Neuhaus Neotec is deeply rooted in the US market and advanced coffee roasting methods that severely impact the coffee industry.
When Gustav Lührs, former general manager of Neuhaus Neotec, was looking for the most advanced roasting solution in the United States, he was approached by chemical engineer and coffee industry consultant Michael Sievetz, inventor of liquid air roasting.
“Based on this idea of roasting, Lührs and his team developed the Rotary Flexible Batch
(RFB) and thus began the journey to a more advanced roasting system,” says Lars Henkel, Head of Marketing at Neuhaus Neotec.
Henkel says the former director of Neuhaus Neotec has a very close relationship with the United States, having established the roasting method for RFB technology in the country.
Neuhaus Neotec RFB roasters allow the coffee beans to be stirred only by the airflow in the chamber, and the heat energy of the roasting air is transferred homogeneously and directly to the beans.
“RFB hot air roasters meet the demands of the growing range of coffee on the market like no other. Gas heated RFB roasting systems are available in different versions depending on the roasting capacity, from 30kg batches to 450kg batches with a roasting capacity up to 4500kg per hour. ‘,” says Henkel.
With this capacity range, Neuhaus Neotec meets the demand for industrial roasters with large volumes of roasted coffee as well as the needs of smaller specialty coffee roasters in smaller quantities but the higher requirements for quality in the roasting process and maximum flexibility in roasting coils.
Moreover, RFB roasting technology shows its full advantages when it comes to flexibility, control over roasting coils and power consumption. The direct transfer of heat from the hot air to the beans resulted in shorter system response times, thus allowing for maximum flexibility in roasting curve design.
Over the past few years, Neuhaus Neotec in collaboration with a leading roasting company has developed an additional patented feature that extends profiles to uncommon curves and maximizes control over the formation of unwanted acrylamide during roasting.
“Chemical components in coffee are being brought more into focus and increasingly regulated by authorities, and this new feature called Triple-A is of great importance in the coffee industry,” says Henkel.
In order to pursue the requirements for minimum energy consumption, Neuhaus Neotec has also optimized its main energy consumption, with burners with a high modulation range, closed and leak-free circulation of hot gas, and exhaust cleaning systems with minimal demand for additional thermal energy for chemical reactions.
Today, Henkel says the RFB is the most energy-efficient toaster in its class, roasting up to 4,500 kg per hour. Exhaust gas cleaning has also become less energy-intensive thanks to new exhaust cleaning technologies adapted to the RFB roasting system.
“Neuhaus Neotec is proud to supply a large American roaster with RFB technology combined with preheating and Regenerative Thermal Oxidation (RTO) for exhaust processing, significantly reducing overall energy consumption in the multi-digit range,” says Henkel.
In addition, for catalytic cleaning systems, the reaction temperature can be reduced to a lower temperature level, which means savings in gas consumption.
“In many large roasters, RFB roasters have become part of standard equipment for a variety of coffee products, from specialty roasting to instant coffee production,” Henkel says.
He adds that another long-term US customer who has relied on RFB technology for many years has just ordered an upgrade of their existing hardware.
Ralph Torrens, Director of the Coffee Division and President of Neuhaus Neotec USA, sees this as a huge sign of confidence in the collaboration, but also in the future direction of the technology.
Henkel says Ralph Torrens is responsible for sales activities in the United States and has a close relationship with the company’s overseas clients.
“He feels a great connection to American society and sees the US as a country with a strong coffee culture. From the start, US customers have been open to new roasting technologies, which was one of the reasons why RFB technology was also able to achieve initial success in the US market so early on. , he says.
The topic of alternative energies is still prevalent in the production industry not only in the United States and Europe but throughout the world, noting that the current price development of fossil energies also contributes to ideas about new technologies.
Neuhaus Neotec is addressing this challenge with its latest development and the soon-to-be-launched electric toaster, which will be launched for the first time in America.
Henkel says that the company’s entry into the development of the roaster began in the Americas and it is likely to see a big leap coming there.
“Because of this special relationship with the American roasting industry, a presence in the American market has always been so important to the heart, and this led to the company’s first expansion with its own office and service team in Atlanta,” says Henkel.
“The US is a diverse country, and different parts of the country are looking for different things. The market is also changing very quickly, so what you need to offer today is flexibility.”
For roaster operators, this flexibility is reflected in the opportunity to do short or long roasts, light or dark, all with energy-saving options.
While the company’s entry into the development of the roaster may have begun in the United States, the German manufacturer has now established itself as one of the world’s largest suppliers of manufacturing equipment for coffee handling and roasting.
“Since its inception, Neuhaus Neotec has continuously developed various roasting technologies and provides some of the most efficient roasting machines on the market,” says Henkel.
“Whether in roasting, grinding or all-processing, we are constantly developing new solutions in order to improve operations for our customers. Our goal is to get the best results across all steps of the process.”
