The ultimate overachiever

Roast better coffee with ROEST P3000. Focus on your day-to-day tasks while the roaster takes care of the rest.

ROEST P3000 is a flexible roaster that’s just as easy to operate with or without previous roasting skills. Enjoy full automation from start to finish.

✓ Intuitive
✓ Responsive
✓ Consistent

The P3000 is a 3kg user-friendly coffee roaster designed for simplicity and precision. It offers full automation, easy maintenance, and consistent results. It’s a robust coffee roaster, making it ideal for demanding production environments — and easy to learn for new coffee roasters.

The P3000 is a reliable tool for coffee roasting, equipped with advanced sensors to ensure predictable roasting results. Its design focuses on even heat distribution for unparalleled consistency between batches. You won’t be able to taste the difference between two batches of the same coffee roasted with the same profile on the P3000. 

The P3000 collects a lot of data during roasting, and we are constantly looking for ways to improve. For coffee roasting, temperature is still the most fundamental parameter to have control over. It’s no secret that we have added a lot of sensors to the P3000. 

Bean temperature
There are two different types of BT sensors. One is super-fast and accurate. The other is stable over time and super accurate. Combining these two sensors, we get the most accurate BT reading possible.  We are adding one of each sensor to each side of our symmetrical roasting chamber and giving the user the average of all four sensors. 

To achieve the accuracy we are looking for we are developing a calibration chamber to calibrate each bean temperature sensor in house. 

Drum temperature
An average of three sensors measures the surface temperature of the roasting chamber drum, located at optimal points along the drum and combining two different types of sensor for the highest accuracy and stability over time.

We can see that the drum temperature stabilizes after an appropriate heat-up or a few batches of coffee. It then follows the coffee roasting process cycle without overheating throughout the day. 

Inlet temperature
Having control of the heat going into the roasting chamber is critical for a precision tool like P3000. For an even heat distribution, we are using three heating elements in a row. These are located outside the roasting 

chamber, with a pre-mixing chamber for the cold incoming air and a pre-mixing chamber for the heated air going into the roasting chamber (through holes in the drum wall). To control the temperature precisely, each heating element has two custom sensors arranged in opposite locations. This grid of six sensors and an optimised PID ensures the inlet temperature follows your profile exactly. 

First crack 
First Crack detection in the P3000 proved a challenge as the roasting chamber has a positive pressure inside. We have overcome this problem, and are fine-tuning the algorithm to work across batch sizes and coffees. Development and deployment of more advanced models has been made possible by our integration of OTA (over the air) updates for the first crack module. 

Camera 
The P3000 integrates a bean camera which displays real-time images of the beans in the drum, replacing a traditional trier. In order to achieve maximum consistency across batches it is essential to remove the destabilising effect of triers on the roasting system. Camera integration is the basis for a suite of future tools to aid decision making, and eventually influence the control system. Colour tracking, the first feature which will be released, gives an indication of the rate of colour change indicative of the velocity of the roast.

As we gear up for the pilot phase and begin planning for production, we remain focused on quality and innovation. Stay tuned for more developments, and thank you for joining us on this journey.
