Are Dehydrators Safe To Leave On Overnight or Unattended?


It’s no secret that dehydrating food takes a long time. In most cases anything up to 24 hours.

Although we’ve determined that this is a great way to save money and minimise food waste it can be a concern as to safety when looking at leaving the dehydrator on overnight or unattended while you go to work etc.

However, provided the right safety precautions are taken an electrical food dehydrator is relatively safe to leave on overnight and unattended.

In this post, I’ll be discussing the different safety precautions and other things you should consider when deciding if leaving a dehydrator on overnight or unattended is the right choice for you.

Are Dehydrators A Fire Hazard?

While any electrical appliance is a fire hazard to some degree dehydrator are no more dangerous than a fridge, freezer or computer etc.

The fire hazard is significantly reduced as a result of the low temperatures that dehydrators run at when compared to other cooking appliances such as a toaster oven or kettle.

Prior to using the dehydrator, you should check for damage to the plug or the cord and as always to minimise and protect yourself from or during a fire you should ensure that you have a working smoke alarm which is tested regularly.

You should also check the safety recalls for your make and model of dehydrator every six months or so. In some cases, appliances can be recalled due to a fault which has been reported multiple times and therefore made the appliance unsafe for use by all who own it.

Can You Leave Dehydrators On Overnight?

Dehydrators are designed to be left on for up to 24 hours. After all, it’s this amount of time that’s often required to fully dehydrate some foods.

An while there are some risks to leaving any electrical appliance on overnight they are minimal provided that you check the safety recalls of your appliance, check your appliance to ensure it is not damaged and ensure that your smoke alarm is fully working.

Be sure to leave your dehydrator on a fixed surface and away from anything which could catch fire as a result of heat such as towels and water.

Can You Leave Dehydrators Unattended?

Similar measures should also be implemented when you look to leave your dehydrator unattended for an extended period of time. Again given the fact dehydrating food takes up to 24 hours this is unavoidable in many cases.

While electric food dehydrators pose no more of a risk than other similar appliances in the household it’s always important to ensure they are used in safe conditions.

This includes using them on a fixed surface and away from anything which could catch fire such as towels and water. As well as regularly checking that the appliance is free from safety recalls.
