If you would like to add a specie, let us know if there are scientific publications that we can calibrate it to. Otherwise, choose a specie with similar drying characteristics, set the dry density and adjust the drying rate knob to calibrate to your experience. The schedule creator will also take these settings into account.
Application overview
The process of drying lumber is a delicate balance of science and operational expertise. Our Lumber Kiln Simulator is a powerful desktop tool designed to bring clarity to this complex process, providing a practical way to explore, understand, and visualize what happens inside the kiln.
At its core, the simulator is a dynamic model grounded in the fundamental principles of heat and mass transfer. It incorporates detailed psychrometric calculations to accurately model the properties of moist air, combined with established wood physics to simulate how lumber responds to its environment. This robust, first-principles approach ensures that the simulation provides a faithful representation of the real-world drying process.
The simulator offers comprehensive flexibility, allowing you to configure both conventional batch kilns and continuous progressive kilns (transverse or longitudinal). Recognizing that no two boards are alike, the tool lets you define the initial statistical distribution of moisture content, density, and thickness, providing a more realistic model of a true lumber charge. You can then apply custom-built drying schedules to see how the wood reacts over time.
As a simulation runs, you can visualize the changing moisture content on a board-by-board basis and follow the drying curves, temperature drop across the load (TDAL), and the evolution of the moisture distribution. This allows you to safely and efficiently explore "what-if" scenarios, analyze the impact of parameter changes, and gain a deeper intuition for the intricate dynamics at play.
The schedule creator feature creates a great starting point for a successful kiln schedule for high quality results in the shortest time possible. Whether for training, process analysis, or schedule optimization, our simulator serves as a practical bridge between theoretical principles and real-world application, empowering a better understanding of lumber drying.
