According to the method, the temperature difference between the inside temperature of the heating oven and, correspondingly, the inside temperature of the wood is maintained at a maximum of 10° C., after the level of moisture content of the piece of wood has reached the fibre saturation point of the wood. A small temperature difference such as this is maintained when the temperature is further increased until a level of moisture content is reached at which the strength properties of the piece of wood are at their best. By means of the solution it is possible to considerably reduce the formation of internal cracks in heat treated wood.

  • Patent number: 7325331
    Abstract: The invention relates to a method for drying a fibre-based pulp web (2), and to a drying box (1) used in the method. According to the invention, the drying box (1) contains drying zones (9a-9e), to each one of which hot drying air can be blown independently so that the web can be dried in the various zones at different temperatures. The temperature of the first zone (9a) can thus be lower than that of one or more subsequent zones (9b-9e) to prevent the water in the incoming wet web from boiling. The last zone in the drying box (1) can be a separate cooling zone (11), wherein the web is cooled by indoor air from outside the box. The temperatures can be adjusted by adjusting, with the aid of valves (8), the pressure of the steam, which heats the drying air that is fed into the various zones (9a-9e), on the basis of the temperatures measured by the sensors (23) for the various zones and of the basis weight and moisture measurements carried out on the web (2) that goes into the box (1) and comes out of the box.

    Abstract: The objective of the present invention is an accelerated drying process for wood, capable of use with all species and of maintaining the quality of the dried wood intact, in which the temperature of the system is kept within the glass transition temperature range, for an appropriate period so as to attain the intended humidity ratio of the wood. It relates to an accelerated drying process for wood based on the rheological properties (hygro-thermalviscoelastic) of the latter, where the glass transition temperature of lignin is used as a relaxant or neutralization agent for the residual growth stress of trees, as well as those from the drying process. The process is controlled by monitoring the temperatures of the wood through the use of thermocouples placed along the length of the pieces. Furthermore, the use of the process of the present invention provides a significant reduction in the drying time and a reduction of the defects because molecular fluidity is maintained.

    Abstract: A process for drying a polymeric material present on a substrate is provided. Temperatures of the polymeric material is measured and the ambient temperature in the vicinity of the substrate. A temperature of the substrate is also measured. A variation in the measured ambient temperature is detected. The substrate temperature, polymeric temperature, ambient temperature or a substrate drying spin speed is adjusted in response to the detected variation in the measured ambient temperature.

  • Publication number: 20010003874
    Abstract: Moisture content of material such as thermoplastic pellets (80) in a hopper (30) is controlled by supplying dehumidified air from a dessicant bed (90) to the hopper (30) and returning air from the hopper (30) to the dessicant bed (90). A dew point sensor (10) in the return air path determines the moisture content of the material (80) in the hopper (30), and when the dew point drops to a pre-set level, a diverter (134) causes the return air flow to bypass the dessicant bed (90) and to be re-supplied to the hopper (30) without dehumidification. Two dessicant beds are provided, one of which is on-process while the dessicant in the other is regenerated.

  • Patent number: 6216364
    Abstract: A drying apparatus for washed objects is capable of drying the objects in a reduced period of time, effectively preventing contamination of the objects during drying thereof, and attaining energy saving and a reduction in consumption of chemicals used. Mist of an organic solvent is generated by means of an ultrasonic wave in an organic solvent mist generating tank and the objects are immersed in a pure water tank, the pure water tank and organic solvent mist generating tank are then operated to communicate with each other to discharge pure water and place the objects in an atmosphere of the organic solvent mist, and then nitrogen gas is fed to the pure water tank to purge the organic solvent mist with the nitrogen gas.

  • Patent number: 6145219
    Abstract: A room for bringing products to a specific desired temperature. The room is provided with a heat or cold source and detectors for measuring temperature in the room at a plurality of locations. A number of fans are positioned in the room in the region of a wall, floor or ceiling. In a prepared embodiment, the fans are displacable in a line along a wall, floor or ceiling of the room. In another embodiment, the fans are placed at a regular distance above one another. The line of fans may be displaced backwards and forwards along the wall from one corner of the room to the other. There is also provided a method of defrosting products, such as meat.

  • Patent number: 6067728
    Abstract: An apparatus and method for drying a microelectronic structure on wafer substrate using supercritical phase gas techniques and a unique pressure vessel locking mechanism. There is lid and a base with an open cavity to contain at least one microelectronic structure on wafer substrate. Clamping the lid to the base uses locking clamp rings with open jaws large to partially enclose the edge of the vessel. The clamp rings are supported symmetrically about the sides of the vessel. The rings are adjusted between an open position where the rings are clear of the vessel and a locking position where the jaws partially enclose the vessel. The jaws and the vessel share a tapered cam plate and roller system configured to bring the rings into vertically compressive locking engagement on the pressure vessel when the rings are moved into locking position. Mechanical interlocks provide security against back pressure opening the rings.

  • Patent number: 5603168
    Abstract: A method and apparatus for operating a dryer used to reduce the moisture content of sheet material such as a jet veneer dryer. A drying chamber is provided and includes a plurality of individual, juxtaposed drying sections. Each drying section circulates air in a path substantially transverse to the path of movement through the dryer. A single point exhaust system extracts the exhaust from the first drying section. A wet seal section located at the input end of the dryer includes an exhaust passage through which a gas sample is drawn by a sampling fan. Gases within the wet seal section are a combination of ambient air drawn through restricted passages at the entry to the wet seal section and exhaust gas that bleeds into the wet seal section from the drying chamber. A controller monitors the temperature of the sampled gases and ambient air and adjusts the rate of exhaust flow from the main exhaust system as a function of the temperature differential.

  • Patent number: 5526582
    Abstract: A method and apparatus are provided for operating a pressurized reactor system in order to precisely control the temperature within a pressure vessel in order to minimize condensation of corrosive materials from gases on the surfaces of the pressure vessel or contained circulating fluidized bed reactor, and to prevent the temperature of the components from reaching a detrimentally high level, while at the same time allowing quick heating of the pressure vessel interior volume during start-up. Superatmospheric pressure gas is introduced from the first conduit into the fluidized bed reactor and heat derived reactions such as combustion and gassification are maintained in the reactor. Gas is exhausted from the reactor and pressure vessel through a second conduit.
