How it works
Indirect hot air + vortex drum agitation
The CBR-301 circulates heated air through a rotating glass chamber while the off-axis “vortex twisting” motion continuously mixes the beans.
This helps promote even roasting, and the chaff drawer collects husk for easier cleaning.

Step-by-step
Your first roast
-
- Weigh 200–250 g of washed beans for your first batch (you can move up to 300 g once you’re comfortable).
- Insert the roast chamber and make sure the chaff tray is empty. Connect the vent pipe if you’re using external venting.
- Set Time 15:00 and Temp 450°F (232°C); press Start. (No preheat needed.)
- At yellowing (often ~4–6 min), raise temperature if needed (e.g., 470–500°F) to maintain steady momentum.
- Listen for first crack (commonly ~9–12 min). For lighter roasts, reduce heat slightly and develop 60–120 s.
- Hit Cool at your target. Let the automatic cooling finish, then empty the chaff tray and allow the roaster to fully cool.

CBR-301 Roast Curve
(Light • Medium • Dark)
The vertical axis shows set temperature (°F) — a helpful reference for repeating profiles.
Values are approximate and vary with batch size, ambient conditions, and voltage.
Light (City)
Dry end
First crack
Target
Light: stop ~60–120 s after first crack. Use set temp as a guide.
Medium (City+ / Full City)
Dry end
First crack
Target
Medium: finish ~90–180 s after first crack; keep momentum steady and avoid stalling.
Dark (Full City+)
Dry end
First crack
Target
Dark: finish ~180–270 s after first crack; vent well and watch smoke.
Note: temperatures are set-temp references (not internal bean temp). Use them as guidance and prioritize color, sound, and aroma.

FAQs
How much can I roast per batch?
The CBR-301 roasts from 100 g up to 300 g. Start at 200–250 g until you learn the machine.
Do I need ventilation?
Yes — especially for medium-dark roasts. Use a range hood, open window, or a vent pipe to the outside.
What makes it different?
Vortex twisting (off-axis rotation) and indirect hot air help roast evenly, with an optional Bluetooth app for profile saving.
Is preheating required?
No — the roaster is designed to warm up gradually. Improper warm-up can reduce durability.
