  • Patent number: 9004079
    Abstract: Disclosed is a substrate processing apparatus capable of drying a substrate to be processed while suppressing the pattern collapse or the occurrence of contamination. A substrate is held in a liquid bath while being immersed in a liquid, and the liquid bath is disposed in a processing space of a processing vessel. A processing of drying the substrate is performed by replacing the liquid in the liquid bath with a supercritical-state fluid. A predetermined mechanism moves liquid bath between a processing location in the processing case and a stand-by location outside the processing case. A heater installed in the processing case changes the fluid to a supercritical state or maintains the supercritical state while cooling mechanisms cool down the liquid bath moved to the stand-by location outside the processing vessel.

    Abstract: An apparatus and method for treating a moving substrate of indefinite length. The apparatus has a control surface positioned in close proximity to a surface of the substrate to define a control gap between the substrate and the control surface. A first chamber is positioned near the control surface, with the first chamber having a gas introduction device. A second chamber is positioned near the control surface, the second chamber having a gas withdrawal device. The control surface and the chambers together define a region wherein the adjacent gas phases possess an amount of mass. Upon inducement of at least a portion of the mass within the region, the mass flow is controlled to significantly reduce dilution of the gas phase component in the adjacent gas phase. This is accomplished through the introduction of a controlled gas stream thereby reducing the flow of an uncontrolled ambient gas stream due to pressure gradients in the system.

  • Publication number: 20100107438
    Abstract: Humid waste air is produced in heated laundry machines. This humid waste air has a still relatively high temperature. In order for the energy contained in the humid waste air to be recovered, at least in part, the humid waste air is directed through a heat exchanger (12). Condensate is produced in the heat exchanger (12), and it has proven difficult, in the case of known heat exchangers (12), for this condensate to be directed away. Moreover, the humid waste air contains accompanying substances, for example fluff from the treated laundry. These accompanying substances are deposited in known heat exchangers (12), which adversely affect the efficiency of the heat exchanger (12) over time. The invention makes provision for the heat exchanger (12) to be equipped with upright heat-exchanger plates (13), from which the condensate can run off. The condensate can then be discharged in a specific manner out of the heat exchanger (12).

  • Patent number: 7707741
    Abstract: A system and method for drying cavities loaded with high level waste (“HLW”) is devised. The invention utilizes a non-intrusive procedure that is based on monitoring the dew point temperature of a non-reactive gas that is circulated through the cavity. In one aspect, the invention is a method comprising: a) flowing a non-reactive gas through the cavity; b) repetitively measuring the dew point temperature of the non-reactive gas exiting the cavity; and c) upon the dew point temperature of the non-reactive gas exiting the cavity reaching and remaining below a predetermined dew point temperature for a predetermined time, discontinuing the flow of the non-reactive gas and sealing the cavity. In another aspect, the invention is a system designed to carry out the method.

  • Patent number: 7654011
    Abstract: A method and apparatus are provided for reducing the VOC, CO, and, alternatively, the NOx content of dryer offgas that is discharged into the atmosphere from a moist organic product drying process using thermal oxidizing apparatus that includes a burner, furnace, mixing chamber, thermal oxidizer, tempering chamber, and an indirect gas-to-gas heat exchanger. The dryer offgas is separated into two portions, with a larger portion being preheated by indirect heat exchange with the hot gaseous output from the thermal oxidizer. The non-preheated portion is directed to the burner in the function of flue gas recycle for NOx control. The preheated portion is separated into two portions, with one portion being directed to the furnace/mixing chamber of the thermal oxidizing apparatus. The other portion of the preheated offgas is recycled to the hot gas inlet of the dryer and serves the function of dryer heat transfer media.

  • Publication number: 20090293302
    Abstract: An artwork drying cabinet includes a housing that defines an interior drying compartment. A plurality of removable shelves are provided in parallel spaced relation within the compartment. A hinged door provides access to the compartment for purposes of loading and removing shelves with artwork. The door includes a vent to exhaust moisture laden air from the compartment. A blower and heating element are provided to supply a heated current of air to the compartment. A shroud couples the blower and heating element to the cabinet and directs the flow of heated air into the cabinet. The blower sends the current of air over the heating element through a diffuser comprising a v-shaped baffle with a central elongated opening along the vertex. Controls are provided to regulate air speed and temperature. An optional timer controls the duration of a drying cycle. The diffuser evenly distributes parallel laminar streams of heated air above and below each shelf.
