The SRM5E
1-5 kg (2–12 lbs.) Fluid Bed AIR Roaster
Roaster
SRM5E- FLUID BED Air Roaster
Robust. Savvy. Dynamic.
Crafted for precision in a compact footprint, the SRM5E is a 5kg (12 lb) fluid-bed roaster built for serious production environments. It delivers full control through real-time thermal data, IT/BT/Fan profiling, and automated curve tracking with manual override when needed. The result is repeatable, production-grade roasting with the responsiveness and consistency typically found in much larger systems, without the space, cost, or inefficiency.
WHAT makes the SRM5E different
Most “air roasters” are adapted systems. The SRM5E is not. It is a purpose-built fluid-bed platform engineered for specialty coffee from the ground up. Every design decision drives thermal stability, lower maintenance, and precise, repeatable flavor development across a true 5kg (12 lb) batch capacity.
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.
Electric Without the Tradeoffs
Electric roasting eliminates on-site combustion, reducing emissions at the roastery and simplifying installation in regulated environments. Paired with an efficient system design, it also lowers wasted energy and supports cleaner, more controlled operation.
Small Production
Designed for small-batch roasters and startups, the SRM5E delivers consistent, high-quality output - perfect for dialing in profiles, maintaining flexibility,
and growing with confidence.
Industrial-Grade Stainless Chassis
Built from 1/8" stainless plate with premium industrial 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 5 kg (12 lb) Capacity
Roast a full 5 kg (12 lb) batch, repeatedly. Rated capacity matches real production output, with consistent loft and even heat application across the entire batch range.
remote diagnostics, built in
Each roaster includes a dedicated VPN connection with its own IP address, allowing secure remote access for troubleshooting, updates, and support from anywhere in the world.
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.
FOUR 2mm ThermocoupleS
Bean, environmental, and metal temperature are tracked in real time. The metal probe drives the BBP protocol, locking in consistent charge conditions for tighter control and repeatable roasting.
Direct Software Integration
Built-in LAN connectivity allows seamless connection to roasting software like Cropster or Artisan, enabling real-time data tracking, logging, and profile control without additional hardware.
MAINTENANCE-FRIENDLY DESIGN
Straightforward access panels, standard fasteners, and modular assemblies reduce repair time, minimize downtime, and simplify spare parts inventory.
