Besca manufactures gas-fired drum roasters from their base in Nanjing, China, established in 2014. their lineup runs from 500g sample roasters to 240kg production machines, all built around the same modulated premix burner system and double-wall drum design. the smaller shop machines (BSC-1 through BSC-6) use manual flame and airflow control with profile logging through USB connections to Cropster or Artisan. larger models offer full automation with touchscreen control. build quality leans toward heavy construction and high thermal mass, which several Japanese roasters have noted in public feedback. the company positions itself in the mid-market space: more substantial than entry-level Chinese machines, less expensive than European equivalents. suitable for roasters who want manual control with data logging capability and don't need factory automation. the premix burner system provides fine flame modulation across the range. cooling times are quick relative to batch size. gas consumption specs are published and reasonable. they've gained traction in Middle East and Asian markets over the past few years.
all BSC shop models include USB connections for Cropster and Artisan. the base manual versions log profiles through these third-party platforms rather than proprietary software. higher-tier models with touchscreen control can run BescaTech, their own system that handles profile recording and repeat functions, though you can still use external software if you prefer. no subscription fees for basic logging capability, which matters if you're running Artisan on a tight budget.
premix burners mix gas and air before combustion rather than at the flame, giving you finer control over heat application and cleaner exhaust. Besca uses modulated premix across their range, meaning you can adjust flame intensity continuously rather than in steps. this shows up in steadier heat curves and less hunting when you're trying to hold a specific temperature slope. the trade-off is slightly more complex maintenance than atmospheric burners, and you need correct gas pressure (31 mbar for LPG, 21 mbar for natural gas) or the system won't modulate properly.
published minimums are 0.2kg for the BSC-1, 0.5kg for the BSC-2 and BSC-3, and 1kg for the BSC-6. maximums are 1kg, 2kg, 3kg, and 6kg respectively. those minimums are real limits, not suggestions: the thermal mass of the double-wall drum needs enough bean mass to stabilize. for best control, most roasters work in the middle to upper third of the capacity range. the BSC-3 works well from 1.5kg to 3kg. pushing minimum batches gives you erratic development and less repeatability.
