JIAWANSHUN Coffee Roaster Upgraded Electric Coffee Bean Roaster 1.1lb Coffee Roaster for Home Use,0-240℃ Temperature Adjust&Timer 110-120V

My first 2 roasts were 300 g regular Uganda beans and 300 g of swp decaf Sumatra beans. I roasted outside ambient temperature 55 f. Roast profile was based on time and bean color. I tented the roaster with welding blanket due to outside temperature. Dried both roasts for 10 minutes with the Ugandan beans at 170 c on the dial and decaf at 160 c. I gradually raised the temperature on both, Uganda to 230 c and decaf to 210 c. Total roast time on Uganda was 26 minutes and decaf 24 minutes. Uganda came out a nice medium roast but the decaf was a light roast, looked medium but tough to grind. Mixed the 2 and coffee was great. On my third roast I decided to mix the Uganda and decaf Sumatra and roast them together, 150 g each. This time I decided to use infrared thermometer gun to roast by temperature. Roasted outside in 40 f with welding blankets on top and bottom of the roaster (placed roaster on cookie sheet with blanket under that). Dried the batch for 10 minutes at 170 c on the dial then set the dial to 225 c and monitored the surface temperature of the beans till they reached 415 f. Total roast time was 24 minutes, came out medium roast. Great.

Pros: Can roast up to 1.1lbs of coffee beans at once. Easy to use with adjustable temperature control. Consistent roasting results. Compact design, great for home kitchens. Cons: SMELL is very strong so expect it to linger A bit noisy during operation. The roasting process takes some time, so it’s not the fastest option. Experience: I’ve been using this roaster for a few weeks, and it’s been fantastic! It’s easy to use and gives me great results every time. The beans come out perfectly roasted, and I love the control I have over the process. Who This is For: Great for coffee enthusiasts who want to roast their own beans at home and enjoy a fresh cup every time. Final Thoughts: This coffee roaster is a great value. It’s easy to use, provides excellent results, and is perfect for anyone who loves fresh, homemade coffee!

Update 7/2024: The newer version of this roaster gets hotter, faster. 10 minutes at 170 to dry them out, 8-12 minutes at 240 to roast depending on what you like roast-wise (I like a medium roast just into second crack). The first batch will roast faster than subsequent batches. I don't use the welding blanket anymore, it gets plenty hot on its own now. Original review: This coffee roaster is so-so out of the box. It functions like an old whirley-pop popcorn maker from back in the day, with a non-stick base and a rotating blade that agitates the beans. Its major design flaw is that the glass lid, while sturdy, does not sufficiently insulate the roaster to get the beans hot enough to roast them to proper coffee roasting temperatures. You can barely get them to 200 degrees centigrade after 45 minutes or more, even at the hottest setting. However, get yourself a welding blanket (https://smile.amazon.com/dp/B019SWRT0E/) and this roaster goes from so-so to outstanding. You can roast 300 grams of green beans in about 45 minutes. I recommend setting it to about 180 degrees centigrade with the lid on for ten to twelve minutes to drive out moisture. Then, remove the lid and wipe off the condensation. Replace the lid and turn up the heat to 240 degrees. Place the folded welding blanket over the roaster. Set your timer for 30 minutes. (This is far too long on newer models; see second update) After that, come back and check the temperature (using your infrared thermometer) and color of the beans, based on roasting charts you can find on the internets. If they aren't done, continue roasting in five minute increments until they reach the desired temperature and color. A note on smoke: many reviews talk about how smoky coffee roasting is, as though your neighbors will call the fire department on you if you roast coffee. This is nonsense. Yes, there is some smoke, but it's nothing terrible. Just roast your coffee under your stove's hood, and turn the fan up to at least medium, and you should be fine. So, I knock off one star for not functioning as designed out of the box. But add a welding blanket, and this roaster works great. Green coffee beans are very inexpensive, and unlike roasted coffee beans, green beans keep for years in a cool, dry place! We haven't bought roasted coffee beans once since we figured out how to use this thing properly, and it has easily paid for itself. Update 7/2022: After just under three years, the heating element is starting to wear out on this device. Even turned all the way up, we can no longer get my coffee roasted at the stage we previously did. This seemed to happen very suddenly - one week it worked fine, the next week, not so much. So, still a great value, but it looks like we'll need to replace it soon.

I've been roasting my own coffee for over 10 years. My method was in a stainless drum in my BBQ. The drum is having serious issues after all this time and it is now $260 for a new drum. I found this for under $100 and decided to give it a try. It came today so I set it up and threw in 1 pound. 25 minutes later I have a perfectly roasted pound of coffee. If you like a lighter roast I'm thinking it would be 18-20 minutes. Color me impressed and hoping it lasts. The arm that rotates the coffee did a great job and nothing got stuck and burned. I was able to see the beans the entire roast so I could gage the exact time to remove the batch. With the BBQ I had to gage by sound alone so seeing the beans was really nice. A wet rag after the unit cools is the only clean up. I'm absolutely thrilled! If you want to roast your own coffee I would highly recommend getting this and giving it a try. Lastly, for those who haven't roasted before it does give off quite a pungent smell. I love the smell but wouldn't want it in my house so I roasted out on the deck.

This product is not worth the price, maybe if it was 20.00 it would be worth a try. No automatic timer built in... My toaster oven from 1992 has a timer. It doesn't alert you when it gets up to temp. The quality of the roasting arm is cheap and the tolerances to the pan are not made well, which means you have to bend and adjust the bar so it doesn't scrape the pan, which then causes beans to go under the rotating arm which puts stress on the assembly and cause a lot more burnt beans. Would not buy again, and would not recommend.

Having used various roasters before, I recently pan-roasted for a few months with good if laborious results. I wanted something simpler but affordable. This unit has worked perfectly with all varieties of green beans I've tried. Running unit outside, I preheat at max with lid on for 15 mins, then add 400-450g of beans & set 35 min timer, leaving unit undisturbed. When timer goes off I check & when color is to my liking, I lift lid & use a fan to blow off chaff for a minute or so while unit runs. I try to avoid nonstick but for this I imagine stainless steel would require a lot of cleaning. The base portion stays very clean.

My daughter and I wanted to start roasting our coffee beans at home. After much research, we landed on this roaster. It was an outstanding balance of function and price. When I received the roaster, I couldn't wait to start using it. I found the instructions lacked detail. After some trial and error, I finally got the lid together properly, as it was not explained. For our first batch of beans, we followed the somewhat vague instructions in the manual. The result was beans that were beyond a city roast on the outside, lots of shells, and then a green inside. We logged our heating and timing to make the appropriate adjustments for our next trial. Determined to make it work, I looked for videos that offered more detailed instructions. We adjusted our cooking and heating times and had the same results. On our last attempt, we tried another bean, concerned that it wasn't the roaster and the bean we had selected. With a few adjustments to timing and heating based on our last results, we roasted our final batch. The results were the same: an uneven cook, green inside. We returned the roaster and received excellent customer service from the small business selling the machine. I do not feel it was any reflection on them; perhaps we received a bad heating element with this particular roaster. We have since transitioned to a popcorn-style roasting machine with excellent results. I really wanted to love this product; we just couldn't get it to work.

I used to use a popcorn air machine to roast my coffee. While air roasting is cheap and pretty effective, the amount you can roast is extremely low. This roaster is the first of its kind that I’ve used and I’m very pleased with it. Let’s start from the beginning. 1.Package was very good and product was well protected during shipping. 2. Instructions were extremely basic and used Celsius. I roasted mine at 180 for 10-15 min for a French roast. 3. Well made but basic. I do appreciate the glass lid rather than plastic and the nonstick surface makes clean up easy. 4. It came with a timer that was in Chinese but still easy to use 5. The volume you can roast is still something I’m playing with but first batch was a little under a pound and the evenness of roast was decent for sure, 6. Only downside is that it does not agitate the beans like an air roaster but if you manually agitate by moving the machine around like a frying pan you will not only get a more even roast but also help with the removal of the chaff. 7. I am over all extremely pleased and will purchase again in the future if this one goes down!
