Book excerpt: Drying Hardwood Lumber focuses on common methods for drying lumber of different thickness, with minimal drying defects, for high quality applications. This manual also includes predrying treatments that, when part of an overall quality-oriented drying system, reduce defects and improve drying quality, especially of oak lumber. Special attention is given to drying white wood, such as hard maple and ash, without sticker shadow or other discoloration. Several special drying methods, such as solar drying, are described, and proper techniques for storing dried lumber are discussed. Suggestions are provided for ways to economize on drying costs by reducing drying time and energy demands when feasible. Each chapter is accompanied by a list of references. Some references are cited in the chapter; others are listed as additional sources of information.
Download or read book Dry Kiln Schedules for Commercial Woods Temperate and Tropical written by R. Sidney Boone and published by . This book was released on 1988 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contains suggested dry kiln schedules for over 500 commercial woods, both temperate and tropical. The schedules are written out for easy reference and use. The majority of the schedules are from the world literature with emphasis on U.S., Canadian, and British publications. Revised schedules are suggested for western U.S. and Canadian softwoods and U.S. southern pines. Included are conventional and elevated temperatures for U.S. and Canadian species, Latin American woods, Asian and Oceanian woods, African woods, and European woods. Also included are high temperature schedules for U.S. and Canadian species and tables of assembled dry kiln schedules.

Download or read book Operation and Cost of a Small Dehumidification Dry Kiln written by Richard D. Bergman and published by . This book was released on 2008 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Obtaining small quantities of custom kiln-dried lumber can be an expensive process for an individual woodworker. Building and operating a small kiln capable of drying custom cuts of lumber (such as slabs, bowl blanks) gives woodworkers another option. Our approach was to build and operate a small dehumidification dry kiln. The four charges of lumber ranged from 600 to 700 board feet (bf), and a woodworker with no dry-kiln experience operated the kiln. The first charge of mixed air-dried 4/4 hardwoods and softwoods was kiln-dried from 18.4% to 7.3% moisture content (MC) in 15 days with no casehardening. The second charge of 5/4 black cherry lumber was kiln-dried from 47.5% to 6.8% MC in 27 days with no casehardening, and the third charge of 4/4 northern red oak lumber was kiln-dried from 82.9% to 6.1% MC in 45 days and to 5.2% MC in 50 days with severe casehardening relieved by conditioning. A fourth charge of 300 bf 4/4 northern red oak, 200 bf of 4/4 shagbark hickory, and 100 bf of mixed 4/4 box elder and 4/4 black cherry was kiln-dried from 69.7% to 8.5% MC in 29 days with casehardening only in the northern red oak, and that was relieved by conditioning. We found that greater control of the dehumidifier operation earlier in the kiln schedule to maintain the safe drying rate would decrease the severity of casehardening when drying green northern red oak. New building materials, which are most of the initial cost, could be replaced by reused lumber. Drying small amounts of lumber using a dehumidification kiln is a suitable option for woodworkers even with limited knowledge of kilns.

Download or read book FPL Design for Lumber Dry Kiln Using Solar wood Energy in Tropical Latitudes written by John L. Tschernitz and published by . This book was released on 1985 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developing countries with a timber resource that can be manufactured into finished products either for local use or export often lack the capital to build high-cost dry kilns. Many of these countries are in the tropics where solar radiation and ambient temperatures are high. The low-cost solar/wood energy lumber dry kiln described in this report was designed and tested by the Forest Products Laboratory (FPL) for such countries where solar dry kilns can be built and operated at low cost. The FPL design is for a 6,000-fbm capacity kiln having an insulated drying compartment, an external horizontal solar collector, and a furnace room containing a wood burner. Capacities larger or smaller than 6,000 fbm are also possible. This design allows collector and wood burner sizing to match the energy demands of the dryer. The design also incorporates low-cost controls that allow unattended drying when operated as a solar-only dryer. Manual firing is necessary when the wood-burning system is supplying the energy. This kiln design is the final, commercial-size version established after years of testing several 1,000-fbm capacity prototypes. In December 1984 a kiln of this design was built in Sri Lanka at a factory that manufactures furniture and laminated beams from rubber and coconut wood.

Robert Rickett's pioneering dissertation is published here for the first time, with additional material from Mark McKerracher which sets the work within the context of more recent studies.
Download or read book Industrial Drying Systems written by J E 'Ed' Smith and published by Springer Nature. This book was released on 2023-06-23 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book stands as a manual and ready reference for the range of professionals involved in industrial drying. It addresses problems connected with most industrial drying systems, too often designed by those with limited formal engineering training in an environment of minimal regulatory oversight. The author explains how many existing drying systems are dangerous and pose fire hazards, create unhealthy working conditions, are highly energy inefficient, and have very little to no primary modeling of key process variables. Equipping readers with the necessary competencies to contend with issues in conducting studies, developing new designs; manufacturing, installing, and servicing industrial drying systems, this volume is ideal for engineers, OEMS, contractors, service technicians, scientists; agriculture, food, wood products manufacturers; and insurance underwriters.
