Power and Compatibility with Grain Dryers
| Type of grain dryer | Example brands/models | Recommended number of heat generators (nominal power 2000 kW) | Typical corn drying capacity (from 24% to 14%), t/day | Drying-agent connection interface | Compatibility with AgroWarm heat generators | Notes |
|---|---|---|---|---|---|---|
| Mobile dryers | Zafrani, Fratelli Pedrotti, Mecmar, Agrimec and others | 1 | 100–200 | Flanged connection of the air duct to the dryer fan | ✔ Confirmed | Automatic switch to cooling mode in 2 minutes; if an external cooler is used, drying capacity increases by 10–30%. |
| Modular dryers | Sukup, Farm Fans, AgroStar and other typical modules with 6–13 sections | 1 (for each drying module) | 100–250 (for each drying module) | Flanged connection of air ducts to each dryer module or to the common air plenum, if present (required) in the design | ✔ Confirmed | The zoned principle of grain heating and drying is preserved; it is possible to replace fan impellers, electric motors, or install an external fan. |
| Conveyor dryers | Alvan Blanch and similar | 1-2 | 200-500 | Flanged connection of the air duct to the dryer fan | ✔ Confirmed | Stable continuous supply of the drying agent. |
| Shaft dryers | Bonfanti, Mepu, Riela, Tornum, Strahl, Sokol, Bryg and others | 1-3 | 250-650 | Flanged connection of air ducts to the hot-air chamber of the grain dryer | ✔ Compatible | Possible operation with blowing and suction fans; external fans can be added if required. |
The power and capacity figures in the table are typical ranges. Exact selection is performed individually for your dryer (zone configuration, air flow, target moisture, etc.).
Conclusions on Power and Compatibility with Grain Dryers
- Proven compatibility with popular mobile dryer brands. Works with Zafrani, Agrimec, Fratelli Pedrotti, Mecmar and others; connection type — flanged connection of the air duct to the grain dryer fan.
- Wide power coverage for any dryer type. Recommended number of heat generators: mobile — 1; modular — 1 (for each drying module); conveyor — from 1 to 2; shaft — from 1 to 3.
- Sufficient drying capacity. In total, the heat generators cover grain dryers from 100 to 650 t/day (from 24% to 14% moisture), depending on the dryer type, allowing scaling from farms to large elevators.
- Stable drying-agent quality. A combination of approximately 90% atmospheric air + 10% high-temperature gases with a mixer–separator up to 70,000 m³/h per heat generator provides clean air without smoke or odors.
- Fast mode dynamics. Reaching the set temperature in 5–10 minutes, switching to cooling for batch dryers in 2–3 minutes, and maintaining temperature with ±3 °C accuracy.
- Enhanced safety and service life. The flame does not touch the walls; thanks to burner cooling, refractory concrete operates at t < 700 °C; only a small portion of fuel (5 kg) is always in the burner, so the system is non-inertial and safe even in case of power loss.
- Flexible connection and fast installation. Standard flanged joints, compact footprint of ~8 m², typical installation and commissioning — about 2 working days.
- Conclusion: one product line of heat generators covers all main grain dryer types — from mobile to shaft — with guaranteed compatibility, stable temperature and high energy efficiency. For precise power selection, an individual calculation should be performed for your dryer and productivity targets.
