    NIR — real-time measurement of fat, protein, moisture and ash without off-line analysis.

NIR Spectrometer System

The Dupps NIR (Near InfraRed) spectrometer system is an innovative solution that accurately measures the component content of rendering process streams in real-time, without time-consuming and costly off-line analysis.

NIR spectroscopy measures the wavelength properties of light reflected by a material to determine that material’s characteristics and composition. Applied to rendering process streams, NIR analysis reveals detailed information about the product as it is being rendered – including protein, fat, moisture and ash content – so that vital production control and product qualities can be optimized and waste minimized. Moreover, unlike traditional slow and sometimes inaccurate off-line lab testing, NIR analysis can be done continually, accurately and in real-time.

The Dupps rendering NIR spectrometer was developed by Carl Zeiss Spectroscopy GmbH — a firm with over 20 years experience in designing and building spectrometer systems for process industries. The Dupps system’s sensor and other hardware were specifically designed and built to operate in the harsh environmental conditions encountered in rendering operations.
