The AR Series, ideal for batch processing, works by using a drying recirculation system. The product passes through the drying column several times, ensuring uniform final moisture content and preventing thermal shock.
This process optimizes grain yield and quality, and the cooling process ensures the product is stored safely for a long time. It is the most flexible solution to achieve maximum precision and to get the most out of every harvest.
The machine’s construction and the ability to set specific programs allow for slow drying cycles and long tempering periods, particularly suited for the treatment of delicate products.
The AR Series enables the separate management of small production batches, essential in sectors such as organic and seed production, where lot distinction is a fundamental requirement.
Maintaining low temperatures and the ability to recycle the product multiple times, leveraging the natural fall within the drying chamber, preserves the seed’s germination capacity intact.
Thanks to its special internal geometry, the hopper ensures ideal grain flow and optimal movement toward the drying chamber.
Positioned at the top of the system, they generate the dryer's airflow. They are equipped with a silencer and damper to minimize acoustic and dust emissions into the environment.
Composed of oscillating flaps that allow a precise, homogeneous, and constant outflow of grain.
The duct profile is designed to promote grain flow and heat exchange between hot air and the grain to be dried.
Located both outside and inside the dryer, they provide safe and easy access for inspections and routine maintenance, ensuring maximum operator safety.
The in-line air burner ensures accurate and uniform temperature regulation. Available for methane, LPG, and also in a diesel version.
Supports the extraction device, is equipped with a hopper, and is designed to ensure precise and reliable extraction over time. The load-bearing structure is solid and resistant to earthquakes, wind, and accidental loads.
Air intake
External air enters the dryer to be heated and support the process.
Hot air circulation
External air heated by the burner, flows throught the grain releasing internal moisture.
Exhaust air expulsion
Exhaust air is blown out from the dryer, as it is saturated with moisture from the drying process.
Product cooling
Once the final moisture is reached, the burner shuts off. External air flows through the grain, ensuring controlled cooling, which is essential for stabilizing the product and preparing it for extraction and storage.
