Main Components

• Automatic Bean Feeding System: Includes a hoist, screw conveyor, or pneumatic feeding mechanism to ensure precise, metered loading of green beans.
• Roasting Drum: Constructed from double-layered stainless steel or cast iron, featuring internal mixing vanes that ensure beans tumble continuously for uniform heat distribution.
• Heating System: Utilizes gas burners or electric heating elements to provide a stable, controllable heat source.
• Hot Air Circulation System: Employs a blower and ductwork to circulate hot air into the drum, facilitating convective heating.
• Airflow Control (Damper): Regulates air intake and exhaust, influencing the rate of temperature rise and the clarity of the coffee’s flavor profile.
• Temperature Sensing System: Equipped with probes for both bean temperature and environmental temperature, providing real-time data to support roast profile control.
• PLC/Touchscreen Control System: Enables programmable roast profile management, parameter configuration, batch monitoring, and data export.
• Observation Window & Sampling Spoon: A high-temperature-resistant glass window allows for real-time monitoring of bean color, while a sampling spoon enables the operator to check the roast progress mid-process.
• Automatic Bean Discharge Mechanism: Automatically opens the discharge gate once the target roast level is reached, transferring the roasted beans into the cooling tray.
• Independent Cooling Tray: Features mixing arms and a cooling fan to rapidly lower bean temperature within 1–3 minutes.

Working Principle

The 15kg fully automatic coffee roaster operates through a closed-loop process: automatic green bean loading, roasting, profile control, automatic discharge, rapid cooling, and data logging. Automatic Green Bean Loading: Green beans are transported into the roasting chamber via a bucket elevator, screw conveyor, or pneumatic loading system, ensuring precise, metered input. Roasting: The machine utilizes gas, electric, or hybrid heating to generate hot air. Combined with a rotating drum or a hot-air fluidization system, this ensures the coffee beans are heated evenly as they tumble or circulate in the hot airflow. Profile Control: A PLC/touchscreen system monitors parameters such as bean temperature, airflow temperature, and rate of rise (RoR) in real time. It automatically adjusts heat intensity, damper settings, and timing according to a pre-set profile, precisely managing key stages—such as the yellowing phase, first crack, development phase, and the final discharge point. Automatic Discharge: Once the target roast level is reached, the machine automatically opens the discharge gate, transferring the roasted beans to the cooling tray; this minimizes manual intervention and batch-to-batch inconsistency. Rapid Cooling: An independent cooling system—utilizing powerful airflow, agitation, and cold-air circulation—quickly lowers the bean temperature, halting the roasting process to lock in flavor and color. Smoke and Chaff Management: Chaff, smoke, and hot exhaust gases generated during roasting are processed via a cyclone separator, exhaust system, or afterburner, ensuring a stable production environment. Data Logging: The system records the roast profile and production parameters for every batch. This data can be exported for quality traceability, recipe replication, and team management.

Packaging & Shipping

Main Unit Packaging: Housed in a fumigation-free plywood crate, with the interior secured using EPE foam, bubble wrap, and wooden bracing to prevent damage from vibration or impact during transit. Accessory Packaging: Components such as the control box, bean loader, chaff collector, piping, and tools are packed separately and labeled with corresponding reference numbers to facilitate on-site inventory checks and installation. Protective Reinforcement: Fragile elements—including glass viewing windows, touchscreens, and sensors—are fitted with protective corner guards or individual cushioning; the exterior of the crate is reinforced with steel or plastic strapping.
