Portable kiwi fruit sugar degree nondestructive testing device

Abstract

The invention discloses a portable kiwi fruit sugar degree nondestructive testing device, and belongs to the field of crops spectrum nondestructive testing. The invention is to provide a sugar degree nondestructive testing device which is suitable for kiwi fruit and stable in testing result. The nondestructive testing device comprises a shell, a master control module, a fan, a light source module, a thermal baffle, a spectrum testing module, a probe module, a measurement key, a display screen, a power switch, a charging battery, and a charging interface, wherein the light emitted from the light source module penetrates into the kiwi fruit to form diffuse transmission through the probe module; the diffuse-transmitted light is conducted to the spectrum testing module through the probe module; the master control module controls the spectrum detection module to acquire visible / near infrared spectrum data; and the master control module displays the kiwi fruit sugar degree obtained after data processing on the display screen. The nondestructive testing device disclosed by the invention can be used for postharvest classification of the kiwi fruit, and further can be used for growth monitoring of the kiwi fruit, is in favor of improving the sugar degree testing efficiency of the kiwi fruit, and increasing the economic benefit.

Description

technical field [0001] The invention relates to the field of spectral non-destructive detection of agricultural products, in particular to a non-destructive detection device for sugar content of kiwi fruit. Background technique [0002] The kiwi fruit is delicate and juicy, rich in nutrition, and loved by people. my country's kiwifruit planting area is the largest in the world. Sugar content is an important internal quality index of kiwifruit. It is not only an important basis for consumers to choose kiwifruit, but also the main basis for fruit growth monitoring and post-harvest grading. The traditional sugar content of kiwi fruit is measured with a sugar meter. When measuring, the kiwi fruit sample is first squeezed, and then dropped into the sugar meter for detection. The test will damage the kiwi fruit. Therefore, a device that can non-destructively detect the sugar content of kiwi fruit has become an urgent need. [0003] The method of predicting the sugar content of k...

Problems solved by technology

"The technical problem to be solved by this patent is: "The problem that traditional devices are too large to be carried

"The application did not explain the structure of the near-infrared detection optical fiber probe part. From the application, it is impossible to know whether the near-infrared detection optical fiber meets the requirements for kiwifruit infrared spectrum data collection; the device only completes the spectral data detection work, and also needs to transmit data. To the computer data acquisition system for further analysis, the sugar content data of the detection sample cannot be directly obtained, and the structure is complicated, so it cannot be used portablely

[0011] In summary, at this stage, the use of visible / near-infrared spectroscopy technology can achieve the purpose of non-destructive testing of kiwi fruit sugar content, but this method has not been applied to portable Non-destructive detection device for kiwi sugar content; at the same time, due to the complex structure of kiwi fruit, the measurement results of traditional standard diffuse reflection optical fibers are poor in stability, and cannot be used for the collection of kiwi fruit visible / near-infrared light data; the portable detection device described in the current related patents cannot solve the problem of kiwi fruit sugar content The problem of non-destructive testing, and these devices do not consider the applicability of the probe structure to the measurement sample and the stability of the measurement results, nor the influence of the heat generated by the light source and other devices on the spectral detection device, and the stability of the measurement results is difficult to guarantee
