Key Advantages
1. More Balanced Flavor Profile:
Conductive heat from the drum enhances sweetness and body, while convective hot air improves clarity and uniformity—ideal for single-origin beans, espresso blends, and a wide range of roast levels.
2. Superior Heat Uniformity and Batch Consistency:
Hot air effectively removes moisture and smoke from the drum, minimizing localized overheating and the accumulation of chaff, ensuring a consistent roast from the bean surface to the core.
3. Intuitive Push-Button Controls:
Parameters such as heat intensity, airflow (damper), and roast time are adjusted via simple, intuitive buttons—making it easy for café staff, roasting students, and small-scale producers to achieve consistent results.
4. 1kg Small-Batch Capacity for Versatile Use:
Perfect for in-store roasting, sample profiling, new product testing, small-batch custom production, and early-stage business operations, all while keeping the cost of experimentation low.
5. Efficient Smoke and Chaff Management:
Applications
📍 1. Specialty Coffee Shops (In-Store Roasting)
Shops aiming to roast and sell on-site to highlight "freshly roasted today" appeal, despite limited back-of-house space, a lack of dedicated roasters, and high staff turnover.
Solution: 1kg small-batch capacity aligns with daily sales volume; a hybrid (semi-direct/semi-hot air) heating system balances body and clarity; intuitive, easy-to-learn control panel; compact design with excellent thermal insulation and low noise.
📍 2. Sample Roasting and Cupping/Bean Selection
The need to quickly roast small samples for cupping and comparison after green bean procurement—requiring minimal bean usage, reproducible roast profiles, and easy cleaning.
Solution: Capable of testing batches from a few hundred grams up to 1kg; features an observation window and sampling trier; roast parameters can be recorded for replication; the drum and chaff collector are detachable for cleaning.
📍 3. Roasting Training and Demonstrations
Requires equipment that is accessible and reliable, allowing students to intuitively grasp the relationships between heat, airflow (damper), and the "first crack."
Solution: Mechanical dampers provide a clear, direct cause-and-effect relationship; the observation window is ideal for group viewing; low maintenance costs make it well-suited for frequent instructional use.
📍 4. Micro-brands and Small-Batch Customization
Managing a wide range of SKUs with small order volumes requires the flexibility to switch recipes while controlling investment and the costs of trial and error.
Solution: 1kg batch capacity supports agile, small-order production; multiple parameter memory slots; highly adaptable for various roast levels (light to dark) and blends; supports OEM and certified configuration options.
📍 5. Store Replenishment and Short-Cycle Inventory
Frequent, small-quantity replenishment for multiple locations, preventing flavor degradation and excess inventory associated with large-batch roasting.
Solution: Allows for daily, store-specific batching; a cooling system isolated from the roasting chamber ensures consistency during continuous operation; rapid heat-up and recovery times allow for short per-batch cycles.
📍 6. Home Roasteries/Studios (Startups)
Ideal for those with limited budgets and space, who are sensitive to installation requirements, noise levels, and smoke exhaust.
Solution: Electric heating models offer easy installation; the compact footprint fits on standard workstations; the insulated roaster body keeps surface temperatures low and prevents the ambient room temperature from rising. 7. Exhibitions, Markets, and Mobile Coffee Cart Demonstrations
📍 8. R&D and Blend Development
Requires translating sensory evaluation results into traceable data to build a standardized recipe library.
Solution: Should include dual probes (BT/ET) for integration with Artisan software, allowing for comparison against reference (background) roast profiles.

Main Components
- It is divided into six major modules: the heating system, the drum, the airflow and exhaust system, the cooling system, the control system, and the frame and housing. The "hybrid" (semi-direct-fire/semi-hot-air) roasting method is characterized by a dual-path heat supply: the heat source heats the outer wall of the drum (via conduction) while simultaneously directing hot air into the interior of the drum (via convection).
Working Principle
Workflow 1. Preheating Phase: Upon startup, the heating system preheats the roasting drum to ensure the machine reaches a stable operating temperature. Once preheating is complete, the green beans can be loaded. 2. Loading and Temperature Rise: Approximately 1kg of green coffee beans is loaded into the roasting drum. As the drum rotates, the beans are tumbled, ensuring even heat distribution. 3. Dehydration and Flavor Development: Moisture on the surface of the green beans gradually evaporates, and the color shifts from green to yellow. This is followed by the Maillard reaction and caramelization, which develop flavor notes such as nuttiness, caramel, and floral or fruity aromas. 4. First Crack and Determining the End of Roasting: When the bean temperature reaches approximately 180–195°C, the coffee beans undergo the "first crack." The operator determines the optimal time to discharge the beans by observing their color through the viewing window, listening for the cracking sounds, and monitoring the temperature/time display on the control panel. 5. Cooling and Stabilization: Once the desired roast level is achieved, the beans are discharged into a cooling tray. A cooling fan rapidly removes residual heat, halting the roasting process and preventing the beans from roasting any further.
Detailed Features
- ▸A hybrid (direct-flame/hot-air) coffee roaster utilizes two parallel heating pathways: the outer surface of the roasting drum is heated by flames or heating elements, providing conductive heat (which contributes to sweetness, body, and heat penetration to the bean core), while hot air is channeled into the drum, providing convective heat (which ensures uniformity, efficient moisture removal, and the venting of smoke and humidity). With the ability to independently adjust heat intensity and airflow via a control panel, operators can achieve flavor profiles and batch-to-batch consistency comparable to professional-grade equipment, all with a relatively low learning curve.
Packaging & Shipping
The unit is packed for export in a fumigation-free plywood crate. It is wrapped in PE film for moisture protection, with EPE foam corner protectors for cushioning, and secured to a wooden base with bolts—ensuring robust protection for critical components such as the glass viewing window, control panel, and fan. The standard crate dimensions are approximately 1200 × 820 × 1050 mm, with a gross weight of about 165 kg. We support FOB, CIF, and DDP shipping terms and can coordinate with your designated freight forwarder. Each shipment includes a packing list, invoice, certificate of origin, CE certificate, and user manuals in both Chinese and English. Before leaving the factory, every unit undergoes a no-load test run, with photographic records kept, ensuring the equipment is ready for immediate use upon arrival.
