This winter I just sliced up my peppers and put them in trays and set them on the furnace register, this dried within in 3 days, I moved the sliced peppers around a couple of times during the days to prevent any molding. Put them into a bean grinder, ground them up and put the powder into small containers in the fridge.
I am too cheap to purchase a food dehydrator but have done the research and am going to purchase the Open Country 500 brand. $89 with jerky kit.
I did the comparison between the less than $100 dehydrators and found Open Country 500 had the most for the dollar value. It has temperature control unlike the $50 versions that just have the heater and fan, this way I can dehydrate foods as well at their specific drying temperatures. It has 4 trays but more important in comes with the spice/herb trays and fruit trays. Plus it comes with a jerky kit(if that is important).
The comparison I made was between Nesco 700 watt version and the Open Country 500 watt. Both are excellent brands and you wouldn't make a mistake by choosing one over the other, I just started adding up what came in a kit and to get the same items that the Open Country kit offers, I had to keep adding to the cost. Stay away from the cheap Salton brand, it has really bad reviews.
I found both Nesco and Open Country at Bass Pro Shops, Salton at Canadian Tire. If you have heavy volumes to process you look at the $200 plus units like Excalibur.
