The HB-L6S and HB-L8S are convection coffee roasters designed for medium-volume commercial roasting. The HB-L6S supports a batch size of 3–6 kg and a roasting capacity of up to 24 kg/h, while the HB-L8S handles 3–8 kg per batch with a roasting capacity of up to 32 kg/h. Both models complete a typical roasting cycle in approximately 6–15 minutes.
The machines feature a double-wall cast-steel drum with a double-layer multi-piece paddle structure. An adjustable drum speed of 10–62 rpm supports controlled bean movement for different batch sizes and roast profiles. Electronically adjustable air pressure, a hot-air fan discharge of 7.2 m³/min, and a 150 mm hot-air duct provide flexible airflow control throughout the roasting process.
An integrated stirring cooling system delivers a cooling airflow of 30 m³/min for rapid post-roast cooling. The series also includes a four-way temperature display, air-pressure and gas-pressure monitoring, separate hot-air and cooling ducts, APP-supported control, and USB/HDMI data output.
