Norwegian roasting equipment manufacturer Roest (formerly Røst) is rolling out the L100 variant of its AI-driven hybrid sample roaster. At the same time, the company is readying its next big release, a 2 kilo electric commercial coffee roaster called the P2000.

Roest will be exhibiting the L100 at the Specialty Coffee Expo in Boston this week (booth #331), where representatives will also share information about the upcoming P2000 roaster.

Roest L100 Sample Roaster

The electrically powered Roest L100 comes to market with black panels as opposed to the white panels of a 2020 pilot version or the wooden panels of the original Roest model, the S100.

Handles made of PTFE polymer provide durability and heat resistance. The L100 includes the same environmental and grain temperature sensors as the S100, while adding new drum and exhaust temperature sensors.

Two additional slots are available on the L100 for additional sensors, including a K-type sensor and a PT100-type sensor, for a potential total of six sensors that can be installed upon customer request.

“The combination of the design and multiple sensors makes the sample roasters ideal for research purposes and also for coffee companies with advanced requirements,” Veronika Galova Bolduc, marketing manager at Roest, told the Daily Coffee. News. “The more accurate coffee data we can provide during roasting, the better it is for consistency and, more importantly, for new insights we can gain from it.”

Reinforced stirring paddles inside the L100’s drum are three times stronger than those of the S100, while a proximity sensor on the L100 alerts users to beans waiting to be removed from the tray cooling.

“When you have a fully automated coffee roaster, you might find yourself overly focused on the other important tasks of your job,” Bolduc said, “so it’s really helpful when the machine tells you that you need to remove the coffee from the coffee tray. cooling to avoid two batches mixing together in one tray.

Featuring a hybrid drum and hot air roasting system similar to what is found in other Roest machines, the larger P2000 is designed to roast batches of 1 to 2 kilograms (2.2 to 4. 4 books).

The machine weighs approximately 60 kilos (132 pounds) while operating on 3,500 to 5,500 watts (1 or 3 phase). While sample roasters draw hot air through openings at each end of the drum, the P2000 pushes air through the entire bean mass, which Roest says increases roasting energy efficiency. larger batches while allowing faster roasting and lower temperatures.

The heating elements at each end of the P2000 roasting chamber are monitored by a dedicated temperature sensor which corresponds to a bean temperature sensor (BT) and an ambient temperature sensor (ET). The automated system is designed to maintain and adjust temperatures precisely and evenly.

The machine will also have the first sample roaster crack detection function as well as color tracking function, chaff compression system, housing design promoting ease of maintenance and more features, according to the society.

“Our final prototype is currently in production,” Roest CTO, co-founder and product developer Sverre Simonsen told Daily Coffee News. “We aim to have a small number of roasters ready for assembly and testing after the summer, and these will go to our first ‘pilot’ customers… Unfortunately the new prototype will not be ready for the SCA Expo in Boston but we are confident to bring the final model to the United States next year, which will be ready for purchase.

Simonsen said the estimated price for a P2000 would start at $16,000. The Roest L100 is available now in configurations ranging from $7,200 to $7,850 (excluding VAT).
