Sandbox Smart Coffee Bean Roaster Instructions
1. Before roasting coffee beans, please make sure you are familiar with the location and
operation of the following parts.
1-1 Make sure A – inlet for green beans opens and closes properly.
1-2 Make sure B – bean-output door opens and closes properly. Flip up the latch and
ensure the door opens about 10˚ for roasted beans to drop out.
1-3 Make sure D – the roasted bean tray opens and closes normally.
1-4 Make sure I – the chaff collection tray opens and closes normally. You must wear
heat-insulating gloves to open the chaff collection tray as it becomes very hot.
Please remove all chaff after each roast, or there may be a possibility of excessive
overflow of chaff that may produce smoke when next roasting.
2. There is a “preheating” function for standard bean roasting, but
do not rush to pour green beans into the roaster. Follow the
instructions on the App to complete the machine preheating
process, and the App will let you know when to pour in the green
beans.
3. Make sure you know what “first crack” and “second crack”
sound like. The “first crack” sounds like popcorn popping, while
the “second crack” sounds more subtle. This will be the most important judgement basis
in the process of roasting beans. Please watch the video by scanning the QR code on the
right.
4. We recommend using the official profiles for “light roast” for roasting beans to have a
better understanding of the performance of this device. We do not recommend using the
“dark roast” beans or setting manual profiles, as this may lead to high temperatures if you
are not familiar with the product and may result in over-roasting the coffee beans.
5. During the process of roasting beans, it is normal to have occasional sparks caused by
chaff igniting due to the high temperature. Please do not worry.
6. After you become familiar with how this roaster works, we suggest you use the official
profiles as an example to set your own profiles or parameters to improve the flavor.
7. When designing your own roasting profile, to reduce the failure rate, we suggest you set
the parameters to after the first crack/second crack as follows:
Following the above advice will effectively enhance the success rate and flavor of roasting
