How long does it take to dehydrate a banana? I have heard that it takes 10-12 hours. Do have a dehydrator that takes less time to dehydrate.

The Excalibur dehydrators we sell have an adjustable thermometer, from 85 degrees to 145 degrees. Most dehydrators do not have an adjustable timer... The hotter the temperature, the less time it will take to dehydrate (a banana) or whatever you are dehydrating. I recommend to preserve nutrients, and enzymes in the item you are dehydrating to keep the temperature around 100-105 degrees. If you dehydrate at a higher temperature, it will work, and be done faster, but this is at the cost of losing nutrients, and killing the enzymes in the item being dehydrated. Bananas usually take from 6-10 hours.. Fruits take from 6-10 hours (bananas) to as much as 22-30 hours (for plums).. Vegetables take from 3-7 for mushrooms, to as much as 10-14 hours summer squash.
