great information yugamrap this is what I planed on doing, but I may need to look at Amazon to find something like you have. Always up for good ideas.
Search Amazon for:
Hood = "Update International MB-3000HD SS Mixing Bowl 30 Qt Heavy Duty"
Fan = "VenTech IF6 6" Inline Duct Fan 440 CFM"
Variable Speed Control = "KB Electronics Model KBWC-18K (UL) Variable Speed Fan Control, Wall Mount, Rated 8.0 Amps @ 120 VAC for use with Shaded Pole and PSC Motors"
