Problems solved by technology

Utilizing conventional dryers, these flexible printed circuit boards or printed circuit films cannot be dried to the desired degree of effectiveness because the treated item flexes or bends and through the stress created on the treated item— —The pressure is generated by the driving drying medium driven by the nozzle —and pressed on the nozzle or other parts
However, if the pressure is reduced appropriately, the required drying time is considerably extended

Embodiment Construction

[0031] figure 1 The structure and interaction of the different components of the dryer according to the invention are schematically shown. The dryer includes a casing 6 divided into two parts, and compressed air fans 16, 17 arranged at the lower part of the casing 6. The fans 16, 17 independently supply compressed air to nozzles 4 and 5 called pressure nozzles. The compressed air is used as a drying medium in this case. The nozzles 4 and 5 are located in the upper part of the housing 6. The nozzle 4 is arranged above the transfer path, which extends from the inlet 7 to the outlet 31 of the housing 6, and the nozzle 5 is arranged below the transfer path. In each case, the nozzle 4 and the nozzle 5 are placed opposite to each other in such a way that their outlet holes face each other. In this embodiment, two pairs of nozzles 4, 5 are shown; however, there may be more pairs or only one pair of nozzles.

[0032] Located in the lower part of the housing 6 are adjustment devices 18...

Abstract

The invention relates to a device and to a corresponding method which is used to dry a treated product (1). Said device comprises transport means (3) which are used to transport the treated product (1) along a conveyor belt. Gas outlet devices (4, 5) which are disposed in an opposite manner are arranged above the conveyor belt. A gaseous drying medium is guided by blowing means to the gas outletsin a separate manner via supply pipes (8, 9). Pressure allocated to a respective gas outlet device (4, 5) is detected and a gas flow associated with the gas outlet device (4, 5) is controlled by control means according to said pressure.

Description

Technical field [0001] The present invention relates to a method and device for drying processed items. More specifically, the method and device according to the present invention are used to quickly, gently and uniformly dry, for example, processed plate-shaped objects-which are preferably processed in electroplating or etching equipment. Background technique [0002] In many wet chemical, electrolytic, or other coating processes, it is necessary to dry the items that have been processed and coated on as the final working step of the process. For this purpose, dryers including a housing are often used, into which the processed items are continuously conveyed, and after the drying process they are conveyed out of the housing. Generally, a gas drying medium such as air is used for drying. In order to improve the drying effect, the gas drying medium is heated—for example, by a heat exchanger or a heating cylinder. In this case, a heat insulating device is generally provided outsi...
