It sounds like dehydrators and air fryers are both convection ovens, though at quite different heat and velocity settings.
I found one on amazon which appears to do both: the GOLUX Multi-Use Smart Convection Countertop Ovens with 5 Drying Trays, Digital Temperature Controls and Timer, with Food Dehydrator Function. It has only one review and I’ve never heard of the company.
I don’t have enough room for both. Is this a viable solution?

When drying nuts in the air fryer – is the heat at a low enough setting (under 118?) so that the nuts will still be considered “raw” when done?

You article has several flaws that could be confusing and misleading your readers. I’m only going to focus on two. A food dehydrator and an Air Fryers are both convection based systems that use the circulation of heated dry air to cook and/or dehydrate foods. The only different between the two is the Max Temp of each unit and the speed of airflow. Air fryers can be used to dehydrate food just as well and sometimes even better than a dehydrator because they allow for a higher temperature. The higher temperature along with the super fast air speed actually shorten the dehydration time. Faster Airflow equals faster dryer and higher heat also equals faster drying to a point. Anything being air heated above 210 degrees is actually going to be cooked instead of dehydrated. The other issue i thought important to address is that you state that anything dehydrated in an air fryer has to be eaten soon or it will spoil. That is actually incorrect. If properly done food that has been dehydrated in an air fryer is no different than foods dehydrated in a dehydrator. Dehydrated is dehydrated not matter what machine you use to do it.

Don’t mean to offend but having factual information is important when people look to shell out a few hundred dollars on a kitchen appliance!

    I read your information and was glad to have my questions answered on the dehydrating of food. I am hoping to use it to make healthy dehydrated vegetable chips. I was worried that storage might be a problem. I plan on storing the dehydrated chips in glass mason jars and adding oxygen absorption packets to hopefully enhance the storage time of the chips. Ty for the time you took to forward this information. It is greatly appreciated. I will be receiving my Power Airfryer this coming weekend and plan on making kale chips from my garden?
