Abstract

The invention discloses a portable fruit internal-quality detection device using an optical detector. The device has a box body structure, and the side face of a case is provided with a displayer. A single-chip microcomputer, a fan, a power supply, a division plate, a fruit support table and the optical detector are arranged in the case. The optical detector completely integrates a light source, a light collecting element and an electronic element, is put just below the support table and can directly detect a near infrared spectrum of fruits. The device has the advantages of simple structure, small size, good stability and convenience and fastness in detection, collects spectra in a diffuse reflection mode, and is suitable for rapid non-destructive detection on site.

Description

technical field [0001] The invention relates to a portable fruit internal quality detection device, in particular to a portable fruit internal quality detection device using an optical detector, which belongs to the technical field of nondestructive detection of agricultural and forestry products. Background technique [0002] Soluble solids (SSC) refers to sugars, acids, minerals, vitamins, etc. that can be dissolved in water. It is one of the important indicators of the internal quality of fruits, so how to accurately and quickly determine it is of great significance. At present, the destructive chemical detection method is still the main method for the internal quality detection of fruit, but its cumbersome sample preparation, long detection time, and the need for professional operation, which greatly limit the application scope of this method. The near-infrared detection of fruit internal quality refers to the measurement of parameters such as sugar content, acidity, vit...
