Torrified Wood Moisture

Product Consistency

Torrefaction of wood uses high temperatures to change biomass properties to make a better fuel quality for combustion or gasification. It creates a dry product that will not rot. This makes it easier and cheaper to transport and to store. Creating pellets or briquettes from wood waste makes it lighter, drier, and more stable than the biomass from which they are created.

Forest residue and urban wood waste may contain as much as 20-50% moisture. During the torrefaction process, the biomass is heated in an oxygen-depleted environment to 200-300C to remove the moisture and create a higher energy content. The resulting material has 1%-6% moisture.

To keep consistency during the process, MoistTech has developed the IR-3000-W near infrared (NIR) moisture sensor that is made for a rugged factory environment. It collects thousands of moisture readings per second and transmits them to either a controlling laptop or a computer network that can process them and make real-time corrections to the dryers on the line so that the end product will be consistent and high-quality.


Unsurpassed in performance, our sensors can accurately measure  moisture within tenths of a percent of most applications


MoistTech sensors withstand the test of time and are low to zero maintenance


Rely on MoistTech’s NIR moisture sensors to never drift or need re-calibration


A moisture measurement system is essential for the production process and in some cases will pay for itself in less than 30 days

State-of-the-Art Equipment

MoistTech has used their more than 40 years of experience as the industry leader in moisture measurement to develop a new state-of-the-art moisture sensor, the IR-3000-W. With this sensor:

There is no maintenance or calibration needed. It is set at the factory before shipping
It is not affected by particle size, color, or height—even small gaps between product samples do not trigger an alarm

  • Conveyor belts and screws do not affect the results
  • The sensor is unaffected by temperature or humidity
  • It provides an extreme accuracy of ±.01% moisture

This state-of-the-art sensor can be connected to the company network or any laptop. It is Ethernet or RS232 compatible and Windows-friendly to allow for real-time control of your manufacturing line and immediate analysis of the data.

What is the Solution?

We’ve combined our decades of experience and knowledge with feedback from our industry partners to create a moisture sensor capable of taking instant, non-contact measurements of moisture, temperature, and other vital levels with the utmost accuracy. When it comes to moisture sensors, the IR-3000 is the most advanced system available.


Locate the point in the production process in which measuring moisture will be the most crucial and beneficial. Identify how you will use the moisture measurement data for improvements and if it will tie into your PLC.

Remember this could involve more than one installation point!


A closed loop process is achieved by incorporating a moisture measurement system into the manufacturing process. Developing a proactive solution to moisture control will avoid costly downfalls. 


MoistTech’s experts will assess your specific application with lab tests, calibrations and accuracy results to ensure our equipment will peform for you. All of our sensors are pre-calibrated prior to being shipped to create a plug-and-play operation for the end-user.

Understand the Process

Many biomass materials are produced as byproducts, residues or wastes from some other process, operation or industry. Most of these have a valuable energy content that can usefully be channeled into fuel. This also has the benefit of keeping the material out of a landfill. This includes wood, food waste agricultural residues, industrial waste and co-products, and aerobic plants. Some foods are specifically grown to produce energy, like corn. MoistTech Corp. provides industrial sensors to measure and control moisture in almost any type of product
