  • Page 8: Coffee Roasting- A Brief History

    II - Coffee Roasting- A Brief History It wasn’t that long ago that it was common for people to buy raw coffee beans from the stores and then roast these at home for fresh coffee. That was particularly true in rural areas that were removed from the small roasters found in city neighborhoods.

  • Page 9: Introduction To The Roasting Process

    III - Introduction to the Roasting Process The changes that the coffee bean goes through during the roasting process are amazing. Those small, hard beans, when properly exposed to controlled heat, grow in size and change in color, becoming the source of one of the world’s most cherished beverages.

  • Page 10: Timing Of The Cracks

    • The voltage in your home (it can vary as much as 12-15 volts from place to place) For the KN-8828, use a stopwatch and begin timing from when you pour the beans into the machine. For the KN-8828D and KN-8828P in its “Auto” mode, use the time displayed on the digital readout as a countdown timer.

  • Page 11: Bean Color As A Roast Indicator

    *1 KN-8828 - These times are taken using a stopwatch, starting from when the beans were added to the roaster. *2 KN-8828D - Starting with 19 minutes programmed time on the machine, these are the times as indicated on the digital display as the machine counts down the roasting time.

  • Page 12: Basic Operation Of The Hottop Coffee Roaster

    For your first experimental batch select a variety that is easy to roast. Most any of the varieties from Central or South America will do fine. Guatemalan, Colombian, Brazilian, Bolivian, or Costa Rican are all good choices. These coffees have very loud cracks that are easy to recognize. Moreover, these are also rela- tively inexpensive, so if anything goes wrong, you don’t have to feel too bad about discarding the beans.

    SEGMENT TEMPERATURE The temperature range for each segment which is available for programming varies, from lowest in the early segments to highest in later segments. This is reflected in the “stair step” appearance of the temperature bars in the LCD display. During the roast, each segment dynamically displays its progress of the temperature: The upper portion of each Segment display where the black bars are located represents the range of programmed temperature this way:...

    Advanced Manual Control For those looking for a more precise control over their roasts there are methods that can be used to modify the roast profile while the coffee is roasting. This procedure will take a bit of practice and experi- ence because you will need to predict the end of first crack, but with time this method can help achieve superior results.

  • Page 32: Cleaning And Care (All Models)

    VIII - Cleaning and care (all models) Roasting coffee can be a bit messy. The chaff that comes off the beans, bits and pieces of coffee beans, and stray beans themselves can get strewn about, in and out of the roaster. To create the best coffee possible, to ensure safe operation, and to extend the life of your Hottop Coffee Roaster, it is very important to do some regular maintenance and cleaning.

The coffee usually acquires a similar sharp taste, with the flavor being predomi- nantly “roast” and less that of “coffee.” Some people do enjoy this “French” style but if you are purchasing quality beans this level of roast removes a lot of the taste that you paid for.

    KN-8828P, program more time into the KN-8828D or KN-8828P in AUTO mode, or use a higher roast number on the KN-8828). You can also reduce the batch size to 225 grams of beans. If, on the other hand, the roasted coffee comes out too dark, try increasing the batch size to 270 grams or decreasing the roast time.

  • Page 40: Bean Cleaning

    Roasting decaffeinated coffee is more difficult than roasting “regular” coffee. The decaffeination process makes the color of the beans more difficult to discern and the cracks occur in much reduced num- bers. For this reason, we highly recommend learning to roast with “regular” coffee before attempting to roast decaf.

    as these “low tech” methods allow you to control the brewing temperature and can actually make better coffee than most drip machines. If the coffee is too bitter many people will reduce the amount of coffee they use per cup. That is the opposite of what you need to do.
