  • the first two washing ramps 18 and 19 are carried by a main shuttle 22, mounted vertically movable near the first side wall 2 of the enclosure 1.
  • the main shuttle 22 is guided in its vertical movement along vertical guides 23 integral with the walls of the enclosure 1, and is driven by a first traction cable 24 solicited by a first winch top 25.
  • the other two washing ramps 20 and 21 are carried by a shuttle secondary 26 which is itself in vertical displacement along second vertical guides 27 and which is driven by a second traction cable 28 itself biased by a second upper winch 29.
  • the main shuttle 22 is box-shaped, with an air inlet 22c side opposite the side wall 2, and with a slot-shaped air outlet 22e on the opposite side.
  • the main shuttle 22 contains a first ventilation means 22a, consisting of a turbine with axial suction and radial discharge, driven by a 22b electric motor.
  • the turbine 22a draws air through the axial inlet 22c at adjacent to the side wall 2, and delivers air through a radial passage 22d towards the lower compartment of the box with the 22nd lateral outlet in the form of a slot at the end of a progressive dihedral narrowing zone 22f.
  • the box thus formed constitutes a suitable guide pipe.
  • a heating element 22g is disposed for example downstream of the turbine 22a. In this way, the shuttle 22, by rotation of the motor 22b and the turbine 22a, can produce a hot air flow in the form of a horizontal blade directed towards the side wall opposite 3 that is to say towards the center of the enclosure 1.
