[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figures 1 to 2, in the embodiment of the present utility model, a multifunctional fumigation vapor debugging box includes a test box body 1. Inside the test box body 1, an A box 2, a B box 3, a C box 4, and a D box 5 are respectively installed. On the front of the test box body 1, a controller 6, a recorder 7, and control buttons 8 are respectively installed. On one side of the test box body 1, a medicine adding and detection operation panel 9 is installed. Inside the A box 2, the B box 3, the C box 4, and the D box 5, temperature sensors 10 connected to the recorder 7 are provided. Inside the A box 2, the B box 3, the C box 4, and the D box 5, temperature control components 12 connected to the internal heating and cooling unit 11 of the test box body 1 are provided. The A box 2, the B box 3, the C box 4, and the D box 5 are all connected with a sampling inlet 14, a sampling outlet 15, and a medicine adding port 16 through pipes. The sampling inlet 14, the sampling outlet 15, and the medicine adding port 16 are all installed on the medicine adding and detection operation panel 9. The A box 2, the B box 3, the C box 4, and the D box 5 are all connected with a discharge inlet 17. The A box 2, the B box 3, the C box 4, and the D box 5 are all connected to a discharge pump 19 installed inside the test box body 1 through pipes with discharge valves 18. The A box 2, the B box 3, the C box 4, and the D box 5 are all connected to a vacuum pump 21 installed inside the test box body 1 through pipes with negative pressure valves 20.

[0017] The A box 2, the B box 3, the C box 4, and the D box 5 have functions such as temperature control, pressure control, gas component control, and fumigant concentration detection, which can meet the fumigation tests carried out under different temperature, pressure, and gas component environments, and are particularly suitable for the development of fumigation treatment technologies for animal and plant products.

[0018] The test box body 1 regulates the temperature inside each box through the heating and cooling unit 11 and the temperature control component 12. The adjustable temperature range can be controlled between 5°C and 35°C, the temperature fluctuation: ≤±0.5°C, and the cooling rate: not less than 20°C / h under normal pressure. The pressure range inside each box is regulated by the vacuum pump 21 and the pipes with negative pressure valves 20: from -19.8 kPa to normal pressure, the pressure reduction time: from normal pressure to -19.8 kPa, within 30 minutes, and the pressure deviation: ≤±2 kPa.

[0019] When manufacturing the multi-functional fumigation steam conditioning test chamber equipment, the airtightness requirements for Chamber A 2, Chamber B 3, Chamber C 4, and Chamber D 5 are as follows: the time for the pressure in the working chamber to decay from 500 Pa to 250 Pa should be no less than 10 minutes. For the use of the discharge inlet 17, discharge pump 19, and discharge valve 18, the time to control the uniform circulation of the fumigant should be ≤ 10 min; the time to discharge to a safe concentration should be ≤ 10 min. Chamber A 2, Chamber B 3, Chamber C 4, and Chamber D 5 are four independent channels. The inner linings of the chambers are made of stainless steel and the total volume is not less than 200 L. The power supply used for the multi-functional fumigation steam conditioning test chamber is: single-phase 220V ± 10%, 50 Hz. The sampling inlet 14, sampling outlet 15, and chemical addition port 16 can be equipped with gas conditioning gas (oxygen, carbon dioxide) detection components and fumigant (methyl bromide, sulfuryl fluoride, phosphine) detection components. Chamber A 2, Chamber B 3, Chamber C 4, and Chamber D 5 are respectively connected to different sampling inlets 14, sampling outlets 15, and chemical addition ports 16, which is conducive to the separate regulation and detection of each sample located in different chambers.

[0020] Chamber A 2, Chamber B 3, Chamber C 4, and Chamber D 5 are all connected with pressure gauges 22, which are convenient for observing the actual indoor pressure inside each chamber. On the front of Chamber A 2, Chamber B 3, Chamber C 4, and Chamber D 5, there are chamber doors 24 with observation windows 23 installed through hinges, which are convenient for observing the changes of the samples inside each chamber.
