Has anyone used a Leister hot air blower to roast coffee and if so, which model did you use? What was your experience like?

Helical Drum Vane Radius Formulas


The calculations give you one vane traveling 360 degrees. For calculating the radius values for a vane only traveling 90 degrees (for a 4 vane drum) Im assuming you will need to use (pi x diameter) /4 in steps 1 and 2 for the right triangle base.
