Learn how to roast on a Hottop

Home roasters rejoice! The Hottop KN-8828B-2K+ is here and has raised the bar for quality home roasting. The 2K+ now offers users even more control than its predecessor, the KN-8828P-2K, allowing total roast time, target roasting temperature, fan speed, and heating power to be controlled manually - even in the middle of a roast. The possibilities presented through these variables are virtually endless, which means users can make fine adjustments to hone in on the ideal parameters. The 2K+ features two K thermocouples and real-time monitoring over both bean temperature and environmental temperature. Both temperatures, along with all other roasting data, are displayed on a new high contrast LED screen throughout the roast cycle . A bi-directional USB port supports third party software for real-time monitoring and graphing of roasts as well as computer control of the roaster (software can be found here).

  • Advanced LED screen with wide viewing angle, high contrast, and full roast data displayed in real time
