Conjoined determining device for respiration intensity of agricultural products and use method

[0043] When this patent is manufactured, if figure 1 As shown, the gas filter container 1, the water vapor filter container 2, the fruit holding container 3, the first three-way pipe fitting 7a end, the gas absorption bottle 4, the second three-way pipe fitting 8a end, and the flow meter are connected by a gas pipeline. 5. Pipeline connections are used in turn, and the first three-way pipe fitting 7b end, the solenoid valve 9 and the second three-way pipe fitting 8b end are connected with a gas pipeline, and the time relay 10 is connected between the solenoid valve 9 and the power supply. The gas pipeline behind the filter 2 can be divided into multiple paths through the first distributor pipe fitting 11, and connected to the corresponding fruit holding container respectively, and other components in sequence, and finally connected to the vacuum pump 6, and the fruit holding container can be installed in the incubator Body 13.

[0045] A joint measuring device for the respiratory intensity of agricultural products, which consists of a gas filter 1, a water vapor filter 2, a fruit holding container 3, a gas absorption bottle 4, a flow meter 5, a vacuum pump 6, a first three-way pipe fitting 7, a second A three-way pipe fitting 8, a solenoid valve 9, a time relay 10, a first distributor pipe fitting 11, a second distributor pipe fitting 12, gas pipelines and wires, wherein the gas filter container, the water vapor filter container, and the fruit holder The container, the first three-way pipe fitting 7a end, the gas absorption bottle, the second three-way pipe fitting 8a end, the flow meter and the vacuum pump 6 are connected in sequence by gas pipelines, the first three-way pipe fitting 7b end, the solenoid valve and the second The ends of the three-way pipe fittings 8b are connected sequentially by gas pipelines, and the power supply, time relay 10 and solenoid valve 9 are connected sequentially by wires.

[0048] How to use the combination measuring device for respiratory intensity of agricultural products:

[0049] When in use, the solenoid valve is normally open, the absorption bottle is filled with quantitative absorption liquid, a certain quality of agricultural products is put into the fruit holding container and sealed well, the power is turned on, the gas flow meter is adjusted to fix the gas rate, and the power is turned on , this stage is the gas balance stage. After the time set by the time relay (such as 0.5h), the solenoid valve 9 is closed, and the device automatically switches to the test stage. After the time set by the test, such as 0.5h, the power supply is stopped and the end Gas absorption test process, then take out the liquid in the absorption bottle, use chemical method to titrate and calculate the CO released by fruit respiration according to the following formula 2 Gas content, and then calculate the respiratory intensity value of the test fruit. The follow
