Roasting profiles for Hottop Manual

Before you start your roasting, you always check whether there are no more coffee chaff (chaff) in the drawer and in the roasting drum. Put 250 grams of green coffee next to you. Now you set the roaster in manual mode and select the maximum time and the maximum final temperature. Then start. 

  1. The roaster gives you the signal to throw in the beans at 75 ° C. Let the appliance heat up a bit more for this roasting and add the beans at 102 ° C. Now you turn on your stopwatch.
  2. The roaster himself tries to change the heat supply and the fan, because he follows a pre-programmed curve. But you intervene and leave the heat fully at 100% and the fan at 0. Now you can relax a bit during the first approximately 7 minutes.
  3. At about 160 ° C, you notice how the smoke increases. Now you switch the fan to 25%. But not anymore, because we want to get the first crack quickly for this roasting.
  4. After about 9:30 minutes, the smoke continues to increase and you set the ventilation to 50%, at the same time you take some power out of the heating element and go down to 80%, since you are approaching the first crack.
  5. After about 10:30 minutes and at about 182 ° C in the display, you hear how the first cracking begins. Now you can down with the heating element to 70%.
  6. Half a minute later, at 11:00 and 193 ° C, you go with the heating element down to 50% and with the fan to 75%.
  7. Half a minute later, at 11:30 (about 196%) you go down to 30% heating. Now the first cracking slowly ends.
  8. One minute later, at 12:30 (about 200 ° C) you go with the ventilation up to 100%.
  9. After 13:00 (about 203 ° C in the display) you go with the heating element down to 20%.
  10. Once your degree of roast is reached (or little before), press on Eject and finish the roasting.

To shorten the time between roasts, you can open the roaster during the cooling phase by removing the front cover and lid when inserting the bean.
