- the heat radiators are preferably directed onto the workpiece carrier 12 or the workpieces and, as in the FIGS. 1 and 3, as a stationary heat radiator 10a arranged stationary on a container inner wall or, as shown in FIG. 4, as a rotatable heat radiator 10b on a pipe loop 8c arranged parallel to the pipe loops 8a, 8b of the spray unit, which together with the spray unit 8a, 8b is rotatably mounted about the axis AA 'of the treatment container.
- the heat radiators 10a, 10b are, as can be seen in particular in FIG. 1, in the form of elongated elements which extend in the treatment container 1 in the axial direction.
- the liquid vapors still present in the cleaning container 1 from the cleaning process are sucked off via the second suction opening 6. This serves to accelerate the drying process, since the suction device connected to the second suction opening 6 enables a greater gas exchange than the vacuum pump.
- the temperature of the gaseous medium introduced via the spray unit 8a, 8b is between 50 and 200 ° C., depending on the temperature sensitivity of the workpieces to be dried, and accordingly the pressure of the introduced gaseous medium varies between 0.5 bar and 10 bar, with the inside of the container a vacuum between 0.2 bar and 0.6 bar is formed.
- the device according to the invention also enables a further drying process in which the workpieces are dried by the heat radiation emitted by the heat radiators 10a, 10b in connection with one in the interior of the container the vacuum pump generated vacuum occurs.
- This method is particularly suitable for drying components which are mechanically less resilient, such as electronic components, which would be destroyed by the high pressure of the gas jets if the drying method described above were used.
- the workpiece carrier 18 rotates in order to expose the workpieces to the heat radiation from all sides. Furthermore, in the device shown in FIG. 4, there is the possibility of rotating the heat radiators 10b through the tube loop 8c around the workpiece carrier 18 and leaving the workpiece carrier 18 stationary, or of rotating the workpiece carrier 18 and the tube loop 8c in opposite directions in order to keep the workpieces permanent exposed to heat radiation from different directions.
- the liquid vapor which forms in the interior of the container is drawn off via the first suction opening 7 and the vacuum pump.
- a gaseous medium in particular air, is preferably briefly blown into the interior of the container via one of the pipe loops of the spray unit 8a, 8b in order to briefly increase the pressure in the interior of the container and thus reduce the vacuum.
- the air introduced is sucked off via the vacuum pump, the liquid vapors being removed more quickly from the treatment container 1 by this gas exchange, which is increased briefly.
- the introduced air also causes liquid residues to be blown away from the workpieces, so that the adhering liquid residues evaporate more quickly.
