Optimal utilization is at all levels to shift by about half of the time the soil from top to bottom. This is possible during normal operation, as the device is only warm, but not hot. So everything dries nice and even. Nevertheless, you should check every now and then and take out already finished Dried, thereby possibly distribute the rest to less floors.
The device is suitable even for something richer fruit juice because floors and tub are easy to clean. We have chokeberry (Aronia) tried it, have become very beautiful. Although there was some out dropped, but could be removed easily and without any residue or discoloration.
Next, the cranberries is their turn. I'm very excited. For us, the Severin-fruit dryer was a really worthwhile purchase.
