Conditioned drying in drying rooms
In areas with a high humidity level, drying with outside air is very limited. The drying process of seed with crop (‘on straw’) proceeds slowly and demands a lot of energy. Closed cells with a cooling-drying installation (heat pump) provide a solution and save a lot of energy. The cells are built around the drying installation.
Depending on the needs and use, the lay-out and measurements of the cells are determined: 1 or more row of boxes per cell or 1 large cell with drying on 2 sides, 3-4-5-6 boxes stacked high. Volumes up to 30 or 40 m³ per row are possible.
The advanced ABC processor controls the whole installation and dries the seed to the desired moisture content; the most suitable (dry) air (outside or inside air) is suctioned. The air will be cooled down to achieve the desired Absolute Moisture Content (AH, in gr/kg of air) of the air, using condensation. Afterwards the air will be reheated so it is able to absorb more air. The air from the product will become drier than the outside air, and internal air is automatically used for the remaining drying process.
In narrow cells or wide cooling-drying units, the outlet hatches are placed behind the inlet hatches.
