Coffee Roaster Agitator Arm is constructed from thermally stabilized stainless steel alloys with low thermal expansion coefficients (typically below 11 µm/m°C). This suppresses thermal deformation during repeated exposure to roasting temperatures exceeding 500°C. The result is maintained arm integrity, constant rotational clearance, and zero contact-induced wear on the drum wall.
Coffee Roaster Agitator Arm is machined with tight concentricity tolerances of ±0.02 mm, ensuring zero axial deflection during high-speed rotation. This eliminates shaft misalignment, reduces eccentric load on rotary bearings, and prevents gear tooth wear from uneven torque distribution. Axial stability directly translates into reduced motor load and longer drive system life.
Coffee Roaster Agitator Arm features a balanced mass profile and low moment of inertia, minimizing oscillations and torsional vibrations during startup and deceleration. The arm’s structure is FEA-tested to avoid stress concentrations, allowing stable performance at variable RPM ranges without impacting the roast profile or mechanical coupling.

Supports precision profiling with low-tolerance mechanical motion, critical for replicating roast curves across small-batch specialty coffee production.
Integrates with servo-controlled roasters, offering synchronized rotation with variable speed control and minimal backlash for feedback-driven roasting automation.
Maintains bean suspension and contact homogeneity when used in conjunction with upward airflow, optimizing heat transfer and roast uniformity.
Facilitates controlled agitation within pilot roasters used for process validation, material testing, and thermal transfer characterization in R&D environments.
Used as a precision-fit component within OEM assemblies requiring exact shaft alignment and durable mechanical coupling under thermal cycling.
Serves as a replacement arm in retrofitted roasters where original agitators fail due to misalignment, fatigue, or thermal expansion mismatch.
Coffee Roaster Agitator Arm is fabricated with a non-porous, electropolished surface (Ra < 0.4 µm), reducing the tendency of coffee oils and particulate matter to adhere. This ensures compliance with hygienic design standards, simplifies manual cleaning, and reduces post-batch contamination between roast cycles.
Additionally, the Coffee Roaster Agitator Arm features smooth radii at junctions and fully welded transitions, eliminating crevice zones where residues typically accumulate. This design supports high-pressure washdown compatibility and ensures faster drainage during cleaning-in-place (CIP) operations, meeting the sanitary requirements of food-grade processing environments.

Frigate uses precision CNC machining and dynamic balancing during production to control mass distribution across the entire arm length. Each unit is tested for moment imbalance to avoid rotational vibration during operation. This ensures the agitator runs without inducing extra load on the drive shaft. Balanced arms directly reduce bearing wear and improve motor efficiency.
Frigate selects stabilized austenitic stainless steels like AISI 310 or 253MA for arms used above 500°C. These materials retain yield strength at elevated temperatures and resist thermal creep. They maintain dimensional stability during continuous thermal cycling. This ensures the arm remains aligned with the drum wall across all roast batches.
Frigate uses TIG welding with full penetration joints on blade-arm assemblies. Welds are inspected via dye penetrant and X-ray for crack and porosity detection. Post-weld stress relief is applied to minimize residual stresses. This prevents premature fatigue failures under rotational and thermal loads.
Frigate applies electropolishing to achieve a surface roughness of Ra < 0.4 µm. This reduces surface energy and prevents sticking of chaff and coffee oils. The smooth finish improves washdown effectiveness in cleaning cycles. It also enhances corrosion resistance in acidic roasting environments.
Frigate uses CAD-controlled machining and CMM inspection to ensure all arms match original OEM specifications. Every arm is verified for pitch circle, shaft bore, and blade alignment. This allows easy interchangeability without field rework. Customers can replace damaged arms without recalibration of the roasting system.
