I add one more fan adapter
One fan is for fire basket for burning
The second fan is for blowing in more fresh air for ventilation when dehydrating fruit/vegitable
Also I add 3 more stops for grill. Totally it will have 5 grills. More grills are used to do dehydrating or do jerky.
1.It is a UDS smoker
2.by removing umbrella, it is a common grill
3.by adding more grills and an extra fan it is a dehydrator
