Fruit quality fast detector

Abstract

The present invention provides a fruit quality fast detector including a housing, a fruit quality detection unit, a display and a central data processing unit, the display is arranged on the housing, the fruit quality detection unit includes a hardness testing module, the hardness testing module includes a fruit placement platform arranged on the housing and a vertical plate arranged on the fruit placement platform, the vertical plate is opposite to a pushing rod which is arranged on the housing and can stretch out and draw back along the horizontal direction, the pushing rod is provided with a pressure sensor, and the pressure sensor and the display are connected with the central data processing unit respectively. The hardness testing module is fast and easy to operate, short in detection time, and can effectively improve the detection efficiency.

Description

Technical field [0001] The invention belongs to the technical field of rapid detection instruments, and specifically relates to a rapid detection instrument for fruit quality. Background technique [0002] Apple has the reputation of "wisdom fruit" and "memory fruit". Apples are rich in sugar, vitamins, minerals, zinc and other nutrients, which have the effects of improving memory, improving intelligence and enhancing human immunity; and the influence of pesticide residues, heavy metal pollution, substandard sweetness, and immature fruit The quality of apples has been greatly reduced. Not only will they fail to achieve the above-mentioned effects after eating, they will endanger human health in serious cases. Therefore, the quality of apples must be quickly tested in all aspects of apple production, trading, and circulation. [0003] Indicators reflecting the quality of apples require the use of different instruments, which reduces detection efficiency and increases detection cost...

AI Technical Summary

Problems solved by technology

[0004] Through the detection of apple hardness, the maturity degree of apples can be judged, and the cultivation of fine varieties, picking time, processing time, collection and storage, export transportation, etc. can be reasonably grasped. Some of the fruit comprehensive testing instruments do not have a hardness testing module. At the same time, since the hardness testing instrument needs to use a push rod and move it, and the push rod is usually installed vertically, the overall volume of the instrument is larger, which increases the hardness testing. Difficulty integrating with other assays in a comprehensive assay facility

In addition, the existing hardness testing instruments still have the following deficiencies: 1) the existing hardness testing instruments are mainly operated manually, and the degree of automation is relatively low; 2) the push rod used usually needs to be inserted into at least half of the apple, And determine the maximum value as the hardness data from a small number of discrete pressure data points read during the insertion process, which not only takes a long time to detect, but also cannot well meet the hardness testing needs of apples in different states, resulting in the accuracy and reliability of hardness testing Poor sex
