Coffee Roaster Gas Burner Coffee Roasting Machine for Home Use, 400g Capacity, Quartz Glass Drum, Stainless Steel Frame, Peanut and Nut Roaster

Ok I'm new to roasting coffee, but not new to the concept. The only reason to do this at home is to have unmatched flavor and quality control over the coffee you drink. I do not think home roasting is necessarily a huge money saver, even buying green coffee in bulk. Good coffee is hand picked and in high demand - so it's going to be expensive regardless. The roaster itself works, it's solid, and has a nice capacity - directions suggest 2 cups per roast cycle. I wanted a roaster that I could use on a weekly basis, preferably outside, and preferably using propane. This roaster fits that ticket. I did not want a small electric table-top variety where I would have to roast beans several times a week or daily. I've been using this roaster weekly for past 6 weeks. Process is as follows. I do 2, 2 cup batches once a week (1 quart, roughly 500 gr), usually on the weekend, on the back porch using a propane camp grill. This roaster worked fine in the house but i don't need the extra heat and the chaff does blow all over the place and it's annyoing to clean up--so strongly recommend this as an exterior unit. The two batches, back-to-back take about 45 minutes. I start the flame at medium high and then cut way back once the beans start smoking just over 400. The thermometer provided is very useful, attachment is a bit clumsy but overall simple to operate. I usually sit and loosely attend the roast, doing other things while it's running. After roasting each batch, I winnow the beans between two bowls in the wind to remove chaff. I do not clean the glass after every use as suggested, just too much work. Instead I've cleaned it about once a month using damp paper towel dipped in hardwood ash from my wood stove. The roasting deposits a brown patina / soot on the inside of the glass, which minimally impacts the view. Overall, I'd suggest this product strongly for anyone looking for a weekly roasting solution using propane burner outside or in a garage--and with enough cabinet or shelf space for a moderately bulky item. Again, the objective here being the experience and joy of freshly roasted coffee, not that old stale stuff sold in the grocery stores. This product nails the roast with its consistency, simplicity and capacity.

This works really well, except for smaller beans, which will get stuck in the metal tubes and burn, causing a lot of smoke. Additionally, I feel the product is far too expensive for what it is and it is rather bulky. Still glad I have it, but if I need another roaster in the future, I will definitely look into other options.

I've made about 30 pounds of coffee so far with this. I typically make five pounds in an hour or so in 400 gram increments. It is a solidly built item. I've already broken the glass once and have since purchased a replacement. I dropped the glass into the sink during washing. I recommend washing in a large plastic bowl with an SOS pad. Keep the glass in the bowl while scrubbing to avoid damage. I tried a basic camp butane burner but upgraded to a propane burner for the BTU power. Roast outdoors, it will produce smoke and stink up both you and your house. I engineered bean cooling after the roast to stop the reaction. There are some unofficial YouTube videos that are somewhat helpful. You cannot use a laser thermometer for this, we tried and it's not useful compared to the included thermometer. You can get a dark roast in under 13 minutes, about 10 for a medium. Can you get better? Yes, but at 10x the cost. This is a good entry-level roaster.

It’s pretty basic, but the base is well built. Motor ran fine for first roast ~3hrs straight 50g-150g roasts. Wow, this probably maxes out at the state of 400 g. I don’t think I would roast much more than 300 g. The roasting drum supports are interior made of steel and seemingly well built. They help provide agitation for the roast and support the glass a little bit. Removing the glass for cleaning is a little precarious though. The thermometer is basically a joke. It’s too slow to control temperature and mount is completely worthless. Ideally, you would be able to measure the temperature of the beans internally I ended up measuring the exterior bottom of the glass. I don’t think the amount is well suited for having a better fixed the thermometer, but will try that next roast. The roasting drum effectively just sits on the turn gear and a couple bushings on the other side to keep it smoothly rolling. I did apply a bit of oil to the gears and I think the other contact points might need heat resistant food grade oil for long-term use. Fits over a standard propane “stand” burner well, there are some slots on the side closest to the motor to allow some of the chaff to escape so it does get a little messy

It was easy to put together, stay cool wooden handle, amazing to watch, one little thing that was a little messy as the beans spin some of them can bounce out of the drum because of the small opening to the roasting chamber, do you have any ideas on how we can keep the beans in? Perhaps a small heatproof mesh wire cover that still lets steam out ? We tried tinfoil with holes poked into it, and it only worked a short while. Other than that, I really love this roaster. I have a gas stove and it sits right on top of it, I set the gas on 6 and set the stopwatch and it took approximately 20 minutes to get a nice light brown 1st crack beans, we let them cool and we wanted to test out the taste so we grinded up a few tablespoons. Our house smelled like chocolate, and the flavor reminded me of a dark chocolate flavor. Delicious.

Works great. Note: There are quite a few comments about not being easy to clean the glass. Do yourself a favor, grab some Barkeepers Friend. It cuts the stains wonderfully!

If you are a “small-batch” home roaster, this item works beautifully. Since the tumbler is glass, the desired roasting stage is easily observable; no more over/under roasted beans, or burned spots. The unit is solidly built, the end opposite the handle is cradled on rollers, stainless steel. Some particulars: The demo videos I’ve seen show the roaster used on those little portable butane/propane single burner camp stoves, which work fine, but what happens if the little LP canister runs out in the middle of the roasting process? Can the canister be changed out while the beans are still hot enough to finish without degrading flavor? Maybe the kitchen 4-burner gas range is a preferable heat source, or so I thought. What I discovered is that my kitchen range burners have a circular flame, which pushes the heat outward, not in the middle where it’s needed, directly under the glass tumbler; and the smallest burner was not hot enough to reach a French roast. - No fault of the tumbler! The solution to this was to place an old metal embroidery ring (4-1/4” X 1”) around the burner, which forces the flame upward, perfect! Of course, vintage steel embroidery rings are scarce, but Amazon has a variety of stainless steel cutting rings, i.e., biscuit, scones, cookie, crumpets. See fotos (2)

Well made and sturdy, mechanically impressive. Electrical connection is a cheap ac/dc converter similar to laptop power supply but the dc plug fits loosely and vibration has caused intermittent stoppage. Roasts using the recommended gas stove take nearly an hour, not hot enough, and uses a lot of gas, the little cans are expensive and add significantly to the cost of a pound of coffee. It’s hard to hear the cracks. Finally, and most importantly, the beans don’t seem to be evenly roasted. I did better with a hot air popper, although it was limited to about 120 grams in 12-15 minutes, so the time technically works out about the same. I’ll be looking for a better roaster. Update: I got a fluid bed type roaster and it burned out on the first run, so going back to this one, the roast taking so long I left it unattended for about ten minutes. When I returned it was billowing smoke- the motor had stopped due to the lousy DC plug connector. This is a serious issue. Uploaded video demonstrating problem.
