Regional Training Seminar in Jackson, MS

Dependent upon level of interest, Wagner Meters is tentatively scheduling a one-day regional training seminar for March 17, 2015 in Jackson, MS. Hotel location and address will be provided to registrants after registration is full, or no later than two weeks prior to scheduled date.
 
This combination of hands-on and presentation-based training will focus on Wagner’s APEX and Omega-generation of in-line moisture measurement systems, with the primary goal being to provide your personnel with a thorough review of the correct usage and maintenance of your Wagner system. If your company has an older-style Wagner system or even none at all, you are also welcome to attend and learn about the current generation of Wagner systems.
 
This one-day seminar is $95.00, and seating is limited, first-come first-served, so register now before seating fills up. Continental breakfast and lunch will be provided.
 
Additionally, mills within a 150-mile radius of Jackson can request either a half-day or full-day onsite visit during the week of the seminar to have a Wagner technician look over their Wagner systems, troubleshoot, calibrate or provide training. The service call rate for these onsite visits is greatly reduced from Wagner’s standard service rates. This great opportunity for reduced-rate onsite visits is also first-come first-served.
 
Seminar Week Reduced Onsite Rates:

Half-Day Onsite Visit:               $   995.00
Full-Day Onsite Visit:               $1,495.00
 
These prices are easily half of what you would expect to normally pay for an onsite visit with travel
expenses.
 
To register, just contact one of the Wagner personnel below, provide a purchase order number or credit card, and let us know if you also want an onsite service/training visit sometime that week.

Dry Kiln Control / Re: Kiln heating
« Last post by HencoV on January 21, 2015, 11:11:24 AM »
What can you do if a kiln isn't heating fast enough? This can be done either 1. adding more energy/boiler capacity or by 2. decreasing energy loss or 3. optimizing the drying schedule for minimum values

If nr1  is not an option, nr 2 has been checked and rechecked, nr 3 could become an option for advanced kiln managers and kiln analysers

Kiln control systems are designed to control on maximum values, eg, maximum dry bulb, vent when maximum WB value (vent set point) is exceeded. To control on minimum energy is a completely different ball game.

It is about balancing energy input, and getting rid of moisture, while not compromising the highest temp achievable to maintain maximum moisture movement. ie. managing the venting strategy in such a way that temperature is not lost, while still getting rid of moisture to a point where the available energy is not exceeded by the energy take up(TDAL) as timber dries.

General Discussion / Re: Flexible Kiln Baffles
« Last post by rfosters on January 21, 2015, 11:02:08 AM »
Jon developed the idea at IFI back in the ninetys IFI let him patten the idea but I think he sold the patten.
I worked with Jon during this time and up until he retired.  But A few of the Stimson mills still use this type of overhead baffle.  Priest River stud mill is one of them and it has to be done correctly or you wont be happy with the result.  Double thickness works best and you can get the baffle brushes from Motion Ind. but make sure you get the high temp stuff or the planer will scrape the melted remains off the top of the units.
Most of the Stimson mills were heading in that direction.  Personally I wouldn't use anything else. maintenace is almost nonexistent and the brushes conform to any layer height differences.

Stacking/Sorting Wood / Re: Stacking Frozen Lumber
« Last post by rfosters on January 21, 2015, 10:52:59 AM »
Good luck on the frozen lumber.  We used to solid stack green pine and CDR boards the only think that worked when unstacking was a dead blow hammer (big one).

But we never did try calcium chlorid spray, that might work or what ever they use on the raods these days.

Dry Kiln Control / Re: Kiln heating

operating on demand venting helps, keeping the the vents closed maybe not until you are totally up to temp but close. with this though you have to have tight control of your venting. slow and easy when you start or you will lose most of what you gained in the first place

I have no working experience with the brush type baffles however I have done some airflow checks in a kiln where they were being used and 400 ft/min was leaking through and this kiln had about 700 ft/min through 3/4" stick slots

Other than what's suggested in this article below can you offer any additional advice for avoiding mold, staining, and insect problems?

For lumber mills in Canada, seasonal transitions play an enormous role in the treatment of the log resource to be dried, and make it necessary to modify kiln-drying schedules. A deep understanding of the characteristics of each species, including sap movement (changes from one season to another), is essential whether the mill is processing hardwood or softwood.

In addition, the climatic conditions present in a given season or during seasonal transitions are quite different from region to region.

Sap Movement and Other Ambient Conditions

If the outside temperature is below 32⁰F, there is no discernable movement in sap (water). As the temperature begins to rise, the sap will start to slowly move up to the surface.

As summertime approaches, factors such as temperature, relative humidity and wind speed will come into play. Therefore, it is necessary for mill personnel to have a plan to protect the rough sawn lumber from defects such as discoloration and mold or insect damage before it ever reaches the kiln.

Stacked Lumber with StickerIn regions where the relative humidity is low and greater wind speeds are the norm, mill personnel should be concerned about damage to the wood while it is on stickers waiting to be kiln-dried. The damage could be in the form of checks or cracking on the ends or faces of the boards.

In other areas of the country where higher temperatures, low airflow, and high humidity are present during the summer season, fungal growth and staining are of prime concern. Unless lumber is stored for a prolonged period of time, insect infestation is less of a worry because insects and any unhatched eggs will not survive the kiln.

Effect of Seasonal Transitions on Kiln Scheduling

Most mills have a set of summer and winter schedules for drying. In summer months, summer schedules are followed. During the seasonal transition from summer to fall, kiln personnel will often begin to see charges of lumber coming out of the kiln with average moisture content readings exceeding their target MC. This will trigger modification of the kiln-drying schedule to accommodate the transition to the colder winter months.

When it is springtime or fall temperatures are generally cooler and it may be wet. Sap is just starting to begin to flow. However, where it is much warmer, the sap flow is much faster. Kiln operators may have to make very quick scheduling adjustments because of rapidly-changing climatic conditions, especially in recent years.

Protect Lumber in the Yard Before Kiln Drying

Every precaution that can be taken out in the yard will help kiln operators develop an effective schedule that will produce the highest-graded lumber possible. In the end, if a mill continually turns out premium quality lumber, then customer satisfaction will remain high, and of course that maximize profit for the mill.

Mill personnel have several methods/treatments at their disposal to help prevent lumber degrade (especially end splits, discoloration and damage due to insect infestation) while it awaits the kiln:

1. End Coating Lumber
Hardwood mills will generally apply a wax-like product such as the well-known Anchorseal® or another compound to the ends of logs/lumber. It is most often sprayed on the ends of boards after they have been sawn into dimensional stock in the sawmill.

Other mills coat the logs upon arrival, especially if for economic reasons the mill has chosen to stockpile logs to be sawn at a later period of time. In addition, a lot of mills spray a fungicide on the ends of logs before the sealer is applied.

Softwood dimension mills typically do not end coat lumber due to the fact that commodity softwood lumber typically sells for substantially less than hardwood species. Hardwood mills can better absorb the cost of protecting their lumber from end splits and the development of mold and inner wood fungal attack.

In addition to end coating, hardwood mills may choose either to air dry lumber for some time, or to implement a pre-dry process before kiln drying.

Lumber is placed in a pre-dry building and fans continuously blow across the stacks of wood. This step is taken before subjecting the boards to a more aggressive drying environment (the kiln).

2. Sprinkling Logs With Water
Log Pile with Sprinklers OnSprinkling log decks with water is done in various parts of the country to help protect lumber from developing defects before it is kiln-dried. A large lawn sprinkler-type unit is used by lumber mills to keep stacks of lumber wet, especially during hotter times of the year. Water evaporation helps keep the logs slightly cooler, slowing down the instance of fungal growth. When logs are very wet, it is more difficult for fungus to get established because they need oxygen for growth; it is also harder for insects to lay eggs.

In the West, some pine-producing mills will also use this method to retard blue staining, which commonly can be seen on lumber in the summer months.

3. A Regional Strategy to Protect Lumber from Discoloration
At some eastern mills, birch, maple, and pine logs that are to be sawn into boards earmarked as specialty products are frozen to ensure white color. The short logs from winter-cut timber are placed in ground depressions and sprayed with water to form a coating of ice. The frozen log decks are covered with sawdust, wood shavings, or other available insulating material so that the wood remains frozen well into the summer months when further processing will commence.

A Special Note to Mill Personnel

Hats off to all mill personnel who work very hard to complete the pre-kiln processing of lumber, meet the challenges of seasonal changes and use all methods economically possible to protect boards against developing defects (end splits and discoloration, to name a few). Not to mention using proven strategies to stop mold and fungal growth and insect infestation from invading good quality lumber.

Readers now have a sample of the challenges and complex decision-making processes awaiting a kiln operator. However, when all of the necessary tools are used and critical regimens followed, the efforts of mill personnel will be rewarded by producing the best-grade lumber possible.

News / U.S. softwood lumber production up 4.7%
« Last post by admin on January 14, 2015, 08:28:41 AM »
U.S. sawmills produced 26.578 billion board ft. (bbf) (62,7 million cubic meters) of softwood lumber in the first 10 months of 2014, an increase of 4.7% from 25.388 bbf (59,9 million m3) a year earlier, according to the latest Lumber Track report by the Western Wood Products Assn. (WWPA) of Portland, Oregon.

Western U.S. sawmills contributed 11.965 bbf (28,2 million m3) to the 10-month total, up 4.5% from the 11.453 bbf (27 million m3) produced a year earlier, while output from southern sawmills was 13.378 bbf (31,5 million m3) – a gain of 4.9% from 12.755 bbf (30 million m3 a year earlier.

Production in October alone was 2.826 bbf (6,6 million m3), a gain of 1.5% from 2.784 bbf (6,48 million m3) in the previous year, and 7.0% higher than September’s output of 2.642 bbf (6,2 million m3).

The U.S. consumed 35.728 bbf (84,3 million m3) of softwood lumber in the 10-month period, a 7.1% gain over consumption a year earlier of 33.364 bbf (78,7 mil. m3).

U.S. production as a percentage of practical capacity averaged 84% in the first 10 months, compared with 80% in the same period a year earlier, while in Canada, the average remained level with the previous year at 79%.

U.S. inventories slipped 0.2% in October to 2.949 bbf (6,95 mil. m3) from 2.955 bbf (6,97 mil. m3) a year earlier.
