OIL DETECTION PROCESS AND APPARATUS

摘要

A process for detecting oil or lubricant contamination in a manufactured product, the process comprising adding a fluorescent taggant to oils or lubricants contained in processing machinery for said product, conveying said product past an infrared detection apparatus, irradiating said product with infrared radiation from said detection apparatus as it passes the detection apparatus, and detecting infrared radiation emitted from said irradiated product.

主权项

1. A system for localization of oil contamination, comprising
(a) an inspection station for tobacco rods having a conveyor for advancing successive tobacco rods or pairs of tobacco rods; and (b) an infrared detection apparatus, said infrared detection apparatus including: (i) a high intensity infrared light source directed at tobacco rods and (ii) a high speed NIR spectrometer sensor tuned to detect an emitted signal from a taggant disposed in the oil, wherein said infrared detection apparatus is positioned proximate said conveyer at a distance effective to enable detection of reflected IR radiation as each advancing successive tobacco rod or pair of tobacco rods is irradiated.
