    Effect of environment during curing on the quality of burley tobacco: II. Effect of high humidity curing on support price

    WALTON L.R.; HENSON W.H., Jr; BUNN J.M.
    USDA, ARS, USA; University of Kentucky, Lexington, Kentucky USA
    An experiment was designed to determine the quality deterioration of burley tobacco due to low drying rate, i.e., excessive humidity during the cure. Support price was used as an indication of quality. The period of exposure to slow drying conditions...

    Measurements of plant parameters as indicators of harvest ability of burley tobacco

    HENSON W.H., Jr; BARFIELD B.J.; BUNN J.M.
    Agricultural Engineering, USDA, ARS, USA; Department Agricultural Engineering, University of Kentucky, Lexington, Kentucky USA
    Studies were made on the brittleness index (harvestability) of tobacco as related to plant-water potential, critical radius of curvature, and moisture content. Each of these parameters offers a possibility for predicting harvestability and for...

    Effect of environment during curing on the quality of burley tobacco: I. Effect of low humidity curing on support price

    WALTON L.R.; HENSON W.H., Jr
    USDA, ARS, University of Kentucky, Lexington, Kentucky USA
    An experiment was designed to determine the quality deterioration of burley tobacco due to excessive drying rate. Support price was used as an indication of quality. The period of exposure to excessive drying conditions varied in length and stage of...

    Effects of curing techniques on the hygroscopic properties of primed Burley tobacco

    BUNN J.M.; HENSON W.H., Jr; SMITH E.M.
    Agricultural Engineering Department, University of Kentucky, Lexington, Kentucky USA
    A discussion has been presented of investigations into hygroscopic responses associated with controlled curing of primed burley tobacco. The investigations centered around the adaptation of a commercial bulk curing facility for curing primed burley...

    The influence of leaf maturity and other factors on the drying rate of bright-leaf tobacco

    HENSON W.H., Jr; JOHNSON W.H.; HASSLER F.J.
    Harvesting and Farm Processing Research Branch, USDA, Agricultural Engineering Department, University of Kentucky, Lexington, Kentucky; and Agricultural Engineering Department, North Carolina State College, Raleigh, North Carolina USA
    The investigation was concerned with the measurement of drying rates of flue-cured tobacco at different levels of leaf maturity and under a drying condition equivalent to that employed in the early phase of the curing process. Leaves were selected at...

    Certain dielectric and physical properties of intact tobacco leaves

    HENSON W.H., Jr; HASSLER F.J.
    Harvesting and Farm Processing Research Branch, USDA, Agricultural Engineering Department, University of Kentucky, Lexington, Kentucky; and Agricultural Engineering Department, North Carolina State College, Raleigh, North Carolina USA
    Dielectric measurements of tobacco indicated a broad frequency range over which dispersion of the dielectric constant occurred. A mathematical model for the dielectric behavior of the intact tobacco leaf was taken as a modified Debye model. By using...

    Bulk curing of bright leaf tobacco

    JOHNSON W.H.; HENSON W.H., Jr; HASSLER F.J.; WATKINS R.W.
    Agricultural Engineering Department, North Carolina State College, Raleigh, North Carolina USA; Farm Electrification Research Branch, AERD, ARS, United States Department of Agriculture, Agricultural Engineering Department, North Carolina State College USA
    This paper describes the research and development of a curing operation which is more compatible with mechanization of bright-leaf tobacco than conventional curing. The feasibility of bulk curing was well established by laboratory studies during...

    Some determinations pertinent to removal of midrib from bright-leaf tobacco during curing operations

    JOHNSON W.H.; HASSLER F.J.; HENSON W.H., Jr
    Agricultural Engineering Department, North Carolina State College and Farm Electrification Section, U.S. Department of Agriculture USA
    Edge effects from midrib removal by cutting and stripping were negligible when the tobacco was yellowed in an environment of low drying potential of 96 per cent relative humidity. High drying conditions of 82 per .cent relative humidity amplified...
