Wood Moisture Applications
MoistTech
has the most advanced online sensor for the non-contact measurement
of moisture in wood products such as fiber, sawdust, hog, fuel, wood,
flakes and wood particles.
Online instant measurement and control produces significant
advantages to the forest products industry. Benefits such
as. . .
- Reduced energy usage
- High quality Product through instant accurate moisture
control
- Reduction in fire and explosion risk
- Plant production efficiency monitoring
- Prevention of board press explosions
- Dryer control
- Blending monitoring for control of moisture and resin
- Increased productivity
- Lowest cost most advanced sensing
- Highest performance operation
- Reduce downtime
- Low cost sensing with minimal maintenance
MoistTech online and at line moisture instrumentation for
the forest product industries, such as:
Dryer Measurement:
Incoming wood moisture measurement together with feed rate can
prevent overloading the dryer. Measurement of material at
the exit ensures that material going to the blender if at
the optimum moisture content for resin addition. Moisture
measurement at the exit of the dryer can save significant
amount of fuel while more importantly prevent fires or explosion
risk. Trend analysis that is incorporated into each sensor
can be used to give operator knowledge of problems before
they happen. MoistTech's advanced sensor is the only sensor
that has all these features.
Blending:
Product input to the blender is critical to the plant operation.
Correct wood moisture content will allow for precise blending addition
that in turn will reduce waste and provide significant cost
savings. Many plants report savings alone pay for the cost
of moisture / resin control within weeks of installation.
At the exit of the blender the process can be refined to confirm
the correct resin addition thus preventing press explosions
from high moisture in the forming process. Blown boards can
be eliminated and precise moisture/resin control will ensure
excellent board properties. Trend analysis that is incorporated
into the software in each sensor will allow the operator to
prevent problems before they cause production interruptions
Raw Material and Hog Fuel:
Incoming raw material can be monitored to within 0.5%. Which
allows the dryer personnel to prevent major process changes
resulting in interruptions. Dryer infeed can be controlled
thus allowing the output to maintain precise moisture levels
to within 0.1% accuracy. On hog fuel applications the material
can be blended for a more efficient combustion. Again significant
fuel cost saving can be the result of installing MoistTech's
IR 3000 continuous non contact moisture sensor.
Installation Calibration:
MoistTech IR-3000 has been used extensively within the forest
products industry. Installation is quick and simple and only
needs the wood moisture sensor to be mounted a few inches above the product
or where needed an optical window or sampling system can be
used [**** See details on Optical Window or Sample system
****]. Standard power requirements and all outputs are incorporated.
The sensor provides extensive data through Ethernet connection
or if required has several 4-20 ma outputs together ever other
common output. Operator interface and digital displays can
also be provided.

MoistTech's product data base allows us to pre- calibrate
the wood moisture sensor. With known product moisture samples each instrument
can be calibrated within a few minutes prior to shipment.
Field installation then becomes even simpler. The IR-3000
stores calibrations that can be transferred to other instruments
on similar process applications. Each IR-3000 sensor is identical,
which then allows calibration settings to be used on all instruments
on the same application ranges.
