Automatic roasting
Warning
Automated mode with or without First Crack Detection is meant to be a tool for data gathering and automation. The roaster can never be left alone in automated mode and requires supervision.
Automatic roasting with First Crack Detection (FCD)
When receiving your ROEST, the First Crack Detection is switched off. Before roasting, you must turn it ON to activate it.
ROASTING
Once the machine has reached the target temperature for the selected profile (or waiting temperature when using a Power profile):
1. Add green beans to the hopper and pull the charge handle. Make sure all the beans enter the roasting chamber.
2. When First Crack Detection is ON, beans are roasted from the start until the end without any action needed. Wait for ROEST to release the beans in the cooling tray and let the beans cool down for about 90 seconds. You can start a new roast while the beans are cooling.
You can override the Development Time countdown if you want to release the beans immediately. Tap the Development time countdown area, and the automatic drop is canceled and “DROP NOW” enabled. Tap again to release the beans.

ROASTING
Once the machine has reached the target temperature for the selected profile (or waiting temperature when using a Power profile):
1. Add green beans to the hopper and pull the charge handle. (Make sure all the beans enter the roasting chamber).
2. When you hear cracks, you must manually register the First Crack event: Tap “Next Event: FIRST CRACK”.
Tap “NEXT EVENT” in the upper left corner of the main touchscreen until you see FIRST CRACK.
3. When the development time countdown is over, ROEST releases the beans into the cooling tray. Let the beans cool down for about 90 seconds. Collect the beans or add another round of beans and start roasting while the previous batch is cooling down.
Watch the video below with detailed steps of automatic roasting without First Crack Detector.
From auto to manual and back
When you roast in automatic mode, and you intentionally or by accident adjust a parameter (power or temperature) that turns on manual mode, you can still go back to automatic mode by going to profiles and selecting the profile you are roasting with again.
Manual roasting
Manual roasting is available for Power Profiles and Air Temperature (ET) profiles. We recommend using Power Profiles for manual mode.
Sections:
Important information
• If the air temperature is adjusted while roasting with a Power profile, the profile will turn into a manual ET profile.
• You can use automatic First Crack detection while roasting in manual mode. Even when roasting manually, it will register the First Crack and start the automatic countdown. If you want to perform a fully manual operation, turn First Crack detection off.

PREHEATING
1. Select a power profile, close the drum and wait for the roaster to have reached the waiting temperature.
2. If you want ROEST to automatically register the First Crack, turn on First Crack Detection.
3. You can adjust the waiting temperature if you wish:
Adjusting the waiting temperature
ROASTING
Once the machine has reached the WAITING TEMPERATURE, you are ready to start roasting.
1. Add green beans to the hopper and pull the charge handle.
2. By adjusting the power, you will switch to the Manual PWR profile - tap on POWER and use the rotary knob to change the value.
You are currently in Manual Mode. Read about all parameters available to adjust in the article “Roasting parameters”.
When the First Crack Detection is on, ROEST automatically registers the FC - even when roasting in manual mode.
3. End the roasting process your preferred way. See the three ways how to end a roast here.
4. Collect the beans or add another round of beans and start roasting while the previous batch is cooling down.

PREHEATING
1. Complete the “BEFORE ROASTING-PREHEATING” steps to select an ET profile.
2. If you want ROEST to automatically register the First Crack, turn on First Crack Detection.
ROASTING
Once the machine reaches the targeted temperature, you are ready to roast.
1. Add green beans to the hopper and pull the charge handle. (Make sure all the beans enter the roasting chamber).
2. By adjusting the Air Temperature (ET), you will switch to the Manual ET profile - tap on AIR TEMP and use the rotary knob to change the value.
