How much can you fit in a food deyhdrator at once? I was thinking of building the box fan/air filter "oast" but if it only takes a few batches I'd buy a dehydrator.
This is kind of why I didn't want to use the dehydrator, it only had a few trays where my oast can hold a lot more.
I figured out a solution though. Since I figured the problem was the low temperature I first tried adding a small space heater next to the oast. This didn't work well enough but when I covered up most of the back of the fan (I put the fan on top facing down) so that only a small space near the space heater was open, it only pulled in the warm air and this raised the temp. So I rebuilt the back of the fan with $6 piece of plywood from Home Depot with an opening for a mini space heater and the power cord only and hooked the space heater up to a temp controller. Kept the temperature between 85-90 and got my next batch of hops down to a 1/5 of the original weight in less than 24 hrs.
