AG-Projekt - Model SD ESR -Canopy Dryer with External Recuperative Duct

Cereal, rapeseed or maize grains for drying are delivered to the hopper hopper segment from above using an external transport device. It fills all cooling and drying segments, and largely the charging segment, creating a pile in it.

The air heated by the heating furnace to a certain temperature is drawn through the exhaust fans to the warm air duct, then flows under the inlet roofs of each drying segment. The air, passing through the grain layer, receives moisture from it and gets under the canopies with axes shifted in relation to the inlet canopies. Moist air passes to the cold air duct, from which exhaust fans lead them outside. This process of drying grain takes place at all levels of drying the columns.

The grain filled from above moves down and, passing between the roofs, is heated and dried. After passing the grain through all drying segments, the column goes to the cooling section, in which cold air at ambient temperature flows through the grain, lowering its temperature to almost ambient temperature. After cooling, the dried material moves to the selection element. Dialing efficiency can be precisely adjusted from a few kilograms to several dozen tons per hour. This makes it possible to precisely adjust the grain flow through the dryer so that its final moisture content is correct.

The selection element has a mechanism of sliding shelves, allowing the grain to pour into the hopper, from where it spills outside the dryer to a series of transport devices that transfer them most often to warehouses, forwarding silos or for further processing.
