Abstract
Small-scale and hobby sawmill operators increasingly seek low-cost methods for drying lumber to moisture contents suitable for interior use, yet conventional kiln systems are often impractical due to capital cost, power requirements, and operational complexity. While air drying remains common at small scales, many operators require a controlled finishing step to improve dimensional stability and product value. Solar kilns offer an intermediate solution between air drying and conventional kilns; however, most published designs and performance data focus on systems with capacities far larger than those typically used by small-scale operators. Consequently, limited guidance exists for micro-scale solar kilns, particularly under variable seasonal conditions in humid subtropical climates.
This thesis addresses that gap by examining the design and performance of a low-cost, micro-scale solar kiln intended for hobby and part-time sawmill use in the southeastern United States. Chapter One documents the design, construction, and monitoring of a compact solar kiln and characterizes its internal temperature and relative humidity environment across multiple seasons. Chapter Two applies the same kiln to drying a charge of 8/4 Prunus serotina (black cherry) during the fall shoulder season, evaluating drying behavior and operational constraints associated with reduced solar input.
Rather than proposing optimized drying schedules or large-scale production solutions, this work focuses on documenting realistic performance expectations for micro-scale systems and identifying practical considerations relevant to small operators. Collectively, the thesis provides applied guidance on the capabilities and limitations of micro-scale solar kilns and clarifies their role as finishing tools in small-scale lumber production workflows.
