Circular 16-cells silo
Modular storage built as an active production control layer
A 16-cell setup centers around one main structure. A rotating arm supplies coffee to all cells. A central hopper collects the coffee for weighing, dosing and blending when necessary. If your roastery layout allows, it's cost-effective to store and blend coffee. It can also handle complex routes with multiple intake points and dowstream conveying. At Roastworks, we design Circular 16-cells silos. They protect coffee quality and ensure production is predictable and scalable.

Key benefits
Flexible capacity in height & diameter
Capacity can grow by adding 50 cm layers. Expanding in height is the most cost-effective method to increase storage. This approach is viable when ceiling height and floor load capacity permit it. Diameter selection complements this when height is limited.
Integrated degassing for roasted coffee
Roasted coffee must rest after roasting. Built-in degassing valves allow CO₂ to escape while protecting the beans from external contamination. This design ensures stable grinding and packaging performance in the process that follows.
Dust treatment at discharge
When green coffee discharges, dust forms at hopper level. Local extraction captures this airflow and sends dust to filters or cyclones, preventing dust dispersion in production areas.
Bean integrity for roasted coffee
When the beans are discharged into the silo, they are guided via an open ‘zigzag’ chute, so that the beans do not suffer any major impact when they hit the silo cell or the coffee.
Software & recipe integration
Production software sends the exact coffee and quantity required downstream. Sixteen independent cells enable accurate recipe execution for blending before or after roasting. They also ensure full inventory traceability.

Questions? We're here to assist.
Capacity depends on production rhythm and storage duration. When ceiling height and floor strength allow it, increasing height is usually the most economical expansion method.
Yes. Multiple intake and discharge routes can be integrated, allowing coffee to be distributed downstream according to production needs.
Yes. Additional layers, routing paths, or downstream equipment can be integrated later when expansion is planned from the beginning.
