  • Page 8: Ii - 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: Iii - 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-8828B and KN-8828P in its “Auto” mode, use the time displayed on the digital readout as a countdown timer. Watch those times and compare them to the times in this chart and the description of the roasting process.

  • Page 11: Temperature As A Roast Indicator

    Temperature as a Roast Indicator Temperature is an excellent indicator of the state of the roast. Although the temperature sensor of the Hottop roaster is not in the beans through the entire roast it still supplies useful information that can help you predict changes taking place in the beans.

  • 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.

  • Page 13: Understanding The Lcd Display

    In the Auto mode the user will fi nd that with just three pushes of the START button the coffee roast- ing process will begin. In the manual mode, all parameters of the roasting process can be controlled by the user.

    CONTROL FUNCTIONS To the right of the display are fi ve buttons that control KN-8828B (buttons do not illuminate). MESSAGES At various times a message will appear in the display to alert you: CHAF: The chaff tray needs to be emptied before continuing. Stor - If you choose you may store into non-volatile memory the roast AUTO - The pre-programmed, factory default, automatic roasting mode.

    WARNING: Never leave the roaster unattended during a roast! The KN-8828B gives the user the option to easily and quickly roast using an automatic mode. The “Auto” mode supplies a roasting curve that can begin with as few as three presses of a single button. It can be modifi...

    FIRE SAFETY If at any time the KN-8828P senses that the temperature has reached 414 F, the machine will begin beeping a warning for 30 seconds. If the user takes no action the beans will be ejected and the machine will go into cool down mode.
  • Page 20 WARNING: Never leave the roaster unattended during a roast! The KN-8828P gives the user the option to roast using an automatic mode that operates much like the earlier versions of our roaster. The “Auto” mode supplies a roasting curve that can be set to run for a programmed amount of time and will automatically eject the beans at the end of that time.
  • Page 21 In the display’s Message Center you will now see “Preheat.” The roaster is coming up to temperature. The amount of time this process takes varies. When it is time to add the beans, the machine will beep and the Mes- sage Center will show the “Add Beans”...

  • Page 22: Segment Time

    Although there are eight segments, and each can be three minutes in length, the greatest amount of time for any given Program is 22:00. The KN-8828P will not allow you to save a Program that is greater than 22:00 in total length (not including the Warm-up time which is automatically added to every roast).

  • Page 23: Segment Temperature

    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 refl ected 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:...

Here is how to copy a Program and paste it into another Program slot: Select the Program you wish to duplicate (see Page 24 for instructions on “Selecting a Program”)
  • Page 28 Segment is a way to force the heating element to stay on during that time period. - Because of the amount of time it takes for the KN-8828P to increase the temperature in the roasting chamber, drastic changes should be avoided unless a Program is created that gives suffi cient time for the rise in temperature before time runs out for the Program.

    An alternative to the process described above makes use of the fl exible programming methods of the KN-8828P.

    VII - 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.

    VIII - Roasting styles overview This section contains a brief explanation of the various roasts you can achieve with the Hottop Coffee Roaster, and will give you a general idea of how roast level affects taste. There are numerous factors that affect the roast level at a given time or level setting on the machine.

    a sharp, pungent smell. 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. Roasting even darker, “Spanish”...

  • Page 38: Coffee Varieties And Roast Styles

    For drip coffee, try roasting some quality Colombian and stopping the roast about fifteen to thirty seconds after first crack ends, but before second even starts. This coffee may look lighter than most of what you are accustomed to, but the taste will be a real treat! As time goes along and you become more proficient in your roasting and tasting, you will find that some coffees taste quite good roasted light while others taste better dark.

    vary even if you use the same exact amount of beans, from the same batch of green coffee, and roast at the same exact level. For that reason, we suggest you always carefully monitor your roasts to avoid incorrectly roasted coffee. WARNING: Never leave the roaster unattended during a roast! Central-American, Colombian and African Coffees Although these coffees are very different in flavor, they are commonly very acidic, or “bright”...

  • Page 40: Ix- Tips And Hints

    If the roasted coffee comes out too light try using a longer cycle (Create a longer program for the 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 41: 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.
