Abstract

The invention discloses a portable quality detection device for simultaneously detecting the sugar content and hardness of fruits. The device of the invention includes a signal acquisition part, a signal transmission part and a host part. Ordinary detection devices have long detection time, high detection cost, low detection accuracy, and are not easy to carry. The invention integrates many components together, and has a compact structure and is easy to carry around; a fan is installed in the main box to dissipate heat, and the device can be used for a long time; a spring is added to enhance the sealing between the fruit and the optical fiber probe, The detection accuracy is improved; it can meet the needs of fruit growth process monitoring, ripening period prediction, and fruit sugar content and hardness classification. The touch screen of the device is changed to a touch screen, which is easier to operate and faster in detection speed. It is suitable for the internal quality of fruit sugar content and hardness. On-site rapid non-destructive testing. The invention has the advantages of compact structure, small volume, simple operation and the like, and can simultaneously realize rapid non-destructive detection of two indexes of fruit sugar content and hardness.

Description

technical field [0001] The invention relates to a device capable of non-destructively detecting the relevant quality of fruits, in particular to a portable quality detecting device for simultaneously detecting the sugar content and hardness of the fruit. Background technique [0002] With the continuous improvement of people's living standards, consumers pay more and more attention to the internal quality of fruits when purchasing fruits, and the sugar content of fruits is an important indicator for evaluating fruit quality. At present, chemical analysis methods are usually used to detect the internal quality of fruits, such as anthrone colorimetry or sugar content meter to detect sugar content, potentiometric method to measure acidity, and colorimetric method and high-phase chromatography to measure vitamin C content. Although these methods have high detection accuracy, the sample preparation process is cumbersome, the detection time is long, the detection cost is high, and...
