  • Patent number: 8726539
    Abstract: A gas heater with specialized controls allows an operator to deploy a single device to heat and to dry when extracting moisture from a structure. The heater has a fan in a blow thru arrangement ahead of a burner. The burner uses either natural gas or liquefied petroleum gas. The heater has air flow, fan motor, temperature, and ignition controls and sensors. The heater delivers high temperature air to the structure that hastens evaporation as the heated air absorbs great concentrations of water vapor. Then the moisture laden heated air exits the building as the heater draws in fresh air, ducts it into a structure, and pressurizes the structure. This moisture laden air then leaks from the building through select windows using the energy imparted from the fan and then exhausts the moisture to the atmosphere, drying the structure.

  • Patent number: 7182268
    Abstract: The present invention relates to a method of controlling the absolute humidity of blown air in a roasting-and-drying process and a roasting-and-drying apparatus. The method makes humidity control for air blown through malt to be proper and makes the variation in the degree of drying to be decreased in the roasting-and-drying process for producing malt. In the process for roasting and drying a malt raw material, outside air introduced toward a malt layer 10 provided by heaping the malt raw material is heated and is fed to the malt raw material as the blown air. A portion of air passing through the malt raw material as circulated air is mixed with the outside air and is fed to the malt raw material as the blown air again. The absolute humidity of the blown air fed to the malt raw material is measured using a sensor 20, and the mixing ratio of the introduced outside air and the circulated air is controlled so that the measured absolute humidity is kept at a predetermined value.

  • Patent number: 6508014
    Abstract: A method of removing water from the surface of a silicon wafer or other substrate subjected to wet processing which includes a step of water rinsing. In this method a silicon wafer whose surface includes liquid water is disposed in an atmosphere saturated with water vapor. The water vapor is removed from the surface of the silicon wafer by a stream of water-saturated gas. Upon removal of liquid water from the surface of the silicon wafer the water vapor in the water vapor saturated atmosphere is removed by evaporation.

  • Patent number: 6446357
    Abstract: A method and apparatus for controlling the drying cycle of a dryer by utilizing fuzzy logic control. Control is accomplished by first monitoring the moisture level of a clothes load in the dryer. From the monitored moisture information, variables such as the elapsed time from the start of the drying cycle to a point when no significant moisture is detected for a specified time period and the number of times higher moisture registrations occur during another specified time period are determined. Based on the determined variables, fuzzy logic is used to determine characteristics particular to the clothes load being dried, such as size of the load. Using the determined characteristics in conjunction with user settings more accurate control of the time of drying heat application, reduced drying heat application and cool down time can be accomplished.

    Abstract: A method and a device function for monitoring and/or controlling and regulating a granulation, agglomeration, instantization, coating and drying process in a fluidized layer or a moving bulk by determining the product moisture. At least during one process segment the total product moisture is measured substantially continuously over a period of seconds, in a contact-free manner using electromagnetic radiation in the high frequency or microwave range, by evaluation of the attenuation of the radiation as a measure of this total product moisture. Taking into account the product temperature, the measurement result is used to hold the total product moisture in a pre-determined range via a control circuit by changing the spray rate and/or the gas temperature and/or the volume flow.

  • Publication number: 20020038521
    Abstract: A method and an appliance are disclosed for the non-thermal drying of articles, in particular motor vehicle bodies, freshly painted with a water-based paint. The articles to be dried are subjected to dry air by forced convection in a drying tunnel and the moisture-laden air is dried in an air drying device by condensation to a specific target value of absolute residual moisture. So that fluctuations in the incidence of moisture can be leveled out with a low degree of inertia, with the high condensation performance remaining unchanged, only a fraction of the circulated air which is adapted in size, as required, is dried in the air drying device to a residual moisture markedly below the circulating-air target moisture, and the remaining untreated part of the circulated air is led back into the drier housing after being intermixed with the dried part-air stream.
