| 摘要 |
The invention relates to an apparatus (10, 110) for detecting defects on the outer surface of foodstuffs (P) that comprises an optical system (40, 140) configured to analyse the surface of the foodstuffs (P) and detect the presence of any defects, wherein there are provided application means (20, 120) adapted to distribute a dry or fluid contrast material (23, 123) onto the surface of the foodstuffs (P), such that said contrast material can penetrate into any surface defects, and removal means (30, 130) adapted to remove excess contrast material from the surface, so that it remains inside the aforementioned surface defects only, said contrast material making the defects detectable by the optical system. |
