1. Close the drum to preheat (drop handle in downward position)

2. Select profile: tap on timer -> Select Profiles

3. Charge beans to start roasting

4. Register first crack

5. Bean drops automatically after the set development time

6. Open the drum to cool down the machine, or keep it closed to continue roasting

Preheating

These steps apply whether you roast in automatic or manual mode.

1. Turn ON the roaster.

Switch on the back of the roaster

2.a. Connect to Wi-Fi. Read how to do it here. If you wish to download new profiles, watch live view on Web Portal or store roasting logs, you must be connected.

(Skip step 2.a. if you are using ROEST without Wi-Fi).

2.b. PREHEATING: Close the drum by moving the drop handle to the downward position.

Drum closed - Handle down

3. Select a profile.

1. Go to the Main Menu

2. Tap “PROFILES”

3. Choose a profile

The roaster will start preheating to reach the target temperature of the chosen profile. The roaster is ready for roasting once it has reached the target, which will take a few minutes.

To learn more about roasting profiles, read here.

Start roasting

When the drum has preheated to the target temperature:

1. Add green beans in the hopper and pull the charge handle (make sure all the beans enter the roasting chamber).

2. The roasting process has started.

During roasting

The automatic mode is set by default on your roaster. However, you are always free to change to manual roasting:

1. Adjust power or air temperature while roasting to switch to manual mode.

2. When you hear the cracks, tap the “First Crack” button (unless your roaster has a First Crack Detection system).

ROASTING EVENTS

Read here to learn about the three types of events you can register while roasting.

End roast

There are three ways of ending the roasting process in both automatic and manual mode:

1. After the development time countdown is over, ROEST automatically drops the beans into the cooling tray.

2. Cancel the development time countdown, as shown below:

Tap on PRESS TO CANCEL DROP

Tap on DROP NOW when you are ready to drop the beans

The beans will drop inmediatly

3. Manually open the drum by moving the drop handle to the upward position. If you want to do another roast, close the drum again.

Drum open - Handle up

OPEN drum

CLOSED drum

You can start a new roasting process while the beans are cooling down, with the same profile, or by selecting a new one.

IF YOU’RE DONE ROASTING: cool down the roaster and turn it off.

1. Open the drum by moving the drop handle to the left upward position.

2. Wait for the temperature to cool down to about 45 degrees Celsius.

3. Turn off the roaster.

4. Empty the chaff drawer (Note: remember to reset the chaff counter next time you turn on the roaster).

5. Pull out the charge handle from the roaster and check for any beans stuck in the exhaust. If you regularly find beans here, you may need to reduce your RPM or exhaust fan settings, especially at larger batch sizes.
