  • Contaminant detector for food inspection
    Patent number: 7450686
    Abstract: A contaminant detection machine (1) including a conveyor (3) which causes an object under inspection (79) to pass through a plane (48) of emitted x-ray radiation. The plane is generated by an x-ray tube (55) that emits a lateral beam, thereby permitting the distance (88) between the x-ray tube and the object under inspection to be reduced. A photo diode arch mounting assembly (104) is placed above the object under inspection and is mated to a collimator assembly (125) that also serves as the mounting bracket for the x-ray generation assembly (38), thereby preserving optical alignment between the photo diode detector array (28) and the emitted x-ray plane (48). The detector array (28) scans the object under inspection (79) so as to produce a continuous series of discrete lines, each line being analyzed by an image processing unit (116) to determine the presence or absence of a contaminant.
