Question: Can I easily test the temperature in this unit?
Document: I cannot notice the sound at all 3ft away from the machine. I dried 3 trays of lemon slices as a test run. The results were beautiful! I feel like a little kid in a candy store wondering what I can cut up next to put in there!The back of the dehydrator comes off easily but holds firm with the latches in place. The front loading door is a bit loose but I simply pushed and slid the door down to check for gaps, then made a tiny adjustment.
Just unlatch the back and everything else is completely washable. Just re-hook the latches,and the guides slip back in easily. I love the fact that I can set the dryer for up to 15 hours.After setting it up, I immediately started drying things.
More, in fact, because it is easier than I expected it to be.The reviews claim that the dryer is noisy, but mine is not. At about 4 feet, all I can hear is a faint air movement - it's a whisper. The front door does not fit tightly. I feel that this is part of the design, to increase airflow. I do not want the temperature to get high.
Therefore, this design works fine for me. It does not rattle or make any noise. It dehydrates well, the timing can be monitored easily and set to prevent over drying. The shelves have a one-inch grid, which works fine for large pieces, but it also comes with two silicon mats for leathers and small pieces. You can always add parchment paper or screening if you use a lot of small pieces.Someone complained that there are sharp edges.
Heater was breakdown within a month. So I had to return the heater unit. But I hope the replacement is OK.
So far so good. I had a much more expensive commercial model that kicked the bucket. So far, this model is fulfilling my needs. I will update as a the unit gets more use.
This will create a three point support to prevent some of the rattling.- I might try a high temp silicone foam tape between the fan unit and the main box to isolate some of the vibration.- It's metric.
So glad I bought this dehydrator. was working with a much smaller model mostly made from plastic. I like having stainless steel. The unit is very efficient; I can get so much more done in a shorter period of time.
I received a unit with a defective door and the heating unit does not work at all, it only blows cold air. So far, mercantilestation has been working with me on the door, waiting to hear back on the motor. What a waste, very expensive and I've wasted food that I bought specifically to dry in this, that does not dry at all.
You need to either use a heavy wire gauge cord or plug the units cord directly into a properly ratedoratedoutlet for the unit.I am happy now and will be returning the original back, back to the seller wIthaca the ups shipping tag they sent. It's not costing me an extra dime, just a little time.
Answer: You can poke a thermometer through the slates or in the small gap between the door and the body of the unit.  The temp is not too stable, it hovers around the set temp, but is fine for most dehydrating needs.
