Know before you buy
The Hottop KN-8828B-2K+ is designed for a capacity of 250 grams of green coffee per roast, which typically yields about 200 to 220 grams of roasted beans.
This model is designed for enthusiasts who want control. You can manually adjust time, temperature, fan speed, and heating power throughout the roast, or save your preferred settings into one of the three user profiles for consistent results.
No, the roaster is fully functional using the built-in LCD control panel. The USB port is an optional feature that allows you to connect to a computer for advanced data logging and external roast profile control.
The roaster includes a two-stage air filter designed to reduce smoke particulates during the roasting process. While it helps significantly, you should still operate the machine in a well-ventilated area or near an exhaust source.
The dual thermocouples provide precise monitoring of both the bean temperature and the environmental temperature inside the drum. This data is essential for making informed adjustments during the roast to ensure consistent flavor development.
The Hottop features a manual bean ejection knob that allows you to safely and quickly empty the drum in an emergency. Additionally, the forced-air cooling tray ensures the beans are chilled rapidly once they are ejected to prevent over-roasting.
