A dehydrator preserves foods, such as fruits and vegetables, by removing their moisture and preventing the growth of harmful microbes. Dehydrating food also decreases its size, allowing you to easily store large quantities of food in a single bag or container.

Buyer’s Guide

When buying a dehydrator, it’s important to know how each model’s unique features and specifications affect its performance. Here are five factors to consider before making a purchase.


Dehydrators typically have between five and 10 trays, though some models can expand to hold up to 12. The size of each tray is closely related to the dimensions of the dehydrator—the larger the dimensions of the dehydrator, the larger the trays.


The amount of power a dehydrator has is measured in watts. Most dehydrators deliver between 400 and 600 watts of power. If you want to dry a large quantity of food at a high temperature, look for a model with a high wattage.

Safety Features

Some common safety features in dehydrators include overheating protection and automatic shut-off. Overheat protection turns the appliance off if it reaches an unsafe temperature. Automatic shut-off works with a digital or analog timer to turn off the dehydrator after a preset time.


Most dehydrators operate using an adjustable thermostat, though some models use preset temperatures. Owning a dehydrator with several temperature settings lets you dry various types of food. Most dehydrators dry in temperatures between 95 and 165 degrees Fahrenheit.

Heating Technique

Dehydrators typically use a horizontal or vertical heating method. A horizontal heating method pushes air from the back of the machine to the front for more uniform heating. However, these models are usually more expensive than their vertical-heating counterparts.

Vertical-heating dehydrators push heat from the top of the machine to the bottom, or vice versa. Although these dehydrators are more affordable, they’re usually smaller and more inconsistent.

Frequently Asked Questions

What can you use a dehydrator for?

Dehydrators allow you to prepare a variety of foods, including:

  • Beef jerky
  • Dog treats
  • Potpourri
  • Dried fruit

Are dehydrated foods healthy?

Since dehydrated foods are usually free from added sugars and preservatives, they are a great source of vitamins and minerals. However, the dehydration process can destroy some of the food’s nutritional value.

Is it safe to dehydrate raw meat?

No. While dehydration is good for removing the harmful bacteria that cause food to spoil, the heat isn’t intense enough to kill those that thrive in raw meat. Be sure to cook any meat to its proper internal temperature using a meat thermometer before drying it.
