The Best Food Dehydrators – Unbiased Reviews

Dehydrating food is cost-effective effective and rewarding. Using a dehydrator prepares foods for snacking or storage while taking minimal effort. Cooking, canning or freezing preserves food. But, the process often depletes vital nutrients. On the other hand, by dehydrating food sufficiently, the nutritional value remains. Dried fruits and vegetables provide an abundance of fiber along with vitamins A and C. Dehydrated produce is also a good source of a variety of vital minerals including magnesium, potassium and selenium.

Drying foods give meat, produce and herbs a longer shelf life. Keeping food refrigerated or at room temperature naturally encourages deterioration and molding over time. But, by greatly reducing the moisture content, packaging and storing the end product in a cool, dark place, the food lasts for up to 12 months.

Many people enjoy eating jerky or dried fruits. Dried herbs are commonly used in meal preparation. The cost of the same items made in the home is a fraction of the sale price. Thus, dehydrating saves money in the long run. Garden vegetables that are not immediately consumed need not go to waste when the home has a dehydrator. Fresh fruits are easily made into leather or roll-ups, which are a healthy snack alternative. Fruits can also be sliced and used to make trail mix. Buying produce in bulk is also often cost-effective. By having a dehydrator, the purchase is sure to last long enough to be enjoyed.

Dehydrated foods are also easier to store, as they require less space. The preserved products are additionally portable. Take fruits, vegetables, meats and herbs along for meals at work, on camping trips, hikes or any other activity away from home. Using the foods in meal preparation merely entails rehydrating the foods as needed.

How Dehydrators Work

Food dehydrators available for home use are relatively small appliances that are FDA-approved for drying all types of foods. The devices have some type of mechanism that generates heat, which is circulated through the unit to extract the moisture from the food contents. Once the food is sufficiently dried, bacteria and mold cannot grow. Thus, the foods last longer lengths of time without spoiling. The dehydrated end product is then packaged and stored or consumed as desired.

Types of Food Dehydrators

There are a variety of food dehydrators available for home use. They differ in size and features. But, basically, the devices fall into one of two categories. Some dehydrators have the drying fan units integrated into the base or top of the appliance. Perforated trays are then stacked on top or below the mechanism. The other version entails a self-enclosed box-like compartment into which the perforated trays slide in and out. The heating unit and fan are typically located in the rear of the devices. There are additionally dehydrators that use convection to create heat and do not require a fan.

There are advantages to each category of dehydrators. Stacked tray versions circulate the warm air along the unit’s outer walls and through the central channel. The process continues until the food is dried. The devices also enable the user to adjust the number of trays needed to dry particular batches of food. Stacking appliances are also the least expensive. But, despite the ability to stack trays extremely high, the air may circulate unevenly. So, the food closest to the heating element dries faster, which necessitates rotating the trays.

In shelf dehydrators, the air flows horizontally from the back of the appliance to the front. The units are often preferred, as they dry foods more evenly. The lack of a central channel also enables users to place food slices on the entire tray. The trays do not need rotating. Having the ability to slide the trays makes it easier to check the dehydration process. But, the cabinets limit the number of trays that may be processed at one time.

Some units use convection to dry food. The heat is created by an internal element, which is typically integrated into the base of the device. Convection dehydration requires less electricity while enabling the appliance to function silently. However, convection heat takes approximately double the time to dry bulky or moisture-rich foods. Plus, the longer it takes to dry the food, the more the unit reduces the flavor of the end product. But, convection dehydrators are preferred by some for the fact that they do not have a fan that may draw airborne contaminants into the device. Ensuring the space in which any type of dehydrator is used remains clean eliminates the problem.

Home-use dehydrators come in a myriad of sizes. Some easily sit atop a counter and may be kept there when not in use. Other devices require more space due to their overall larger size. All are powered by simply plugging the unit into a common household outlet. The devices typically have controls that enable the user to set the device to the desired temperature. Certain models turn themselves off once the dehydrating process completes. Others must be manually turned off.

Features to Look for When Choosing a Food Dehydrator

  • Even air flow – Quality dehydrators contain a heating element and a fan. The combination ensures that the air travels evenly across the entire surface of each tray. Dehydrators use 300 to 1,000 watts of power. They may have fans measuring four to seven inches in diameter. A few models have two fans. But, they make more noise during operation. Otherwise, expect the appliance to sound similar to a typical household cooling fan.
  • Adjustable thermostats – An adjustable thermostat is a feature that the dehydrator should possess. The thermostats enable users to set the temperature between 95 and 155 degrees Fahrenheit. Different types of foods require specific temperatures to dry efficiently. Thus, a model that enables the adjustment makes the unit more versatile.

Food Dehydrator Usage

Regardless of what type of food dehydrator someone selects, there are a few things to consider to enhance user experience.

  • Simple washing – Upon receiving the package. Unpack the device. Wash the trays in warm, soapy water. Wipe down the interior of the cabinet or the fan base with a soft, moist cloth. Insert the dried trays and run the dehydrator for up to 30 minutes while empty. Although the units and components are made with food-grade, BPA-free materials, they may initially emit an odor during the first operation. Operating the device empty reduces the problem in order to not affect foods.
  • Clean the area – Before drying foods, make sure that the food prep area is clean and possibly disinfected to prevent contamination by surface or airborne organisms.
  • Consider environmental humidity – Properly drying foods requires that they are processed to remove up to 95 percent of their moisture content to prevent bacterial or mold growth. The dehydrating process may take longer or become inefficient if operating the appliance in an area where air conditioning units are also working. Similarly, do not use the dehydrator in an area where an open vent or window is emitting a breeze.
  • Be patient – It might be tempting to dehydrate foods at a higher temperature than recommended to shorten the processing time. However, a warmer setting processes the foods from the outside inward. Thus, the external surfaces may feel dry but moisture remains hidden inside, which promotes microbial growth and spoilage.
  • Food preparation – Use a mandolin or a similar device to ensure that the food items are close to being equal in thickness. Otherwise thinner slices process more quickly, which leaves thicker items partially dried. Certain fruits and vegetables may require blanching or steaming for five to 10 minutes before processing. The action merely helps retain the color and flavor of the foods. Low-acid foods may require spritzing with lemon or lime juice before processing. However, make sure the surfaces are dry before dehydration by patting with a paper towel. Foods rich in fat do not dehydrate well. Dehydrating alters the flavor and commonly renders the items rancid.
  • Boost dehydrator efficiency – Not unlike using an oven, consider warming up the dehydrator briefly before adding the food trays.
  • Food storage – Properly processed foods may be stored in tightly closed canning jars or plastic freezer containers and kept in a cool, dark location or the freezer. But, using a vacuum sealing appliance greatly reduces the amount of air that comes in contact with processed foods, which lengthens shelf life.
