HB-M2S [G&E] Coffee Roaster

The HB-M2S is a compact convection coffee roaster designed for sample roasting, roast-profile testing, training, and small-batch specialty coffee production. It supports a batch size of 100–300 g, a roasting capacity of up to 1.2 kg/h, and a typical roasting time of 6–15 minutes.

The machine is available with gas or electric heating. The gas version supports LPG and natural gas and uses a Venturi-premixed fire-row combustion chamber. The electric version is equipped with a 1600 W carbon-fiber heating tube, providing a practical heating option for indoor roasting environments.

A cast-steel drum with a customizable double-layer construction and a double-layer multi-piece paddle design supports consistent bean movement during roasting. The drum speed can be adjusted from 30–83 rpm to accommodate different batch sizes, coffee varieties, and roast-profile requirements.

The HB-M2S provides a hot-air fan discharge of 1.9 m³/min and uses an 80 mm hot-air duct. After roasting, its air-cooling system delivers a cooling fan discharge of 1.4 m³/min to help remove residual heat from the roasted beans.

The machine also includes a three-way temperature display, air-pressure and gas-pressure monitoring, APP-supported operation, and USB/Wi-Fi data output. Its compact dimensions and 37 kg net weight make it suitable for coffee laboratories, roasting studios, training centers, and specialty coffee shops.
