Neptune 4000. Unrivalled Roasting Capacity
PROBAT has repeatedly revolutionized the coffee industry worldwide with its sophisticated roasting concepts. The manufacturer's drum roaster portfolio includes a particularly wide range of highly diversified roasting machines. They are tailored to individual requirements in terms of efficiency, productivity and product quality and now even cover roasting capacities between 1 and 880 kg – a difference of almost a ton of green coffee.
Following the launch of the innovative NEPTUNE 1000 in 2022, PROBAT is now setting new industry standards in terms of performance, cost-effectiveness, availability, and energy efficiency with the introduction of the world's largest drum roaster, the With the NEPTUNE 4000.
UNRIVALLED ROASTING CAPACITY
With the customer in mind, process optimization, modularization and standardization have been at the forefront of the development of the latest addition to the NEPTUNE range. With batch sizes from 440 to 880 kg and roasting times from 6 to 20 minutes, the NEPTUNE 4000 has an impressive roasting capacity of four tons of green coffee per hour, making it the largest roaster of its kind on the world market. All this adds up to an unrivalled price/performance ratio.
INNOVATIVE HYGIENIC DESIGN
Avoiding contamination of the end product is a key requirement in hygienecritical production environments. The selection of the right materials and the geometric design of the equipment are of paramount importance for clean production processes. In addition to the NEPTUNE 4000's easy-to-clean design, relocated service points and inspection openings ensure easy access and maintenance, reducing downtime to a minimum. Multi-level platforms are available as an option for easy access to all key components. Listening closely to customers and service engineers was key to the development of the innovative hygienic design of the NEPTUNE 4000.
MAXIMUM ENERGY EFFICIENCY / MINIMAL ENVIRONMENTAL IMPACT
The NEPTUNE 4000 is equipped as standard with high performance cyclones and thermal energy recovery technology to meet the highest demands for energy efficient production processes. Optional modular exhaust air purification systems ensure an even more environmentally friendly roasting process. Equipped with a hydrogen-compatible burner on request,, the NEPTUNE 4000 is not only the largest but also the most climate-friendly roaster on the market.
Overall, with the NEPTUNE 4000. PROBAT offers its customers the opportunity to achieve even higher yields with reduced energy consumption in the high output range. To enable seamless integration of the NEPTUNE 4000 into existing productionprocesses, PROBAT engineers are adapting the upstream and downstream system components to the processing capacities of the roasting machine. For example, the bin weighing scales for green and roasted coffee are currently being adapted to the maximum batch capacity of 880 kg of green coffee and 800 kg of roasted coffee. This is a crucial step for the market launch of the largest roasting machine of its kind, as the scales play an important role within a coffee plant; the entire plant control system is based on the production quantity data supplied by them. In combination with PROBAT's intelligent dosing systems, which enable a dosing accuracy of more than 99.87%, the bin weighing scales guarantee maximum process control regardless of production capacity.
