Grain dryer FRP series

Overview
The FRP Series meets the most challenging drying requirements through a dual-burner architecture that enables differentiated temperatures across multiple zones of the drying column. Designed for farms and collection centers, it delivers fast, uniform, and intensive drying for high‑moisture grain.

Why choose the FRP Series

• Dual burner — Two integrated burners increase available thermal power and allow flexible temperature management for demanding operating conditions.
• Multi-zone temperature control — Differentiated temperature zones along the column permit gradual and uniform treatment of grain, reducing thermal stress.
• Intensive drying — Optimized for high‑moisture grain to reduce drying time and ensure homogeneous results for intensive production needs.

Main components

• Main fans — Located at the top to generate dryer airflow; fitted with silencer and damper to limit noise and dust emissions.
• Recovery fans — Located in the lower section to recover part of hot low‑humidity air, improving energy efficiency and lowering fuel consumption.
• Extraction device — Oscillating flaps ensure precise, homogeneous and constant grain outflow.
• Air ducts — Profiled ducts designed to promote grain flow and efficient heat exchange between hot air and grain.
• Stairs and walkways — External and internal access for safe inspections and routine maintenance.
• Heat generator — In‑line air burner for accurate and uniform temperature regulation; available for methane, LPG and diesel.
• Base frame — Supports the extraction device with hopper; load‑bearing structure engineered for reliable extraction and resistance to seismic, wind and accidental loads.

Process flow

• Air intake — Process air is drawn from the environment and heated.
• Upper drying zone — Hot air from the first burner, at a lower temperature, crosses the central column zone.
• Central drying zone — Recovered hot air is heated by the second burner to a higher temperature and passes through the uppermost zone.
• Product cooling — In the lower section the dried product is cooled with ambient air prior to extraction.
• Exhaust air expulsion — Moisture‑laden exhaust air is expelled from the dryer.
• Energy recovery — Hot air from final phases is recovered and reintroduced to reduce fuel consumption.

Complementary technologies

• VAP System — Proprietary technology to further reduce dust emissions.
• Moisture Control System — Monitors product moisture to ensure controlled drying.
• Extraction Speed Regulator — Option with inverter to adjust product extraction speed.
• Supplementary Temperature Monitoring — Additional probes for more precise temperature monitoring across dryer sections.

Control systems
Intuitive management interface for real‑time control of the drying process, alert detection and result optimization.
