Description

technical field [0001] The invention relates to a device for nondestructive detection of fruit quality, in particular to a portable nondestructive detection device for sugar content of fruit with weighing. Background technique [0002] With the continuous increase of fruit production and the continuous improvement of people's living standards, consumers pay more and more attention to the internal quality such as taste, sugar content, acidity, etc. when purchasing fruits, and the sugar content of fruits is an important factor for evaluating fruit maturity and fruit quality. an important indicator. At present, the inspection of the internal quality of fruits is often based on destructive chemical analysis, such as anthrone colorimetry or sugar meter for sugar content, potentiometric method (pH meter) for acidity, and colorimetry and high-phase chromatography for vitamin content. These methods all have problems such as cumbersome sample preparation, long analysis time, high de...

AI Technical Summary

Problems solved by technology

Although a temperature sensor is arranged near the photoelectric detector and the light source in the design, and temperature compensation is considered in the detection model, there is still the problem of low detection accuracy caused thereby, and the cost of the device is increased. In addition Due to the difficulty of heat dissipation, there is also the problem of affecting the quality of the fruit

[0007] In addition, fruit weight is the basis for fruit measurement. No one has proposed a portable detection device that can simultaneously detect fruit weight and internal quality and sugar content.
