Read on for an honest opinion about what’s worth it and what’s not.

I’ve used a 9 tray Excalibur dehydrator since 2011 to preserve fruits and vegetables and for making meals to take on trips. I’ve led numerous dehydrating workshops and have spoken to hundreds of people about their dehydrating experience. This article is based on my personal experience and what I’ve heard from others I trust in the kitchen.

2 Tips to get started

  1. Get the best equipment you can afford. While the initial investment is high, you’ll be less frustrated and it’ll last you for decades. Remember, good equipment has great resale value – should you decide you don’t want to continue dehydrating.
  2. Choose equipment that fits your personal needs and goals. Are you interested in making a few snacks, preparing food for trips or outdoor activities, preserving all your garden produce, making jerky or stocking an emergency food pantry? The more intense you want to get, the more research you should do into the size, quality and cost of equipment.

Equipment Needed for Dehydrating

Electric Dehydrator

When it comes to dehydrators – you get what you pay for! Small, cheap dehydrators are small and cheap. They dry food, but the process is frustrating with hot and cold spots, parts that break, machines that are difficult to clean and cumbersome to use. You’re better off borrowing or buying a good quality, used dehydrator than getting a cheap model.

Consider your choices carefully and be sure to read reviews and get opinions from others.

Two Common types of Electric Dehydrators

1) Round & Stackable with Vertical Air Flow – Round dehydrators with a core channel in the center to allow heated air to flow through vertically. The donut shaped trays are typically removable and stackable for small or large batches. For best drying these trays must be rotated throughout the process. These units are the most affordable and vary greatly in quality. Look for a unit where the fan and/or heater are on the top, rather than the bottom so food droplets don’t land on the heating element (hard to clean and potentially destructive).

I’ve heard good things about this 5 tray Nesco 600-Watt Food Dehydrator.

2) Square Trays with Horizontal Air Flow– Square dehydrators with trays that can slide in and out for easy checking. Airflow is pushed from the back of the unit via one or two fans allowing for more even air flow across all food. These units come in set sizes and offer various options. For large volumes with little hands-on work these larger, higher priced units are worth considering.

This is the 9 tray Excalibur 3900 that I love and have been using since 2011.

For either type, check for the following:

  • Temperature control – adjustable thermostat so you can control the temperature ranging from 95 -165ºF or 35-73°C
  • Watts – power for heating and air flow, look for at least 500 watts or more for reasonable drying time
  • A Fan – creates air flow for better, quicker more consistent results but they also cause more noise
  • Sturdy Construction – for a long lasting, easy to clean machine, look for sturdy, double wall construction of metal or high-grade plastic
  • Convenient Trays – look for sturdy trays – either stainless steel or high-grade plastic with removable/flexible plastic mesh to make it easier to remove food and clean. Rigid plastic trays with built in mesh are harder to clean and I’ve heard that they can crack or warp.
  • Four Tray Minimum – get a unit with at least four trays – you’ll outgrow anything smaller very quickly
Options I wouldn’t Pay Extra For:
  • Glass Door: Watching food dry is on no-ones must see list! There’s no way you can tell if food is dry or not through a glass door. It’s cute, but not necessary.
  • Timer: A timer is a nice option, but I wouldn’t pay extra for it. Exact timing varies every time you dehydrate something, so you can’t rely on a set time. That said, if you can’t check your dehydrator at the approximate time, it’s nice to have your dehydrator stop the drying process until you can check it – just don’t forget about it!

PRO TIP: If you ever need an auto-shut off for your dehydrator, plug it into a timer at the electrical outlet – like the one for Christmas tree lights.

If a timer is included in your dehydrator great, but I wouldn’t pay extra for one. On the rare occasion I need a timer, I use our Christmas light timer at the outlet.


Trays come with built in mesh grates or separate mesh sheets. These are ideal for pieces of food the size of a chickpea or larger. For smaller food, fruit leather, pastes, soups or other liquid food you need liners. Most dehydrator manufacturers will sell Paraflexx or silicone based sheets to fit their dehydrators. Buy them or some sort of alternative – you will definitely need them.

Paraflexx sheets for small or liquid foods. Expensive, but a good quality, reusable liner that allows air to penetrate is necessary.

They’re not cheap, but they are necessary and getting good ones that will last for 10 years or more is well worth it. When I first bought my 9 tray dehydrator, I only bought 5 liners. It wasn’t often that I needed liners for all 9 trays at a time so it was a good start. When I needed more, I used parchment paper. A couple of years ago, I bought some of these reusable silicone liners at the grocery store. I cut them to fit my trays and they work quite well.

This silicone roll can be cut to size and make good liners for dehydrating.

PRO TIP – NEVER use Wax Paper in the dehydrator, food will stick and never come off! Foil is also not great. In a pinch you can use plastic wrap, but you’ll need to flip the food on the wrap and extend drying time since air cannot pass through foil or plastic wrap.

Cutting & Slicing Tools

Consistent sized food is very important for even, safe drying.

A good knife and cutting board will definitely do the trick. But when filling a whole dehydrator, sometimes a tool to keep your slices consistent is helpful. When I’m filling my dehydrator I pull out my mandoline, food processor or apple peeling device – whatever will make the job easier.

Use a mandoline for even slicing.
I love my apple peeler and slicer, it makes perfect apple rings. I dry the peel and broken pieces for tea blends, oatmeal and trail mix.

Immersion Blender/Food Processor

A blender or powerful food processor will help with preparing food both before dehydrating (e.g. making smooth fruit leather or soup puree) and after dehydrating (e.g. making garlic powder).

I love my immersion blender for soups and fruit leather puree.

Spreading Tool 

A smooth even layer of spreadables will dry vegetable bark, leftovers and fruit leathers better. A large knife or silicone scraper will work, but an off-set spatula makes it even easier.

If you want to make powders or food that’s quick to re-hydrate you need something that will turn your dried food into a powder. A chopper, food processor, mortar and pestle, spice or coffee grinder will work.

I use an old coffee grinder I bought at a second hand shop to make powders or instant meals for the trail. I find a coffee grinder creates a finer powder than my food processor.

Airtight Containers/Bags

Once you’ve dehydrated your food, you’ll need to store it properly. You need air tight containers or bags.

I use recycled glass jars to store my dehydrated food. When I take dried food on trips, I usually use ziploc freezer bags (thicker than regular snack bags), reusable silicone bags, plastic containers or vacuum sealed bags.

For long term storage (more than a year), you can also use food grade mylar (metalic) bags that will lock out oxygen and light. Look for bags without a window panel to keep light out.  I have never used them so am hesitant to recommend a particular kind, just research them carefully to ensure you get a good quality bag.

I use miscellaneous sizes and shapes of jars to store my dehydrated food. Don’t just use one size for everything, you don’t want too much airspace in your jars. Read How to Store Dehydrated Food.

Vacuum Sealer

Vacuum sealing will extend shelf life even further but is not necessary for food that will be used within six months to a year. Read more about How to Properly Store Dehydrated Food.

It is ideal if you are taking dried food into a humid environment or if you are storing food beyond a year. Look for a vacuum sealer with an attachement that can do bags and jars.

I use a vacuum sealer when taking food on treks where moisture is a concern.

Oxygen Absorbers

Oxygen absorbers are useful if you’re planning to keep dehydrated food for more than one year. I have never used them because I circulate through my food fairly quickly.

If storing food for more than 1 year, consider using oxygen absorbers.

Marker or Grease Pencil

Do not underestimate the need to label your food. You likely won’t have trouble identifying a dried pea – but is that white powder dried cannellini beans, mashed potatoes, mushrooms or cauliflower soup? You also want to include the packaging date so you know how long your food has been on the shelf. And if you’re hitting the trail, you’ll want rehydrating and cooking instructions.

A sharpie works great on plastic bags. For glass jars or lids that I want to reuse, I like using grease pencils. If I’m feeling really crafty, I use chalkboard paint to cover old jar lids, then I use a white grease pencil to write with. An eraser will take off the writing and leave the paint so I can wash and reuse the lid for something else.
