Operation and Cost of a Small Dehumidification Dry Kiln

Book Description
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.

Book Description
A spreadsheet-based model, LSY (Log-sort Yard Cash Flow Analysis), has been constructed to aid in the pre-feasibility and financial feasibility analysis of log-sort yards. It is meant to be referred to concurrently with this documentation and is available for downloading at no cost from the Forest Products Laboratory's website at: http://www.fpl.fs.fed.us/documnts/fplgtr/fpl_gtr184/. The model is flexible, allowing up to 20 species and grades that each may be sorted into up to 19 products, giving a total of 380 different output possibilities. The mix of those species and grades can be allowed to change over time. Sort-yard operating hours and productivity and number and type of employees can be changed over time. Cash flows reflect automatic replacement of capital equipment when it is projected to wear out. Data on various pieces of capital equipment and equipment configurations can be stored so that cost comparisons can easily be made between different sorting systems.
