500g Automatic Coffee Roaster Machine for Home Use with Smoke Fitler and Straw Collector

Ha funcionado bien hasta ahora. De fácil uso y de fácil cuidado

It took me two roasts to get it right. The first one burned the beans. Reviewing the instructions didn’t help a terrific amount, so I reviewed You Tube to get more of a hands on sense of how this roaster behaves. The second roast worked out very well! This beats my Gene Cafe by a country mile. Better more even roasts and a greater capacity.

I've been a home roaster for about 25 years. I've used hot air corn popper, the iRoast (i-roar), Gene Cafe and now this skywalker clone machine. This machine has some quirks but I've adapted it to be a very capable roaster. I'm using a TC4 Arduino interface with Artisan Scope open source software. This machine is great for a diy maker/hacker. I have full computer control of this roaster and can better track and reproduce roast profiles. The included controller works okay, but the user interface is confusing and takes practice. The auto-roast (mode 3) over-roasted a few batches, so I went with the computer interface instead. It makes a good bit of smoke, and I use it outside on a patio with one of the included vent ducts bent into an "L" shape. I don't use the electric cooler/filter. I made a few adjustments which help resolve some shortcomings of this machine. People complain of a few left over burned beans from previous batch -- that the drum does not fully empty when dumping. When I dump beans, I put a small 1-inch strip of wood under the back of the machine which tilts the end up so all the beans empty when I dump beans at the end of the roast. I keep the roaster on a 1-inch board which lifts up the machine and allows the cooling track to pull out easily. I put thick tape under the edge of the cooling drawer so the bottom metal sharp edge doesn't scratch my table. When cleaning after roasting, I use a small shop-vac vacuum to suck out the internal chaff bits, and use the vacuum exhaust to blow into the machine while vacuuming the sides. I get it really clean this way. The cooling fan works alright, but for complete bean cooling I remove the metal cooling tray with beans and place it on top of a small 8-inch round fan tilted to blow "up" onto the tray. The drum is single speed, which works well. It seems to require about 150 grams minimum load so the beans will touch the internal RTD sensor to register the bean temperature. The fan and heat settings adjust in 10% steps, so each has 0 - 100% settings. The separate "cool" mode turns on fans for the cooling drawer and is simple on/off button. The heating element seems to be an IR halogen tube. While it's roasting I can see bits of chaff stick to and burn on the bulb. I think it might reduce bulb life, but it's working now. The heater is **inside** the drum. Beans get radiant and convection heating which is PWM controlled. Sometime soon, I plan to replace the RTD Bean Temperature sensor (BT) with a thermocouple. I also plan to add an extra sensor for Environment Temperature (ET) which the unit does not have. There are plenty of forums and projects about hacking this style of roaster. Overall I'm very happy with the capability of this machine, and look forward to learning more about the craft of home roasting my own coffee beans. UPDATE (Jan 2026): I've discovered this machine Bean Temperature (BT) reads about 15 degress low when roasting batches of 150-200 grams. I reach First Crack Start (FCs) at around 172C. I use a flashlight to view the beans in the tiny window to look for Dry End (DE) or Yellow stage. The flashlight helps to verify no green is left, at around 150C. This machine uses Infra Red (radiated) heating (not convection or conduction via heated drum), so the beans will heat sooner than the probe. I burned a lot of beans pushing to BT=202C before realizing this. I'm now using batch sizes of 250gram which give more reliable (and still low) reading on BT probe. I removed and compared the existing RTD BT probe against two good thermo-couples with hot/cold water, and the BT probe is accurate. I still use and enjoy this machine, but which I knew about the low probe readings at first.

Sin duda un muy tostador de buena calidad, para unos tal vez un poco caro, pero sin duda que vale completamente la pena, yo lo compre para un emprendimiento de una cafeteria, para tostar mi propio cafe, afortunadamente el negocio prospero muy rapido y se me quemo el tostador en 1 mes exacto, tostaba 1 a 2kg por dia, pero dandole su uso domestico que es pera lo que es, vale mucho la pena.

I have been home roasting for the better part of the last five years, a journey that started when we got our Breville Barista Express. I spent most of those years roasting tiny 80 gram batches, but after many debates, reviews, and research, I bought this machine in February to finally scale up. For a machine that holds this much, the actual footprint isn't too big either. In a nutshell, I am really pleased and would recommend it to anyone looking to roast at home. It was very easy to set up, the control interface is intuitive, and the instructions are straightforward to follow. I have already run over 50 pounds of green beans through it from various parts of the world, including my favorite bean, peaberry. My absolute sweet spot for getting great, consistent results is right between 350 grams and 400 grams per batch. I choose to use the machine outside because of the smoke, and I strictly rely on the preset roast settings. The heat output is strong and consistent, and those presets have worked surprisingly well. It collects the chaffs really well in the tray, and my routine is simple. Now, I let it cool down enough between sessions and use a handheld blower or vacuum to keep it clean. Maintenance is a breeze if you do that. I also contacted customer support early on with some questions and was pleasantly surprised by their fast response time and the great attention they gave me. If you want a durable, reliable machine that delivers excellent results batch after batch, this is a great choice.
