Hello! I apologize for my English, this is all Google translator.Inspired by the idea of cold smoking, I decided to make my own smoke generator. As a material, I decided to use a stainless mesh. I think it will last me long.

Step 1: Smoke 1

First I made a smoke generator of this type. The time of his work is 5.5-6 hours. This product requires less material, but more difficult to manufacture. Also, to give the product a decent appearance, accuracy in measurements is required. I decided that although the appearance and does not affect the performance in the product should be a certain aesthetics.Therefore, option 1 had to be abandoned.

Step 2: Smoke 2

So, I went along the path of simplification. As I said, this option requires more material, but it is easier to manufacture.
As you can see in the photo, the design is extremely simple.

Step 3: Test

During the test, I constantly controlled my smoke generator. The photos are taken every 1.5 hours. My smoke generator went out after about 6 hours, without finishing it. I think he could work theoretically for about 9 hours.

In general, I'm satisfied. However, I do not like the quality of the smoke. Such smoke generators are suitable for a small volume. For a larger volume, several devices are required. In the future I plan to use pellets, I hope I will get better smoke.

I hope my experience will be useful. Good luck!
