<p><P>PROBLEM TO BE SOLVED: To eliminate the time required to adjust the focal point of light, maintain a constant focal length at all times, and shorten the time required to detect residual agricultural chemicals in a fruit sorting line system capable of detecting residual agricultural chemicals. <P>SOLUTION: The fruit sorting line system 1 includes a mounting stand 6 for mounting vegetables and fruits; a feeding transfer means 2 for transferring the mounting stand; and a light projection and reception part 3 for irradiating mid-infrared rays to agricultural chemical components in the surfaces of the vegetables and the fruits and detecting them by spectral analysis on their reflected light. By providing a hole part for a lower part of the mounting stand 6 and projecting and receiving light through the hole part, it is possible to detect agricultural chemical components while the vegetables and the fruits are mounted to the mounting stand. It is thereby possible to eliminate the need for the adjustment of the focal point of light for each individual since the distance from the light projection and reception part 3 to the surfaces of the vegetables and the fruits is constant and substantially shorten the time required to determine residual agricultural chemicals. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
