Q&A

Please prepare a pair of insulation gloves, brush for chaff cleaning. DO NOT use plastic brushes as it will melt and contaminated the chamber, or clean chaff after system fully cool down. You will also need a electronic scale to measure green beans, and a cooling tray (with fan will be better to speed up the cooling process of roasted beans)

Sandbox Smart R1 Roster suggested for 200g-550g, there will be slightly smoke if you choose dark roast. Please just turn on your extractor fan or use Sandbox Smart F1 Filter.

It is safe compare with gas or fire heating, but we still suggest that user need to be around the machine during roasting process. Please read our user manual for procedure and safety reminders. Do not touch the body and view window of the system when using it.
For door handle it can withstand 280 degrees of heat.

The 110v and 220v machine will have some voltage compensation to meet your household voltage, but basically there is no different. However, due to the difference in current power supply in various regions, there will be slight differences in firepower.
If you receive profiles of different voltages from your friend, you can adjust the profile’s voltage setting to your own preferences. It is recommended to fine-tune your 1st crack setting if you are using profile from different voltage.

Flip-up the opening of the bean output door and beans automatically fall into the tray. 
(Note: To close the output door, simply hard press both sides of the roasted bean doors)

Please clean out the coffee bean chaff after each use to avoid residual chaff from catching fire.

1.Put on gloves and take out the roasted bean tray.

2. Take out the chaff collection tray.

3. Make sure there are no sparks on the chaff, then pour it into the trash.

4. Reinsert the chaff collection tray, then roasted bean tray.

When roasting process is finished (after you take out the drum and close the front panel), Sandbox Smart R1 Roaster will start cooling itself. If you would like to continue roasting, you can manually select “Stop Cooling” and start another batch.

1. Before cleaning, unplug the power plug and make sure that the product is completely cool down.
2. Do not immerse the product in water or splash water on the product.
3. Please wash the drum with clean water, wipe it clean before using.
4. Please wait till system completes the cool-off before the cleaning process. You can clean the drum, the silver collection box, and inner cavity. Remove the chaff with a brush (do not use brush that will melt under high temperature). Do not use solvents other than water to clean the machine。

For detailed cleaning, please refer to the cleaning video.

Because the characteristics of each bean are different, you might encounter this problem if you use the same profile for a certain type of coffee bean, it is recommended that you can adjust your first crack time (longer or shorter) to correct this problem.
