the number as well as placement of the samples. Kiln samples are used when drying lumber by moisture con-tent schedules and for developing time-based drying schedules. Moisture Content Schedules By far the most important purpose of kiln samples is to enable a kiln operator to dry a kiln charge of lumber by a specific moisture content schedule. Hardwood lumber is usually dried below the fiber saturation point before kiln drying, but occasionally green lumber from hard-to-dry species is placed directly into the kiln. Lumber drying begins at mild conditions followed by a series of species-specific temperature increases and lowering of relative humidity, termed the kiln schedule.
Nine steps to setting up a kiln. Lumber drying is an attractive valued-added business with plenty of opportunities for well run, small- and medium-sized drying operations.

"This book describes the fundamental basis of kiln-drying technology, enabling forest companies to improve their drying operations as high-quality timbers become scarcer and former wasteful practices can no longer be tolerated.
It covers wood structure, moisture in wood, moisture movement and stress development on kiln-seasoning lumber boards. If however the kiln conditions settled at dry bulb 52°C/wet bulb 47°C, giving a wet bulb depression of 5°C, the relative humidity would be only 75% and could be too severe for satisfactory drying.
With automatic control systems and under frequent air flow reversal the correct positioning of the sensing equipment is an important consideration.

drying system you need or how best to design and build your kiln chamber, we won’t give you a selling pitch: we’ll give you a realistic analysis of the numbers, and a straight answer on what type of system will work best for you.
To answer some of your questions on lumber drying, we’ve prepared this booklet. It takes a look at things. since drying it too fast creates excess end and surface checking. Drying too slow is also costly since it will tie up a kiln for too long. It is, therefore, the responsibility of the kiln operator to control temperature, humidity, circulation and ventilation to achieve the best drying rate without creating kiln degrade.
- 2. system other than moisture added by the drying lumber. This method of drying is most popular for oak and other hard to dry species. Low Temperature Dehumidification Drying Dehumidification drying is a form of kiln drying.
With a dehumidifier, moisture is removed from the dryer by condensing the moisture on cold coils. When the water condenses. DRY KILN Bob Pope December 2, USNR ’ Counter-Flow Continuous Kiln. C-F-C Kiln Milestones • First Lumber CFC Pollard Lumber • First Pole CFC T.R.

The subject of kiln drying lumber is probably one of the most hotly debated subjects in the forest industry today. It seems that there are as many theories about how lumber should be dried as there are people involved in kiln drying.
This is an indication of the complex nature and the many factors that influence the removal of moisture from wood. The World Leader in Lumber Drying Systems SinceNyle has been building the world’s most energy efficient lumber dryers.
We pioneered the development of dehumidification drying as a practical, economical drying method. Today our systems set the standard for. type and condition of kiln, quality of drying required, and cost considerations, no schedule presented in this chapter can be considered ideal.
The schedules are pre sented as guides for kiln operators in developing sched-ules best suited for their own particular operation. In general, the schedules presented are conservative and. This book shows you why and how the entire manufacturing and drying process-from beginning to end-affects the final quality of lumber from your dry kilns.
It focuses on the challenges in high temperature drying of Southern Pine, a species known to warp, but applies to any kiln s: 1. Almost all defects in lumber drying occur at very high moisture contents (MCs). After air drying, the lumber is put into a kiln to achieve the low final MCs desired.
Quality losses in air drying. Don't start without a copy of the Dry Kiln Operator's Manual, a very comprehensive book available from the USDA, many kiln associations, or kiln vendors like us.
If you are drying hardwoods, then you really need the more practical text DRYING HARDWOOD LUMBER; if you are drying mainly oak lumber, DRYING OAK LUMBER; for Southern pine, DRYING.
“Dry Kiln Operator’s Manual”1 and “Air Dry-ing of Lumber.”2 This report does not attempt to repeat all details from those vol-umes. Rather, it presents new information on these methods and on accelerated air drying, as well as other methods available for drying hardwoods.
1 Rasmussen, Edmund F. Dry Kiln Operator’s Manual. At present, no single book adequately covers a basic understanding of wood book satisfies the need for such a work.
It describes drying in practice. This the fundamental basis of kiln-drying technology, to enable forest companies to imFrove their drying operations as high-quality timbers become scarcer and of yesteryear can no longer be : Paperback. Solar heated lumber dry kilns have been key to our success for 25 years at Timbergreen Farm, a acre family forest business in SW Wisconsin.
Solar Cycle kilns are so simple and effective that this technology opens a new large door to small woodworking businesses around the world - in the tropical rainforests, natural forests, young forest plantations, and urban forestry.
You have probably never seriously considered kiln drying your own lumber before, believing it to be too expensive or too complicated to undertake on a small scale.
Prior to the introduction of the Ebac Small Scale Lumber Dryers this was true. Kiln drying was for the world of specialists: a confusing maze of kiln. No previous drying experience or training is necessary. Instruction will include lectures and demonstrations. Wood moisture relations, kiln operation, lumber handling and storage, and drying schedule preparation will be emphasized as it relates to drying hardwood lumber.
