Commercial Coffee Roasting Machine 3 Kg Capacity

Q: What roast capacity does a 3 kg batch machine provide per day?

A: A 3 kg batch roasts in 12–18 minutes. With 10-minute cooling between batches, operators complete 15–20 batches per 8-hour shift. Daily output reaches 45–60 kg of roasted coffee depending on workflow efficiency.

Q: Does the machine require dedicated electrical supply?

A: The 1.24 kW heating element operates on 110 V, 220 V, or 230 V single-phase supply. Confirm voltage at time of order. A dedicated 15-amp circuit prevents voltage drop during roasting cycles.

Q: How is roast progression monitored during operation?

A: Sight glass on drum face permits visual monitoring of bean colour. Operators listen for first and second crack audible cues. Optional probe thermometer measures bean mass temperature if specified at time of order.

Q: What maintenance schedule does the roaster require?

A: Empty chaff collector after each roast cycle. Clean drum interior and cooling tray weekly to remove residual oils. Inspect drive belt tension and heating element monthly. Replace thermocouples annually or when temperature readings drift.

Q: Can the machine roast different bean origins consecutively?

A: Yes. Cool drum to below 60°C between batches to prevent carryover heat affecting next roast profile. Clean chaff collector between origins to avoid flavour cross-contamination from shed bean skin.
