Industrial Hemp Quality Control

MoistTech is supported by the original manufacturers of Near-Infrared (NIR) technology in the industrial moisture industry manufacturing a range of on-line sensors & at-line instruments for moisture measurement and real-time moisture process control for numerous applications. Insensitive to material variations such as particle size, material height & color, our moisture sensors provide continuous, reliable readings with zero maintenance and a one-time calibration with a non-drift optical design allowing operational personnel to confidently make immediate process adjustments based on real-time measurements. 

Hemp is used in the production of an array of products including plastics, rope, oils, foods and beverages. Hemp fibers have also been converted into two types of biofuel: biodiesel and ethanol. Building products from hemp are also very durable: hempcrete, biodegradable plastics and wood replacements are all useful hemp applications.

All of the common hemp applications as well as the seed, have a vital parameter which influences quality and storage life of the overall product – moisture control. The moisture content is closely associated with several aspects of the manufacturing process and can play a large role in the overall quality of the finished product.

Byproducts/Waste

During fiber processing, the core fiber is saved and usually used to make paper, horse bedding, or construction materials. Moisture content is a key factor to this process and most hemp producers recycle the core fiber by removing dust, then baling and packaging. At the correct moisture percentage, the dust can be pressed into pellets and used, or sold, as a fuel source. 

MoistTech is a highly skilled leader in the measurement of moisture during processing. Our sensor calibrations, measurement wavelengths, algorithms and sensor optical requirements are pre-set at the factory to the needs of each customer and process. Typical accuracy is ±0.1% moisture in the 0-35% range. Typical analog range is 0-50% moisture, and the outputs can be adjusted to optimize PLC or recording requirements.
