Thanks for the info on the drying of the maters.....
I need to scoot for a couple hours, but will further reply to you when I get home later.
Forgot to mention :
At least w/my dehydrator, I cannot get a 2nd tray on until the first tray of tomato pieces has dried enough for there to be room above them for the next tray to fit. So, when starting, it may be 5+ hrs or so before you can get a 2nd tray on and so forth for the additional trays. Also, once you have several trays on the coil, you will be able to consolidate the pieces that are the driest on to one tray and as soon as the contents of the 2nd tray are dried enough for another tray to fit above it, that tray can then be moved to the bottom, closest to the heat source. Within a day, you will have all 5 trays on the dehydrator and you can simply slice up more tomatoes for the topmost tray as you remove dried ones to the oven.
Hope that makes sense.
