I had been looking for a while for a food dehydrator machine, but wanted to get you started is not equal to a high-end device purchase and therefore remain under a certain price limit. And I had seen many attractive models from which but each always fulfilled only part of my desires to such a device (because of the price range). If it had a protection against overheating, it lacked a thermostat. I also published three Dorr levels as too little. This dehydrator machine all my wishes are fulfilled (to such a device ...) and I'm from scratch satisfied. He purrs relatively softly to himself. At about 1 mtr. Distance I measured 54 dB. The plastic grates feel quite robust, in the dishwasher I would not do it anyway. As a rule (eg, apple chips) but also extends the mere wiping with a damp cloth. Only humid Food to be dried (z. B. strawberries) leave more tracks. The whole surface is dried enough for about 8 Medium, thinly sliced apples. For crisp apple chips the device needs about 8 hours. The lack of time switch can be easily compensated with a small switch on the socket. The dried layers can be varied in height, so that they are prepared for thicker pieces. To the obligatory repackaging the lower Dörre days (which is rather dry) on the upper level, one comes here for technical reasons, are not around. But it is done quickly with a few simple steps and is available in the dried process only about 2-3 times necessary (depending on the food to be dried). The lack of evidence on Dorr times for various food to be dried, in the lean operating instructions, I have not missed. The table at the front of the device is sufficient to start with. Ultimately Dörren is indeed a bit like baking cakes. Until you can touch the dough by feel, and know, how much "bite" the oven has its own, you have to try around a bit, yes.
