I've been tweaking designs for a hybrid electric/charcoal cold smoker. The current plan is to use a vertical 55gal drum, on a plybood base, with casters to make it mobile, and to get it off the ground a bit. There would be a hole for incoming smoke at the base, along with a 750 watt electric single burner element, to keep it from freezing in the winter, and allow warm/hot smoke if required. I'd put in an access door to allow me to adjust the temp on the burner, and install a drip guard/smoke diffuser between the base and the main smoke chamber. Then for the smoke, I was going use a 12 gallon barrel, about 6 or 10 foot away, burning charcoal and wood chunks. I'd duct the smoke with wither stove pipe, or something similar. Questions I'm having: 1. The burner's heat control is on the unit itself. Is the 250 dagree temp of hot smoking going to hurt anything? Likely not going to use it for hot smoke very often, but having it be flexable might be useful. 2. Is a single 750 watt element going to get me to the temps I need? I figure I can wrap the smoker in a moving blanket, or similar, in the cold of winter to help it not loose heat so fast through the sides. 3. Am I missing anything? Thanks!
