Neuhaus Neotec Debuts Neoroast Technology
Compact roaster Neoroast by Neuhaus Neotec. Developed for specialty roasters and smaller batch production
Coffee roasters are always looking for new ways to refine their profiles and to optimally adjust strategies to highlight the character of each coffee. This nuance can only take place to the extent that the respective roasting system allows it.
According to Neuhaus Neotec, the greatest restriction in roast profiling is the thermal inertia of the system, which becomes greater the more mass has to be temperature-controlled. Neuhaus Neotec recognized this problem early on and developed a hot-air roasting system called “rotating flexible batch” (RFB), a technology that is more energy efficient and dynamic than typical roasting systems available on the market.
The new Neoroast machine brings this technology to smaller specialty roasters and allows a precise roasting curve design over a wide temperature range. Neoroast is available in two sizes – NR 15 with batch size from 5 up to 15 kg and a capacity up to 120 kg/h and NR 30 with batch size from 10-30 kg and a capacity up to 240 kg/h. Roasting cycles are from 5-20 min.
In contrast to traditional roasting machines, the beans are roasted solely in an air stream that ensures an optimal temperature transfer from the hot air (as the energy source) into the bean over the entire surface. Due to the special chamber design, the beans rotate in a closed circuit in which the product temperature is measured precisely. Precise temperature control allows the roaster to enter the curve at any time during roasting and quickly change the product temperature. Due to the low storage capacity of the system, it is even possible to maintain or reduce the product temperature during the roasting process.
The roaster can decide between manual roasting and full support by PLC control, including step roasting, curve recording, and complete recipe management. The operation is conveniently carried out via a tablet.
