[0030] By adopting the above technical solutions, the storage rack on which the bulk drugs are placed is placed into the box body 1, steam enters the first steam heat dissipation pipe 11 and the second steam heat dissipation pipe 12 through the air inlet pipe 8, then enters the return pipe 13, and finally is discharged through the air outlet pipe 9; the high temperature generated by the steam is dissipated into the box body 1 through the first steam heat dissipation pipe 11 and the second steam heat dissipation pipe 12, so as to dry the bulk drugs in the box body 1; the high temperature generated by the electric heater 14 can also dry the bulk drugs; while the first steam heat dissipation pipe 11, the second steam heat dissipation pipe 12 or the electric heater 14 dissipate high temperature, the plurality of motors 3 drive the louver fans 15 to rotate rapidly to generate air flow, and the air flow can drive the high-temperature gas in the box body 1 to flow rapidly, so that the high-temperature gas can frequently contact the bulk drugs quickly, thereby improving the drying efficiency of the bulk drugs.

[0031] In this embodiment, one end of the first steam heat dissipation pipe 11 away from the second steam heat dissipation pipe 12 is fixedly connected to the air inlet pipe 8, and the air inlet pipe 8 extends to the outside of the box body 1 and is connected to the steam transportation pipe;

[0032] One end of the second steam radiating pipe 12, which is far away from the first steam radiating pipe 11, is fixedly connected to the reflux pipeline 13. The reflux pipeline 13 is located above the interior of the box body 1, and one end of the reflux pipeline 13, which is far away from the second steam radiating pipe 12, is fixedly connected to the air outlet pipeline 9; the air outlet pipeline 9 extends to the outside of the box body 1 and is connected to the steam recovery pipeline.

[0033] By adopting the above technical solution, during the drying process of the bulk drug, the moisture contained in it will be evaporated by high temperature; the evaporated moisture will be dispersed into the box body 1.

After the air extraction pump operates, the humid air in the box body 1 can enter the pipe 6 through the through hole 18 at the top of the box body 1, thereby removing the moisture in the box body 1. By using the air extraction pump in cooperation with the pipe 6, it can ensure that the inside of the box body 1 is always in a dry state, prevent the moisture in the box body 1 from entering the bulk drug, and ensure the drying effect of the bulk drug.

[0039] Three temperature detectors 16 are arranged in the box body 1, and the three temperature detectors 16 are evenly distributed in the box body 1. The three temperature detectors 16 can detect the temperature in the box body 1 in real time. When the temperature distribution at each position in the box body 1 is uniform, then place the bulk drug into the box body 1, which can ensure that the drying speed of the bulk drug at each position is the same, thereby improving the drying efficiency of the bulk drug.
