- the interior of the vacuum chamber 102 is designed so that no dirt can accumulate and drops of liquid, in particular condensate, do not fall onto the workpiece 116.

- the liquid outlet 176 preferably opens at a lowest point of the inner space 118 of the vacuum chamber 102 into this inner space 118. Furthermore, the liquid outlet 176 is provided with a shut-off device 178.
- the above-described apparatus 100 for drying workpieces after a cleaning operation functions as follows:
- the workpiece 116 is cleaned in a device 100 upstream of the cleaning device, preferably after a machining operation.
- the workpiece 116 is preferably a metallic workpiece.
- the workpiece 116 may be an engine component, such as an engine block or a cylinder head.
- the workpiece 116 may in particular have recesses or other scooping parts in which cleaning liquid can accumulate.
- the workpiece 116 is introduced into the vacuum chamber 102 immediately after the cleaning operation.
- the workpiece 116 is not subjected to a blow-off process before it is introduced into the vacuum chamber 102.
- the usual predrying process in a blowing zone is thus dispensed with in the device 100 described here and the drying method carried out in order to avoid back-soiling through such a predrying process.
- the movable between a loading position and a working position workpiece holder 112 forms a shuttle system by means of which the vacuum chamber 102 can be loaded with the workpiece 116 and by means of which the workpiece 116 can be discharged from the vacuum chamber 102 again.
- a roller conveyor for loading and unloading the vacuum chamber 102 with the workpiece to be dried 116 can therefore be omitted. This offers the advantage that a small vacuum chamber 102 can be used and that no dirt pockets form which frequently occur when using a roller conveyor.
- the workpiece holder 112 is brought into the loading position shown in solid lines in Fig. 1, in which the workpiece to be dried 116 is placed on the workpiece holder 112 and locked by means of the locking device 114 on the workpiece holder 112.
- the workpiece holder 112 is moved from the loading position into the working position shown in broken lines in FIG. 1, wherein at the same time the access opening 108 of the vacuum chamber 102 is closed gas-tight by means of the lid 110.
- the interior 118 of the vacuum chamber 102 is evacuated by the vacuum generator 138 to a final pressure in the range of about 30 mbar or less, preferably in the range of about 5 mbar or less.
- Critical locations of the workpiece 116 that do not become dry by vacuum drying alone, for example, deep holes on the workpiece 116, are delivered by the blowing device 146 through the blowing nozzles 148 with short blowing medium pulses (having a duration of, for example, 1.0 second or less, preferably of about 0.5 sec or less).
- the pressure of the blowing medium can thereby correspond to the atmospheric pressure or, when compressed air is used, be above the atmospheric pressure, preferably at least approximately 1 bar, in particular at least approximately 5 bar, above the atmospheric pressure.
- the pressure in the vacuum chamber 102 is maintained at the above-mentioned low final pressure for a predetermined period of time.
- the workpiece 116 can be subjected to blowing medium pulses.
- the vacuum chamber 102 is vented.
- blow nozzles 148 which are directed onto the workpiece 116, are supplied with blowing medium, which has been guided via the fine filter 158.
- the blowing medium used for aeration may be the same medium which has been used to produce the blowing medium pulses at the beginning of the drying process, or may be a different blowing medium.
- ambient air or compressed air preferably from a compressed air network, can be used for ventilating the interior 118 of the vacuum chamber 102.
- the supplied blowing medium expands upon entry into the vacuum chamber 102, thereby cooling the blowing medium and, in turn, cooling the workpiece 116 toward which the blowing media jets are directed upon aeration of the vacuum chamber 102.
- the distance of the workpiece temperature from the room temperature is reduced so that a subsequent cooling process of the workpiece 116 inside or outside the vacuum chamber 102 can be shortened or completely eliminated.
- the device 100 is further provided with a device (not shown) for rotating or tilting the vacuum chamber 102, with which 1 and 2, in which the longitudinal direction 132 of the vacuum chamber 102 is oriented substantially horizontally, the vacuum chamber 102 can be brought into an end position in which the longitudinal direction 132 of the vacuum chamber 102 is oriented substantially vertically.
- the transfer of the vacuum chamber 102 from the starting position into the end position preferably takes place after the introduction of the workpiece 116 into the interior space 118 of the vacuum chamber 102 and before or during the execution of the vacuum drying process.
- the vacuum chamber 102 is preferably moved back again from the end position to the starting position.
- this variant of a device 100 for drying workpieces 116 after a cleaning process in terms of construction and operation is the same as in the embodiment illustrated in FIGS. 1 and 2, to the above description of which reference is made.
- a second embodiment of a device 100 for drying workpieces 116 after a cleaning process shown in FIGS. 3 and 4 differs from the first embodiment shown in FIGS. 1 and 2 in that the longitudinal direction 132 of the vacuum chamber 102, and thus in particular also the longitudinal central axis 136 of the vacuum chamber 102, not substantially horizontally, but substantially parallel to the vertical 180 is aligned.
- This embodiment of the device 100 is particularly recommended if the cleaning liquid remaining in the workpiece 116 after the cleaning process can flow out of the workpiece 116 more easily when the workpiece 116, that is to say the vertically aligned longitudinal direction 182 of the workpiece 116, is stationary.
- the first embodiment of a device 100 is preferred in which the longitudinal direction 132 of the vacuum chamber 102 at least during the loading of the vacuum chamber 102 with the workpiece 116 is aligned substantially horizontally, since in this arrangement the handling of the workpiece 116 and its locking on the workpiece holder 112 are simpler.
- the second embodiment of a device 100 shown in FIGS. 3 and 4 differs from the first embodiment in that the liquid discharge 176 in the second embodiment is not disposed on the peripheral wall of the main body 104 of the vacuum chamber 102, but instead at the top of the Closing portion 106 of the vacuum chamber 102 opens into the interior 118 of the vacuum chamber 102. It is thereby achieved that, even in the second embodiment, the liquid can be discharged from the lowest point of the vacuum chamber 102 through the liquid outlet 176 from the vacuum chamber 102.
- the evacuation line 142 preferably opens into the interior 118 of the vacuum chamber 102 through the peripheral wall of the main body 104 of the vacuum chamber 102.
- the inside of the lid 110 is concavely curved, it is achieved that the inner wall 164 of the vacuum chamber 102, in particular of the vertically disposed over the workpiece 116 located in the working position part of the inner wall 164, is curved, so that there is no Accumulate liquid and can fall down on the workpiece 116.
- the second embodiment of a device 100 shown in FIGS. 3 and 4 for drying workpieces 116 after a cleaning process has the same structure and functionality as in FIG. 1 2 and 2, the above description of which is incorporated herein by reference.
- a device for rotating or tilting the vacuum chamber 102 is present, by means of which the vacuum chamber 102 from the starting position shown in Figs. 3 and 4, in which the longitudinal direction 132 of the vacuum chamber 102nd is oriented substantially vertically, can be brought into an end position in which the longitudinal direction 132 of the vacuum chamber 102 is oriented substantially horizontally.
- scooping parts of the workpiece 116 which still remain filled with cleaning fluid when the workpiece 116 is in the starting position, can be swiveled out during the rotation by, for example, approximately 90 °.
