Abstract

The present invention relates to a portable large thick-peel fruit internal quality optical detection apparatus. A purpose of the present invention is to use the apparatus to rapidly detect the internal quality of large thick-peel fruits in fields and other places, wherein the apparatus has characteristics of compact structure and easy use. The technical scheme is that the portable large thick-peel fruit internal quality optical detection apparatus is characterized by comprising an auxiliary function mechanism, an internal spectrum emission mechanism, an external spectrum emission mechanism, and a spectrum receiving mechanism, wherein the auxiliary function mechanism comprises an outer cylinder, a connection round disk and a heat elimination assembly, the external spectrum emission mechanism comprises two emission units, the internal spectrum emission mechanism comprises an inner cylinder, an inner cylinder end cover and an inner halogen lamp, and the spectrum receiving mechanism comprises three receiving units.

Description

technical field [0001] The invention relates to the technical field of optical detection devices, in particular to an optical detection device for fruit internal quality. Background technique [0002] With the improvement of people's living standards, consumers pay more and more attention to the internal quality of fruits such as sugar content and acidity when purchasing fruits. The time of picking melons and fruits in the field is closely related to their internal quality. Picking too early or too late is not conducive to the later sale and consumption of fruits. Therefore, it is very important to detect the internal quality of the fruit and judge the maturity. Compared with traditional detection methods such as manual identification and chemical analysis, visible / near-infrared spectroscopy has the characteristics of fast detection speed, no damage, low cost, and direct detection. It has been widely used in the research of rapid nondestructive detection of fruits. [0003...
