Hmm well what I am actually heating is a stream of air that is going to be piped through a small tube that is the diameter of a quarter or pill bottle The air which is heated to the desired temperature will be blown through the tobacco product. From personal experience with similar products a stream of air heated to the desired temperature and blown at a decently low speed past the product will cause vaporization. I am not sure on the exact CFM, but I can't see it being more than a PC fan
I do not have a strict tolerance. I assume that varying the power to the element on\off would work fine (this is how most vaporizers work). I just want to get in the ball park.
Here is a diagram of my intended design:
I will determine my distances between the element, product, sensor, and fan as well as fan speed experimentally ;).
I'd like to know some of the theory behind this though. Could anyone point me in the right direction of what equations I would use to calculate these things?
