Roasters
The innovative Neuhaus Neotec roasting plants have set milestones in the market. Unparalleled opportunities for the creation of traditional and innovative roasting profiles are the basis to meet all demands on quality and quantity.
Also flexibility, high availability, consistency, ease of operation, ease of access and low energy consumption are features which are implemented in all of our roasters. We are proud of our leading role when it comes to top performances. Decades of know-how and common development with our customers will ensure that our customers are always one step ahead.
With our unique RFB roasting process as well as our RG and drum roasters we offer our customers a wide range of high-capacity roasters.
All market needs, from the espresso, the conventional and fast roasting to special roasting requirements such as for capsules are covered by our machines.

More flavour
Our processes allow roasting at low temperatures which are gentle to the bean:
without mechanical treatment by means of beating tools,
the whole bean receives uniform heat without agitating and beating tools being involved,
the temperature level is efficiently adapted to the bean development by means of profile roasting,
this is achieved without the insulating effect of the drum insulation,
the instant cooling in a specially developed cooling process is unique.
This special cooling process ensures "freezing/fixing" of the sensitive flavours in the beans. Thus uncontrolled post-roasting of the beans which takes place in other systems is avoided.
Energy-saving roasting
The energy consumption is one of the lowest on the market. This has always been one of the primary aims of our development work. The following measures have been implemented and optimised in our roasters to achieve this aim:
optimum heat transmission and air ducting
low roasting temperature
no water quenching in the roaster required
very low percentage of exhaust air compared to other systems
Additionally, we can recover energy by means of pre-heating the coffee batch and the combustion air.
More knowledge by know-how
Our roaster developments have set new standards. Many of our long-standing standards are announced as innovations in advertisements by our competitors, today. Among them criteria such as: flexibility, consistency, ease of operation, easy access, high availability, low energy consumption, high degree of recirculation.
We are proud of our leading role in first class performances. Our decade-long know-how and joint development work with our customers will help our customers to always be one step ahead.
Our roaster know-how team includes specialists of different fields, such as design engineers, process engineers, software specialists, and coffee tasters. Our deep understanding of the coffee technology is based on decades of experience of the teams involved, it being understood that the top priority is the close cooperation with our customers.
Neuhaus Neotec owes its standing to custom-made solutions and overall concepts. We share our know-how: Our in-house training centre offers seminars on current topics from the world of coffee.
Higher quality
Our technology provides competitive advantages for you as a roaster.
Which are the market requirements?
How is the cup to be achieved?
What is the blend like?
Development of body, pleasant acid, aroma perfection?
Reproducible, consistent roastings which are independent of moisture and temperature from the first batch?
Rapid change of roasting conditions?
We have developed this flexibility for you. Optimum roasting from the first batch.
More roasting profiles
Profile roasting is a generally known, common method to adapt the roasting conditions to the bean development in the course of the roasting process.
This is a standard feature of all our roasting machines. Today, the operator can choose between copy roasting, profile roasting and step roasting. The low specific heat capacity of the system is an important factor. It enables the control parameters to act on the bean.
By means of the Neuhaus Neotec profile control, the bean temperature and all the other parameters of the recipe are monitored until the end of the roasting process.

More innovative solutions
Neuhaus Neotec have developed the so-called Rotational Flexible Batch process. Even today, this is a unique process. It means uniform roasting without conventional mixing and beating tools. The air quantities and the temperature level can be modified within a wide range.
Higher availability
Our roasting machines provide the highest availability compared to other systems on the market.
Some of the reasons are:
Our innovative technology without mechanically movable parts and thus reduced wear
no water injection in the roasting section like in other processes, which avoids wear.
By means of the patented air flow, the "intermediate roasting", the beans are uniformly moved and heated. See also our video on:
RFB
RFB Batch Roaster - Rotational Flexible Batch
Our innovative RFB batch roaster is the machine with the broadest range of roasting profiles, possibilities and qualities on the market. The RFB provides every possibility to get the best out of the bean and to preserve it. In the capacity range from 500 kg/h to 5,000 kg/h (with pre-heating), custom solutions are available for
- main stream and fast roasting
- main stream and slow roasting
- slow and extremely dark roasting
- pre-heating by means of fresh or process air
- recirculation or open system
- thermal or catalytic exhaust air cleaning
- profile, step or copy roasting
Additionally, there are the concept-related advantages: no moving parts in the roaster, unique bean temperature measurement directly in the roasting chamber, no water in the roasting chamber required, unique safety concept, no post-roasting by rapid cooling.
The RFB thus offers an unrivalled production flexibility due to the rapid implementation of the roasting parameters and the simple recipe control.
RG - Roaster Gourmet
Developed from the successful RFB series, the RG has been designed for roasting of specialities in smaller capacity ranges of up to 1,500 kg/h.
Especially in the slow and espresso roasting, it offers within its range of capacities maximum flexibility in the selection of parameters (roasting time, roasting temperature). Even small batches can be roasted precisely. A powerful cooling system ensures the preservation of the aroma and prevents uncontrolled post-roasting. The roasting and cooling process can be monitored continuously.
