4. Operating Instructions
- Wait until the roaster reaches the desired roasting temperature. Default setting:
220C.
NOTE: For all 2,4 and 6 drum models, switch on the cyclone at this stage.
Always make sure that the cyclone is switched on prior to roasting.
-Pull the airflow knob out to enable air suction through the drum. Recommended
st
setting: initially half open, then fully open after "yellow stage" or "1 cracking" of
beans.
- Fill exactly 100g of beans into the hopper with the filler. Set the heat control
dial to achieve a roasting time between 8-12 minutes. This typically occurs at
dial #5 and #6 but may vary.
- During the roasting process, from time to time use a spoon to sample and
monitor the degree of roasting from the hopper.
- After obtaining the desired result, turn the heat control dial counterclockwise to
shut down the thermal bulbs. Push in the airflow knob to enable air underneath
the cooling trays. To discharge the batch, lift the drum handle of the appropriate
roasting drum up and pull forward. After emptying the roasting drum, move the
handle back gently. In the event that more coffee is being roasted, bring the heat
control dial back to the desired setting.
- Make sure all beans are emptied and repeat the roasting operation as desired.
- Continuously spread the roasted beans evenly by using the supplied spoon.
Ensure proper cooling within 3 minutes. Pour the roasted beans into a coffee
tray.
- Prepare for grinding and cup testing or storage as required
