Device and method for testing fruit interior quality

Abstract

The invention provides a device and a method for testing fruit interior quality. The device comprises a detection sensor and an amplifier, wherein the detection sensor comprises an exciting element and a receiver; the exciting element is connected with the input end of the receiver; the output end of the receiver is connected with the amplifier. The device and the method have the beneficial effects of being suitable are suitable for performing nondestructive testing on various kinds of fruits, sample pretreatment is not needed, and testing time consumption is short; the results tested by the device for testing the fruit interior quality can be output in multiple forms and can be displayed on a native machine; the device also can be directly connected with monitoring equipment in an on-line form so as to easily realize high-speed on-line real-time monitoring and control; the device also can exchange the data with mobile internet; the device for testing the fruit interior quality is small in size, convenient to carry and easy to operate and low in production cost, and has a simple structure; moreover, popularization and application are facilitated.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a fruit internal quality detection device and a detection method. Background technique [0002] With the improvement of people's living standards, more and more people have increased their pursuit of dietary health, especially diabetic patients. They have special requirements for the sugar content in each meal and the amount of fruit intake. not excluded. And for healthy people, when buying fruits, some want to buy fruits that are fragrant, sweet, crisp, and rich in water; some want to buy not only sweet but also a certain sour taste. Of course, no one is willing to buy a fruit that is sour and lacks water, especially a fruit that weighs a few kilograms at a high price. If it is not sold well by accident, it can range from tens of yuan to hundreds of yuan, and the price is too high. In order to buy delicious fruits, developing a variety of detection instruments for rapid and...

AI Technical Summary

Problems solved by technology

Such as a portable fruit sugar non-destructive testing device with weighing, a portable quality testing device that simultaneously detects fruit sugar content and hardness, a portable quick tester for fruit sugar acidity, a reflective quick tester for fruit sugar acidity, etc., but the current instruments Or the device adopts the technical means of infrared refraction or visible light analysis, because the light cannot enter the pulp, when the light encounters the material, it will refract and diffuse on the surface of the material, and only when the pulp is thin will there be transmission. However, it is very difficult to know the specific content of substances in the fruit

Moreover, the current instruments or devices have complex structures and high production costs, which are not conducive to popularization and application.
