First Roast Guide
This guide starts after your device is connected and live temperature is updating. The goal is to finish a roast that you can review later, not to learn every HiBean feature at once.
If device setup is not done yet, start with Connect First Device.
Before You Start
- The device connection is stable, and BT or the main temperature channel keeps updating.
- Ventilation, cooling, bean drop, and power-off handling are ready.
- Batch size is close to a normal range for your roaster.
- You know how to charge, drop, stop heating, and enter cooling.
- If you use a reference curve, prefer same device, similar batch size, and similar roast target.
For preparation-page fields, read Prepare Roasting.
Choose a Reference Curve
For the first manual roast, a reference curve is useful for learning roast rhythm. Use this priority:
- A community profile from the same device.
- A successful same-device roast from yourself or someone you trust.
- A same-device profile with similar batch size and roast target.
If you cannot find the exact same bean, prioritize the same device first. Roasters differ in heat response, airflow, and probe placement; for a first roast, device match usually matters more than bean match.
When choosing a profile, check whether it shows a clear reference curve in manual roasting. If a profile mainly depends on automatic control actions and is not useful as a visual curve, save it for the auto replay stage.
Start Manual Roasting
- On Device, confirm the roaster is connected.
- Tap Start Roasting to open the preparation page.
- Select bean, batch size, and reference profile.
- Choose Manual Roasting.
- Confirm preheat state and start.
- After Charge, compare the live curve with the reference curve.
What to Watch
The first roast does not need to match every point. Focus on three signals.
BT Trend
If BT stays below the reference for a while, the roast is generally slow. If BT stays above the reference for a while, it is generally fast. Ignore short wiggles at first; read the overall rhythm.
RoR Trend
RoR shows whether the temperature rise is pushing too hard or falling too quickly. At this stage, watch whether your control changes move the trend in a steadier direction. You do not need to design complex RoR phases yet.
Key Events
Record at least:
- Turning point after Charge.
- Whether the middle phase is clearly fast or slow.
- Approximate time and BT at First Crack.
- Drop time and drop temperature.
If these points roughly align with the reference, the roast is useful for review.
Review After Drop
Do not only check the final drop temperature. Review by phase:
- Was the early phase generally fast or slow?
- Did the middle phase overshoot or flatten too much?
- Around First Crack, were you earlier or later than the reference?
- Did your heat, fan, or drum changes actually move the trend?
Record:
- Preheat condition.
- Batch size.
- First Crack time.
- Drop time.
- The 1 or 2 control changes that mattered most.
If you can explain why one section ran fast or why another section fell behind, the roast has already taught you something useful.
Judgment Boundaries
BT Reproduction Boundary
BT can help reproduce the broad trend and timing of a roast, but it is not a universal answer across devices and environments. Roaster design, probe position, batch size, and ambient conditions all change how absolute numbers should be read.
RoR Use on the First Roast
Observe RoR first. Use it more actively after you can already judge how BT moves against a reference curve.
Auto Replay Timing
Use auto replay after you have completed a few manual roasts and understand the relationship between the reference curve, control actions, and key events. Auto replay is for reproducing existing records; it is not a replacement for the basic observations in your first roast.

Device differences still matter. Preheat behavior, heat response, airflow effect, and probe placement all affect the curve. For device-specific notes, open the matching page in Hardware Support.
