Excalibur Food Dehydrators are well made, sturdy and reliable. They offer low temperature settings making them perfect for fermenting and culturing (counter-top yogurt starters, dairy kefir, kombucha or vegetable ferments) even when your home is on the cooler side (we suggest barley turning the temperature setting on for a nice room temperature setting). An Excalibur Food Dehydrator even doubles as a yogurt maker for culturing our Traditional Greek yogurt starter (or any other yogurt starter requiring heat). As a bonus, they are also energy efficient! According to the manufacturer, an Excalibur Food Dehydrator only use $.04-$.05 of electricity per hour!
