Abstract: A high efficiency triple pass tunnel finisher includes an articulated spraying function for allowing steam to effectively penetrate a garment. The tunnel finisher can be used for the laundering of shirts, pants, and jackets. The tunnel finisher includes hot air chambers and a steam chamber that can include two rows of steam injectors located at a 45° angle in relation to the walls of the module. The steam chamber has a lower pressure than the hot air chambers, creating an air pressure differential. The hot air chambers are positively pressurized, preventing the relatively cooler air of the steam chamber from entering the chamber. The pressurization prevents heat loss, allowing the finisher to be more efficient, while increasing the temperature at which the garments exit the steam chamber. This leads to faster drying times, less garment wrinkling, and reduced dwell time for a garment with a high quality appearance.

Abstract: Modern drying units for gypsum plaster board have a feed device, comprising several roller feed units (1) arranged in levels one above the other. The drying section is generally divided into several zones (3 to 7), in particular three longitudinally ventilated zones (4 to 6), being two high temperature zones (4, 5) and a subsequent low temperature zone (6). Due to the high production capacity of the upline production plant and the necessarily long residence time, drying units are very long. According to the invention, black boards (19) are arranged above and below the individual roller feed units (1) in the high temperature zones (4, 5), which extend across the width of the roller feed units (1). The boards (19) are heated exclusively by means of the flowing drying air to an elevated temperature, and transmit additional heat to the through-flowing gypsum plaster board (16) by radiation. It is possible to reduce the length of the drying unit due to the increased heat transfer coefficient.

Abstract: A photosensitive material is dried by radiating heat from a guide plate, having high emissivity, which is disposed along a conveying path and is heated by a ceramic heater. Further, the photosensitive material is dried by a warm air, which is heated by a heater, blown onto the photosensitive material from nozzles. In the drying, because the warm air is also heated by the heated guide plate, the warm air can be risen to a predetermined temperature efficiently. Accordingly, because transferring the radiating heat and the blowing the warm air are performed at a same position (a same member), the drying can be performed efficiently without enlarging the device.

Abstract: Trays are provided with identical vertical spacers which enable the trays to be stacked on top of each other in a centered way, with a suitable or appropriate spacing between them, and enable the various adjacent stacks of trays to be raised and lowered in steps, by an elevating and lowering system which acts only on the bottom tray of each stack. The sides of the stacks of trays of the kiln are thus free and can be engaged by conveyors for the translation of the trays between the stacks, both in a normal operating cycle and in a short operating cycle. However, the lower translation conveyors, which transfer the trays from the stack with an unloading station to that with a loading station, are positioned in the conventional way, i.e., under the stacks of trays and transversely with respect to the trays.

Abstract: On drying pasty materials, particularly sewage sludge, the material is compacted in an intermediate drying stage with a dry fraction of 60 to 80%, so that relatively low energy costs are required. The conveying of the material takes place both during pre-drying and after leaving the compactor on one or two air-permeable conveyor belts (3, 4) succeeding one another in the conveying direction and which are enclosed in a common housing (2). Thus, drying before and after compacting is performed under identical method conditions, so that it is possible to produce a simple and therefore inexpensive installation for performing the method. The finished product has advantageous characteristics with regards to density and abrasion resistance, so that dust production is avoided during subsequent handling.

Abstract: In known rack dryers, the drying effect is weaker in the outer area on the side of the air intake into the pipe chambers than in the other areas. Said weaker drying effect is caused by turbulence in this area, which leads to a drop in the static pressure. The aim of the invention is to provide a dryer which ensures even drying of the goods across the entire width, even in the problem areas. The rack dryer is equipped with conductive bodies (20, 26) which are located on the partition wall (5) and which streamline the current in the area of the air intake into the pipe chambers in such a way, that a predominantly even static pressure prevails throughout the entire pipe chamber. The invention can be used for drying sandwich-type plaster board or wood veneer.
