All dehydrators are not created equal. When I first began researching dehydrators, I had no idea what to look for. It never dawned on me that they may or may not have temperature gauges on them or even how to use one. Here are a few tips to help you in your selection:
You want a dehydrator where you can control the temperature.
Commercial dehydrators without temperature gauges can be preset as high as 150 degrees.
Pick a dehydrator that allows you to manually alter its temperature to as low as 90 degrees.
Keep in mind how much food you will be preparing. For one person, a small 4-drawer dehydrator may be fine. If you’re preparing food for more than one person, consider larger models.
Rotate your food halfway through preparation time or as directed.
Consider getting a thermometer to gauge temperature.
Because you have it set at 115 degrees, that does not mean that is also the surface temperature of the food. For example, in an oven of 400 degrees, the surface and inside of food does not get to 400 degrees. Use you best judgment and feel free to err on the side of caution.
