If you are talking about the dehydrator. Make a cylinder out of card board or flexible sheet plastic(rigid not poly) the diameter of the dehydrator and taller than your bottles. Set the bottles on the dehydrator bottom. Put home made cylinder around bottles and put on dehydrator top. If the dehydrator has variable temp set it between 100-120 deg F. 12-24 hrs it should be crystal free, maybe even sooner. Dorm style fridge(preferably a cheap one that doesn't work) with a light bulb(on bottom with heat shield directly above) hooked to a thermostat(with sensor hooked underneath bottom rack) set at 100-120 deg F. Stack bottles on racks above heat shield(don't over load with to much weight). The larger quantity you need to do the larger you make your decrystalizing device. Rack style upright incubators work also as do these devices I described work for incubators. As stated in post #6 works you can also use a water bed heat pad as it has a thermostat and sensor probe already and you can place that on the bottom of any enclosed device you wish.Beeslave could you be more specific on the way to decrystalize? .
