Instant, non-contact, precise moisture measurement in wood products is possible with MoistTech’s IR3000-W analyzer. The amount of moisture in wood products is a critical concern of the forest industry because excess moisture can have a large impacts on final product quality and production.
Wood manufacturers can adjust moisture levels based on real time information being displayed, lowering raw material and fuel costs, providing higher yields, and more uniform products.
Over 40 years of knowledge and experience in moisture management technology gives MoistTech the upper hand in offering the most advanced wood moisture sensors in the industry.
With thousands of installations worldwide with a wide variety of forest products, MoistTech offers both online for the continuous readings of NIR moisture measurement and laboratory NIR moisture sensors for spot tests near lines or in your quality control labs.
NIR (Near Infrared) moisture measurement is a non-contact measurement that offers clear advantages over the traditional methods, the most important being ease-of-use, the elimination of hazardous chemicals, and increased efficiency of product testing. With NIR analysis, all manual steps of collecting, drying and accurately weighing samples are eliminated. Real-time data is fed directly to the mills distributed control system for process control.
Wood Product Dryer Measurement
Efficnet dryer control is essential in reducing energy costs and maintaining a consistent product. Proper incoming moisture measurement along with feed rate can help prevent overloading the dryer.
Near-Infrared (NIR) moisture control allows mills to benefit from a reduction in fuel consumption and maximization of energy efficiency by reducing CO2 emissions during drying. Additionally, measurement of material at the exit ensures that material going to the blender if at the optimum moisture content for resin addition as well as optimizes moisture prior to the palletizer (10-20%).
Dust and board fires are also dramatically reduced with proper moisture control. 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.
The IR3000W sensor been extensively used within the wood products industry, making it ideal for process control of dryers, blenders and incoming raw material providing real-time moisture measurement. Installation is quick and simple and only needs the wood moisture sensor to be mounted a few inches above the product. MoistTech’s product database allows us to pre-calibrate the wood moisture sensor prior to shipment, allowing a plug-and-play operation.
Standard power requirements and all outputs are incorporated, the sensor provides extensive data through an ethernet connection or, if required, has several 4-20 ma outputs. Operator interface and digital displays can also be provided as additional equipment.
Wood Product Blending
Correct wood moisture content will allow for precise blending that in turn will reduce waste and provide significant cost savings. Many plants report that the savings alone pay for the cost of the moisture sensor 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 & Hog Fuel
The quality of raw material going into the mill is also important as accurate moisture content is needed to determine how much wood a mill is purchasing since much of the pulp wood is purchased on weight. Also, process monitoring is essential due to the variations of quality of the raw wood materials used.
An excess of moisture will affect resin coatings causing de-laminating and blown boards. Incoming raw material can be monitored to within 0.5% which allows the dryer personnel to prevent major process changes resulting in interruptions. Dryer in feed 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 and significant fuel cost.
