German industrial roasting systems maker Neuhaus Neotec recently introduced three new industrial hot-air roasting machines under the Gourmet series name.
The three new models are: the Gourmet 1000, which roasts 35 to 110 kilos per batch, and as much as 1,000 kilos (2,204 pounds) per hour; the Gourmet 1500, which roasts 50-150 kilos per batch; and the Gourmet 2000, which handles 70-220 kilos per batch.
Sitting somewhere near the middle of Neuhaus Neotec’s industrial roasting capacity range, all three of the models in the Gourmet line reflect the company’s patented RFB roasting system technology, which involves convective heat transfer and offers customizable options for heat sources, including gas-fired, electrically heated or hydrogen-fueled.
According to Neuhaus Neotec Head of Marketing Lars Henkel, the Gourmet series is based on the company’s well-established RG series, which is now extended by the Gourmet 2000.
“Based on the smallest roaster type, 1000, all three sizes are technically revised, which led to a clear cost reduction due to a higher degree of standardization of the design and equipment,” Henkel told DCN.
As opposed to traditional drum roasters, the Neuhaus Neotec machines use hot air to roast the beans, with no moving elements within the roasting chamber. Light particles, such as chaff, are separated by airflow and discharged into the cyclone without barriers. Given the light touch promised by the hot air roasters, Neuhaus Neotec is promoting them not only for coffee, but also for seed or nut roasting applications.

“As a pioneer of hot air roasting, the new Gourmet once again demonstrates the wide range of possibilities that this roasting technique offers, not only in the coffee sector,” Neuhaus Neotec General Manager Ralf Torenz said in a statement from the company. “The incredible flexibility of the process offers such far-reaching possibilities for product refinement that we can now also reach customers with the new generation who previously had to resort to other systems due to a lack of alternatives.”
According to Neuhaus Neotec, the roasting and cooling chamber designs allow for fast emptying from one to the other while maintaining heat in the roasting chamber, allowing for fast turnaround between batches and reducing stress on materials.
Operators of the machines use a large touch panel featuring live process visualization and recipe management, with up to 21 profiles stored. The systems include programmable logic controllers (PLCs) — computer systems used to manage and simplify large industrial processes — designed to maximize profile management capabilities while ensuring homogenous results among different batches.
With coffee roasting and processing installations throughout the world, and a particular emphasis on the Europe, United States and Asia markets, Neuhaus Neotec is part of the Kahl Holdings group of industrial equipment companies.
The company, based outside of Bremen, counts Jacobs Douwe Egberts, Nestlé, Tchibo, Kraft Heinz Foods, Aldi and MZB Segafredo among its past and/or current clients.
In February 2024, Neuhaus Neotec installed what it described as the world’s first 100% electric industrial-scale roaster in Canada.
