Buhler RoaStar - Continuous Dryer/Roaster
The RoaStar is designed for gentle, high-quality roasting of cocoa beans, hazelnuts, peanuts, almonds and other types of nuts and seeds. The vertical duct system and cutting-edge convection give you full control over flavor, color and aroma.
Precise control
The RoaStar precisely controls and monitors temperature and timing so that raw materials are roasted gently and to exactly the right degree. This allows you to develop the very best flavor, color and aroma for superior quality, every batch.
The RoaStar’s advanced low-temperature vapor-heating process ensures significant energy savings, while heat exchangers recover precious exhaust energy for reuse in the roaster to keep energy costs low.
Configured for your product and capacity needs
The innovative RoaStar’s modular system allows you to meet different capacity requirements for a wide range of raw materials. Its vertical design gives it a small footprint that you can easily accommodate on your factory floor.
Extremely gentle treatment of raw materials is key when developing the highest quality product. The vertical product duct system used in the RoaStar allows your materials to move under the influence of their own weight alone. This prevents fat leaking from kernels to shells and guards avoiding damage to the surface of nuts during the roasting process.
Much of the exhaust energy that would otherwise be lost in the roasting process is recovered by heat exchangers for reuse. Steam heating both ensures that exhaust air is free from sulphur and nitrogen oxides and allows the RoaStar to use biomass combustion. Fueling the system using byproducts such as cocoa shells rather than fossil fuel gives you a supremely efficient CO2-neutral operation.
The advanced automatic control system monitors every part of the roasting process to ensure it operates without a hitch. Intuitive displays present vital information in a clear and user-friendly way, allowing your operators to respond with adjustments quickly and easily. With the integrated fire detection system constantly checking each parameter, safety is a priority.
