    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.

  • Publication number: 20120144694
    Abstract: A laundry dryer includes a rotatable drum and an air delivery system. The air delivery system can include a reversible blower that provides air at a first flow rate when operated in a first direction and provides air at a second lower flow rate when operated in an opposite second direction. The drum can be a reversibly rotatable drum that is rotatable in a first and an opposite second direction, and the dryer can include a drive motor that both rotates the drum and operates the blower. Drum and blower reversal may be controlled to optimize drying efficiency and also reduce stress on the drive system. A moisture delivery system can provide moisture (e.g., water mist or steam) into the drum while air is being provided at the lower second flow rate, and during drum rotation (tumbling).

    Abstract: A grain dryer control system uses the grain dryer discharge temperature to account for moisture reduction in the grain as it cools after discharge from the dryer. The control system includes moisture and temperature sensors and a means to control the discharge of grain from the grain dryer. Given a grain discharge temperature, a control temperature and a moisture reduction factor as a function of temperature, the control system calculates an expected moisture reduction in the grain as the grain cools. Grain is discharged from the dryer when the target moisture content after cooling added to the expected moisture reduction in the grain as the grain cools meets the measured grain moisture content in the dryer.

  • Patent number: 5551168
    Abstract: A continuous-flow, slow grain cooling process including the charging of hot, partially dried grain from a heated-air grain dryer into the top of a grain container in an even layer. The downward flow of grain through the grain container is regulated at a rate that allows the grain to remain in a top steeping zone for from four to twelve hours. After the initially charged grain is held at the steeping temperature for a predetermined steeping time, a controlled upward flow of ambient air is provided to cool the grain in a bottom cooling zone. The air flow is provided at a rate that allows grain to remain in the cooling zone until it is cooled close to the ambient air temperature, but the upward flow is controlled such that it will not cool any grain until it has been properly steeped. Cooled dry grain from a layer near the bottom is then discharged from the bottom of the grain container.

    Abstract: A continuous-flow grain steeping and slow grain cooling process and apparatus. The continuous charging of hot, partially dried grain from a heated-air dryer into the top of a grain container in a layer of approximately uniform thickness is accomplished by use of grain spreading equipment. The downward flow of grain through the grain container is regulated by thermostatically controlled sweep and discharge augers located in the bottom of the bin. The grain flows at a rate that allows the grain to remain in a top steeping zone for a predetermined period of time, typically from four to twelve hours. After the initially charged grain is held at the steeping temperature for a predetermined steeping time, a continuous upward flow of ambient air is provided by a fan to cool the grain in a bottom cooling zone. The air flow is controlled by a thermostat to provide air flow at a rate that allows grain to remain in the cooling zone for a predetermined cooling time which is dependent on the airflow rate in cfm/bu.
