Industrial drum roaster for coffee beans
In industrial coffee production, achieving consistent roasting profiles while handling large volumes can be challenging. Ensuring uniform flavor development and efficient cooling during roasting is critical for producing high-quality coffee.
Achieve uniform flavor and efficient cooling
The Neptune 1500/3000 by Probat is an advanced drum roaster designed for high-capacity coffee roasting. This horizontally rotating drum roaster can handle capacities of 1,500 and 3,000 kg/h. It utilizes a burner to generate thermal energy, which is directed through and around the drum, roasting the coffee beans via both conduction and convection. The roasting times range between 8 and 20 minutes, ensuring intensive flavor development. The system includes features such as variable emptying speed, an optimal blending shovel mechanism, and effective cooling to maintain product quality. Suitable for light to extremely dark roasts, this roaster is available in natural gas, propane, and hydrogen-powered versions.
