Learn how to dehydrate your chili peppers with a dehydrator and grind them into homemade chili powders. Here is the recipe method, from the author of "The Spicy Dehydrator Cookbook".

How to Dehydrate Chili Peppers and Make Chili Powders
Dehydrating your chili pepper harvest is an excellent way to preserve your peppers. You can easily crush them or grind them into powders for use all year long. The method is very simple with a dehydrator.
Check out the video below.
What can you do with your dried chili peppers?
Grind them up to make your own chili powder, which is like cayenne powder, or keep them whole and use them as you might use a sun dried tomato.
They can be rehydrated with hot water and go great with many chili pepper recipes.

How to Dehydrate Chili Peppers to Make Chili Powders and Seasonings - The Recipe Method
First, wash and dry your chili peppers. Choose only fresh peppers. If they show any signs of rotting, throw them away.
Next, wearing gloves, remove the stems and slice the thicker peppers into rings and thinner peppers in half. Leave them whole if you prefer, but they will take much longer to dehydrate. The gloves are important when working with peppers because the oils from the peppers can burn your skin, and the pain can linger.

Place the peppers on the trays of the dehydrator. Spread them out evenly so the heat can distribute properly.
Turn on the dehydrator at 135-140 degrees F, or whatever setting your dehydrator recommends.
NOTE: I like to place my dehydrator in the garage because it will release fumes over time and you will notice the odor. Let the dehydrator sit anywhere from 5 hours to overnight.
It will very likely take longer than 5 hours, but much depends on the thickness of the pepper walls and how many peppers you're working with.
I personally turn mine on when I go to bed and check it in the morning. The peppers are usually dried by morning, but if not, just leave them in longer until they are dried.
Once they are dried, remove and grind them into a powder using a spice grinder. Some people have a separate coffee grinder dedicated to grinding peppers.
Strain out the powder and process the larger chunks until only chili powder remains.
Safety Advice
When working with hotter peppers, including superhots, it is important to wear gloves when handling the peppers both in raw and dried forms. The oils can get on your skin and cause burning sensations. See above.

Also, the powders are quite fine and may get into the air if you are not working in a well ventilated room, so you may want to wear a mask and goggles. Superhot chili peppers, truly, are called superhots for a reason.
Storing Chili Powders and Other Fresh Seasonings
Store the chili powder in baggies or containers, or use as you wish. Keep it in a dark place, like your pantry, for freshness.
How Much Chili Powder Comes from Fresh Peppers?
1 pound of fresh chili peppers will yield about 4 ounces dried pods. Ground down, it should yield 3/4 cup chili powder.

I dehydrated in my oven, it has dehydrate setting. I set temp 10 degrees lower and let them go for roughly 24 hours. Perfectly dry and made a fabulous powder that is great! I used container Tucson grown Hatch mild peppers . Keep my plants going year round, oldest plant is in 3rd year of production and produces continually. Just harvested 20 popper size peppers yesterday from 3 plants.

May I dehydrate peppers in the oven?
Thanks, Jan

Hi, Jan. You may, but don't go too high on temps, or the peppers will burn. Avoid direct heat.
