A method for detecting mentholated tobacco, comprising irradiating tobacco containing menthol and a fluorescent taggant with radiation and observing the tobacco for fluorescence from the taggant. A system and method for detecting and separating mentholated tobacco from non-mentholated tobacco within a product stream is also provided.
摘要:
At a conveyor forefront portion, velocity distribution of an airflow is provided. The velocity distribution is wind velocity distribution in a vertical direction of an airflow from a surface of an upper rectifying plate to a surface of a conveyor at the conveyor forefront portion, and has a maximum value in a range of less than 10 mm downward of the vertical direction from the rectifying plate surface. Moreover, a ratio obtained by dividing the maximum value by a wind velocity in the vicinity of the surface of the conveyor is 4 or more, and 12 or less. In a range other than the range of less than 10 mm, the airflow has a wind velocity equal to the wind velocity in the vicinity of the surface of the conveyor.

A system for detecting oil contaminated product and foreign matter within a product stream is provided. The system includes a first conveying means for delivering a product stream; a first detection apparatus for detecting oil contaminated product, the first detection apparatus positioned proximate the product stream, the first detection apparatus including a high intensity infrared light source directed at the product stream; and a high speed NIR spectrometer sensor tuned to detect a reflected signal from a taggant disposed in the oil of the oil contaminated product; a second detection apparatus for detecting foreign matter within a product stream, the second detection apparatus positioned proximate the product stream, the second detection apparatus including a light source for illuminating the product stream and a detector for detecting light reflected from the product stream; and a controller for determining whether the product stream contains oil contaminated product or foreign matter by monitoring signals obtained from the first detection apparatus and the second detection apparatus.
摘要:
A method for removing foreign matter from an agricultural product stream of a manufacturing process. The method includes conveying a product stream past an inspection station; scanning a region of the agricultural product stream as it passes the inspection station using at least one light source of a single or different wavelengths; generating hyperspectral images from the scanned region; determining a spectral fingerprint for the agricultural product stream from the hyperspectral images; comparing the spectral fingerprint obtained in step (c) to a spectral fingerprint database containing a plurality of fingerprints using a computer processor to determine whether foreign matter is present and, if present, generating a signal in response thereto; and removing a portion of the conveyed product stream in response to the signal. A system for detecting foreign matter within a agricultural product stream is also provided.
摘要:
The device for inspecting separately conveyed tablets or capsules has a guide device for guiding the separately conveyed tablets or capsules, which defines a predetermined tablet pathway, and a heating element designed as a hotplate, which is arranged in an area of the guide device. The device further has an IR sensor for detecting radiation in an infrared range arranged opposite the heating element such that the tablet pathway passes between the heating element and the IR sensor, and an evaluation unit connected to the IR sensor and adapted to compare actual measurement values of the IR sensor with at least one predetermined nominal measurement value.

摘要:
A cost efficient and reliable method for online sorting of special glass which works independent of the color of glass and the shape of the material. The scrap glass stream to be detected is thereby irradiated by UV absorption or transmission values of the scrap glass stream, more specifically of the material-specific UV absorption edges and “UV-cutoff” frequencies, with reference values obtained before from standardized material laboratory inspections. If special glass is being detected, blowing nozzles disposed downstream of a detector unit divert the special glass toward a predetermined location where it is deposited. There can also be a system which includes a radiation source, a detection unit, an evaluation and control unit and a removal apparatus.
摘要:
A method of sorting mined material to separate the mined material into at least two categories is disclosed. The method comprises exposing particles of the mined material to microwave energy and heating the particles depending on the susceptibility of the material in the particles. The method also comprises thermally analysing the particles using the temperatures of the particles as a basis for the analysis to indicate composition differences between particles and then sorting the particles on the basis of the results of the thermal analysis. The method also comprises compensating for temperature variations in the mined material that is supplied to the method.
