WOOD
PRODUCTS - Moisture Measurement and Control
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.

Dryer
Measurement:
Incoming 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 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 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 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.
The
MoistTech Sensor Advantage:
 |
Large
intense Quartz Halogen slight source |
 |
Optical system that
is several times more efficient than competitors |
 |
High speed Motor
- - 100s more measurements per second |
 |
No Product height

design |
The MoistTech IR-3000
is the only sensor that rejects false data such as spaces in the material
on the conveyor or gaps in the process flow. At line data and operation
can also be accessed using our "Bluetooth" system which is another feature
no competitive product has.
