What Does A Food Dehydrator Do And How Does It Work?

Food Dehydrator has natural moisture inside it. Everything from berries and fruits to meat and fish has moisture that will shorten the item’s shelf life. Moisture is great, but it will also cause food to spoil faster. If you’ve recently purchased a bushel of apples, for example, you can cut some of the apples up and dehydrate them so that they last longer.

What is a Food Dehydrator?

From the name of it, you’ve already figured out that this is a device that dehydrates certain foods. This is done through an appliance where the food is placed, and the process begins. Depending on the amount of moisture in the food, it can take hours for dehydration to occur.

You may even notice that your food has:

  • Become irregularly shaped due to lack of moisture.
  • Lost weight and has become lighter.
  • Changed color and looks a lot different than when it was hydrated.

For centuries, this was a process that occurred outdoors. People would gather the food they want to dehydrate and place the item, sliced or whole, in the sun. As you can imagine, food would be eaten by insects and animals on many occasions.

How Food Dehydrators Work

So how does a dehydrator function? An electrical machine that extracts the moisture content of everything inside is a dehydrator. It is made up of trays, heating parts, vents, and a circulating fan. Within the unit, the heating device of the dehydrator increases the temperature, the fan circulates the heat uniformly and removes the moisture, while the trays hold the food you want to dehydrate.

Many specifics, of course, go into the practical use of a dehydrator. “You can’t just cut the food, throw it in the machine, close the door, and say, “Work! “It can also intimidate certain information.

There is a temperature scale for dehydrators to use, and you need to learn the temperatures that are most suitable for each food. There are timetables for how to dehydrate your particular food properly. Then on the market, there are many dehydration machines out there, so you need to know what to look for and what to stop while on the prowl.

Fortunately, our curiosity has led us to great discoveries, and we are pleased to share them with you in the hope of guiding you in the right direction! Continue reading to find out.

Dehydration occurs inside of the appliance. But there are two different methods that are often utilized.

Solar Dehydration

A method inspired by traditional dehydration techniques. These devices have racks and small openings which allow for better overall protection of the food. The biggest issue with the solar method is that there is no consistency during the dehydration process.

Some parts of the food may have more water than others.

The main culprit is the direction of the sun. Since there is no way to ensure that the sun remains in the same spot evenly heating the food to dehydrate it, you’ll have foods that are partially dehydrated often.

Modern Methods

Modern methods use electricity to power an appliance that resembles a small crockpot. Dehydrators will include several trays where food can be stored and dried at the same time. The separation ensures that none of the flavors mix during the process.

Removable and stackable trays, as well as shelving, may be present.

Circular drying racks may even rotate to allow for proper dehydration at all times. Using a temperature setting, you’ll find most models allow you to dehydrate at a temperature range of 95 – 145 degrees.

The process can still take hours, but the heating element allows for even dehydration that is very hard to achieve in the sun.
