  • Patent number: 7574816
    Abstract: A drier apparatus for removing water or other liquids from various materials includes a mixer, drying chamber, separator and regenerator and a method for use of the apparatus. The material to be dried is mixed with a heated media to form a mixture which then passes through the chamber. While passing through the chamber, a comparatively cool fluid is passed counter current through the mixture so that the mixture becomes cooler and drier and the fluid becomes hotter and more saturated with moisture. The mixture is then separated into drier material and media. The media is transferred to the regenerator and heated therein by the hot fluid from the chamber and supplemental heat is supplied to bring the media to a preselected temperature for mixing with the incoming material to be dried. In a closed loop embodiment of the apparatus, the fluid is also recycled from the regenerator to the chamber and a chiller is utilized to reduce the temperature of the fluid to a preselected temperature and dew point temperature.

  • Publication number: 20080201980
    Abstract: The present invention harvests and utilizes fluidized bed drying technology and waste heat streams augmented by other available heat sources to dry feedstock or fuel. This method is useful in many industries, including coal-fired power plants. Coal is dried using the present invention before it goes to coal pulverizers and on to the furnace/boiler arrangement to improve boiler efficiency and reduce emissions. This is all completed in a low-temperature, open-air system. Also included is an apparatus for segregating particulate by density and/or size including a fluidizing bed having a particulate receiving inlet for receiving particulate to be fluidized. This is useful for segregating contaminants like sulfur and mercury from the product stream.

  • Patent number: 7316080
    Abstract: A method and apparatus for reducing fuel consumption in conveyor ovens by creating a barrier to the infiltration of heated air from a heating section of the oven into a cooling section of the oven thereby reducing the loss of heated air and reducing consumption of fuel otherwise required to maintain the selected oven temperature. The barrier is formed by directing a stream of pressurized air into a transition section between the heating and cooling sections of the oven.

  • Patent number: 6519869
    Abstract: A method and an apparatus for drying semiconductor wafers by using an IPA drying apparatus. The present invention uses a vapor generator to generate an IPA vapor. The IPA vapor is generated and saved in a closed surrounding and then transferred in a porous hollow plate in the dryer tank by using a quartz pipe. The IPA vapor is diffused evenly from the porous hollow plate. Furthermore, the present invention increases the safety of the process and can easily control the input amount of the IPA vapor.

  • Patent number: 6505417
    Abstract: In a method for controlling airflow on a backside of a semiconductor wafer during spin processing, a wafer backing plate is first disposed below a semiconductor wafer. Air is then supplied to the volume defined by the wafer backing plate and the semiconductor wafer. The air may be supplied to the volume through a hollow core spindle, a rotary union, or apertures in the wafer backing plate. The separation distance between the wafer and the wafer backing plate and the flow rate of air supplied to the volume may be controlled to avoid any substantial recirculation of contaminated air into the volume. In addition to serving as one of the boundaries that define the volume, the wafer backing plate reduces particle recontamination on the backside of the wafer by preventing particles from contacting the backside of the wafer during spin processing.

  • Patent number: 6421931
    Abstract: In the present method of drying iron ore pellets, e.g., magnetite pellets, moisture-containing iron ore pellets are formed into a bed comprising a multiplicity of the pellets. A current of drying gas is forced through the bed of pellets to at least partially dry some of the pellets. At least one jet of a drying gas that contains added oxygen is directed onto the bed of pellets so to impinge upon a surface of the pellet bed thereby providing kinetic energy for directing oxygen including the added oxygen into the pellets so as to enhance the conversion of magnetite to hematite. Moisture can be added to heated air that is then blown through jet nozzles onto the pellet bed or circulated back to an earlier drying stage and passed through the bed.

  • Patent number: 6230421
    Abstract: A method and apparatus for drying grain in which a plurality of conveyors are mounted one above the other. The discharge end of one conveyor feeds the input end of the next lower conveyor. The conveyors have a porous top surface and are vibrated to move the grain. Warm air is conveyed beneath the top conveyor and every other conveyor thereafter. Cool air is conveyed beneath the conveyor beneath the top conveyor and every other conveyor thereafter. The warm and cool air passes through the porous top surfaces of the conveyors. Thus the conveyors alternately heat and cool the grain to remove moisture to the desired level. The apparatus can be free standing or mounted as part of a combine or harvester.
