Not sure what they are called, so i gave it a name. picture attached at bottom.


I believe this machine would be the equivalent of a Whirly Pop but on electricity.
I haven't found anywhere that talks about roasting with this machine, or a modification for it. Perhaps the pages are lost between all the air pop machines.

I was wondering :
1- what is the taste profile difference between this and an airpop (if both were not modified)
2- which one would produce a better all around profile (if machines were modified) ..
3- does anyone know of any links or ideas to modifying this machine. My general idea: something that controls the amount of wattage or volts such as a dimmer to control the heat. so would it be the same mod as the airpop but without the seperation of fan and heating element since i dont think these oil machines have fans.

I really appreciate your thoughts,

Layth

Interesting thought, but I don't think this plan is practical, efficient or even workable.  Even though these machines use a rotary stirrer to move the corn, the power (watts) required to roast even a small amount of beans within a reasonable amount of time, isn't there.    At least a couple of different machines I've looked at are under 900 watts.  Dedicated home roasters such as my I-Roast, the Behmor, and make-do custom roasters such as the HG/DB design are rated around 1500-1600 watts.  Trying to roast coffee with too little power will cause an extended roast time which will bake the beans instead of roast them.

Might be a chance to get results with 1400 watts.  Go crazy with it and see what you can work out with a new design that might change the world!!

With all the heat energy directly into the pan and no convection fan, you will need to get the beans really moving in the pan for even heating and to avoid scorching. I'm sure the popcorn stirring will be way too slow. The beans need to tumble.  That and good temperature control could make it into a coffee roaster. I would prefer a roaster with good convection control though.

The whirley pop stove top does a decent job of roasting so this might as well with out all the cranking. Could be fun to find out.
