  • Rated 5 out of 5 by from 48 hour timer and 2 time, 2 temperature Absolutely loving this dehydrator. Especially the longer timer setting and the ability to set 1 temperature for 1 time and then a 2nd temperature for another time. So for me, trying to stick with the raw food guidelines, it's really making dehydrating a lot faster and the food isn't getting hot and losing the nutrients, etc. My apples take about 2 hours less time in this. Love you for carrying Excalibur.
