The invention relates to a machine that is used for the thermodynamic treatment of air. The invention also relates to a device for treating products, in particular, agricultural products such as those packed in bales or bunches, said device comprising at least one machine for the thermodynamic treatment of air in accordance with the invention. In addition, the invention relates to the products resulting from such treatments using the inventive device. According to the invention, the agricultural products are disposed in the lower part (7) of a dryer (1) which also comprises an upper part (6) that is separated from the aforementioned lower part (7) by means of a canvas strip (5). A treatment machine (2) is used to suck up the air to be treated by means of a suction line (11) and, subsequently, to blow out the air treated by the treatment machine (2) by means of an air outlet line (10). A drying operation is performed, particularly in relation to the agricultural products, using said treatment machine (2), by drying the air sucked up through the agricultural products (8, 9) in the dryer (1). Using distribution chambers, said machine can be connected to the blowing flow or the suction flow of a main fan.
