Know before you buy
The USB port allows you to connect the roaster to third-party software on your computer. This enables you to track, record, and save precise roast profiles, which you can then play back for consistent results in future batches.
The Hottop KN-8828B-2K+ is designed for batches between 250g and 300g. This capacity is ideal for home enthusiasts looking to roast enough coffee for a week's worth of brewing.
While the unit features a built-in smoke reduction system, it is still recommended to roast in a well-ventilated area, such as near an open window or under a kitchen range hood. The smoke reduction system helps manage the process, but it does not eliminate all smoke and chaff.
While it is marketed toward advanced roasters, it does offer a fully automatic mode that handles the process for you. However, its true value lies in the manual and programmable controls, so it is best suited for those willing to learn the nuances of roast profiling.
Once the roast is complete, you manually eject the beans into the external cooling tray. The tray uses forced air and an agitation arm to cool the beans rapidly, which is essential for stopping the roasting process exactly when you want.
Regular cleaning of the chaff collector and the drum area is necessary to ensure proper airflow and safety. Because this is a mechanical device, you should also periodically inspect the internal components for any buildup of coffee oils or debris.
Yes, the roaster is designed to offer flexibility. You can start in automatic mode and take over manual control at any point if you want to adjust the temperature or fan speed based on the development of the beans.
