Feb 09, 2018 However, if you kiln dry hardwood lumber that has already been air dried, the process is much more forgiving. Most species of hardwood lumber can be safely dried this way, once the moisture content is 20% to 25% or less. The fact is, most of my stacks of lumber air dry to 15% moisture content before entering the kiln.
drying, is to heat the wood and increase its vapor pressure. Essentially this is what conventional steam kilns do. EMC at 68 F (20 C) (Figure 1) Another way of increasing the difference between the vapor pressure of the air and that of the wood is to lower the vapor pressure of the air. This is what
Dehumidification Dry Kiln Shipping containers are either 20 ft or 40 ft long and both are sizes are available in a standard or insulated (for refrigeration) design.

Feb 11, 2015 I can attest to 3-6 day drying times out of these kilns. My good friend built one and I can tell you it works fantastic. A wood stove heats the container. Fans move the heat and air around. An exhaust fan purges the container of moisture once every two hours.
Additional phases can be added for phytosanitary treatment (56 degrees for 30' in center of the wood) which can be combined with a drying cycle or separately. (optional) The anti-freeze system is another main function :it avoids the freezing of the water inside the heat exchanger when the kiln is not working and electric panel is on.

We air dry for about one month, then rack the wood in the kiln and use a dehumidifier and small fan. With the insulation, we can use the kiln in the winter (in Ohio) as the returned heat from the de-humidifier and the fan motor are sufficient, or we can add a small heater. The kiln is nearly air-tight and the de-humidifier drains through the floor.
We normally heat kilns easily to a 160 F temperature, which is required by most state laws to kill any bugs in the wood. We have kilns being heated up to over 200 F for faster drying which happens very quickly with 4000 CFM of heat blowing into the kiln.

Aug 22, 2017 A container kiln was the right decision for me at that time. Without question, if I had to build another container kiln I would seek out a reefer unit and convert it, as opposed to insulating a steel container. We dry a lot of oak and the tannin's are hard on the steel.

Apr 14, 2019 Vacuum kilns can be the fastest method to dry and most efficient with energy usage. The goal of the vacuum is to boil water at a lower temperature at which it evaporates, resulting in stronger wood. By drying at a low temperature the process accelerates the drying time without harming the wood.
the kiln can reach 180 degrees plus when it is -40 outside, it still will not melt the snow on top. actualy filling the kiln is important you need to force the air through the wood, not just suround the wood with hot air. kiln baskets should fill inside of the container. i use urathane insolution to seal and insulate the container.
