The invention and evolution of the countertop microwave oven is a fascinating journey. The first microwave ovens were invented by Percy Spencer in 1946 during his work on radar technology at Raytheon, a manufacturing company. He found that an electromagnetic wave, now known as a microwave, could cook food.

However, these early microwave ovens were bulky and too expensive for home use. It wasn’t until 1967 that the first countertop, domestic microwave oven, the Amana Radarange, was introduced to the market by Raytheon. Technological advancements in design and operation over the years have since made these appliances more compact, efficient, and affordable.

Types of Countertop Microwave Ovens

Countertop microwave ovens can be organized into different categories based on several factors such as size, power consumption, and functionality.

Based on Size:

Typically, the size of these appliances is measured in cubic feet. Popular sizes range from the compact 0.5 cubic feet models, suitable for small kitchens or dorm rooms, to larger models above 2 cubic feet that can accommodate larger dishes and are perfect for larger households.

Based on Power Consumption:

Microwaves also vary in the amount of power they use, with most models ranging from 700 to 1200 watts. Higher wattage typically results in faster and more efficient cooking.

Based on Functionality:

Countertop microwaves range from basic models that are used for heating and defrosting food, to more advanced models with a host of features like auto-cook menus, sensor cooking, and pre-programmed settings for different types of food.

How Countertop Microwave Ovens Work

The operation of countertop microwave ovens is both simple and intriguing. The core component is the magnetron, a tube in which electrons are affected by the magnetic and electric fields to produce microwaves. Once the microwave oven is switched on, the magnetron generates microwaves that are distributed evenly inside the oven by a stirrer fan. These microwaves are then absorbed by the food.

Due to their frequency, microwaves cause water molecules in the food to vibrate, subsequently producing heat through this friction, which, in turn, cooks or heats the food. The cooking time can vary based on the amount of food, its density, and its water content.

One of the key safety features in microwave ovens is the interlock switches, which automatically shut off the microwave generation if the door is opened. This ensures that users aren’t exposed to the potentially harmful microwaves.

The Science behind Countertop Microwaves

Microwaves are electromagnetic waves with a frequency of approximately 2.45 gigahertz and a wavelength of 12.2 centimeters. These waves are absorbed by water, fats, sugars, and certain other substances, which gives them their cooking properties. Other materials like glass or ceramics and certain plastics are microwave-transparent, meaning they let microwaves pass through them, thereby allowing food to absorb the microwaves.

When food absorbs microwaves, the energy is converted into heat. This heat cooks the food from the inside out, which generally leads to quicker and more uniform cooking as compared to traditional ovens. The fact that microwaves cook food from the inside out can be seen when frozen food is microwaved: the outside layers are often hot while the interior is still cold.

Concerning health aspects related to microwaving food, it has been widely researched and concluded that microwaving does not make food “unhealthy”. Any cooking method can result in a loss of nutrient value, and microwaving is among the methods that retain most nutrients due to the short cooking times.
