Giesen W45 A: Industrial Coffee Roaster from the Netherlands

If you’re running a high-volume coffee roastery and need consistent, high-capacity roasting without sacrificing control, you’ve likely considered an industrial-grade machine. But how do you balance throughput with precision, especially when every batch matters? The answer lies in a proven European platform built specifically for serious production environments.

The Giesen W45 A is a 180 kg/h industrial coffee roaster built in the Netherlands, designed for large-batch specialty roasting with full automation and precise control over every parameter. Its 45 kg batch capacity and rapid cooling make it ideal for high-output roasteries.

What Is the Giesen W45 A?

The Giesen W45 A is an industrial coffee roaster developed by Giesen Coffee Roasters in 2011. With a maximum batch size of 45 kg and an overall production capacity of 180 kg/h, it’s engineered for large-scale specialty roasting operations. Every component—from the drum to the cooling system—is built for durability, efficiency, and repeatable results at volume.

How It Automates the Roast

The Giesen W45 A offers a fully automated roasting process. Green beans are automatically fed from the hopper into the drum. Once roasted, beans discharge into a high-capacity cooling fan that cools a full 45 kg batch in just 3 minutes. While cooling, the system allows loading the next batch—maximizing uptime. The entire sequence, from loading to cooling, is hands-off and optimized for continuous operation.

Control and Customization via Touchscreen

Roast profiles are managed through Giesen’s standardized Roast Profile System, accessible via an intuitive touchscreen control tower. You can program, save, and replay roast profiles for different coffees, adjusting time, temperature, fan speed, drum speed, and even internal drum pressure. This ensures each coffee type is roasted identically to your target profile, batch after batch. Saved profiles make switching between origins or processing methods seamless.

Build and Technical Features

The roaster features a cast iron double-walled drum with high-performance bearings, reducing wear and ensuring even heat distribution. Low-noise fans and an internal cyclone manage chaff collection. Standard finishes include black or silver-grey, with optional RAL color customization. The machine is built for easy cleaning and maintenance. It supports propane, butane, or natural gas, and operates on 3-phase 230V/400V power at 50–60 Hz. Every unit is fully CE-tested and manufactured entirely in the Netherlands.

Additional Options and Controls

Beyond the base model, the W45 A supports full automation, including vacuum or cable-way auto-fill systems. A 60 kg destoner is also available as an option. Automatic airflow and burner controls, along with data logging, add further precision. The machine accommodates any gas or power setup and is built for industrial reliability.
