Gojiberry,

I have been using food drier for couple of years now, it is Ezidri (a Newzealand product). It has some 7 stacking round tray with 3 regulator (mild, medium and hot air).
So far it works very well for drying all kind of stuff ( mushroom, fruit,herbs, chili...).

I slice the mushroom/chili/fruit to 0.3 to 0.5cm thick ( the juicier, the thinner, as it will shorten the time) before setting them to the tray and stack all trays together. Once they are dried , keep them in airtight jar.
