Yes, you can dry different kinds of fruits or vegetables at the same time. Just make sure that each kind passes the test for being dry. It may increase the amount of time needed to dry all of a particular kind of fruit or vegetable. If you are drying soft vegetables and hard ones at the same time, because the soft vegetables need a lower drying temperature, use the lower setting until they are all dry, then boost up the temperature to the higher setting to continue drying the hard vegetables.
