Hi guys!! I'm new to this forum....I have been trying to use an existing pop-corn popper to home roast my coffee. However, the problem I have is two-fold,
1 It is pretty loud and smokey (so I was wondering how to solve that, maybe adding a smaller vent fan somewhere, in addition to the fan it has?) Where should I wire the fan/filter in the system (attached circuit diagram) or what else can I do to solve this.
Most importantly, it gets too hot, too fast! There is no control. Hence the necessity for a switch, or timer. The switch could be a high-low setting, or the timer could be a 1 minute to 10 minute increment. I looked at some off-the-shelf timers, all I need to know now is how to wire it to the appliance circuit (see diagram attached). Can something be wrong with the thermostat? What other ways can I fix this issue?

I've never used an air popper roaster, but if you do a search for "popper mods" (search feature upper and lower right of the screen on the main forum page) you will find a wealth of information. Mostly in the "Home Roasting Talk" section of the forum. Welcome to CoffeeGeek!

A lot of people solve the smoke issue by roasting outside. Temp regulation is always a problem when making an appliance do a job it was not intended to do. Some roasters get around this by using a variac to control the voltage to the heater coils. They are expensive but work well. You will also need a device to monitor the temp of the roast, a digital thermometer using a thermocouple is most often used.
