. Census Bureau, a staggering 97% of American homes own a microwave.

There are countless reasons microwaves are considered essential, from effortlessly reheating and defrosting to cooking quick meals like mug cakes. But did you know that the turntable serves a crucial function?

What is the function of the turntable in the microwave?

While many understand how microwaves work, questions often arise about the turntable – that circular plate that rotates while your food warms up.

The turntable is a vital component of the microwave. This appliance cooks using electromagnetic microwaves, minute waves with wavelengths ranging from 30 centimeters to 1 millimeter. These microwaves bounce around inside, interacting and generating the necessary warmth for cooking.

The turntable's primary job is to distribute heat across the entire food surface. Its rotation prevents cold spots, eliminating the need for frequent manual stirring.

Manufacturers who forego the turntable may use a fan-like device in the oven walls to even out the heat. This device directs microwaves in different directions, eliminating potential cold spots that could harbor bacteria.

Can I use a microwave without the turntable?

Yes, you can. Microwaves without turntables can still function, though less efficiently. Without a turntable, there may be uneven heat distribution throughout the food item.

If you lose or decide to remove your microwave's turntable, consider using a Flatbed Digital Microwave. This alternative technology evenly heats food without the need for a turntable.

Why do some microwaves not spin?

Microwaves without turntables remain functional, employing alternative methods for even heat distribution. Some come with stirrers or mixers for manual stirring between cooking times, while others utilize multiple fans to blow waves in various directions, ensuring uniform cooking.

Summary

Turntables play a vital role in microwave operations, ensuring even heat spread and preventing cool air pockets that could harbor microbes. Although newer methods exist, the turntable remains the norm in most microwaves.
