HB-M12S [G&E] Coffee Roaster

The HB-M12S is a compact convection coffee roaster designed for sample roasting, roast-profile development, specialty coffee shops, and small-batch production. It supports a flexible batch size of 0.2–1.2 kg, a roasting capacity of up to 4.8 kg/h, and a typical roasting cycle of 6–15 minutes.

The machine is available with gas and electric heating options. The gas version supports LPG and natural gas and uses a Venturi-premixed fire-row combustion chamber. The electric version is equipped with a 5000 W multiple-unit heating-wire system and supports customizable 380 V or 220 V power configurations.

A cast-steel drum with a customizable double-layer construction and double-layer multi-piece paddles supports stable bean movement and more consistent heat transfer. The adjustable drum speed of 38–75 rpm allows operators to adapt the roasting process to different batch sizes, coffee origins, and roast profiles.

The HB-M12S provides a hot-air fan discharge of 3.9 m³/min through an 80 mm hot-air duct. Its stirring cooling system delivers a cooling fan discharge of 9.9 m³/min through a 100 mm cooling duct, helping reduce residual heat after roasting.

The machine also includes a four-way temperature display, air-pressure and gas-pressure monitoring, APP-supported operation, and USB/Wi-Fi data output. Separate hot-air and cooling ducts support organized airflow management throughout the roasting and cooling process.
