  • Patent number: 8701341
    Abstract: This invention relates to control method and apparatus of wind machine for plant frost protection, and belongs to the domain of agro-meteorological disaster monitoring and control. Existing wind machines for plant frost protection only rely on critical damage temperature or wind speed as a condition to start. If there is no thermal inversion, operation of the wind machine will aggravate freezing injury to plants. If the strength of thermal inversion is weak, the effect will be minimal. The feature of this invention is that when temperature at the plant canopy is lower than the critical damage temperature of a certain plant and temperature difference between the top and bottom of the thermal inversion layers exceeds set threshold, wind machine will start automatically. Otherwise it will remain off. The control apparatus mainly consists of sensor 5 at the top of thermal inversion layer, sensor 7 at bottom of thermal inversion layer, and controller 4.

  • Patent number: 7654035
    Abstract: A method for generating a pneumatic barrier with a device that operates in a stratified atmosphere associated with the occurrence of radiation frost. This device takes cold and dense air found close to the ground by means of an axial fan with a vertical axle that propels the air upward to an elbow that forces the airflow to make a 90° turn. The airflow discharged from the device through the outlet section forms a jet with a horizontal axis. The jet's vertical cross-section, perpendicular to its axis, has a rectangular shape and sides that grow with the distance to the outlet. The momentum transported by the jet is able to create at a certain distance from the outlet a pneumatic barrier that fits the jet's section. This pneumatic barrier faces an air mass that is colder and denser than the air transported by the jet and prevents such colder and denser air from advancing toward the device.

  • Patent number: 6391224
    Abstract: Polyvinyl alcohol and related compounds are provided that inhibit the freezing of water and water solutions. These synthetic compounds preferentially bind and inhibit ice nucleating surfaces in a manner similar to natural antifreeze proteins. The resulting inhibition allows water and water solutions to supercool without ice formation to temperatures below the thermodynamic freezing point. The freezing inhibition occurs at concentrations as small as one part per million, although concentrations up to one part per hundred are preferred. These polyvinyl alcohol additives are very useful for enhancing the performance of antifreeze formulations, biological cryopreservation solutions, and for preventing frost damage to plants and other industrial products and processes.

  • Patent number: 6257498
    Abstract: An economical and compact air handler specially configured for use in agricultural applications is provided. The agricultural air handler includes a shroud formed to surround a rotating shaft having a propeller attached to each end of the shaft. The propellers draw air through an air inlet located proximate the top of the shroud. Each propeller blows the air out of an end of the shroud. A shaft drive rotates the shaft. The shaft drive can be powered by a source outside the shroud, or a source contained within the shroud. The power source can include a hydraulic pump driven by the power take-off of a tractor. An air stream is blown from the shroud. The air stream is directed in an approximately vertically planar flow pattern to remove water ponded within the stem cup of a agricultural crop, such as cherries. The air handler can be used as a freeze protecting heat exchanger or for the application of liquid or dust formulations of agri-chemicals.

  • Patent number: 6223995
    Abstract: A device and method for cooling a vegetation covered surface, such as a golf putting green. Said method includes providing an air stream, injecting water into said air stream, and projecting the combined air/water mixture over and onto the surface to be cooled. The air/water mixture generally takes the form of a mist which is able to cool the air space directly above the ground surface, and further provides the advantage of providing cooling and moisture to the vegetation without saturating the subjacent soil. Alternately, the device may be used with only the fan portion operational, or with only the water injection operational.
