Checking was influenced b drying conditions. This influence was greatest before average moisture content reached 20 per cent, but tension in surface layers caused checking even below this point.
Neither high initial dry-bulb temperature nor initial conditions of high equilibrium moisture content were conducive to checking.
High temperature and high...
Four charges of S-inch paper roll plugs of Oregon maple were kiln-dried at various temperatures and humidities. The charge with the most desirable combination of short drying time and low degrade was dried to 12 per cent moisture content in lit hours, using a dry-bulb temperature of 160 degrees F...
The Oregon Forest Products Laboratory was asked in July 1953 by the Oregon Alder and Maple Company, Willamina, to work on the problem of dark stain which developed at sticker crossings in air-drying red alder (Alnus rubra, Bong.) during the summer months.
Previous experience at the Oregon Alder and Maple...
A study has been made of the interrelations between certain of the physical and biochemical changes in three varieties of pears during storage and ripening. The metabolic changes which occurred in the fruit during cold temperature storage were found to influence with development of certain characteristics associated with dessert quality...
