Thread: Coffee roasting video

this was interesting... at the end he talks to the color not being as black as they look. I cannot see any oil as they looked dried out... and I now want to know how it tastes. Seems to be a little bit of a tease.

Very cool! I use a Whirley Pop on the stove-top or a Poppery II electric pop corn popper

I use a HotTop D that I refitted with the B electronic pack so I have control over the heater/fan controls and added a type K thermocouple in the bean mass so I can data lot the roasts on my Fluke. How long was that roast form start to end?

I did not pay specific attention to the time, however it was approx. 15 - 18 minutes.
I went more by sound, temp., and color. I've found color, sound, and temp. comparisons
with the particular thermometer i'm using and 450 -455 degrees usually gets this particular bean to where i want it.

That seems like a good idea. How hot does a bread machine normally get without any modification? What does it use to produce the heat with? I had an i roast 2 at one point and I remember that it would make for a relatively clean and bright cup of coffee. I think that some of that had to do with how well it vented the smoke away from the beans. How much chaff are you having to deal with? Does any make it out through the top with the heat gun where it is?

Bread bakes at about 425 so i would think that is what it would heat to, however that may take some time and i do not know of anyone that uses this method only to bake the coffee.

The Heat gun.

some comes out the vent hole, but most stays in the machine, It does produce plenty of smoke so I roast outside or in my open garage. I'm trying to think of a way to vent the chaff. Maybe cutting hole at bottom -side to heat from below and cause the chaff to vent upward more readily from the air flow going up instead of down.

PM me if you want to try this method

Is the bread machine providing any heat at the same time as the heat gun? Does it have a built in heating element? Maybe you could force cool air across the beans while they are being agitated in the machine to cool them off a little quicker. And if you put some kind of filter/screen on an exhaust vent, that might catch the chaff if you are doing it in your garage.

The heat gun is the only source of heat.
The bread machine is used basically only to agitate the beans and contain the heat. Before i had the bread machine I just used the heat gun, metal mixing bowl, and wooden spoon to agitate. People in camp grounds came from all around when thye roast started giving off that great roasted coffee aromas. Does it have a built in heating element?

Just dumping the beans cools it quickly enough to stop the roast.

It's not that much i just vacuum up after.

I just started using this method after 4 plus years of Poppery I roasting, and I can seriously say (as our English brethren are wont to) that this method is the dog's bollocks!

i can roast 500 grams of green coffee in about 17 minutes. The roast is a little less bright than a popper, and the extra capacity is very much appreciated. I can roast nearly a weeks worth of press pot coffee for my wife and espresso for me in about 35 minutes (two batches back to back) so less time hunched over a popcorn popper and more time pursuing the finer things - like collecting straight razors!
