THIS IS NOT A COMPLETE MANUAL WARNING! This device is capable of high temperatures. If used without due caution it can constitute a safety hazard. The outer surface will become hot enough to cause very serious burns and the bean roaster has the potential to ignite flammable materials on, in, or near the roaster. The Hottop Coffee Roaster can be operated in such a way as to create a fire hazard by igniting the beans being roasted and/or the chaff (a by-product of the roasting process).

Roast Profiles can be saved for later use as well. Physically, it is the same as our other model. The only difference is the user interface of the control panel.
CONTROL FUNCTIONS To the right of the display are five buttons that control KN-8828B-2K (buttons do not illuminate). POWER - START The largest button at the top of the display controls both “POWER” and “START.” Only one of these two choices will be illuminated in the LCD display at any given time so the button is used for this dual function. EJECT - This is always available during a roast. Use it to immediately stop the roasting process and send the beans into the cooling tray.
RANGE OF CONTROL ADJUSTMENTS Target Time Target Temperature 10:00 to 25:00 167 to 428 F. Main Fan Speed Five speeds. Each of the four bars represent 25%. When no bars are showing the fan is off. Heating Element Power Eleven selectable heating levels. Each bar represents 10% of the heating element’s power. When no bars are selected the heating element is off.

CAUTION: When adding time or increasing the roasting temperature, care must be taken not to burn the beans.
Getting the Most From Your KN-8828B-2K The KN-8828B-2K allows the user to adjust the power of the heating element as well as the speed of the fan throughout the roast. This section is designed to show you how to use this control to more precisely tailor the roast. The information contained in this section will also interest the users of the KN-8828P-2K. Over the years, roasting theories concerning profiles have changed.
The roast used for the graph was done by programming the KN-8828B-2K for maximum time (25:00) and maximum temperature (428 F.). Using these parameters, start the roast as instructed on page 17. Many users have experimented with the temperature at which they add the beans to the roaster. In this roast the beans were dropped in at an the “Beep” signal at a temperature of approximately 167 F. on the display (1), as the red line indicates. You might try waiting until the display shows 200 to 225 F.
Just as you are entering first crack there is a chemical reaction going on in the beans called the Maillard Reaction. Chemical changes in the beans are actually creating heat- the beans are becoming exothermic. The sounds of first crack begins with a sound reminiscent of breaking small wooden sticks. It begins with a few clicks and then increases in frequency. As first crack becomes more active, the heating element should have already been turned down to around 50% (13).
