A device for controlling the temperature of workpieces, in particular for drying vehicle bodies, having a housing, a temperature-controlling tunnel accommodated in the housing, and a temperature-controlling system for controlling the temperature of workpieces. The temperature-controlling system includes a full-space temperature-controlling device which can control the temperature of a workpiece as a whole, and a local temperature-controlling device which can control the temperature of locally delimited regions of the workpiece and which comprises multiple temperature-controlling units that can be activated and actuated independently of one another for this purpose. The full-space temperature-controlling device and the local temperature-controlling device are provided in the temperature-controlling tunnel such that a workpiece at least within an active section in the temperature-controlling tunnel can be under the influence of both the full-space temperature-controlling device as well as the local temperature-controlling device. A system and a method for controlling the temperature of workpieces are additionally provided.

A lifting facility for a workpiece is provided in a drying furnace for drying the workpiece, and comprises: a drop lift that conveys the workpiece so as to raise and lower the workpiece between one of a carrying-in position at which the workpiece is carried in the drying furnace and a carrying-out position at which the workpiece is carried out from the drying furnace and a high-temperature zone which is formed above the carrying-in position and the carrying-out position and in which the workpiece is dried; and a strut that supports the drop lift so as to raise and lower the drop lift. The strut is extended to the high-temperature zone in the drying furnace.

Method for harvesting and processing water hyacinths, characterized in that the following steps are performed: a) the water hyacinths growing in an aquatic medium are cut; b) the water hyacinths are collected on board a barge at berth (1); c) the collected water hyacinths are transferred onto draining racks (2) near the quayside; d) the drained hyacinths are washed with clean water; e) the washed water hyacinths are drained on vibrating belts (7) in order to remove some of the excess water; f) the water hyacinths are dried on a dryer (8) at a temperature of between 50 and 100 C. for 5 to 17 h; g) the water hyacinths and their seeds are steam-sterilised at a temperature of between 80 and 100 C. in order to sterilise them; h) the sterilised water hyacinths and seeds are ground in order to make profitable use thereof.

A horizontal multistage press apparatus 1 (multistage drying apparatus) includes conveyance paths R1 to R4 (first to fourth conveyance paths) in which the veneer sheet W1 (sheet material to be treated) is carried out in a standing state. The conveyance path R1 is positioned over between the loader device 10 and the hot press device 20, the conveyance path R2 is positioned over between the hot press device 20 and the open transpiration device 40, the conveyance path R3 is positioned over between the open transpiration device 40 and the temperature control press device 50, and the conveyance path R4 is positioned over between the temperature control press device 50 and the unloader device 60. The conveyance paths R1 to R4 are arranged in a straight line in plan view.

An industrial oven includes an oven chamber configured to receive a plurality of workpieces for drying or curing. A heater box of the oven has a heating element therein operable to heat air for delivery to the oven chamber. A circulation system of the oven is operable to force hot air from the heater box into the oven chamber. A VOC oxidation catalyst is provided in the circulation system.

Embodiments provide a unidirectional multi-path kiln with two or more chambers and generally parallel flow paths extending through the kiln, on opposite sides, from charge entry portals at a first end of the kiln to charge exit portals at a second end of the kiln. Moist heated air flowing from the second heated chamber is received in the first chamber and circulated around the lumber charges with one or more fans. The lumber charges proceed in the same direction on the flow paths through the heated second chamber, which may be an existing kiln. Charge exit portals at the distal end of the kiln and/or intermediate charge portals between the second chamber and a third chamber may be provided with insulating members configured to reduce airflow from the second chamber through the charge exit portals.

A paint baking oven bakes a wet coating film applied to a vehicle body while conveying the vehicle body. The vehicle body has a main shell body to which side doors are attached via hinges. The topcoat paint baking oven includes a oven body and a hot air supplier that supplies hot air into the oven body. The oven body is configured to include a first oven body and a second oven body. The first oven body has a side-to-side width corresponding to a body width of the vehicle body in a state of closing the side doors. The second oven body has a width wider than the side-to-side width of the first oven body. The width of the second oven body corresponds to a body width of the vehicle body in a state of opening the side doors.
