Overview
The InfraLab Near Infrared (NIR) Food Analyzer has been providing production and quality management personnel with rapid, reliable and accurate data on samples collected for at-line or in-laboratory testing. Testing for moisture levels, fat & oil content or protein levels takes a matter of seconds thus replacing older, more time-consuming and expensive methods. Now the InfraLab’s technology has advanced even further with the introduction of a Top Loader analyser for powders, ground products, beans, grains, semi-solids and sheet products. In addition, the new Top Loader has the ability to measure colour thus ensuring that production of the ideal product output is achieved. The Top Loader provides results of multi-component analysis within seconds and data can be stored within the memory for further analysis.
Operating Principle
The Top Loader provides a much higher level of result consistency using a sapphire-based sample pot within which the sample is placed. The material being analysed is therefore flat, free of surface contamination and presented reliably every time with almost zero variation between measurements. It also includes a new feature of colour measurement using colour data outputs in industry standard colour scales including CIE L*a*b*.
The InfraLab Food Analyzer operates on the concept that specific wavelengths of light are absorbed by moisture, fat, and proteins. Through the emission of light pulses at distinct known wavelengths and comparing the absorption rates to an internal reference, it becomes feasible to precisely ascertain the extent of absorption for each wavelength. Employing advanced signal processing, the algorithm transforms the infrared (IR) signals into an output proportionate to moisture, fat, or protein content, utilizing a calibration curve. Notably, the measurement remains unaffected by variations in process conditions such as particle size, temperature, ambient lighting, and humidity fluctuations.
