Designing the structures and details of the Arska dryers, minimizing the costs of drying and maximizing the quality of the outcome were the guiding design principles. The best features are hidden beneath the dryer´s surface and there are a lot of useful details to discover. Our solutions are the results of decades of experience and we develop them together with farmers based on their feedback.

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.

You decide the energy source

There are multiple energy options for Arska dryers. For example oil, gas or biofuels. Read more »

Arska grain dryer features

  • 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 from getting to the heater’s air pipe, which makes the dryer more fire-safe.
  • Grain moves as an equal layer at both sides of the air channels in the heat cell. Every other channel is an inlet air channel (perforated steel) and every other is an outlet air channel (steel net). Walls of air notches permeate air on the entire area. The 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 on 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.
  • The bottom fan keeps the base in vacuum pressure, so moisture and dust don’t reach inside the elevator.
