Designing the structures and details of the Arska dryers, we paid attention to costs of drying and the quality of the outcome. The best features of the dryers can be found beneath the surface and there’s a lot of details. Our products have been developed based on the feedback received from farmers over many decades of experience.
Dries in demanding circumstances
Arska dryers are designed for northern conditions. They allow energy-efficient drying of very wet grain and maintain excellent quality.
Batch or continuous flow drying
In batch drying the grain moisture does not affect the end result. All Arska dryers are available as fast continuous flow dryers.
Features of Arska grain dryer
- Grain is pre-heated in the levelling cell.
- There are closing hatches on the highest heat cell for partial batches.
- Arska heat cells have a notch cell structure, where grain doesn’t swell and you can load the dryer full of grain. The structure prevents the grain to get to heater’s air pipe, which makes the dryer more fire safe.
- Grain moves as an equal layer at the both sides of the air channels in the heat cell. Every other channel is a inlet air channel (perforated steel) and every other is a outlet air channel (steel net). Walls of the air notches permeate air on the entire area. Outlet air channel’s permeability is remarkably higher compared to the inlet air channel, so the humidity exits efficiently and the internal remains clean.
- Spreading ridges supplement the mixing of the grain layer and prevent condensation.
- Depending of the model, Arska dryers have 4 – 12 feed tracks. Four-bladed cross track feeder works reliably with all grain species along the small grains.
- Feed speed is adjusted variably with a frequency inverter. Grain flow stays the same from start to finish of drying, regardless of grain moisture. Feed speed increases during the cooling automatically.
- Bottom fan keeps the base in vacuum pressure, so moisture and dust doesn’t reach inside the elevator.
