5. Operating Instructions

5.1 Roasting Coffee Beans

The CAFEMASY SCR-300 is designed for optimal roasting of 300g (0.6lb) to 500g (1.1lb) of green coffee beans at one time.

1. Prepare Beans: Ensure green coffee beans are clean and free of debris.
2. Load Roaster: Place the desired amount of green coffee beans (300g-500g) into the non-stick roasting pan. Spread them evenly.
3. Secure Lid: Place the transparent glass lid securely on the roaster.
4. Set Temperature: Turn the temperature control dial to your desired roasting temperature. For a light roast, start around 180°C. For darker roasts, temperatures up to 240°C can be used.
5. Start Roasting: Flip the ON/OFF switch to the "ON" position. The indicator lamp will light up, and the stirring mechanism will begin to rotate.
6. Monitor Roasting: Observe the beans through the transparent lid. You can use an electronic thermometer through one of the lid's airholes to monitor internal temperature without opening the lid.
   • First Crack: Typically occurs around 180°C-200°C, usually within 8-12 minutes, depending on bean type and quantity. You will hear distinct cracking sounds.
   • Second Crack: Occurs at higher temperatures, around 220°C-230°C, usually 3-5 minutes after the first crack. This indicates a darker roast.
7. Stop Roasting: Once the desired roast level is achieved, immediately turn the ON/OFF switch to "OFF" and unplug the unit.
8. Cool Beans: Carefully remove the roasted beans from the hot pan and spread them on a cooling tray or surface to cool rapidly. Rapid cooling prevents over-roasting.
