2/9/2018 A dehumidifier, a 1,500-watt electric heater with a tip-over shutoff switch and a steam generator very common home center and Rockler supplies are used to control lumber drying. A dehumidifier (DH) removes moisture from the kiln chamber. By setting the relative humidity (RH) on the dehumidifier, you can control how often it runs.
Step 4 Build the Kiln. After a few months, bring the wood indoors and finish the drying. To build the kiln lay poly (clear plastic roll) on the ground and then build a frame with 2x4 studs on top of it for the lumber to rest on. Leave enough space to have a standard household dehumidifier at one end, and a
I run a dehumidifier during this period to lure the moisture out of the boards, and capture the water so that it doesnt accumulate on your windows (or cast iron tools). Without this, excessive moisture can build up in the room if you are drying a sizeable quantity of wood.
Jan 20, 2012 Freshly sawn hardwood lumber is perishable, with delays or improper handling often resulting in lost revenues for producers. Green boards are usually dried as a first step in their utilization, making this process critical to value retention and addition. Two or three months of air drying followed by several days in a steam heated kiln has been the traditional procedure used by wood product ...
Feb 14, 2010 The firewood kiln manufactures claim to dry firewood in 24 hrs and I guess I dont have any problem believing you could dry a split in the oven over 24 hrs, why not in 2 weeks at 77-85 F (as claimed), with a dehumidifier lowering the RH and circulating the air through the wood.
Jan 30, 2020 The typical desiccant dehumidifiers used in restorative drying are capable of drying air to single-digit grains per pound (GPP) levels, which is about 4%RH at 70F. These are dew points several degrees below freezing. LGRs under the best situations cannot dry areas below a 32F dew point therefore desiccants can create a much drier environment.
There are a few different ways of drying wood. Stacking your wood up and letting the air flow around the wood is, of course, the oldest, and still very popular today, but if you want to accelerate the drying process you could use solar, dehumidification and high heat drying such as with a kiln. All of these are methods that work when drying wood.
Gene Wengert, forum technical advisor. Home dehumidifiers can work but they are designed for operation to about 45-50% RH, which is not low enough for 6% lumber. The components are not designed to last in an acidic atmosphere and they are designed
Apr 08, 2017 In a professional DH kiln, the final climate for oak is 120F and 40t over-dry it at that rate. The air flow rate through your stacks should be about 350FPM. It is a good idea to sterilize the lumber at the end of the kiln run. This can be done by heating above 133F for 4 hours (measured at the core of the wood), or at 120F for about 7 10 days.
Aug 27, 2008 The heat will be enough to dry the lumber, but you also can put a small dehumidifier in the kiln to speed the process. The conventional wisdom is you cannot use a home dehumidifier to dry wood, especially with acidic woods such as oak that will corrode the coils.

Sep 27, 2011 Yes, all the dehumidifier does is to suck the water out of the air, but that dry air is what dries the wood... ALWAYS. There are numerous large-scale dehumidification kilns all over the country that work on the same principle - lowering the relative humidity inside a controlled space, and using fans instead of wind to keep the dry air circulating over the wood surfaces.

The dehumidifier provides a small scale method of drying wood at a reasonable cost. As a general guideline, the dehumidi-fier may be most practical at production rates below 50 MBF per month. Above that level, the generation steam in a wood waste or natural gas boiler is
Kiln Drying. The kiln process involves the drying of wood in a chamber where air circulation, relative humidity and temperature can be controlled so that the moisture content of wood can be reduced to a target point without having any drying defects. The most commonly used kilns are conventional and dehumidification kilns.
Sep 29, 2016 I havent done it, but Ive read about it being done with lumber. It takes a lot of electricity so it would be a costly way to dry firewood. Also the moisture in such an environment is corrosive, and tends to destroy dehumidifiers not specifically designed for drying wood

Wood-Mizer dehumidification and solar wood kilns range from 300 to 35,000 board feet capacity for drying lumber. Kiln drying lumber is a simple, cost effective method recommended for anyone who wants to increase profits by selling dried lumber.

Apr 23, 2021 When lumber companies kiln dry their wood, they do so in a controlled environment using carefully monitored temperature and humidity levels in order to avoid over-drying or under-drying. This is critical because it allows the wood to dry to the correct MC for its ultimate intended use, thereby enabling the wood to maintain stability and dimension.
Jul 31, 2008 Jul 31, 2008. 15. Dario said Dehydrator dries from outside in. Microwave is by exciting the water molecules. The water expansion as it turns into steam is what dries the wood. The big difference, is the (almost) equal moisture in the wood (inside and out).
Drying Defects in Sawn Timber. Seasoning or drying defects in sawn timber are second only to knots in reducing the quality of processed wood. Once timber has dried below the Fibre Saturation Point (FSP) which is about 28% moisture content, the wood begins to shrink. Shrinkage of wood is anisoptopic.
The FD100 is a high performance drying unit designed to extract maximum water at the lowest cost. It operates at temperatures up to 55C. The best compromise between drying speed and reliability insures the dried wood is of the highest quality. EIPL recommends a drying rate of 1% per day or less when drying 1 hardwood.
Sep 23, 2021 By using a dehumidifier, you are hurrying the drying process, and the plaster can either start cracking immediately or over time. Also, it does not provide a gentle drying process. The air from the dehumidifier is too dry, and it can cause damage to other materials, especially if you have wet insulation or wood in your walls that will also be ...
