Embodiment Construction

[0023] The present invention will be further explained below in conjunction with the drawings and embodiments

[0024] Before the fruit undergoes quality inspection and grading, the temperature is lowered to the optimal refrigeration temperature, and the gas cooled to this temperature is sent to the fruit quality inspection and grading machine, so that the temperature of the fruit is always maintained during the quality inspection and grading process At that temperature.

[0025] The optimal refrigeration temperature is 0°C-10°C according to different fruits. Of course, due to the different habits of various fruits, the requirements for refrigeration temperature are also different. The best refrigeration temperature for fruits such as apples, pears, and peaches is 0°C, pineapples are 10°C, and citruses are 4°C.

[0026] The specific implementation method of the present invention is as follows:

[0027] Such as figure 1 , Figure 5 As shown, it includes a fruit quality inspection ...

Abstract

A method and apparatus for increasing the resistance of fruits to damage in their test and classifying procedure features that the temp of the fruits is lowered to the optimal cold storage temp, and a cooling unit is communicated via reflux tube, guide tube and throttle valve to the quality testing and classifying units for making their temp to be said optimal cold storage temp. As a result, the peel of fruit becomes harder and the respiration of fruit is reduced by 1-3 times.

Description

Technical field [0001] The invention relates to a cooling device, in particular to a method and a device for improving the ability of resistance to damage during fruit detection. Background technique [0002] Before the fruit enters the market, the quality should be tested and classified according to market demand, which is convenient for price evaluation according to the quality, which can increase the commodity value of the fruit and increase the income of farmers. [0003] At present, there are equipments for post-harvest grading of fruits at home and abroad. Such as: the MERLIN series fruit grading machine developed by the American Agricultural Technology Company (AGRI-TECH, INC., VA), the fruit quality intelligent real-time inspection and grading production line developed by Zhejiang University and so on. [0004] Existing fruit grading equipment runs at room temperature, which may damage the surface of the fruit, thereby affecting the quality of the fruit. In the existing i...
