Premier Applications

Blending Uniformity

Brimrose AOTF Technology is extremely fast (scans 16,000 wavelengths / second in order to give you 10 measurements / second), and is best for performing spectral analysis for products on conveyors and blenders. You can do more signal-averaging during very short collection times resulting in higher signal:noise spectra. Our solid state and robust components enable our spectrometers to be integrated directly to the blender for real-time measurement to determine when blending is complete and can stop, minimizing production time and cost to market of your products.

Brimrose worked with us to meet our extreme specification requirements for sensitivity, providing us the capability to reduce waste and costs. Without Brimrose, we would not have gone to market so quickly.

fluid bed dryer (fbd)

The AOTF-NIR spectrometer is integrated to measure moisture, proteins, fats, chemicals, or any other organic compounds simultaneously. The spectrometer can be mounted directly to the fluid bed dryer for in-line process monitoring. 

Our pilot application has returned well over six figures in the first eight months of continuous operation. We expect similar returns with the installation and commissioning of four additional units in like processes across the Americas Regions...

moisture measurement

Moisture measurement is an ideal application for near infrared spectroscopy. Moisture, fats, proteins, ash, and more is measured simultaneously. Our AOTF-NIR spectrometers are integrated into any manufacturer's processes without modifying the process. For example, we interface with your process controls to optimize the moisture content of your products.

This is a real time iterative approach that not only optimizes the desired output, but eliminates product rejections due to over and under drying.

Other applications

Brimrose has several decades of experience working with individuals and organizations to integrate our AOTF-NIR Spectrometers as a Process Analytical Technology (PAT) for in-line and at-line analysis. Our laboratory spectrometers support this integration. We will help you build your models with respect to your primary reference to meet your requirements to help you improve your quality control and consistency.
