Grain dryer FRT series

stationaryfixedwith dust filter

Overview
The FRT Series is a continuous-cycle grain dryer designed to provide homogeneous heat distribution, controlled process air circulation and low acoustic impact. A dedicated recirculation air architecture reduces noise, making these dryers suitable for installations where environmental comfort is required.

Why Choose the FRT Series

• Low acoustic impact — Dedicated recirculation air design with silencers and dampers to minimize noise and dust emissions.
• Controlled air dynamics — Precise management of inlet and recirculation airflows for even heat distribution and uniform drying without consumption peaks.
• Energy savings — Optimization of airflow and recovery of residual heat to lower fuel and energy consumption while maintaining fast and uniform drying.

Main Components (product visualizer)

• Main fans — Top-mounted to generate process airflow; fitted with silencers and dampers to reduce acoustic and dust emissions.
• Recovery fans — Located in the lower section to recover hot, low-humidity air and improve energy efficiency.
• Extraction device — Oscillating flaps ensure precise, uniform and constant grain outflow.
• Air ducts — Profiled ducts to promote grain flow and heat exchange between hot air and the grain.
• Stairs and walkways — External and internal access for inspections and routine maintenance, ensuring operator safety.
• Heat generator — In-line air burner for accurate temperature control; available for methane, LPG and diesel versions.
• Base frame — Supports the extraction device and hopper; load-bearing structure designed to resist seismic, wind and accidental loads.

Process Flow

• Air intake — Process air is drawn from the environment and heated.
• Hot air circulation — Hot air from the burner passes through the grain, transferring heat and absorbing moisture.
• Exhaust air expulsion — Moisture‑saturated air is expelled from the dryer.
• Product cooling — In the lower section the dried product is cooled with ambient air prior to extraction.
• Energy recovery — Hot air from the final drying phase is recovered and reintroduced to reduce consumption.

Complementary Technologies

• VAP System — STRAHL technology for additional reduction of dust emissions.
• Moisture Control System — Monitors product moisture to enhance process control.
• Extraction Speed Regulator — Option with inverter to regulate product extraction speed.
• Supplementary Temperature Monitoring — Additional probes for detailed temperature monitoring in dryer sections.
