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

Abstract

The invention discloses a portable near-infrared fruit internal quality detection device with adjustable light spot. In the chassis, the light source part is installed on the right side of the chassis through the light source bracket; the detection unit is installed on the left side of the chassis through the detection bracket, open the flip cover of the chassis, and put the fruit into the sample room in the detection unit; the turntable of the turntable mechanism is installed in the Between the light source part and the detection unit; the circuit board for controlling the processing unit is installed under the light source bracket, and the embedded computer for controlling the processing unit is installed on the upper surface of the chassis. The present invention adopts halogen tungsten lamp as the original light source to emit continuous wavelength spectrum, and the spectrum information of multiple bands can be obtained through the optical fiber, and the automatic collection of dark field, reference and fruit spectrum information is realized through the control of the turntable by the steering gear; The device is installed in a closed chassis to avoid the influence of external stray light on the detection process. The chassis wall is provided with cooling fans and cooling holes to ensure the temperature inside the chassis, which improves the spectrum collection efficiency and detection accuracy.

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 at the forefront of the world, but due to the low level of post-harvest fruit processing and treatment, 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 producing country. Sugar content plays a leading role in fruit quality. It not only affects the sweetness and color of the fruit, but also is the basic raw material for the synthesis of nutrients such as vitamins and carotenoids. At present, the internal quality analysis methods of fruits have the disadvantages of destroying samples, complex operations, long time consumption, high cost and inability to realize online detection....

AI Technical Summary

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.
