Commercial Coffee Roasters (5 to 30 kg Batch Capacity)
Engineered for specialty roasteries, wholesale coffee suppliers, and multi-location café groups roasting 50 to 3,500+ kg weekly. Heavy composite double-wall drums, low-NOx modulated gas burners, and native Cropster/Artisan telemetry.
CAST Series Commercial Lineup
RC CAST-5: 1.5–5.5 kg batch capacity (20 kg/h output). Ideal for boutique cafés and specialty micro-roasteries requiring agility with 220V power and low gas footprint.
RC CAST-15: 6–16 kg batch capacity (60 kg/h output). The benchmark wholesale commercial machine for single-shift wholesale roasting operations.
RC CAST-30: 12–32 kg batch capacity (120 kg/h output). Heavy commercial workhorse delivering up to 1 ton daily for large roasteries and multi-branch chains.
Core Commercial Engineering Pillars
Double-Wall Cast Iron Drum: 12mm thermal air gap shields coffee beans from direct burner flame conduction, eliminating scorching while promoting sweet convective heat transfer.
Low-NOx Premix Burner: Micro-modulated atmospheric premix gas burners with 0.1% resolution, delivering clean combustion, high turndown ratios, and instant thermal response.
Independent Dual Blowers: Dedicated roast exhaust fan and cooling tray blower operate simultaneously with zero vacuum suction interference, cooling batches to ambient in under 3 minutes.
Cropster & Artisan Ready: Native RS-485 Modbus RTU interface with high-response PT100 thermocouples for bean temperature (BT) and environmental temperature (ET).
Direct Factory Support: 18-month comprehensive factory warranty and 10-year guaranteed spare parts dispatch directly from RC-Tech headquarters.
