METHOD AND DEVICE FOR IDENTIFYING INORGANIC PARTICLES WHICH CONTAMINATE LOADS CONTAINING ORGANIC PARTICLES

摘要

The present invention describes a method for identifying inorganic particles which contaminate loads containing organic particles, characterized by including the steps of collecting a sample of the load of organic particles, magnetizing the sample, illuminating the sample, capturing images of the sample and sending the images to a computer for processing, analyzing, and evaluating the images, and finally diagnosing whether the load is contaminated, retaining or releasing the load. The device for identifying inorganic particles which contaminate loads containing organic particles, characterized in that it comprises at least one magnetic field source, at least one lighting source, at least one photographic camera, and a computer.

1. A process for identifying inorganic particles that contaminate loads containing organic particles, comprising:
collecting a sample of the load of organic particles, in a dynamic or static manner; magnetizing the sample with at least one magnetic field with frequency between 500 Hz and 2 KHz; illuminating the sample with at least one source of illumination in the range from 0 to 850 nm; capturing images of the sample with at least one photographic camera configured to register at least 60 frames per second, with shutter speed of at least 1/2000 s with frequency between 40 and 70 Hz, and calibration of three ranges: ultraviolet from 80 to 90 nm; visible from 380 to 779, and infrared from 780 to 850 nm; sending the images to the computer for processing, evaluation and judgment of the image; diagnosing the sample as being contaminated or not; blocking or releasing the load.
