Clean them with fresh water, just as you did in the oven drying method. Slice them along the indentation with a paring knife. Remove the pit and discard. Leave the skins on. You need to press the outside center until the flesh spreads out. Spread the apricots onto the racks with the flesh facing up. Make sure there is space between each piece of fruit for increased airflow. Set the dehydrator at 135 degrees Fahrenheit (57 degrees Celsius). Read your manual to determine if this is the low, medium or high setting on your dehydrator. Larger apricot halves will take longer. Place them in a cool, dark place, such as a pantry. They will last several months.

Summary:
Choose your ripe apricots. Pit the apricots. Separate the halves and turn them inside out. Remove your dehydrator racks. Replace the racks. Wait approximately 12 hours or until the timer goes off. Store dried apricots in sealed glass canning jars.
