What is a Dehydrator: How does it works?

Dehydration, an amazing innovative technique for preserving food, has had a lasting impact on the contemporary food industry.

Many of us have enjoyed dried fruits, granola, chips, or jerkies without fully comprehending the fascinating process behind their transformation from juicy and plump to chewy and convenient.

However, this amazing magical effect is achieved through the use of dehydrators.

To shed light on food dehydrator machine for home use, we are going to present an in-depth article about electric food dehydrator uses and electric food dehydrator function.

What Is A Food Dehydrator?

What Is A Food Dehydrator?An electric food dehydrator, as the name suggests dehydrates the food by extracting the primary extract moisture, contributing to its preservation and extending its shelf life.

This process involves circulating warm air at temperatures ranging between 40°C to 75°C over an extended period.

By removing excess moisture without compromising essential nutrients, the resulting dehydrated food becomes lightweight and more suitable for outdoor activities like hiking.

A food dehydrator machine for home use is often designed with fans, vents, and in some cases even glass doors for convenient monitoring of the drying process.

Food Dehydrator Function

Now that you have learned about what is a food dehydrator machine for home use, here we have a food dehydrator function. Have a look!

1.  Adequate Airflow: The electric food dehydrator function by utilizing a built-in fan to establish controlled, gentle airflow at a low temperature. This critical element facilitates the dehydration process effectively.

2. Proper Placement: For uniform drying outcomes, it is important to properly arrange the food items in a single layer on the electric food dehydrator trays, ensuring they do not come into contact with each other and allowing for consistent airflow throughout.

3. Temperature Regulation: The appropriate temperature for food dehydrator function depends on the specific food and its moisture content:

  • Fruits, which have high water content, benefit from a higher temperature of approximately 135°F to expedite drying without excessive crispiness.
  • Vegetables can be dehydrated at a slightly lower temperature of around 125°F.
  • Delicate Items like herbs require the lowest temperature, usually about 95°F, to prevent over-drying and discoloration.
  • When dehydrating meat, it is essential to prioritize safety by first cooking it to an internal temperature of 165°F to eliminate potentially harmful bacteria. Subsequently, within the range of 130°F-140°F, efficient dehydration can take place in electric food dehydrators while ensuring food safety is maintained.

How To Use Food Dehydrator Machine For Home Use?

Oven Vs Dehydrator

There are notable distinctions between ovens and electric food dehydrator machine for home use.

Electric food dehydrators are specifically engineered for this task and have the capability to achieve lower temperatures, typically ranging from 85 to 160 degrees Fahrenheit, with some models even offering settings as low as 20 degrees Fahrenheit. On the other hand, ovens usually begin at higher temperature ranges of 150 to 200 degrees Fahrenheit which can be excessively hot for delicate drying purposes and can potentially lead to cooking the food, thereby causing a loss in flavor and nutrients.

Electric food Dehydrators are also much more energy-efficient. A 1000W dehydrator uses a lot less energy to operate for 12 hours than a 5000W to 38,000W convection oven does.

Effective dehydration requires precise and constant control of temperature over a long period. The majority of standard ovens have trouble maintaining such control, which results in hot and cold spots, though some high-end ovens do offer this. This is less of a problem in food dehydrators.

How To Choose The Best Food Dehydrator?

There are crucial factors to take into account when shopping for an electric food dehydrator to make an educated decision:

Wattage: Consider the wattage of the food dehydrator machine for home use. Although they consume less energy, lower-wattage models take longer to heat up. Although they may be more expensive to buy and run, higher-wattage units are more potent and heat up more quickly.

Size and Space: Make sure the dehydrator fits in the space you have available. Make sure it fits the space where you want to put it by checking its dimensions.

Capacity: Consider the capacity of the food dehydrator machine for home use. Smaller commercial dehydrators are adequate for drying a few herbs, but larger ones are required for higher-volume operations, such as a jerky business.

Materials: For use in restaurants, commercial dehydrators frequently have sturdy stainless steel construction. Choose models with a less expensive plastic body if you won’t use it frequently or if cost is an issue.

Timers: A basic on/off switch is available on some electric food dehydrators, which is useful when you can keep an eye on the drying process. Select a model with an integrated timer if you value a more hands-off approach. For overnight drying, some units even have automatic shut-off features.

Stackable: Stackable countertop electric food dehydrators are an option if you need more capacity without taking up a lot of floor space. You can buy several stackable units to make the most of vertical space while avoiding busy areas.

Tips For Dehydrating

  • Uniform Slicing: Before dehydrating, slice your food into uniform pieces. Thicker slices dry more quickly.
  • Proper Setup: Arrange the food on the trays in a single layer, leaving about 1/8 inch between each item.
  • Texture Preference: Dehydrate food for less time if you prefer a chewy texture. Adapt to suit your preferences
  • Checking dryness: A dehydrator should be turned off when the food is flexible but dry. Remember that as it cools, it will lose some of its flexibility.
  • Complete Dehydration: Before long-term storage, food must be completely dry. Place dehydrated food in a plastic bag and seal it to test. If moisture droplets appear after a day or two, the item is not completely dry and needs to be dehydrated once more.


In conclusion, electric food dehydrators are essential for preserving food by eliminating moisture and inhibiting the growth of bacteria and mold.
