HB-L3S [G&E] Coffee Roaster

The HB-L3S is a convection coffee roaster available with both gas and electric heating options. It supports a flexible batch size of 1–3 kg, a roasting capacity of up to 12 kg/h, and a typical roasting cycle of 6–15 minutes, meeting the needs of small-batch and continuous coffee roasting operations.

The machine features a cast-steel drum with a customizable double-layer structure and a double-layer multi-piece paddle design. Its adjustable drum speed of 50–70 rpm supports controlled bean movement during roasting. A hot-air fan discharge of 3.9 m³/min and an 80 mm hot-air duct provide stable airflow throughout the roasting process.

After roasting, the stirring cooling system uses a cooling fan discharge of 11.78 m³/min and a 100 mm cooling duct to remove residual heat efficiently. Separate hot-air and cooling ducts help organize the roasting and cooling airflow. The machine also includes a four-way temperature display, air-pressure and gas-pressure monitoring, APP-supported operation, and USB/Wi-Fi data output for convenient process control and roast-data management.
