The SRM9E
2-9 kg (4–20 lb.) Fluid Bed Roaster
Roaster
SRM9E- Fluid Air Bed Roaster
PRECISION AT PRODUCTION SCALE
Finally roast with true, repeatable control. The SRM9E is a 20 lb (9 kg) fluid-bed roaster engineered for specialty coffee producers running real production. Real-time temperature feedback, responsive heat and airflow, and stable batch conditions deliver consistent quality with lower operating cost over time.
WHAT makes the SRM9E different
Control the Environment, Not the Guess
Inlet temperature and fan speed define the roasting conditions directly. You are not chasing burner percentages or waiting on the system to catch up.
Full Batches That Actually Hold Up
Run 9 kg loads without losing loft or even heat application. No drop-off at capacity.
Fast Response When It Matters
Heat and airflow adjustments show up quickly in the roast, making it easier to stay on profile and correct in real time.
Profiles That Translate to Production
Set your IT/BT/fan targets and run them repeatedly without drift from batch to batch.
Built to Run All Day
Designed for back-to-back roasting with stable conditions from the first batch to the last.
CHOOSE HOW YOU WORK:
Sivetz Mode
Manually control inlet temperature and fan speed in real time.
IT/BT Profile Mode
Program step-based profiles using inlet temperature, bean temperature, and fan speed targets.
Bean Temperature Tracking Mode
Automatically follow a pre-programmed bean temperature curve for consistent, repeatable results.
GROWING PRODUCTION
Built for roasteries scaling into higher volume, the SRM9E delivers reliable throughput of up to 2,000 lbs (900 kg) per week while maintaining precise control and consistent roast quality as demand increases.
INDUSTRIAL-GRADE STAINLESS CHASSIS
Built from 1/8" stainless plate with premium components, the structure resists flex, limits hotspot formation, and maintains integrity under years of continuous production use.
Integrated Cooler
& Stirring ArmS
A dedicated cooling blower and mechanical agitation stop development quickly and consistently. Fast, efficient cooling with no manual stirring.
CORE ADVANTAGES
True 9 kg (20 lb) Capacity
Full 20 lb batches, back to back. No derating, no partial loads. Stable loft and uniform heat application from small batches to full production loads.
IT/BT Control & Automated Profiling
Control the roast directly through inlet temperature (IT) and track progress with real-time bean temperature (BT). Set and adjust airflow through fan speed targets alongside heat, giving you precise control over both energy and bean movement. The result is tighter control, faster response, and fully repeatable automated profiles.
Lower Operating CostS
Efficient heat transfer and industrial-grade components reduce energy waste and minimize downtime, driving down cost per lb over the life of the machine.
Five 2mm ThermocoupleS
Multiple real-time data points across bean, air, and metal temperatures. The metal probe standardizes BBP, eliminating variability at charge and improving batch-to-batch consistency.
Fine Control
& Repeatability
Fast, responsive heat and airflow give you tight control over Rate of Rise, making it easier to manage dense high-elevation coffees and delicate processed lots with consistency.
MAINTENANCE-FRIENDLY DESIGN
Straightforward access panels, standard fasteners, and modular assemblies reduce repair time, minimize downtime, and simplify spare parts inventory.
Designed for Modern Profile Strategy
Shape the roast with control that holds up in production. From early drying through Maillard and post-first crack development, the SRM9E delivers responsive control and clear, actionable data so you can consistently express origin, process, and fermentation character.
- Data Density: Multiple temperature inputs support deeper roast analysis and tighter profile control.
- Thermal Headroom: Maintain profile integrity across back-to-back batches without drift.
- Uniform Loft: Even bean movement eliminates scorching and reduces underdevelopment.
- Fast Cool: Rapidly stops development to lock in target flavor.
