What Is A Food Dehydrator?

​A food dehydrator contains several stacked trays that can hold different foods. With them, you can dry out vegetables, fruits, seeds, herbs, fish, and meat.

The relatively small appliances use heating elements to gently circulate warm air throughout, to reduce the level of moisture in food.Moisture content in food generally accounts for around 50-90% of its weight.

This moisture gives life, but in this context it creates bacteria. With a lot of the water removed, food becomes safe for long term storage – for several months or even for several years.

To use a food dehydrator, all you have to do is cut the food that you want to dry, and stack the shelves with it. You will get a feel for how thick to cut each item of food in order to get an even dehydration throughout. Once prepared, you simply place the trays in the dehydrator, turn it on, and await results

Types Of Food Dehydrator​

​There are basically two types of food dehydrator; the stacked version, and the box and shelf.

Stacked food dehydrators

Stacked food dehydrators include several racks, with each containing a tray to hold food. The stacks are placed one on top of the other, and can be sealed to keep in the heat. They usually contain no outer shelf, and the fan is located at the bottom with a vertical heat circulation.

Stacked dehydrators use less energy, and the size varies according to the volume of food you are dehydrating. The main drawback is that food which sits closer to the heating element (i.e. on the bottom shelf), tends to dry faster. You will therefore have to shuffle the racks around regularly to get an even effect.

Box & Shelf food dehydrators

These types of food dehydrator contain an outer shell, with inner shelves and trays. They function more like electric ovens, and the fan is located at the back of the box to blow hot air through the food on the shelves.

The box and shelf units offer better insulation, and a more even dehydrating process throughout all shelves. The main drawback is that they tend to be bulkier and more expensive.

Benefits Of A Food Dehydrator

Food dehydrators offer many benefits to your everyday life. They give you the capability to dehydrate food for a number of purposes, without resorting to using your oven – which can overheat foods, trap in moisture, and generally are not as efficient. The main benefits are:

  • Food dehydrators dry out food using much less energy and space than an oven
  • You can preserve foods without the need for additives and preservatives
  • Gardeners can easily store excess foods that they have grown
  • Food can be safely stored, and enjoyed many months later
  • The process is much easier than canning food for storage
  • Hikers, campers, and outdoor enthusiasts can enjoy healthy and nutritious snacks, without carrying lots of weight and using lots of space
  • You can eat out of season foods – for example, enjoy summer fruits in the winter. Great for kids, and for anyone who wants to eat healthily
  • Opens up cooking options... make your own beef jerky and dried meat snacks, or use your dried seasonal vegetables to make a nice stew

Factors To Consider When Buying​

​The world of food dehydrators is not so complex, and there isn't too much difference between many of the high quality models that we discuss here.

However, as with any purchase there are a number of factors to consider when making your choice. You want to find the right dehydrator for you, and one that suits your lifestyle and your needs. Food dehydrators are available in a range of different sizes and shapes, and some have special features that can be attractive.

​Size & Capacity

​One importance decision, is to decide on the size and capacity of the food dehydrator that you will need. Some dehydrators come with a limited number of trays, as little as five. This might be perfect if you only use them to dry a small amount of food, but most people will want to broaden their capabilities with a 12-20 tray model.

Stackable dehydrators offer scalability, and can be reduced to the size of a large lunchbox if you are only using a few racks. You can add more and scale up vertically, without taking up more space in your kitchen. A box and shelf model takes up whatever space it takes up, and they are usually bulkier.

Your choice may often depend on the amount of space you want your dehydrator to take up in your kitchen, but this must also be balanced by the amount of food you will want to dry on a regular basis.


The power of your dehydrator effects the temperature and drying speed of your device. You can find units with as little power as 125 watts, and as high as 1000 watts. More powerful dehydrators tend to be more effective and desirable, but also more expensive. The size often correlates to the power, with larger units requiring more power to be effective. Ideally, you should aim to buy one with over 500 watts of power.

Heat Distribution

There are two main ways in which food dehydrators distribute heat. Both use heating elements, but the placement of these can vary across units.

Stacked dehydrators tend to use vertical heat from fans that are usually placed at the bottom of the unit. This can give a quicker drying time, but an uneven heat distribution. If the fan is on the bottom, food can drip and this can cause other foods to adopt unusual flavors. You don't want your pears tasting like onions!

Box and shelf models are more likely to have fans located on the sides, which give a horizontal heat distribution. This prevents dripping and the blending of flavors, and also gives a more even distribution that no shelf shifting, though the food generally takes longer to dry out.

Extra Features

There are a few extra features available that can really seal the deal when it comes to your preferred food dehydrator:

  • Timer – While not essential, the timer function makes dehydration pretty much effortless. If you leave food drying for too long, it can become over-dried and even burnt. The timer negates this risk. It also allows you to dry food overnight or while you are out of the house, and to continue your busy day.
  • Thermostat – A built-in thermostat gives you more control over your cooking process, allowing you to adjust the temperature depending on the food you are drying. For example, meat can be dried much quicker. This also means you can decide how dry and crisp you want your dehydrated foods.
  • Interior Lighting – A simple but useful feature is interior lighting. It allows you to see how dry your food is, without removing the trays and loosing heat.


As with all household appliance purchases, the other factors will be considered alongside your budget. Is it worth spending those extra pennies to get a larger dehydrator? Are you willing to fork out a little more cash for those extra features?

Stacked dehydrators come much cheaper than box and shelf types. They tend to retail for below $100, and come as low as less than $50. The box and shelf models usually cost somewhere in the range of $200-350, and are a much more serious purchase, but the extra space, reliable heating distribution, and features tend to make them stand out as a valuable choice.

Excalibur 3926TB

Excalibur 3926TB Food Dehydrator

The Excalibur is widely regarded as the best food dehydrator on the market. The quality of the unit is unmatched, and it is full of features that make it a complete and wholesome choice for anyone serious about drying their veg. It has a huge 15 sq feet of drying space set over 9 large trays, expandable to 15, making it suitable for large families and avid gardeners.

The Excalibur 3926TB has a modest motor that runs at 600 watts, but the fanning system itself is where it excels. It combines 'Parallex Horizontal Airflow' with 'Hyperwave Fluctuation Technology'. In plain language, this means that cold air is sucked in, heated up, and then can escape the unit with the moisture.

The Excalibur is extremely effective, and usually takes around 3 hours to dry fruit and veg, which it does really evenly using a 7” rear-mounted fan. In terms of features, the model comes with polyscreen trays, which prevent food from sticking. It also has a thermostat for temperature control, and a 26 hour timer for absolute convenience.

The main drawback of the Excalibur 3926TB is that it is bulky, weighing 22 pounds and occupying quite a bit of kitchen space. The large trays do not fit in a conventional dishwasher, and must be washed by hand. It is also not the cheapest model in the list, at over $250, but then you get what you pay for. The Excalibur really is a quality food dehydrator!

Nesco Snackmaster Pro FD-75A

Nesco Snackmaster Pro FD-75A

A bestseller on Amazon, the Nesco Snackmaster has a rating of 4.5 with a massive 2433 reviews. There is good reason for its popularity. The first is the price. The Snackmaster retails for less than $60, making it a bargain for anyone who wants a highly effective dehydrator. It may not have all of the features of a premium model, but it does a great job of drying fruits and veg in under 12 hours.

The Snackmaster utilizes a patented Converga-flow system, which creates horizontal and vertical airflow with a top-mounted fan. It has 600 watts of power, enough to reach temperatures of 95-160 Fahrenheit, and an adjustable thermostat for more control.

This model is compact, and won't take up much counter space. It comes with 5 trays, and includes two screens for sticky foods and two fruit roll sheets. If you need to expand it, you can purchase extra trays, and up to 12 can be used at a time. The Vita-Save exterior casing helps to retain nutrients and vitamins when drying.

It may seem a little bit gimmicky, but the Snackmaster also comes with a useful 52 page recipe book to help you make the most of food dehydration. It also comes with jerky seasoning!

The main drawbacks of the Snackmaster food dehydrator, is that it lacks an on/off switch. Users have to resort to plugging and unplugging the machine. The trays are also not dishwasher friendly. However, for the price it is a really great all-round dehydrator that is suitable for most users.

Presto 06300 Dehydro Electric

 Presto 06300 Dehydro Electric

The Presto has 600 watts of power for its bottom-mounted fan, which gives an effective vertical airflow for quick dehydration, especially for the bottom shelf items. This is also its biggest drawback; the top shelves may dry slower, and trays need to be rotated to achieve an even dehydration. The top shelf is transparent, so you can easily check the progress of your veggies.

The Presto also lacks a timer and adjustable thermostat, features that are most often reserved for higher-end models. This can be problematic for dehydration of meats and jerky, which require higher temperatures. The temperature range of the Presto Dehydro is 135-145 Fahrenheit, which is plenty, but the lack of control may put some people off the purchase.

Despite this, the Presto excels as a basic model, and will suffice for most home users. It is compact, it works well, and it costs less than $40. It also comes with clear instructions and a handy recipe book. Anyone who wants to enter the world of dehydrated food, will find the Presto a great starter dehydrator.

Nesco Gardenmaster FD-1040

 Nesco Gardenmaster FD-1040

We could choose many Nesco brand dehydrators for our top rated products, but the Gardenmaster makes our favorites list as an excellent mid-ranged option that is refined, full of features, and reasonably priced at less than $100.

The Gardenmaster boasts 1000 watts of power, which is useful if you want to expand the number of trays while still obtaining decent dehydration times of just 4-6 hours for most fruits and veggies. You get four trays as standard, but you can use up to 20 trays at a time, and we recommend buying at least a few extra to expand the capacity.

For effective heating and air circulation, the Gardenmaster utilizes the patented Coverga-flow air flow, which uses a top-mounted fan to push air vertically, and then horizontally across each tray. You don't need to sway the trays around at all, as the heat distribution is very even. The 2400RPM motor further speeds up the process.

In terms of features, the Presco FD-1040 Gardenmaster has a programmable digital timer, so you can just set the food to dehydrate, and leave it be while you sleep or get on with your day. The adjustable thermostat gives temperature control from 90-160 Fahrenheit, while the Vita-save exterior blocks light and preserves nutrients in the food.

A few customers have complained about the noise that the model makes during dehydration, but this is a relatively small issue when you consider the power of the machine, as well as the value. The Gardenmaster is a great choice for those who want a powerful, effective, and feature full dehydrator, without paying for a top of the range model.

STX International Dehydra STX-DEH-1200W-XLS

 STX International Dehydra Food Dehydrator

The STX is not as popular as the less expensive models in this list, but that is because most people are looking for a beginner level model. For the serious food enthusiast or gardener, and those who want to dehydrate food regularly, the STX DEH is an excellent choice, and a sturdy and reliable option.

Made from 304 stainless steel, rather than the plastic that most models make, the STX will last for a long time to come, and has a 3 year warranty to prove it. It has 1200 watt of power, and a 95-155 Fahrenheit horizontal airflow, for effective and well distributed heat flow via a rear-mounted fan. It has 10 large metal trays, offering a very decent capacity.

In terms of features, the STX DEH offers a 12 hour shut-off timer, and adjustable thermostat. It doesn't offer anything sci-fi, but the price is reflective of the quantity of food it can dehydrate, as well as the overall quality and durability of the dehydrator.

We can highly recommend the STX to anyone who is looking for a high-grade model, and who is willing to pay the price.​

Final Considerations

The final decision is all yours to make. With this guide, we have given you several reliable options in a number of different price ranges, as well as introducing you to the main factors that you should consider before making your purchase.

The food dehydrator that you choose should reflect your needs. If you are just starting out, or you just want to dehydrate a few snacks every now and then, the Nesco and Presco models are perfect and inexpensive.

Anyone who is dehydrating a lot of food, or using the product regularly, should consider investing in the STX or Excalibur models, which offer a greater capacity, durability, and all the features you need.
