[0022] As a further implementation of this embodiment, Figure 1-4 As shown, a stabilizing component is provided at the bottom of the wide-mouth bottle 2, and the stabilizing component includes a stabilizing groove 1, which is sleeved on the bottom of the wide-mouth bottle 2, and an annular buffer pad 8 is provided on the inner side of the stabilizing groove 1. The buffer pad 8 is provided between the inner side of the stabilizing groove 1 and the outer side of the wide-mouth bottle 2 to further protect the wide-mouth bottle 2. A trumpet-shaped stabilizing suction cup 7 is provided at the bottom of the stabilizing groove 1, and the stabilizing groove 1 is adsorbed on the experimental table by the stabilizing suction cup 7, so as to achieve the purpose of stabilizing the wide-mouth bottle 2, thereby avoiding the wide-mouth bottle 2 from being accidentally touched during the test and causing it to fall and break, protecting the safety of the wide-mouth bottle 2, and ensuring the safe conduct of the food respiration intensity measurement work;

[0023] When measuring the grain respiration intensity, the bottom end of the wide-mouth bottle 2 is inserted into the inside of the stabilizing tank 1, and the stabilizing tank 1 is adsorbed on the experimental table by the stabilizing suction cup 7, so that the wide-mouth bottle 2 can be stabilized, and a buffer pad 8 is arranged inside the stabilizing tank 1 and outside the wide-mouth bottle 2 to further protect the wide-mouth bottle 2;

[0024] Specific working principle:

[0025] When conducting a grain respiration intensity test experiment, first place the grain sample in the 3D printing cage 3, and mount the 3D printing cage 3 on the hook 6, then cover the mouth of the wide-mouth bottle 2 filled with barium hydroxide solution with a rubber stopper 5, and plug the rubber stopper 5 with a drying tube 4 filled with soda lime, then plug the bottom of the wide-mouth bottle 2 into the inside of the stabilizing tank 1, and use the stabilizing suction cup 7 to adsorb the stabilizing tank 1 on the experimental table, so that the wide-mouth bottle 2 can be stabilized, and a buffer pad 8 is set on the inside of the stabilizing tank 1 and the outside of the wide-mouth bottle 2 to further protect the wide-mouth bottle 2. Sodium lime is used during the experiment. The ash absorbs the carbon dioxide in the air that enters the wide-mouth bottle 2 through the drying tube 4, so that oxygen continuously enters the wide-mouth bottle 2, ensuring the normal respiration of the sample. After 24 hours, the carbon dioxide released by the respiration of the sample in the bottle is absorbed by the barium hydroxide solution to generate barium carbonate and water. Remove the rubber stopper 5 and drop 1 to 2 drops of phenolphthalein indicator. Use standard oxalic acid solution to titrate the remaining barium hydroxide in the bottle, and then do a blank experiment with only a certain amount of barium hydroxide added without adding a sample as a control. The difference between the amount of oxalic acid used in the blank experiment and the experiment with the sample represents the amount of carbon dioxide released by the sample, thereby determining the respiration intensity of the grain.

[0026] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
