On a suction of the air flow on the opposite side of the drying racks preferably waived.
- the moldings are in one layer Drying rack arranged. Through a multiple arrangement of blowing devices with an offset arrangement on both sides compared to the drying racks, the dry goods be reversely blown from the front and rear.
- the dry air can be conditioned in different ways. This can be done by separate dry zones and / or stationary dynamic with an oscillating change of Temperature and / or humidity happen. This allows the drying progress even more evenly and accelerate at the same time. The overall result is a shorter one Drying time without sacrificing dry quality goes.
- the dryer can be used with a suitable control for oscillating conditioning be equipped. This requires little construction and also allows retrofitting of existing systems.

- Your Outlets (28) open into conically widening air ducts (8) that extend to the drying rack (7) and in there immediate vicinity of the frame (15) or Mold trim (6) end.
- a diffuser (13) is arranged, which the air flow (14) evenly and preferably as a curved Perforated plate is formed (see FIG. 3).
- the Air guide channels (8) abut each other on the drying rack (7) and together form the aforementioned outlet opening (12), which extends over the entire side surface of the Shaped trim (6) extends.
- the drying racks (7) are preferred in size matched to the size of the moldings (6).
- the moldings (6) are further arranged so that they on both Sides and above are surrounded by a free space (21) is chosen so large that the speed of the Holes (20) directed flow substantially the same great as the speed of through the open spaces (21) is directed air flow.
- the size of the free spaces (21) depends on the number and size of the holes (20). In practice, the free spaces (21) have a width of approx. 1 to 4 cm.
- the height of the support strips (19) can be adjusted or from the start to the height of the moldings (6) be adjusted.
- the sides of the moldings (6) by means of a suitable loading technology when loading the Drying racks (7) ensured.
- Side clearances at the edges of the molded trim (6) are preferably movable screens (16) on the frame (15) arranged. They can be plugged in.

- temperature and / or humidity of the Air flow can be kept constant.
- Embodiment will be temperature and / or relative Humidity of the dry air (14) in the partitioned zone (2) or the complete drying chamber at least oscillating in stages, changing the values fluctuate rhythmically around or at a preset value.
- the drying air is conditioned via a suitable air conditioning (29).
- a suitable air conditioning (29).
- This can be designed differently.
- the air conditioning device (29) can also be a Heating (36) for the circulating air and / or the outside air or Have fresh air.
- the air conditioner (29) is in Figure 2 e.g. on the roof of the dryer (1) and in the area of the Hot air duct (3) arranged.
- the air conditioning device (29) has a suitable control (33) with which the conditioning of the dry air can be changed oscillating.
- the controller (33) is preferably freely programmable. It is as electronic circuit or as a computer with one or trained and has multiple microprocessors suitable data storage, bus systems, input and Output units and interfaces for the connection with other control units, e.g. a cross-dryer machine control.
- the control (33) can also be integrated in a higher-level control or be assigned in modules.
- the controller (33) there are default values for temperature and relative humidity stored, which is related to the drying behavior the respective moldings (6) are adapted. They lay preferably in the form of gradients (35). Here there it e.g. for the temperature with a heating phase rising temperatures, a holding phase with constant temperature and a final phase with again rising temperature. With increasing drying progress in the moldings (6) the stress and Crack sensitivity, so that in the end the temperature can rise relatively quickly and to high values.
- the relative humidity shows a reverse behavior. She is relatively high at the beginning in order not to close the molding (6) drying out quickly and takes about at the end of Holding phase of the temperature quickly. Temperature and relative humidity refers to the dry air flow (14) and depend on each other.
- a certain rhythm can exist in the fluctuations. This is e.g. the case when the value changes of the controller (33) is specified as programmed variables become.
- the rhythm can be controlled by a timer (34) can be set.
- regulation can also take place, whereby the Actual values of temperature and / or humidity in the air flow (14) or on or in the molding (6) via suitable sensors be measured.
- the regulation then contains limit values for the fluctuation amplitude specified when it is reached the controller (33) switches and the air conditioning (29) controls in the opposite direction.
- Both values can be in the control (33) or the regulation individually influenced for humidity and / or temperature and be monitored. In a simplified embodiment it is also possible to only use one parameter, e.g. the Humidity, control. The other parameter changes then accordingly. As part of the scheme, one can or both parameters can be monitored as actual values.
- the oscillating Change in air conditioning throughout Drying process takes place.
- this can also be done happen in stages, e.g. only during the heating and Hold phase of the temperature.
- Stages There are other forms of Stages possible.
- the Moldings (6) around relatively thin-walled structures, e.g. Roof tiles, tiles or the like.
- the moldings (6) with the air flow (14) in the aforementioned manner blown directly, the air flow (14) transversely or obliquely to one or both broad sides of the moldings (6) is directed.
- the moldings (6) during the entire drying process blown with the air flow (14).
- the usual ones Rest periods and the rhythm of blowing are eliminated. you will be due to the oscillating conditioning of the dry air replaced.
- the Moldings (6) can be in front of the Moldings (6) have a perforated plate on at least one side (30,31) can be arranged.
- a perforated plate on at least one side (30,31) can be arranged.
- front and rear perforated plates (30.31) are in the mutual blowing of the Moldings (6) front and rear perforated plates (30.31) arranged.
