  • Patent number: 7020980
    Abstract: A method of treating a waste stream comprises a vacuum treatment to promote disintegration of the waste material by “flash vapor” production, causing a swiftly vaporizing fraction inside the material to literally explode or shred apart the matrix of the material as a whole. A main processor operates at a level of vacuum that determines a given boiling temperature for a vaporizing fraction, and one which lower than the fraction's boiling temperature for the local vicinity's barometric pressure (eg., atmospheric pressure). The input stream is pre-heated to above the given boiling temperature for that fraction as determined by the main processor's vacuum level without, however, going over the boiling temperature for the local barometric pressure. It is then introduced into the vacuum of the main processor whereby a minor percentage of the vaporizing fraction flashes into vapor, and this presumptively promotes destruction and/or disintegration of the material.

  • Patent number: 6966949
    Abstract: In drying a coating liquid such as a resist applied to a substrate under reduced pressure, a coating film in a peripheral portion tends to lose good shape regardless of duration of a drying period, and it is difficult to set an appropriate exhaust flow rate. After the substrate is loaded in an airtight container, a pressure is reduced from atmospheric pressure to a pressure slightly higher than the vapor pressure of a solvent, for example. Then, the solvent actively evaporates from the coating liquid. Here, evacuation is performed initially based on a first flow rate set value Q1, and thereafter, it is performed based on a second flow rate set value larger than Q1. Rounding of the surface in the peripheral portion is corrected by evacuation based on Q1, and more active evaporation of a solvent component is attained by switching to Q2.

  • Patent number: 6865821
    Abstract: A lumber drying kiln employs outside air pressure uses a flexible collapsing bag or cover alone or in combination with walls. The collapsing bag seals against a base to maintain the vacuum. The air pressure against the flexible top keeps the lumber layers from warping or cupping during drying. The lumber stack has alternating layers of hot plates or stickers separating layers of lumber. A bag having an open bottom and made of nylon-reinforced rubber or other strong flexible material is placed over the wood and sealed to the stainless steel platform. A vacuum pump is connected with the bag by means of a manifold and operated to remove air from the enclosed lumber stack, the vacuum strengthening the seal between the base and the bottom of the bag. This chamber design is easily scaled up or down to provide a desired drying capacity.
