Portable near-infrared fruit internal quality detection device with adjustable light spots

Abstract

The invention discloses a portable near-infrared fruit internal quality detection device with adjustable light spots. In a case, a light source part is installed on the right side of the case through a light source bracket; a detection unit is installed on the left side of the case through a detection bracket, and fruit is placed into a sample chamber in the detection unit by opening a lifting cover of the case; a rotary table of a rotary table mechanism is installed between the light source part and the detection unit; and a circuit board of a control processing unit is installed below the light source bracket, and an embedded computer of the control processing unit is installed on the upper surface of the case. The portable near-infrared fruit internal quality detection device disclosed by the invention adopts a halogen tungsten lamp as an original light source to emit a spectrum with continuous wavelength, spectral information at multiple wavebands can be acquired through optical fiber, and automatic collection of dark field, reference and fruit spectral information is achieved through the control of a steering engine on the rotary table; and the device is installed in the airtight case, so as to avoid the impact of external stray light on a detection process, and the case wall is provided with a heat dissipation fan and a heat dissipation hole, so as to ensure the temperature in the case, and improve the spectral acquisition efficiency and detection precision.

Description

Technical field [0001] The invention relates to a portable fruit internal quality detection device, in particular to a portable near-infrared fruit internal quality detection device with adjustable light spots. Background technique [0002] In recent years, my country’s total fruit output has been in the forefront of the world. However, due to the low level of fruit post-production processing and processing, the annual fruit export volume only accounts for about 3% of the total output, which is extremely disproportionate to my country’s status as a major fruit producer. Sugar content plays a leading role in fruit quality. It not only affects the sweetness and color of the fruit, it is also the basic raw material for the synthesis of vitamins and carotenoids and other nutrients. At present, the internal quality analysis methods of fruits have disadvantages such as damage to samples, complicated operations, long time-consuming, high cost and inability to achieve online detection.

Problems solved by technology

This device has the advantages of being compact and easy to operate, but the near-infrared tube with a fixed wavelength is irradiated to different parts of the fruit separately, and the obtained fruit information is very limited and different, and the detection accuracy is not high.
