Modular roasters feature an external heat generation unit which allows superior productivity and layout flexibility. This model can roast up to 720 kg per cycle and include an innovative energy-saving system.
TMR Series are modular drum roasters suitable for a wide range of coffee roasting profiles, with a capacity to roast from 1000 to 3600 kilograms per hour. TMR Series have been specially designed for industrial productions that require high profitability and repeatability of the roasting processes during the various working stages.
TMR model roaster is the first drum roasting machine engineered with the roasting air Recirculation and Heat Recovery System. The TMR’s system uses just one burner as a heat generator and after burner to reduce carbon emissions, saving, on average, 35 to 40 per cent more energy compared to traditional roasters.
TMR roasting process ensures consistent degree of roast and roasting time, in order to reach the best bean quality consistency, despite of any affecting external conditions like production start-stop-restart, green coffee quality, coffee moisture, change of coffee lot. This is the reason why TMR is suitable for frequent recipe changes with a guaranteed repeatability and gives the possibility to create innovative roasting profiles for new flavour characteristics and physical bean properties.
The roasting profiles are previously designed on ORCHESTRA, the TMR’s control system, by setting the time and bean temperature as independent variables, thus allowing to keep a consistent quality of the product right from the first batch up to the last roasting cycle, achieving the desired roasting profile in terms of time, color and flavor.
Low energy consumption and reduced NOX, VOC and CO emissions by using a unique heat generator that acts both as burner and thermal afterburner.
ORCHESTRA is the integrated management and control system of the TMR Series.
TIME-TEMPERATURE LOGIC
In addition to the traditional control systems, ORCHESTRA allows you to pre-set roasting profiles according to a time-temperature logic, also controlling time as an independent variable of the process. It is thus possible to maintain full control of the different roasting phases, determining the final characteristics of the coffee from the beginning.
It is the answer to the need to obtain constant roasting results over time, especially for products such as pods and capsules, eliminating external influences like
the humidity of green coffee, the quantity of the batch entering the roaster, and environmental variables. ORCHESTRA enables full personalisation of the recipes by previously designing the roasting profiles and by setting the time and bean temperature as independent variables.
During the setting of the various setpoints, ORCHESTRA shows a simulation of the roasting profile and the ending time estimated. During the process, the preset profile and the curve in progress will overlap in the visualisation of the roasting trend, thanks to the precise self-tuning of the machine’s process parameters.
These features guarantee exactly the same final color, moisture and taste, day by day, during production.
IMA Petroncini’s steps toward sustainability are more and obvious direct and strictly related to IMA LOW (Low Impact Program) in increasing IMA’s sustainable practices to preserve resources, reduce emissions and develop innovative low impact technologies.
IMA’s sustainable practices are made apparent in the TMR model. During the thermodynamic cycle, the burner acts also as an afterburner so that the roasting air is cleaned up at high temperatures before going again into the drum. In the same time the exausted air is convejed ouside already cleaned. This allows TMR to be able to respect the local restrictions in matter of exausted gas and reducing NOX, VOC and CO emissions, even in the most demanding limits.
Furtermore, the control system ORCHESTRA is a real partner for the energy saving due to the automatic adjustment of all the roasting parameters for the optimisation of the entire process, with the result of significantly reducing the Carbon Footprint. In this way, TMR roasting technology enables, on average, 35-40 per cent energy saving compared to traditional roasters.

The beans coming from different silo cells are mixed and then sent to the packaging lines for coffee bean bag preparation or to the grinders to be ground.
Petroncini provides two types of blending machines combined with a batch-weighing system. The traditional solution is the horizontal mixer with rotating drum, equipped with helicoidal paths moving the product back and forth to perfectly mix the beans. A more advanced solution is a batch auto-cleaning blender suitable for companies that sell roasted coffee beans in bags or for specific hygiene requirements. In this case, the suction system combined with special mechanical components inside the mixer means small pieces of coffee can be removed from the blended product.
