Can You Stop and Restart a Dehydrator?

Whether you’re munching down on some dried fruits or looking forward to that beef jerky you’ve got waiting back home, there’s no denying the brilliance of a dehydrator. However, using one can be confusing sometimes. For instance, can you stop the dehydrator and restart it later?

You can stop and restart a dehydrator much later as long as you keep tabs on how much time is left to complete the drying process for the specific food item in it. An alternative to stopping and restarting a dehydrator out of necessity is to install an outlet timer.

In this article, I’ll cover all you need to know about stopping and restarting a dehydrator. Does it make sense, and will it affect your food? Read on to find out!

What Is a Dehydrator?

A dehydrator is an appliance that dries materials at low temperatures over a long time.

They’re mostly used to dry foods, but it’s not uncommon to find dehydrators in certain work environments outside the kitchen.

How Does a Dehydrator Work?

A dehydrator works by circulating air at a very low temperature. The food materials to be dried have to be spread out inside the appliance to ensure completely even drying. Most manufacturers have a recommended drying temperature for different types of food materials.  

The water content is the major determinant of the temperature. Water-dense foods such as fruits can benefit from drying under higher temperatures such as 135°F (57°C), while you can dehydrate vegetables at around 125°F (52°C). Delicate foods such as certain herbs have to be dehydrated at lower temperatures around 95°F (35°C) to avoid discoloration and excessive dehydration.

You typically dehydrate meats at 130°F to 140°F (54°C to 60°C), but only after cooking to achieve an internal temperature of 165°F (74°C) first.

What Are the Benefits of Dehydration?

The benefits of dehydration include giving any food a stronger flavor due to the lack of moisture. Herbs will feel more pungent, while fruits will be sweeter. It also makes storing the foods over prolonged periods easier overall. 

In addition to the increased shelf-life and better flavor, you don’t have to worry about preservatives, sugar, oil, or other unwanted ingredients. This makes foods dried this way healthier than those bought off supermarket shelves.

Additionally, some cooking methods ruin the nutritional content of certain food types. Dehydrating ensures better nutrient retention.

What Are Other Uses of a Dehydrator?

Other uses of a dehydrator apart from drying fresh fruits and vegetables include:

  • Make dehydrated molds for painting
  • Make stale foods like crackers and cookies crisp again
  • Make dog treats
  • Ferment  yogurt
  • Make dry homemade pasta

Why Stop and Restart a Dehydrator?

As we mentioned above, you need to put the food item in your dehydrator for a considerable amount of time to dehydrate fully. Sometimes, this means waiting 8-12 hours. 

You might stop and restart a dehydrator later if you suddenly have to go out or need to retire to bed and don’t want to run the risk of having the food dry too much.

Is it a Good Idea To Stop and Restart a Dehydrator?

It can be a good idea to stop and restart a dehydrator in many cases – as long as you remember to complete the drying process. Half-dried food items can go bad quickly if left for long in the dehydrator when it’s turned off.

However, some foods may also become brittle if you stop and restart the dehydrator when you’re already well into the process.

If you’re unsure of how long you’ll be away, take out the food items and put them in the fridge until you return. This is most important when you’re dealing with sensitive foods like meat, yogurt, etc. 

However, if you’re sure of getting back just in time, it may be best to leave the dehydrator working. Some people prefer to turn off the appliance after taking note of how much time is left in the process and turn it back on to complete the remaining dry time recommended for the food item.

To avoid any problems after stopping and restarting a dehydrator, you need to know the perfect dry time for the food item and how long it’ll take your dehydrator to cool down and reach the top temperature again. If you stop and restart with these in mind, your food should turn out fine.

Alternatives to Stopping and Restarting a Dehydrator

If you don’t want to stop and restart your dehydrator at all, there are a couple of things you can do:

Buy an Outlet Timer

Outlet timers are cheap products that can allow you to decide how long you want any appliance connected to the outlet to stay on.
